vilepickle.com: Repeating blocks of template code in Drupal 8

jeu, 15/01/2015 - 19:06

I've had some trouble using Twig's include statements in Drupal 8 theming.  I'm not sure if this is a bug since it's at Beta 4, but it's sort of annoying.  I include my content areas in page.html.twig in a separate include file in Drupal 6 and insert it into the area I need.  For example, if I have a 3 column layout, I'm changing the Bootstrap classes from "col-md-12" to "col-md-9" and "col-md-3" (for a sidebar) if the sidebars have content in them.  Inclu

Modules Unraveled: 129 Automation Tools with Solomon Gifford - Modules Unraveled Podcast

jeu, 15/01/2015 - 14:44
Published: Thu, 01/15/15Download this episodeUse Cases
  • Okay, I can already see huge benefits of utilizing these tools. But, I’d love to get your opinion on what the benefits are for Developers/Site-builders/Themers?
    • There are two big benefits as I see them, and another not so apparent. First, a lot of these tasks are repetitive. And things like copying a database may take a bit of time. Or merging code. Or running tests. Etc. Anything that you can automate means time you can spend on other things. Second, not everyone is as experienced - or maybe they don’t have the permissions - to execute all the tasks. You don’t want mistakes, you don’t want to give everyone permissions. So you figure out the best way to do it and then you automate it. The last reason is not as obvious. I think a lot of times we hack things together in our development environments to get it working - but then may run into issues later on. We don’t spend the extra time because its temporary. By spending a little extra time getting it right, we have created a reusable pattern that we can use on our next project. By encapsulating our best practices, we not only have a quicker setup, but we have a better one too.
  • Perfect. So, save time by automating tasks like copying a database. Prevent mistakes by limiting who has permissions to execute tasks, and automating them so that even those who do have permission can’t introduce user error. And by setting up a process that uses best practices, creating new environments is faster, and better than if I had to try to remember all of the steps myself.
    • Exactly. And I’ll add, ansible can be used for each of installation, configuration, and orchestration. The examples we’ve talked about so far are orchestration - moving databases, code, etc. It can also be used to install Apache, Mysql, Mongodb, etc. Any set of system commands that are repeatable.
  • Oh... So if you’ve got a server that you have full access to, you could actually wipe and rebuild the entire server AND Drupal site? We’re not limited to just configuring the Drupal site?
    • Exactly. And throw in Vagrant into the mix and now you can do that on your local machines using Virtual machines. Immagine spinning up a brand new VM and within a few clicks you have your entire development environment with a fresh drupal install all ready for you on a VM.
  • Now, I do wonder who this is more geared toward. Developers, Site-builders or Themers. I understand that each of them can use these, and would probably help them all with their daily tasks, but who do you see benefiting the most from these tools. Or, do you have examples of people in each category that you know of that are using them?
    • I think all three benefit from automation. For example, in a previous life where I didn’t use Ansible, my themer was insanely good at theming, but when it came to running commands remotely on a server to check out his work, he was a fish out of water. I wish I had written an Ansible playbook so that he could check his code out onto staging. Or even better, if I had set up Jenkins to run an Ansible playbook to automatically check it out his work each time he committed. He wouldn’t have had to wait on me, sometimes a few days if I was not around. That said, he would not have been able create the ansible playbook.
    • As for who is using Ansible, well, Twitter does - they use it to roll out updates across their hundreds of machines. And of course BlackMesh, the hosting company I work for, also does. The product Cascade I mentioned uses ansible and Jenkins to do a lot of the things we talked about today, only we set it up so you don’t have to.

Drupal Association News: A Few Things to Unwrap on Drupal's Birthday

jeu, 15/01/2015 - 14:07

Happy birthday to Drupal! On this day in 2001, Drupal 1.0 was released.

This milestone is the perfect time to talk about some of the findings of our recent community survey. The survey findings offer a window into what community members are thinking as the project matures and evolves. It also gives us at the Drupal Association a way to better understand what we're doing right and what we could be doing better. There aren't many surprises (and that's a good thing), but all of the findings are educational. Here are three results we thought were particularly interesting and insightful.

Drupal 8 Will Be Broadly Adopted


In the survey, about 80% of respondents said they either plan to start using Drupal 8 as soon as it is released, or plan to adopt it at some point after release. Another 8% said they did not have specific plans to adopt, but do plan to evaluate Drupal 8.

 

 

 

Drupal.org Remains an Important and Heavily-Used Tool


The overwhelming majority of respondents said they use Drupal.org more than once per week. Most also say they are satisfied or somewhat satisfied with the site. While that result is encouraging, it does not change the important mission to improve the experience of the site and make it a better tool for everyone from first time visitors to those who spend the majority of their working time on the site.

 

 

 

 

We Need to Create Broader Awareness of Drupal Association Programs


Community members who took the survey have great awareness of DrupalCons. Awareness of the work we are doing on Drupal.org seems to be steadily growing. But awareness is relatively low for Community Grants and our Supporter Programs that provide a way for organizations to give back to the Project. That awareness is clearly something we need to improve to promote transparency.

Bluespark Labs: 5 Technologies to focus on in 2015

jeu, 15/01/2015 - 05:58

Last year we wrote about 5 technologies to focus on in 2014. Last year’s article is still worth a read. Many of the things on the 2014 list are still very relevant.

In keeping with the best of yearly traditions, we want to follow up with the 5 technologies worth your attention in 2015. These are not bleeding edge technologies. Rather, these are technologies or platforms or ideas that are starting to mature and are worth investing your time and getting ahead of the curve.

DevOps & Security

If 2014 was anything, it was the year of security incidents, hacks, cracks and general information insecurity. In addition to the ones that actually made the headlines, Drupal suffered its own infamous moment during the so-called "Drupalgeddon". A vulnerability that if not fixed exposed your site to a critical attack.

Bluespark was one of a handful of shops that addressed the issue within minutes of the incident, which meant that clients hardly suffered. Drupal sites that did not benefit from the same care were exposed and, at worst, compromised.

What these security incidents highlighted is the need for site owners to have effective processes in place to update websites and servers. That points to developing an effective DevOps practice around your site. At Drupalcon Amsterdam, Bluespark talked about the value that DevOps generates. Part of that is precisely being able to deal with security incidents quickly. Security incidents cannot be prevented. The key is to be able to react quickly to them once vulnerabilities go public. Effective DevOps do just that.

Web Everywhere

The past year has seen a proliferation of devices that are internet-connected and aim to augment what our laptops, tablets and phones already do. In 2015 we are going to see the Apple Watch land on people’s wrists and Samsung has announced that every device it produces will be connected to the internet.

It’s like we’re living in the future.

At the same time, Amazon has launched tools such as AWS Lambda that allow you to effectively react to a variety of events through services.

The opportunities and possibilities for customer engage are about to explode in a way only previously hinted at. And if you’re not taking advantage of this new ecosystem, your competitors will be.

There are still many, many questions about this new ecosystem. What can you do with the new products and services? How are people going to use them?

More importantly for you, though, are the systems that run your web infrastructure ready for these new developments? Are your web content management system and web-based services able to manipulate content and perform actions in a way that can take advantage of these new devices?

Web Everywhere means that overall engagement strategies need to be defined, content strategies refined and content management systems fine-tuned to produce the right message and appropriate interaction. After all, people might not be going to your website from their fridge, but that doesn’t mean that having an internet-connected fridge is pointless.

Content-Driven Commerce

Many ecommerce sites are finally starting to catch on to a fundamental truth about sales: it’s not about the transaction, it’s about engagement. And how do you engage your audience? Certainly not by throwing out sale after sale. People are getting bombarded with promotions, their inboxes are getting clogged with the latest deals. It's time to take a step forward. Sort out how you can stand out from the crowd and connect with an audience that wants to make a purchase, though they aren't necessarily interested in being sold on something.

And that's the problem. If all your doing is selling, then you’re missing the point. Many e-commerce sites are so focused on the latest deal -- on the close -- that they forget a fundamental aspect of selling: telling a great story. People want to engage with a meaningful brand. They want a story that compels them to buy. A few brands are picking up on this, though not nearly enough.

Drupal is in a unique position to drive Content-Driven Commerce forward. Platform is one of the biggest challenges companies face when trying to integrate content and commerce. Drupal (along with Drupal Commerce or Acquia Commerce) tightly integrates both the commerce and content pieces of a website, making it easier than ever to craft stories that can drive conversions.

Context-Rich Systems

Last year we also talked about personalization for websites and experience management, which is really just another way to talk about context -- albeit a simple form of context.

Context-Rich systems go deeper than personalized websites, though. They are systems that pull in a number of diverse signals about the user and their context -- from their location, to the weather, device they are on, speed they are traveling. And like personalized websites, context-rich systems can adjust content, display, and input methods based on the user’s current situation. They will allow better feedback for the user and they allow the user to perform more through the website by linking together disparate services seamlessly.

In 2015, these systems will start to form as people bring more and more internet-connected devices (creating a personal ecosystem) into the home and business. In the past, when companies have tried to take advantage of Context-Rich Systems, they have applied old paradigms of understanding (hence why internet-connected fridges are the butt of many jokes) to the new technologies. But the companies that realize the possibilities in a way that doesn’t disrupt their customer’s lives, they will truly leap ahead.

Visualization

One of the technologies we mentioned in the 2014 article was deep analytics. Well 2014 has only increased the possibilities to collect even more data from more sources. The next step is to ensure that data is correlated correctly and visualized in ways that transform into useful, actionable information.

After all, what’s the use of data if you don’t know what to do with it?

Visualization technologies will become mainstream in 2015, and websites should expect to have information analyzed and presented in a variety of different ways so as to fit their needs. Vizualization libraries such as D3.js and search engines such as Solr have reached a level of maturity that allows for them to be fully and effectively exploited now.

2015 will be...

Every year it seems like new technologies are hyped. Different visions of the future are trotted out as the “next big thing.” We’re definitely excited about these technologies and think that, over the next few years, they have the potential to really change the landscape of e-commerce and technology, in general. We encourage you to do your own research into the technologies and tell us what you think. More importantly, though, think about how you can make use of these technologies in your own business. If time and money weren’t an issue, how might you use these technologies to give your boost your business ahead of the competition?

Dries Buytaert: Drupal retrospective 2014

mer, 14/01/2015 - 12:43

It's that time again. Time to look back at 2014, and to look forward to 2015. For Drupal in 2014, it was all about Drupal 8. As Drupal 8's development enters its fourth (and hopefully, final) year of development, it's a good time to reflect on all the work achieved by the Drupal 8 team so far, and to talk about Drupal 8's momentum heading into the final stretch to the release.

Drupal 8 will have 200 new features. Among the larger features that I'm excited about are the responsive design, HTML5 support, the native web service support, the much improved multilingual support, the configuration management system, a built-in WYSIWYG editor, in-place editing, streamlined content editing, the improved entity system, and more. The list of improvements is long!

My favorite part of Drupal 8 is that it will make building all types of Drupal sites — both big and small — much easier than with Drupal 7.

Key accomplishments in 2014 include:

Drupal 8 beta 1 released

October 1, 2014, amidst the fanfare at DrupalCon Amsterdam, we released Drupal 8 beta 1. This was an important milestone in the project, marking the finalization of major APIs, which enables contributed modules to begin porting in earnest.

Total number of Drupal 8 contributors surpasses 2,500

Our 2,500th core contributor was Tasya Rukmana (tadityar), a high-school student participating in Google Code-in 2014! Awesome.

Kick-starting contributed modules in Drupal 8

Drupal 8's new object-oriented API represents a significant paradigm shift for developers (there are many benefits to this). To help Drupal 7 pros make the jump to Drupal 8, Acquia funded the Drupal Module Upgrader project. This project will not only scan a Drupal 7 module and generate a report pointing off to the appropriate documentation on how to port it, there is even a mode that automatically re-writes much of your module's code to Drupal 8 to eliminate a huge chunk of the work.

Sprints, sprints and more sprints!

We organized dozens of sprints all around the world, and together hundreds of people came together in "real life" to help get Drupal 8 released. Sprints are a key part of momentum-building in Drupal, by laser-focusing on a specific goal, or by pairing both new and experienced contributors together for mentorship. Not only do sprints make solving tough issues easier, they also provide opportunities for building relationships and "leveling up" your skills.

Drupal 8 accelerate fund

Though it was launched just a month ago, the Drupal Association's Drupal 8 Accelerate Fund is already helping to add velocity to Drupal 8, by paying key contributors to help fix particularly onerous critical issues.

What is in store for 2015? Getting the Drupal 8 release done

Our current focus is resolving the Drupal 8 upgrade path issues, which will allow early adopters of Drupal 8 to upgrade their site data between beta releases, and should result in a further uptick to Drupal 8 development velocity.

Once we reach zero critical issues, we begin the release candidate phase. Among the areas left to polish up after the Drupal 8 upgrade path issues are bringing external libraries up to date, finalizing documentation, and performance.

Continuous improvements after Drupal 8

Unlike prior versions of Drupal, Drupal 8 has adopted a new release cycle that will provide backwards-compatible "feature" releases every 6 months. I'm extremely excited about this change, as it means we can innovate on the core platform for years to come after release, versus holding all of the new goodies until Drupal 9.

Getting more organizations to contribute

We're now one of the largest Open Source projects in terms of active contributors, if not the largest. That growth requires us to evolve how we work. Over the years, we've grown from a 100% volunteer-driven model to a model where there is a mix of volunteers, contributors who are partially funded by their customers or employers, and contributors who are paid full-time to work on Drupal.

While this shift has big benefits in making Drupal more sustainable, it also means there is increasingly more corporate participation and influence. One of our biggest challenges for 2015 is to figure out how we can get more commercial organizations to step up to take on more of the shared maintenance of Drupal, while at the same time respecting the needs and desires of our entire community.

Improving our governance model

There has also been a lot of talk about optimizing the way in which we work, to make it more explicit who is responsible for what, how decisions are made, and so on. This year I plan to work with others in the community to revamp Drupal core's governance model to bring more transparency and appoint additional leadership.

Conclusion

Overall, I'm thrilled with the progress that the Drupal core contributors have made in 2014, and want to extend an enormous thanks to each and every one of our 2,500 contributors who have brought us this far. I'm feeling very positive about our momentum going into 2015.

Drupal 8 will set a new standard for ease of use, power and flexibility, and will have something for everyone to love. Without a doubt, Drupal 8 will take our community to new heights. Let's do this!

YesCT: Making MidCamp more accessible

Making MidCamp more accessible

Even though it's still two months away, I know that MidCamp 2015 (March 19 - 22) is going to be special. The venue hosting MidCamp this year is the University of Illinois at Chicago. UIC is both my alma mater and present employer. Student Center East (where the training and conference sessions will take place) may be familiar grounds to me, but these days I am looking at it from the perspective of a visitor who is completely unfamiliar with its layout.

UIC Student Center East entrance from Polk and Halsted streetsVenue accessibility

Liz Henry's article Unlocking the Invisible Elevator identifies some of the ways in which conference organizers can be proactive about event accessibility:

Some information is great to have in advance. Maps and explanations of access paths work well. It helps if they’re in web-accessible formats, usable by screen readers, and downloadable. Some information has to be embedded in your conference venue. Signs should clearly mark the accessible paths. Maps are very helpful so that people can estimate distances; this is a big deal for those of us who are exhausted and in pain. Put maps next to your signs please!

In late November, I did a preliminary walkthrough of Student Center East. I meandered around the building, photographing the main entrance to Student Center East, the location, interiors and paths to elevators, escalators and stairways, major "landmarks" for points of reference, and the conference area hallways and rooms. It may sound a bit like I was casing the place, but I learned about traffic flow, congestion areas and different points of entry to each floor, whether by escalator and stairs or elevator.

Next, I contacted folks from UIC Office of Facility and Space Planning to obtain floor plans for each of the buildings and floors where MidCamp events are going to take place. They were quick to respond and the floor plans I got are very detailed. I annotated them, marking session rooms, elevators, restrooms and possible traffic flow. The annotations will serve as blueprint for locations of signs, as well as written directions that will be posted to the website.

Annotated floor plan of Student Center East ground floor, with photos of elevator #6 and escalator overlaid.

This week, MidCamp organizers and I plan to do another walkthrough at UIC. Together we hope to identify and address any accessibility and navigation pitfalls. Photos, annotated floor plans, and navigation information will be posted to the MidCamp website. We want to make sure that there is good information about the venue available ahead of time, as well as informative signs on the spot when you attend MidCamp.

Of course, floor plans and elevators are not the only aspect of conference accessibility. Childcare, real-time captioning, transcripts and captioning of session videos are some of the other ways in which events are made more accessible to diverse audiences. It's a direction that I hope MidCamp will follow.

Anonymized session selection

Another reason why I'm excited about is that MidCamp session submission is now open (it will close on Monday January 19). The session selection committee will pick from anonymized submissions for 20 and 50 minute talks. From the conference website:

  1. A volunteer who is NOT on the selection team will anonymize and remove gendered pronouns from abstracts/bios.
  2. The team will make a first round of selections from the anonymized submissions.
  3. A second round will then make sure we have not selected speakers multiple times (excluding panel participants).

By anonymizing session selection, we hope to give thorough consideration to everyone's proposals without biases ("oh, I know this speaker," or "I've never heard of this speaker"). Having a diverse lineup of speakers from all experience levels is important to us. A few weeks ago, Cathy Theys brainstormed a list of topics spanning social, technical, business, and other aspects of Drupal ecosystem that would be welcome at MidCamp. The list is long, but by no means exhaustive.

Are you on the fence about submitting a proposal? Take a look at the variety of suggestions for topics and fill out the submission form (the deadline is Monday, January 19). I want to see you at MidCamp!

Capgemini Engineering: Drupal 8 PSR-4 Form compatibility in Drupal 7

mer, 14/01/2015 - 01:00

Up until Drupal 8 there has been little to encourage well organised code. It now has PSR-4 autoloading so your classes are automatically included. Even though Drupal 8 is just round the corner, a lot of us will still be using Drupal 7 for quite a while, however that doesn’t mean we can’t benefit from this structure in Drupal 7.

This post covers two parts:

  1. Autoloading class files.
  2. Avoiding extra plumbing to hook into your class methods.

You’re probably familiar with drupal_get_form(‘my_example_form’) which then looks for a function my_example_form(). The issue is that your form definition will no longer be in such a function but within a method in a class. To cover both these parts we will be using two modules:

  1. XAutoLoad - Which will autoload our class.
  2. Cool - Which allows us to abstract the usual functions into class methods.

Drupal 8 was originally using PSR-0 which has been deprecated in favour of PSR-4. As a consequence the Cool module uses PSR-0 in its examples although it does support PSR-4. We will create an example module called psr4_form.

The information on autoloading and folder structure for PSR-4 in Drupal 8 states that we should place our form class in psr4_form/src/Form/FormExample.php however the cool module instead loads from a FormControllers folder: psr4_form/src/FormControllers/FormExample.php.

We can get round this by providing our own hook_forms() as laid out in the Cool module:

/** * Implements hook_forms(). */ function psr4_form_forms($form_id, $args) { $classes = \Drupal\cool\Loader::mapImplementationsAvailable('Form', '\Drupal\cool\Controllers\FormController'); unset($classes['Drupal\\cool\\BaseForm']); unset($classes['Drupal\\cool\\BaseSettingsForm']); $forms = array(); foreach ($classes as $class_name) { $forms[$class_name::getId()] = array( 'callback' => 'cool_default_form_callback', 'callback arguments' => array($class_name), ); } return $forms; }

If you are ok placing your class in the FormControllers folder then you can omit the above function to keep your .module file simple or you could put the hook in another module. Potentially the Cool module could be updated to reflect this.

This class requires a namespace of the form Drupal\<module_name>\Form. It also extends the BaseForm class provided by the Cool module so we don’t need to explicitly create our form functions:

namespace Drupal\psr4_form\Form; class FormExample extends \Drupal\cool\BaseForm { ... }

Within our FormExample class we need a method getId() to expose the form_id to Drupal:

public static function getId() { return 'psr4_form'; }

And of course we need the form builder:

public static function build() { $form = parent::build(); $form['my_textfield'] = array( '#type' => 'textfield', '#title' => t('My textfield'), ); return $form; }

All that is left is to define your validate and submit methods following the Drupal 8 form API.

At the time of writing, the Cool module isn’t up to date with Drupal 8 Form API conventions. I started this blog post with the intention of a direct copy and paste of the src folder. Unfortunately the methods don’t quite follow the exact same conventions and they also need to be static:

Drupal 7 Drupal 8 getId getFormId build buildForm validate validateForm submit submitForm

This example module can be found at https://github.com/oliverpolden/psr4_form.

Taking it further

Drupal 8 is just round the corner but a lot of us will still be using Drupal 7 for the foreseeable future. Taking this approach allows us to learn and make use of Drupal 8 conventions as well as making it easier to migrate from Drupal 7. It would be nice to see the Cool module be brought up to date with the current API, perhaps something I will be helping with in the not so distant future.

Drupal Watchdog: MySQL Query Optimization

mar, 13/01/2015 - 18:52
Feature

A large part of MySQL optimization lies in improving poorly performing SQL queries. While tuning is important, it often has nowhere near the impact of actually fixing a poorly performing query. Fixing queries is also a lot more fun. Obviously query optimization is a large subject, and can’t possibly be covered in full in a single article. I highly recommend that you get a book on this subject; for any Drupal developer, it is well worth learning.

As a web developer using a CMS, you are only slightly removed from the SQL layer. Not completely knowing how to use this layer and how to optimize it is very limiting. To get you started, we will cover some very basic optimization, index usage, and join optimization techniques.

Index Basics

Even though indexes are very important for database performance, they are not completely understood by many developers, which often leads to easily-avoidable problems. The main issue is the mystical belief that the MySQL optimizer should be able to quickly run a query if an index so much as touches the columns in question. Sadly, indexes are not magical.

It is best to think of an index as a tree, largely because they are trees in most DB systems. (B+Trees, specifically; for more information, see http://wdog.it/4/1/btree.)

Thus, if you have an example index test that covers (columnA, columnB), you literally have a tree of columnA values, with columnB values in the leaves. If you have a query that has a WHERE condition on these two columns, MySQL will go through this tree looking for the correct columnA value first, and then go into the leaves of that object, and find the correct columnB value.

When you have some experience with Drupal it will be clear that you can set your rights for content management in the permission table (/admin/people/permissions).

Check the appropriate permissions and everyone will get the required rights to view, add, edit or delete content. In other words the so-called CRUD actions: Create, Read, Update, Delete.

So far so good.

ERPAL: Looking back on 2014 with Drupal business apps

mar, 13/01/2015 - 16:30

The year 2014 was entirely about flexible and open business applications based on Drupal - and we’ll continue to follow this vision in 2015.
In 2014 we staffed up our ERPAL team and won strategic clients who gave us feedback and helped us continue to finance our open source development. This positive resonance provides confirmation that Drupal can become an ever-larger part of the open source business application market.
One of the ERPAL Platform projects of 2014 that we’re very proud of was presented in a featured webinar on open integration with Drupal commerce. The ERPAL Platform based foam creator gives an industrial company the means to let its clients construct and order individually manufactured products – all directly online. The orders are sent to the manufacturing department and production starts. Because the application is fully integrated with the company’s workflow and IT infrastructure, no manual data transfer is needed and the efficiency of the whole sales-to-production process has increased by more than 75%. This unique use case shows the power of Drupal extended well beyond content sites.

Whereas other open source business apps like Odoo focus solely on broadening the palette of business apps available for ERP systems, ERPAL comes from the other direction. We use Drupal as a highly flexible and stable application framework that helps you build any kind of web application at all - and Drupal can do this with almost no coding, just by configuring. Using this strategy we introduced Drupal to some businesses that hadn’t even heard of Drupal. And now that they see its power and flexibility, they wouldn’t want to go without it anymore.
With ERPAL Platform, which we released in 2014, we provide Drupal developers and site builders with a free Drupal distribution for building highly flexible business applications and e-commerce businesses in a Drupal box. It integrates many Drupal modules like Drupal Commerce and Rules, which are known to leverage flexibility. With the help of the Drupal community we implemented an architecture that covers contact management and all components of the sales process such as quotes, orders and invoices. As Drupal became more open, providing web service for all entities in Drupal 8, we implemented the architecture of ERPAL to integrate with other services. Together with a closed beta customer test pool, we are running ERPAL Platform as a fully-integrated agency platform, automating integration tasks between Jira, Mite, Trello, Redmine and toggle. It helps save time in administration and automates billing and controlling processes in project-based business. Thanks to everyone who joined our ERPAL Platform integration survey. This survey is still open and we are looking forward to even more feedback to help us increase our number of beta testers.

Because in 2014 we were deploying more than 25 Drupal-based business apps and always had Drupalgeddon in mind, we decided to go public with our technology for Drupal update automation, which we previously had used only internally for our clients. Drop Guard lets Drupal users and agencies automate Drupal security updates immediately after a new security update release. If you’re interested in further details, workflows and technology, read more in our blog post about how since 2012 we’ve automated Drupal security updates with ERPAL: you can too!

All in all, 2014 was an amazing year for ERPAL and we saw that there’s a market for open source business applications. We’re looking forward to contributing even more code, know-how, webinars and sessions to the Drupal community in 2015.

Drupalize.Me: Changes in the Form API in Drupal 8

mar, 13/01/2015 - 15:13

In my previous post, I documented the first of my Adventures in Porting a D7 Form Module to Drupal 8. In that article, I documented how I used the Drupal Module Upgrader to convert my Drupal 7 module, Form Fun, to Drupal 8 and what I learned along the way about how Routes and Controllers replaced hook_menu, and what I gleaned from change records about other API changes. This article is a continuation of that post, so you might want to pop over and give it a read so that you're up to speed with what we're doing here.
