When displaying any group entity (url/group/), the debug information (when enabled) in the HTML is not shown.
The expected output could be something like that:
<!-- START RENDERER -->
<!-- CACHE-HIT: No -->
<!-- CACHE TAGS:
* group_view
* group:2
* config:system.site
-->
<!-- CACHE CONTEXTS:
* url.site
* languages:language_interface
* theme
* user.permissions
* url.path
-->
<!-- CACHE KEYS:
* entity_view
* group
* 2
* full
-->
<!-- CACHE MAX-AGE: -1 -->
<!-- PRE-BUBBLING CACHE TAGS:
* group_view
* group:2
-->
<!-- PRE-BUBBLING CACHE CONTEXTS:
* url.site
* languages:language_interface
* theme
* user.permissions
-->
<!-- PRE-BUBBLING CACHE KEYS:
* entity_view
* group
* 2
* full
-->
<!-- PRE-BUBBLING CACHE MAX-AGE: -1 -->
<!-- RENDERING TIME: 0.209016085 -->
<!-- THEME DEBUG -->
<!-- THEME HOOK: 'group' -->
<!-- FILE NAME SUGGESTIONS:

<!-- 💡 BEGIN CUSTOM TEMPLATE OUTPUT from 'themes/custom/egm_theme/templates/content/group.html.twig' -->
but by default we have something like:
<!-- THEME DEBUG -->
<!-- THEME HOOK: 'group' -->
<!-- FILE NAME SUGGESTIONS:
* group--2--full.html.twig
* group--2.html.twig
* group--egm-event--full.html.twig

-->
If we devel the entity (/devel/render/group/): we can also see
"#view_mode" => "full"
"#cache" => array:3 [▼
"tags" => array:2 [▼
0 => "group_view"
1 => "group:4"
]
"contexts" => []
"max-age" => -1
]
"#theme" => "group"
if i dig in the GroupViewBuider / EntityViewBuilder: $this->isViewModeCacheable($view_mode)
returns FALSE for view mode 'full', and inside isViewModeCacheable() in the entityViewBuilder class,
in a vanilla installation $this->entityDisplayRepository->getViewModes($this->entityTypeId) could return empty as no view modes are created (/admin/structure/display-modes/view)
If a 'Full content' view with id 'full' is created, then
If we devel the entity (/devel/render/group/): we can also see
"#view_mode" => "full"
"#cache" => array:5 [▼
"tags" => array:2 [▶]
"contexts" => []
"max-age" => -1
"keys" => array:4 [▶]
"bin" => "render"
]
"#theme" => "group"
and the debug in the HTML now is correct
In the problem explained
I think the easiest could be to create the 'full' display view when the module is being installed.
The view does not need to be enabled, just needs to exists as it seems somewhere it treats the 'default' as 'full' and voila.
I was comparing the code with the group module, and they have that view created during installation (event it is not enabled)
Active
3.2
Code
If that is the approach, then i assume the same view should be created in a hook_update for those with the module already enabled and the view not created.
The other option i was considering was to alter the GroupViewBuilder and overwrite isViewModeCacheable(), but might be better the view approach :)
