D8 Twig cheat sheet

Conditionals

To check if a field has a value, check to see if the 0 array item is populated. Simply checking if content.field_name is truthy will not work since that variable will be defined even if the field is empty.

{% if content.field_name.0 %}
  {{ field_name }}
{% endif %}

Drupal 9 CMS: Delete equal customized translation (source language string = target language string)

If you should encounter the problem that some translations are wrongly translated with the equal source language string (for example in our case there were German translations for "Author" translated with "Author" or "Published" with "Published"), you may use the following snippet to list them.

SELECT s.lid,s.source, t.translation FROM `locales_source` s
INNER JOIN locales_target t
WHERE s.lid=t.lid AND CONVERT(s.source USING utf8) = CONVERT(t.translation USING utf8) 
AND t.customized=1

To finally delete them, you may use something like this, but make a backup before and know what you're doing!

We use all of our CSS and it’s pretty small overall. When I delete a template, I know the exact corresponding CSS file and I can delete it all at once. Nothing gets left behind.”

You often hear updog saying stuff like this. Who’s updog? Not much, who is up with you?

This is where any fun you might have been having ends. Now it’s time to get serious and talk about rules.

Writing CSS is hard. Even if you know all the intricacies of position and float and overflow and z-index, it’s easy to end up with spaghetti code where you need inline styles, !important rules, unused cruft, and general confusion. This guide provides some architecture for writing CSS so it stays clean and ma
