Exception thrown when calling whenPivotLoadedAs when preventAccessingMissingAttributes is active

[gerardnll]

• Laravel Version: 9.36.1
• PHP Version: 8.1.6
• Database Driver & Version: not applicable

Description:

Having Model::preventAccessingMissingAttributes(true); and trying to make use of a JsonResource whenPivotLoadedAs() method results in a Illuminate\Database\Eloquent\MissingAttributeException. Is this an expected behaviour? Shouldn't the whenPivotLoadedAs method check for the relation existence by calling relationLoaded instead of trying to access the relationship directly?

I could do a PR with that change.

I think you are right. My tests are failing because this too :)

I'm also seeing issues. I think part of the problem is that Laravel loads foo_id as pivot_foo_id and gets confused because it's not foo_id.

I'm having the exact same issue in a JSON resource where I am using whenPivotLoaded to decide whether or not to include pivot fields.

This has been fixed in v9.38.0, see #44792
