For some reason I don't see the views theme suggestions in my twig debug information? What do I miss?

  • In my development.services.yml in set debug to true.
  • I do see debug information and theme suggestions from other page items.
  • I do see views debug info but not the theme suggestions. See image below:

On other website I see suggestions like this:

This is a bug in Drupal 8 core, currently being worked on in several different core issues, many of which have working patches.

If you need the functionality now, you have two options:

  1. Try the patches from comment #22 (or more recent) on Issue #2923634 and the patches on Issue #2752443. Read the comment thread on #2923634 to get a full understanding of what's going on here.

  2. Or use the well-vetted patch from comment #139 on Issue #2118743 which has been postponed in favor of option 1 above.

I'm using the patch from option 2 (#2118743) successfully. Please note that this does go against the standard core contributor recommendations. But the reason is because #2118743 has a single, well-vetted and working patch for something that is only enabled / used during development, and instead of needing to test out various combinations of two separate patches that are still under development. Once the better solution (#2923634 and #2752443) get fixed in core, #2118743 should be obviated and no longer required.

  • Yay. Its December 2020, and after being postponed for 3+ years, the community has come back around to its senses :P and has started pushing forward on #2118743 again.

You can see that you get views-view-fields.html.twig for example, the naming conventions is then:

  • views-view-fields--foobar--page.html.twig
  • views-view-fields--page.html.twig
  • views-view-fields--foobar.html.twig
  • views-view-fields.html.twig

From: https://api.drupal.org/api/drupal/core%21modules%21views%21views.theme.inc/group/views_templates/8.2.x

In case you have a custom news feed it would look like this:

views-view-fields--news-feed.html.twig

where news-feed is the machine name of the view.

You can copy the default templates in the stable theme in core to have something to start building from.

  • Yes, that I know but I'm used to get more suggestions, see edited question for an extra image of what this looks like.

  • Interesting, I see now. Well I did a small test and when I removed my custom template, the suggestions also got removed and when I put the template back I got the suggestions back. Not sure if this is a bug in Drupal but it might explain your problem.

  • Hhhmm, strange, I'm working with a custom template. Any suggestions how to fix this?

  • Do you get the custom template to show? If not, something with the naming is not corresponding to the template name convention. If you get it to show I don't know why you don't get name suggestions.
