Drupal version: 9.3.13
Basically, I'm trying to understand how using a contrib module's translation works. I want to be able to download and use the translations from the Drupal infrastructure, and can't seem to get this to work.
I have a site with two languages, English and German (Default). I did run "drush locale-check" and "drush locale-update", and that imported the German core language file (which now is saved at "web/sites/default/files/translations/drupal-9.3.13.de.po"). If the current interface language is German, I do see all kinds of core features translated to German.
- Configuration Translation
- Interface Translation
I then installed a module, first loading it via composer and then installing it via the "admin/modules" page. I made sure that a string of the module was used in a page, that this string is translated on localize.drupal.org for the current version of the module and that it showed up under "admin/config/regional/translate" as untranslated afterwards. Then I ran both the translation commands again. The output says, that translations for one project were checked and that nothing was changed. No translation showed up for my test string.
I just tested this on a fresh Drupal installation with the "drupal/cookies" module (version 1.0.18, https://www.drupal.org/project/cookies). The module's page on localize.drupal.org shows lots of translated Strings: https://localize.drupal.org/translate/languages/de/translate?project=cookies&status=2&release=531668&search=&author&context=all&limit=10&sid=0
What I am aware of:
- My own custom modules use .po files, and those are loaded just fine.
- There seems to be a bug that causes new versions of modules not being picked up (https://www.drupal.org/project/drupal/issues/2575945). That is also bad, but here no translation for the module is loaded in the first place.
I tried to debug this and got as far as checking "locale.project" and "locale.translation_status" from the "key_value" table. Both only contain Drupal core on my test site. In the production site, all the custom modules are also contained, but none of the contributed modules.
So the question is: What am I missing here? How is this supposed to work?
