WHY

BEFORE - What was wrong? What was happening before this PR?

Heads up: This is working, but it's just a POC to be discussed. We may need to add documentation about it if we decide to do it.

Reported in #5204 and we also had some discussions about it.

In my understanding, and the user reporting the issue, all the operations should be performing their queries over the Panel Query. This would be a huge change in behavior and we may miss use cases that we will break doing such a global change on a non-breaking version.

AFTER - What is happening after this PR?

I've thought about this for a while and decided to "experiment" with the feature in the show operation behind a configuration.

I think this is the way to go now, without risking breaking all people apps. We may eventually turn it true by default in a future version.

HOW

How did you achieve that, in technical terms?

I introduced the usePanelQuery config in show operation, that will tell the operation if it should perform the findOrFail in the model, or in panel query.

Is it a breaking change?

I don't think so no, it need to be enabled.

How can we test the before & after?

Steps described in the linked issue. But to sum up, create a constrain on the crud query and watch it being applied in the List but not in the show operation.

I like the approach yes. A bit scared to do it, but yeah, we should probably do something like this. Only one question

$this->data['title'] = $this->crud->getTitle() ?? trans('backpack::crud.preview').' '.$this->crud->entity_name;
if ($this->crud->get('show.usePanelQuery')) {
$this->data['entry'] = $this->crud->query->withTrashed()->findOrFail($id);
$this->data['entry'] = $this->crud->setLocaleOnModel($this->data['entry']);

Hmm... something here is fishy to me. Why aren't we using getEntryWithLocale() and we are using setLocaleOnModel()? Looks to me like we're using a setter, instead of a getter.

Would this do the same thing or no?

Suggested change
$this->data['entry'] = $this->crud->setLocaleOnModel($this->data['entry']);
$this->data['entry'] = $this->crud->getEntryWithLocale($id);
