Re-save all nodes of a particular type in an update hook in Drupal 8

I recently needed to re-save all the nodes of a particular content type (after I had added some fields and default configuration) as part of a Drupal 8 site update and deployment. I could go in after deploying the new code and configuration, and manually re-save all content using the built-in bulk operation available on the /admin/content page, but that would not be ideal, because there would be a period of time where the content isn't updated on the live site—plus, manual processes are fragile and prone to failure, so I avoid them at all costs.

In my Drupal 8 module, called custom, I added the following update hook, inside custom.install:

Can't upload more than 20 files using Media Image Entities in Drupal 8?

After migrating an older Drupal 6 site with 20,000 media items to Drupal 8, I found a strange problem with image uploads. On the Drupal site, using Image FUpload and Adobe Flash, I could upload up to 99 images in one go. On the new Drupal 8 site, I was only able to upload 20 images, even though I didn't see an error message or any other indication that the rest of the images I had selected through the Media Image upload form were not successfully added.

I could choose 21, 40, or 500 images, but only 20 were ever added to an album at any time.

There were no apparent warnings on the screen, so I just assumed there was some random bug in the Media Image Entity or Media module suite that limited uploads to 20 files at a time.

But due to an unrelated error, I glanced at the PHP logs one day, and noticed the following error message:

Testing redirections using Behat and the Behat Drupal Extension

One project I'm working on needed a Behat test added to test whether a particular redirection works properly. Basically, I wanted to test for the following:

  1. An anonymous user accesses a file at a URL like http://www.example.com/pictures/test.jpg
  2. The anonymous user is redirected to the path http://www.example.com/sites/default/files/pictures/test.jpg

Since the site uses Apache, I added the actual redirect to the site's .htaccess file in the docroot, using the following Rewrite configuration:

<IfModule mod_rewrite.c>
  RewriteEngine on

  # Rewrite requests for /profile_images to public files directory location.
  RewriteRule ^ pictures/(.*)$ /sites/default/files/pictures/$1 [L,NC,R=301]
</IfModule>

Testing with curl --head, I could see that the proper headers were set—Location was set to the correct redirected URL, and the response gave a 301. So now I had to add the Behat test.

Drupal VM Tips & Tricks - brief remote presentation for DrupalDC

Yesterday I presented Drupal VM Tips & Tricks at the DrupalDC meetup, remotely. I didn't have a lot of time to prepare anything for the presentation, but I thought it would be valuable to walk through some of the neat features of Drupal VM people might not know about.

Here's the video from the presentation:

Some relevant links mentioned during the presentation:

Add a set of Taxonomy terms via a custom Drupal module's update hook

From time to time, I've needed to have a default set of Taxonomy terms created at the same time as a content type, as in the case of a field with a required Taxonomy term reference, using a Taxonomy that is not 'free tag' style.

Instead of requiring someone to go in and manually add all the terms after code is deployed, you can add terms in a custom module's update hook, like so:

Thoughts on the Acquia Certified Drupal 8 Site Builder Exam

Another year, another Acquia Certification exam... (wait—I think I've said that before).

Acquia Certified Drupal Site Builder - Drupal 8 2016

The latest of the updated Acquia Certification Exams is the Acquia Certified Drupal 8 Site Builder. It's meant for the average Drupal site builder to test and evaluate familiarity with building websites using Drupal 8, and it's the same as all the previous exams in style: a series of 40 questions posed in the conversational manner, with answers you would provide if you were telling a project manager or site owner how you would implement a feature.

Setting up Faceted Apache Solr search in Drupal 8

Note: Extra special thanks to Doug Vann for providing motivation to finally post this blog post!

Early in 2016, when the Search API and Solr-related modules for Drupal 8 were in early alpha status, I wrote the blog post Set up a faceted Apache Solr search page on Drupal 8 with Search API Solr and Facets.

Upgrading Drupal VM in a BLT-powered project

Limiting the amount of surprises you get when developing a large-scale Drupal project is always a good thing. And to that end, Acquia's BLT (Build and Launch Tools) wisely chooses to leave Drupal VM alone when updating BLT itself. Updates to Drupal VM can and should be done independently of install profile and development and deployment tooling.

composer require geerlingguy/drupal-vm:~4.0

But this creates a conundrum: how do you upgrade Drupal VM within a project that uses BLT and has Drupal VM as one of it's composer dependencies? It's actually quite simple—and since I just did it for one of my projects, I thought I'd document the process here for future reference:

Migrating 20,000 images, audio clips, and video clips into Drupal 8

tl;dr: If you want to skip the 'how-to' part and explanation, check out the pix_migrate example Drupal 8 migration module on GitHub.

For a couple years, I wanted to work on my first personal site migration into Drupal 8, for the last Drupal 6 site I had running on my servers. I've run a family photo/audio/video sharing website since 2009, and through the years it has accumulated hundreds of galleries, and over 20,000 media items.
