active_admin/formtastic ignoring polymorphic associations
- by James Maskell
I'm currently having trouble with the form for a polymorphic association in active_admin in Ruby on Rails.
I have three models set up: offices, companies and users. Both companies and users can own an office. My models are set up as follows:
class Office < ActiveRecord::Base
belongs_to :ownable, :polymorphic => true
end
class User < ActiveRecord::Base
has_many :offices, :as => :ownable
end
class Company < ActiveRecord::Base
has_many :offices, :as => :ownable
end
active_admin doesn't allow me to edit the owner on its forms, but does show it correctly on the index and show pages (including links to the company or user).
I've tried playing with formtastic to manually create the form but have not had any luck - the "ownable" fields just get ignored and everything else renders properly.
To be clear: I want to be able to edit the owner of the Office model on the new and edit fields in active_admin.
Can anyone offer any help? :)
