[META] Overview of Facets + Ajax issues

Until we model Facets as Views exposed filters, Facets and Views always have an impedance mismatch.

Yeah, facets with ajax were a mistake - I shouldn't have committed that patch without adding a ton of extra tests and fixed the results.

We can't model them as exposed filters because we don't support just views (see search api page or basically anything that is a Search API display).

fwiw, I created #3073444: Create views plugins to render facets and summaries in filters and areas - I understand the need for support for ajax since it's not only views, although, in a way, I would argue that having it only work within views would be fine imo. You wouldn't have to care about all the weird things happening in ajax since views does all the heavy lifting. Let me know if you would still be up for that exposed filter. Afaics, it will only be PHP code anyway.

Of course, since it's in, you're kind of stuck with it now - unless it's only dev, haven't checked, in that case, revert it now :)

Yeah I guess supporting only views for ajax would be something that is easy enough to justify.

The idea to use an exposed filter would probably resolve some of the issues. I'm just hoping it doesn't introduce new ones.

It's been in for at least a year, so too late for a revert ;)

A crap :)

I'm already working on a patch, I'll upload it as soon as I have something working.

Honestly I find this huge list of issues a bit strange. We are using facets in a few projects with Ajax and it's working quite well.

In order to get it to work properly, we have had to structure our search page view, exposed filter form and facets carefully using the core block layout mechanism.

For what it's worth, on a simple view with a single facet, the AJAX integration from #3073444: Create views plugins to render facets and summaries in filters and areas works, though I'm also using Better Exposed Filters.

This could also be included in the list: https://www.drupal.org/project/facets/issues/3204660

The facets module does not work with Ajax.

There are many issues regarding Facets + Ajax, and tens of patches being submitted. I just updated to Facets 2.0 (on Drupal 9.2.10) and my view pages with facet blocks are not working. Various js errors in the console. This is also the case with a fresh clean Drupal setup. I am having to go back into all the various patches/issues and find something that works with the latest Facets 2.0. Nothing works.

Even though this is an open source project there must be a better way to manage this. This functionality is very common and is to be expected especially from a powerful platform such as Drupal.

I am prepared to help. If a maintainer wants to discuss this with me and how I can help then I am all ears. But right now, it may not be worth planning to use drupal for any website requiring facet/filtering functionality, which most do.

@hga77 We can always use extra help. Feel free to join #search in the drupal slack and let us know how you want to help.
While most of the contributors lack time, ajax is a high priorityfor us, now that most other features are stable.

Changed priority to major for this META issue to point out the importance of this issue, having several child issues reporting problems.

I'm currently using the latest 2.0 version of Facets (2.0.6) and I'm forced to render my facets in my view page via twig:

    <div class="facets">
      {{ drupal_block('facet_block:facet1', wrapper=false) }}
      {{ drupal_block('facet_block:facet2', wrapper=false) }}
      {{ drupal_block('facet_block:facet3', wrapper=false) }}
    </div>

Rendering the facets this way doesn't work with Ajax and exposed filters. I've got BEF and whenever I try to sort or filter, the facets disappear. It loads fine on initial page load, after that it just disappears. Rendering the facet via the Block UI works just fine and the facets persist after each ajax request.

I've added tried the following different patches:

https://www.drupal.org/project/facets/issues/3052574
https://www.drupal.org/project/facets/issues/3013795

But none of them have fixed the issue. Any ideas on what could be wrong?

can someone help me with this issue : https://www.drupal.org/project/facets/issues/3350613
