Localising dates in twig templates

14th Aug 2018

A client noticed the dates on their news articles were not being translated into the correct language. The name of the month would always appear in English, even though all the month names had themselves been translated and showed correctly elsewhere. The problem turned out to be down to the twig filter being used in the template to format the date. This is what we did have:

{% set newsDate = node.getCreatedTime|date('j F Y') %}
{% trans %} {{ newsDate }}{% endtrans %}

So this would produce something like '1 March 2018' instead of '1 März 2018' when in German....

Keeping dynamic HTML classes easy to find

The Problem

I imagine many of us have been there: there’s some CSS class in your markup, and you need to do something with it. Maybe you want to remove it, change it, or perhaps alter its style declarations. “Easy peasy,” you think, “I’m a developer. I got this.” And so you should.

Next, if you’re anything like me, your first instinct is to fire up your search tool of choice and search your codebase for that string. You’d expect that would lead you to where that class is getting added to your markup, along with anywhere CSS rules...

Including form values in an email

26th Jun 2018

Let's say you've built a custom form for your Drupal 8 site. It contains various elements for input (name, email address, a message, that kind of thing), and you want to send the submitted values in an email to someone (perhaps a site admin). That's a pretty common thing to need to do.

This could be done with Drupal's core contact forms, webforms, or similar -- but there are cases when a bespoke form is needed, for example, to allow some special business logic to be applied to its input or the form presentation. The drawback of a custom form...

Rebranding ComputerMinds - Part 6: Migration

I volunteered to carry out the migration for the new ComputerMinds site as migration was one of the very few areas of Drupal that I hadn’t delved into thus far. With Drupal 8 becoming more and more popular, now was a great opportunity to learn the migration ropes. Luckily, Drupal 8’s migration has greatly improved since Drupal 7 so my life was made somewhat a little “easier”!

This article will be aimed at some of my finds and processes, rather than a “How to do a D8 migration”.

Since our new site was very different to our old one in...

Rebranding ComputerMinds - Part 5: Development

1st Jun 2018

Let's have a quick look through our development process on this project and pick out some of the more interesting bits. As briefly mentioned in the last article we are using a composer set up and all code is version controlled using git on github. All pretty standard stuff.

Frontend

In the previous article I briefly discussed how we set up Pattern Lab. Before getting stuck in to the components that would make up the pages of the site, we first needed to set up some global variables and grid. Variables allow us to reuse common values throughout the SCSS and...

GDPR compliance steps for Drupal Developers

30th May 2018

The new GDPR laws are here, hurrah!

Having a number of developers handling databases from a number of client sites could easily be a nightmare, but we at ComputerMinds spent quite some time thinking about how to get and keep everybody safe and squeaky clean on the personal data front.

Here's a quick run-down of the key things to be aware of - and a pretty poster to help you keep it all in mind :)

Remove personal data from your system

  1. Review all databases on your computer, making sure to consider also those .sql dump files still sat in your downloads directory...

Got a config schema error on saving a view?

14th May 2018

We ran into an obscure error recently, when saving a view that used a custom views plugin. It was supposed to be a very simple extension to core's bundle (content type) filter:

InvalidArgumentException: The configuration property display.default.display_options.filters.bundle.value.article doesn't exist. in Drupal\Core\Config\Schema\ArrayElement->get() (line 76 of [...]/core/lib/Drupal/Core/Config/Schema/ArrayElement.php).

Several contrib projects ran into this issue too: Drupal Commerce, Search API and Webform Views integration. There's even a core issue that looked relevant... but it turned out to be a simple, if perhaps surprising fix. If you ever run into it, it will have a different property (i.e. due to whichever plugin...

Creating multilingual variables

A super quick blast from the past today; a Drupal 7 based article!

I had some work recently to create a new "setting" variable for one our Drupal 7 multilingual sites, which meant creating multilingual versions of those variables. I soon found out that there is very much a correct way - or order - to achieve this as I got this one very wrong (I had to re-instate my DB!). So here I am writing a very quick guide to help those from my wrong doings.

(This guide assumes you have a multilingual site setup with i18n's Variable translation...

Rebranding ComputerMinds - Part 4: Pattern Lab

3rd May 2018

We didn’t see this project solely as a chance to rebrand and rebuild for ourselves, it was also an opportunity to try something new and expand our collective knowledge with the potential for using with clients in the future. We had been discussing using Pattern Lab for Front End development for some time and this was the perfect opportunity to try it out.

Patten Lab allows the creation of component-driven user interfaces using atomic design principles. This means we can create modular patterns all packaged up nicely that can be assembled together to build a site. Plus we can use...

Rendering Drupal 8 fields (the right way)

10th Apr 2018

Once upon a time, we wrote an article about how to render fields on their own in Drupal 7, which was really handy because Drupal 7 wasn't always intuitive. It's common to want to display a field outside of the context of its main entity page, like showing author information in a sidebar block or in a panel, but you had to just know which functions to use. Drupal 8 has come along since then using 'grown up' things like objects and methods, which actually makes the job a little easier. So now we have this:

The short answer
