ThinkShout: Upgrading MailChimp eCommerce and an Introduction to Drupal 8's Event System

Thu, 2017-07-06 09:00

If you’ve ever built a Drupal 7 module, then you’ll be familiar with hooks: functions that allow modules to react to things happening in other modules. The hook system is functionally fine but, with so many hooks to implement, .module files often become bloated and difficult to manage.

Drupal 8’s event system does a lot to reduce the clutter of hooks. Now, instead of using a hook, you can create an event subscriber that will execute your code every time a module triggers an event. This is similar to the hook system only in the effect; the execution is very different.

Porting our popular MailChimp eCommerce module to Drupal 8 gave me the perfect opportunity learn about the event system. I use the word “opportunity” to disguise the fact that I was forced to learn how events work because it was impossible to port the module without doing so.

The MailChimp eCommerce module depends on the Commerce module, naturally, and in Drupal 8, the Commerce module makes heavy use of events.

First, let’s look at an event. I’m using an example ripped straight from Commerce.

The Commerce submodule, Commerce Cart, contains a class named CartEntityAddEvent. You can find it here.

The class itself is simple; it’s designed to store a few values - the cart, the item being added to the cart, and the quantity of that item. The class also has a few getter functions for convenience.

Most importantly, this class represents an event that’s triggered every time a user adds an item to their shopping cart. This is done using just two lines of code:

$event = new CartEntityAddEvent($cart, $purchased_entity, $quantity, $saved_order_item); $this->eventDispatcher->dispatch(CartEvents::CART_ENTITY_ADD, $event);

The event class is created with all the relevant values, then “dispatched” to any event subscribers configured to pay attention to it. When dispatched, the event is identified by a constant - CartEvents::CART_ENTITY_ADD. This constant is used by event subscribers, which we’ll take a look at now.

This is a cut-down version of an event subscriber used by our world famous MailChimp eCommerce module.

/** * Event Subscriber for Commerce Carts. */ class CartEventSubscriber implements EventSubscriberInterface { /** * The Cart Handler. * * @var \Drupal\mailchimp_ecommerce\CartHandler */ private $cart_handler; /** * The Order Handler. * * @var \Drupal\mailchimp_ecommerce\OrderHandler */ private $order_handler; /** * CartEventSubscriber constructor. * * @param \Drupal\mailchimp_ecommerce\CartHandler $cart_handler * The Cart Handler. * @param \Drupal\mailchimp_ecommerce\OrderHandler $order_handler * The Order Handler. */ public function __construct(CartHandler $cart_handler, OrderHandler $order_handler) { $this->cart_handler = $cart_handler; $this->order_handler = $order_handler; } /** * Respond to event fired after adding a cart item. */ public function cartAdd(CartEntityAddEvent $event) { /** @var \Drupal\commerce_order\Entity\Order $order */ $order = $event->getCart(); /** @var \Drupal\commerce_order\Entity\OrderItem $order_item */ $order_item = $event->getOrderItem(); $product = $this->order_handler->buildProduct($order_item); $this->cart_handler->addCartLine($order->id(), $order_item->id(), $product); } /** * {@inheritdoc} */ public static function getSubscribedEvents() { $events[CartEvents::CART_ENTITY_ADD][] = ['cartAdd']; return $events; } }

Here’s the complete version, if you’re interested.

So what does it do, exactly?

Let’s start with the getSubscribedEvents() function. This is where we define which events we want to subscribe to, and assign each event a processing function. Here we are subscribing to just one event, the “cart entity add” event, and assigning the cartAdd() function as a processor.

Note that the cartAdd() function takes one argument, an instance of the CartEntityAddEvent class. That’s the same class we looked at earlier - the event class defined in the Commerce Cart module. This is where our module reacts to that event being triggered.

The cartAdd() function itself extracts the order and item information from the event and uses an instance of the CartHandler class, provided by the MailChimp eCommerce module, to send updated cart information to MailChimp’s API.

One final thing:

Event subscribers won’t work unless they are defined as a service. Services are defined in a module’s *.services.yml file, which you can learn more about here.

The service definition for the CartEventSubscriber looks like this:

mailchimp_ecommerce_commerce.cart_event_subscriber: class: '\Drupal\mailchimp_ecommerce_commerce\EventSubscriber\CartEventSubscriber' arguments: ['@mailchimp_ecommerce.cart_handler', '@mailchimp_ecommerce.order_handler'] tags: - { name: event_subscriber }

We identify the class using its namespace, inject the “cart_handler” and “order_handler” services, then, finally, tag the service as an “event_subscriber”. Check out the full file here. Just for completeness, the two injected services are defined in here.

I’m a big fan of how Drupal 8 has shifted towards a more object-oriented way of doing things. It’s more organized, promotes consistency between modules, and, best of all, finally signals an end to massive .module files.

Zivtech: Drupal vs. WordPress for Higher Education Websites

Thu, 2017-07-06 07:32

You’re about to begin a huge overhaul of your higher education website and one of the first steps is choosing a content management system. It’s likely that Drupal and WordPress have come up in your research, and you may be trying to decide between the two.

Drupal and WordPress are often compared to one another because they’re both open source content management systems. Both are capable of creating clean, responsive websites that are easy to manage for content editors. The functionality of both can be extended using third party code. And the code for both is openly available for anyone to use, change, and distribute, meaning there are no licensing fees like those required by closed source options. 

There are a significant number of higher education websites on Drupal; Harvard, Brown, and Oxford University all use the CMS, to name a few. According to Drupal.org, 71% of the top 100 universities use Drupal. And there’s some sound reasoning behind that.

Both WordPress and Drupal have strengths and are well suited for a diverse range of projects. WordPress was primarily built for standalone websites or blogs with minimal variation in content types. Drupal was built for more complex, feature rich websites that require significant interconnectivity between pages or site sections, like those required by higher education. 

Here are some factors to consider when choosing between the two content management systems.

Flocon de toile | Freelance Drupal: The 13 mythical (or not) defects of Drupal 8

Thu, 2017-07-06 03:00
Having had the opportunity to read a recent comparative study between Drupal 8 and SPIP, I discovered a Drupal perception that is not mine. Far be it from me to want to compare Drupal and SPIP. Indeed, I know very badly SPIP, at least only as a basic user, and much less than Drupal, and so I will not venture on such a comparison. Also, I wanted to share these mythical, real or perceived defects of Drupal 8, which I recently discovered and which I think deserve a counterpoint.

Dropsolid: Drupal 8 on Google Cloud with Kubernetes

Wed, 2017-07-05 23:53
06 Jul Deploying Drupal 8 onto Google Cloud using Kubernetes Nick Veenhof

A month ago I received the honour to present at DrupalJam 2017. What a wonderful event! I had been invited to talk about deploying Drupal 8 onto kubernetes, which can be found as a hosted service in Google Cloud.

Our move to Google

Recently, we made the decision at Dropsolid to move from regular virtual machine instances in Gandi towards instances and services in Google Cloud, as we believe that the capabilities of such a cloud provider offer possibilities that are unprecedented. GC is not only offering affordable virtual machines (instances) but also affordable and competitive offerings regarding hosted MySQL. But that’s not all... Since we like our R&D environment and are looking for achieving greater and bigger goals, it is in our interest to see that Google is publishing new AI and data-analysis APIs at a pace that we don’t see anywhere else.

In practice

So... Back to the technicalities. I wanted to run an experiment on how I could run Drupal on an infrastructure that did not need any humans behind the wheel, nor any maintenance. I found this in the way of three components:

An overview of Kubernetes and the setup can be seen in the following video:

 One component that I found to be missing, was a shared filesystem between the two ‘Pods’ (Containers). Drupal relies on user files or images and these should be stored somewhere. We do not want to alter the behaviour of Drupal or get into the application itself, as that introduces risk. Not all the websites that we would like to host, are modifiable.

  • We could map the folder to an AWS S3 bucket or Google Cloud Storage bucket, but that would be too slow for our needs. What we actually wanted is a competitor of AWS EFS, but unfortunately Google Cloud did not have this available.
  • We can work our way around it by setting up a NFS server or Gluster server in kubernetes, but that drives us away from our initial goal - less maintenance, so we can focus on building awesome experiences, which is the Drupal application.

If you are interested how I did the setup of the NFS, the slides go into deep detail how to set up this NFS cluster. The code is also available at https://github.com/nickveenhof/drupal-docker-with-volume

I recorded a video how this deployment works. Caution, I did speed it up quite a bit.

Key findings

Now, what is the key take-away from all this? That I moved the particular website back to regular hosting, eg a shared space with a human behind the wheels here at Dropsolid. The reason was that for a single site, the cost outweigh the benefits and even though it is claimed to be fault-tolerant, I had numerous occasions where my pod did not want to recover, since the ‘failed’ one refused to be deleted. This ate up precious CPU space - on a server that barely had enough CPU. This can be solved with throwing more money at it, but that was not the intent.

I also discovered that constraining a pod to a fixed amount of CPU is not very useful when sharing a single server between multiple Drupal sites. Websites can have variable load and for small to medium sites with little traffic it is hard to justify the cost of pre-allocating those resources. I am curious to explore and test the Vertical Pod Autoscaling once they are finished, as this could certainly help applications with burstable workloads.

Having said that, I did learn a lot about what the future could hold. Going towards a system like this gets us really close to the 12-factor app ideology and I am completely in favour of a future like that.


Comments, questions? I'm curious to find out your take on this. Let me know in the comments box below or reach out directly on Twitter via @Nick_vh

Amazee Labs: Make your plans for DrupalCon Vienna

Wed, 2017-07-05 23:47
Make your plans for DrupalCon Vienna

DrupalCon Vienna is approaching quickly and if you haven’t done so far, it’s a good time to book your travels and accommodation. Even for an insider it is hard to keep track of everything that is going on, so in this post I would like to share an overview of what’s planned so far to keep in mind when planning your stay in Vienna.

Josef Dabernig Thu, 07/06/2017 - 08:47

Until Sunday, 24 September - Cyclists will be gathering again on the way to DrupalCon as part of Tour de Drupa Vienna. The Danube river allows for scenic flat rides from the west (Germany - Linz - Krems - Tulln - Vienna) or east (Budapest - Bratislava - Vienna). On Sunday 11am we will be meeting at the webshapers office in Tulln and in the afternoon cycle the last 40 kilometres together along the Donau to reach the Riesenrad in Vienna at 6pm. Join the conversation on g.d.o to get all the details.

Tour de Drupal Amsterdam 2014 from SchnitzelCopter on Vimeo.

Monday, 25 September - Drupal Austria together with the global Drupal Community are organizing summits and trainings. Those who have been to the DrupalCamps in 2013 or 2015 will remember FH Technikum Wien being supporter and host of these community organized activities. In terms of summits, we are planning for a great variety: Community Summit, Publishing Summit, Business Summit, Open Social Summit.

On the trainings side we are currently planning for a Docker workshop and a Drupal 8 module development course. Finally, there will be room for sprints thanks to sponsorship from Acquia and a CXO Dinner in the evening. Here’s some more information about the Monday program.

Tuesday, 26 September - The day kicks off the official DrupalCon program with the keynote by Dries Buytaert, Drupal Project Founder and will start 3 days of sessions, BoFs and social events. In the evening there will be the Open Minds Award (a regional open source award) and a ball celebrating Open Source as the official community party.

Wednesday, 27 September - Together with the keynote, other sessions and BoFs, there will also be the Drupal Association Public Board Meeting as well as the Women in Drupal social event and a CEO Dinner.

Thursday, 28 September - So far confirmed is that there will be Drupal Trivia Night. More details to follow as soon as it’s available.

Friday, 29 September - This is the last day of the conference and it’s all about Sprints: Join the community to learn how you can contribute to Drupal.

This sums up the main activities planned so far for DrupalCon Vienna. Alongside of the official important dates, hopefully this helps you to plan and organise your visit. Speaking from my own experience, DrupalCon with thousands of community members attending is a very special event: basically a week full of events. The above is only what we are aware of so far, you can be sure that various other individual events will be organized along the way.

Apart from the conference, Vienna has a lot to offer. If your schedule permits, I would definitely recommend adding a few days to explore the city. Some suggestions and ideas can be found on the official DrupalCon Vienna travels page. See you in Vienna.

Boby Aloysius Johnson | GSoC Blog: The evaluation week -- week 5

Wed, 2017-07-05 21:39
The evaluation week -- week 5 boaloysius Thu, 07/06/2017 - 00:39


The first phase evaluation of GSoC'17 is over. I had been working on integrating Google Cloud ML Engine to Drupal. Till now we have worked on creating a demo with Census example to illustrate that we can make predictions for our data in Drupal with ml-engine. Please check my first evaluation blog for details. After the evaluation, we worked on integrating standard pre-trained Tensorflow models to Drupal.

Pre-trained models are machine learning models trained on some dataset. As data is the key to classification accuracy, most of the standard pre-trained models available are trained on huge datasets. Our primary source of research was tensorflow/models. This repo had around 30 models but most of them needed training. In my inquiry, we found that Tensorflow lacks a gallery of trained models. Let me provide the link to some of the pre-trained models found. 


 Name  link   study  Inception  gz file Inception is an image recognition model trained on imageNet (a hierarchical classification of millions of images). It classifies the image into thousands of classes. Users have to do transfer learning to get their custom classes.  VGG  tar.gz file VGG(Visual Geometric Group) is a deep CNN developed by Oxford for image classification based on ImageNet. It is a model similar to inception. https://www.quora.com/What-is-the-VGG-neural-network   Syntaxnet 


Syntaxnet identifies the grammatical structure of the sentence. Please check these two blogs (blog1 and hblog2) for details.  Facenet



 This model uses CNN for face recognition. It can be used to recognize human faces (detect if two faces are the same). It is trained on two data sets, MS-Celeb-1M and CASIA-WebFace. Please check this report for details.


Finding lack of good pre-trained Tensorflow models is a serious drawback. Most of the natural language models we found needs training. For example, Syntaxnet is a highly accurate language parser. But we need to train on top of this to create a custom model for text summarizer and models useful for the end users. We don't have many ready-to-use natural language models suitable for Drupal.

To use standard models for our project, we have to do transfer learning. It is learning on top of what is already learned. In the Tensorflow for poets example, we remove the last softmax classification layer and train a layer on our own, for custom classification. Please refer to this in-depth video on how to create a custom image classifier. 

The major challenge we face is to create an abstraction to transfer data, train model, and to do the prediction for a variety of data types. We have to give the user flexibility to use any type of data (image, nominal, ordinal, numeric, ...) for training and prediction with ml-engine. For that, we have to create an abstraction that handles all data types. In the coming week, we will be exploring on how to create this abstraction.

Thank you

Valuebound: Things to know about Drupal 7’s Database API

Wed, 2017-07-05 18:22

The new drupal database API (known as DB:TNG) is built atop PHP's native PDO engine. The main objective behind Drupal’s database API is to allow developers to write one query that will work across different types of databases. So instead of writing specific queries for MSSQL, PostgreSQL, MongoDB, you can write one query. Then, a plugin is written to translate that query into native style and write the query in the initial language which is Database Abstraction layer. 
What are the new changes in Drupal 7’s new database API?
One of the biggest changes is Drupal 7's new database API, an object-oriented system which change  the way most developers will build…

GSoC17 : Client Side File Encryption : Week 5

This blog post summarises my fifth week of working with Google Summer of Code 2017 with Drupal.

Sandbox to implement the file encryption

This week I created a sandbox page in the router to test standalone file encryption. It utilised the HTML5 FileReading API to get the contents of the selected file that needs to be encrypted.

var reader = new FileReader();

An alternative would be:

var reader = new FileReaderSync();
