[Bug] Problem during CRUD generation and relationships.

[pedja1982]

Bug report

What I did

I created two models, "Category" and "Product." Products have a category ID in the table. When I generate CRUD (Create, Read, Update, Delete) operations in Devtools, I don't get a select option; instead, I get a regular input where I need to enter the category ID.

What I expected to happen

I expected the CRUD to generate a dropdown/select field instead of an input field.

What happened

CRUD works without a relationship. I manually enter the integer.

What I've already tried to fix it

I tried to find it in the documentation, but such a basic thing does not exist in the documentation. The documentation is quite poor.

Is it a bug in the latest version of Backpack?

After I run composer update backpack/crud the bug... is it still there? YES
