This seems like it should be possible, and a scan of the ash_admin code shows me that it might be possible, but I can also see why it might not be.
I’ll simplify the problem down: I have an Item resource and a Category resource. The Item resource has a :category_id attribute and a belongs_to relationship to the Category. What I would love to have in ash_admin is a select box for Category on the :create and :update forms, so I don’t have to copy/paste the :category_id from somewhere else. This seems like it would be a normal convenience for an admin tool.
If the answer’s “yes, of course it can do that and you must be configuring it incorrectly” then I’ll provide further detail. But I do have that small hunch that “no, it’s not possible because of xyz”.
Thanks
