OK I started with this question:
RnR: Database normalization, rails models and associations
I’ve set up the models as outlined. I’m trying to use the Rails_admin gem for the data maintenance. The issue is every polymorphic child table gives the following error:
undefined method `klass' for nil:NilClass
However the parent record for location shows up, with fields for the associations in the list, but I cannot edit them. I was thinking maybe seed data would help, but I’m not sure what the format for the object_type should be? Is it case-sensitive, singular or plural?
Figured it out, was using the same name for the association between two different polymorphic associations…
