This relationship is giving me trouble: class Show < AR::Base has_many :segments end class Segment < AR::Base belongs_to :show has_one :media #this has no PK/FK relation end A Segment is "linked" to Media by Media.name, which is the result of concatenating Segment.name and Segment.part. As I said there are is no

Since has_one :colour :through => :species isn''t supported (for some reason unknown to me), can anyone forsee any problems that the following workaround might cause (in the Photo class). has_many :artists, :through => :artist_photos has_one :artist_photo So effectively, the has_many statement gives me the through functionality I need, but the has_one restricts the program to only

How can I achieve granular control over the validation for different controllers? I create users from an administration controller, but I don''t want to fill in all their information fields, just have their name and email address.

Just starting a new thread so that it''s easy to follow. I just submitted a patch at trac to add a new class method called "set_default_values" ( not a great name I think ), which lets you do all kinds of crazy stuff with setting default values.

Hi, I am thinking about writing an acts_as_fox plugin that defines an after_find callback method. If I do this what will happen if a user creates a model that acts_as_fox but this model has it''s own after_find callback method?
