Incompatibility with strict loading about administrate

[pablobm]

Thank you for raising this. My current impression is that this cannot be avoided automatically, and it's on Administrate users to ensure that these relationships are loaded correctly. After all, that's generally the case when strict loading is in effect.

Fortunately, the fix should be straightforward: eager load the appropriate relationships, for example using the scoped_resource hook.

I have an example app where Thing.has_many :parts. To avoid this issue, I added the following lines:

# app/controllers/admin/things_controller.rb
...
    def scoped_resource
      super.includes(:parts)
    end
...

And:

# app/controllers/admin/parts_controller.rb
...
    def scoped_resource
      super.includes(:thing)
    end
...

Now the relationship is loaded explicitly and will not cause an issue when strict loading.

I'm going to close this now, but please do let use know if you have any feedback.
