I have a simple CMS I''m creating, and the primary model is the
"listing". A listing habtm (has_and_belongs_to_many) categories (up to
two) - allowing the listing to print its categories and a category to
print its listings. I also need subcategories, which are different from
categories in two ways: a listing can have as many subcategories (from
it''s two categories) as it wishes, and subcategories are displayed
differently in both administration and display views.
So what I have is:
Class Listing < ActiveRecord::Base
has_and_belongs_to_many :categories
has_and_belongs_to_many :subcategories
...
end
Class Subcategory < ActiveRecord::Base
has_and_belongs_to_many :listings
belongs_to :categories
end
Class Category < ActiveRecord::Base
has_and_belongs_to_many :listings
has_many :subcategories
...
end
Is this allowed? I ask because I can''t create a listing with
subcategories (from the admin UI) - the UI works fine, there are no
errors, but the new listing has no subcategories and the MySQL DB isn''t
updated.
