Bug report

Backpack does not guess the column attributes for subfields. Create a HasMany relationship and try to display it like in the example below.

CRUD::column('articles')->type('relationship')->subfields([['name' => 'category_id']]);

Undefined array key "type"

Is it a bug in the latest version of Backpack?

Yes

Hey @susanu indeed there is an inconsistency here that we should probably address, but i've already spent quite some time today trying to make this work, and it doesn't have a simple solution.

Inferring the attributes is not the biggest issue, but it breaks other parts of the functionality like the linkTo() macros for example. And it may be a breaking change also in other places I am not aware now.

I will postpone working on this on the next major version so that we can confidently introduce this, even with unknown breaking changes that we can document/fix when discovered.

For now, we need to keep manually adding the attributes to subfields in the columns.

Cheers
