Views individual subfield formatter support

Opening an initial MR to get the ball rolling on this. It's not 100% yet but functioning as expected at least so far.

hi, so far patch 74 does not work throwing php exception of field unknown

Try clearing cache and if still errors, please look at your logs and post here anything thats helpful. I'm not seeing any php errors in my testing.

Hi, I had cleared the cache. The scenario is as follows:
-) one vocabulary "country"
-) another vocabulary "area", where there is a custom field "items" with unlimited values. Its subfields are: "item" that is a reference to "country" and "inclusion" that is the type of inclusion of the country in that area.
-) a view on country vocabulary to show in which areas a country is. Contextual filter = term id, relationship = "Relate each Taxonomy term with a field_area_items_item set to the taxonomy term".
-) Showing field "Taxonomy term: Items" gives no output and there is no PHP error - first problem.
-) Showing field "Taxonomy term: Items:inclusion" throws PHP exception "Uncaught PHP Exception InvalidArgumentException: "Field field_area_items is unknown." at /web/core/lib/Drupal/Core/Entity/ContentEntityBase.php line 616" - second problem.

Let me know if you need more info.
thanks

The patch sort of works but multi-lingual results in some errors in the view that I'm not able to resolve immediately. The need for individual subfield formatters is low priority for now and I want to focus on getting a stable release out as well as features that hit a broader need.

Ok, I will wait. Let me just add that, as I wrote in https://www.drupal.org/project/custom_field/issues/3476033 ✨ Support not just values in custom template Active , for me the issue is not on subfields but on the custom field itself: when I try to use a custom field in a view of taxonomy terms in a multilingual site, it never works correctly: either it does not show anything, or it throws a PHP error, or it messes up the query and unrequested taxonomy terms show up.
While if I use directly its subfields in the view, the result is correct, just without the chance of selecting tokens or formatters.
Thanks for your precious work

Hi Andy, will you explicitly write here when the patch is ready for testing?

Is there any update on this?

Having multiple fields exposed in the views is working like a charm, we are just missing the part of displaying the values instead of keys.

Will this change be part of the current module?

I tried applying the changes as a patch:

        "patches": {
            "drupal/custom_field": {
                "Views individual subfield formatter support": "https://git.drupalcode.org/project/custom_field/-/merge_requests/74.diff"
            }
        }

and I got the following error:

The patch needs to be started over against the 3.1x branch. Alot has changed since and I havn't had a chance to revisit this. If not this next release, the one after I should get to it.

Let me take a wack at it. I need this functionality for a project.

Thank you for doing that. Let me test it one more time and I will let you know.

@emilorol, its somewhat more functional now but its NOT at all ready. This turned out to be way more complicated of a task than anticipated. I'm continuing to look work on it when i can but don't anticipate this making it into a release anytime real soon at this point.

@emilorol,

You can try working with the latest patch. I've mostly adapted cores EntityField implementation (see: core/modules/views/src/Plugin/views/field/EntityField.php) to our new views field plugin: /src/Plugin/views/field/CustomField.php

I havn't handled grouping and theres likely other stuff I've missed when you start messing with multi-lingual and such. The individual formatter settings work fine and the 'Multiple field settings' seems to work correctly.

I think its pretty close but it is quite complicated and can't say for 100% that its correct. It just seems to work at least from what i've tested and provides something solid to build on at this point with some other testing.

Having some issue apply thing patch with the 3.17 version:

        "patches": {
            "drupal/custom_field": {
                "Views individual subfield formatter support": "https://git.drupalcode.org/project/custom_field/-/merge_requests/74.patch"
            }
        }

@apmsooner,

Other than copy the changes manually I don't understand why I can't apply the patch.

Meanwhile I want to ask you, this patch will allow me to apply the subfields formatter when consuming them from a view, correct?

Example:

Before applying the patch:

After applying the patch:

Also will this solve the issue with expose view filters that give me a text field instead of a dropdown?

Note: in order for the status to display like a dropdown I had to use grouped filters

@emilorol,

From your screenshots, the sub-formatter appears to be working for you so I think your question is answered there no?

As for the filters, no this patch will not address any new filters. I don't really have a solution for select field filters as the field type could be shared across other entity bundles and have different widget settings so there's just not gonna be a way to do that for that reason. Looks like you found a workaround with Grouped filters for now.

No, the sub-formatter is not working for me yet as I have not been able to apply the patch, but I wanted to confirm we were talking about the same thing that is why I provided the screenshots. Very glad that we are.

About the filters I think that in the mid time beside the Grouped filter the other thing I have left if using code in the exposed filter form alter hook from the views.

All of this makes me think if there is a way to "trick" entity/form API to see the sub-field as a regular field for the widgets, formatters and exposed filters so that everything does not have to be re-implemented.

Note: for the patch could it be that it needs to rebase it so that I can apply it to the latest version?

@emilorol,

I would probably just composer remove your local custom_field module and do a git pull of this branch directly into your modules/contrib if your still having problems applying the patch. I just merged dev into this branch that has alot of changes as well. If you use ddev, just do a ddev restart if you pull this branch in and then clear the cache.

Automatically closed - issue fixed for 2 weeks with no activity.
