I've got a module which contains a config/optional folder which has the content:


These files have been exported from an existing installation without uuid's. When I enable the module, the config does not import since the module paragraphs has not yet been enabled. When I enable paragraphs the paragraph type my_paragraph_id is created as expected. The field storage for field_my_field is also created, since I can create a new field based on the existing field field_my_field. Though, the field is not created on the paragraph itself.

I've tried moving the config files to config/install and then it simply works as expected; the field gets created on the paragraph just fine. But the module paragraph should be optional and only then the config should be created, therefor, I want it to be optional.

Why does the config/optional not install the field?


Optional config is only installed if it has an explicit dependency on a module that is being installed right now. Otherwise that configuration would be re-installed every time you install a module, even if it is something you chose to delete on a specific site.

The downside of that is that there are some grey areas of config that depends on config that depends on a module being installed that isn't found by this. Although that should also work but apparently does not in this case.

As a workaround, you can add an enforced dependency on the paragraphs module on those configurations that aren't being imported, then it should work. See https://www.drupal.org/node/2404447

  • I knew about enforced, but I figured that that only made sure that dependencies in that property were made persistent and not auto-calculated. I did not know that it would have impact on optional config and the import of that on install. Thanks! It works now!
