Can't wrap my head around this...
class User < ActiveRecord::Base
has_many :fantasies, :through => :fantasizings
has_many :fantasizings, :dependent => :destroy
end
class Fantasy < ActiveRecord::Base
has_many :users, :through => :fantasizings
has_many :fantasizings, :dependent => :destroy
end
class Fantasizing < ActiveRecord::Base
belongs_to :user
belongs_to :fantasy
end
... which works fine for my primary relationship, in that a User can have many Fantasies, and that a Fantasy can belong to many Users.
However, I need to add another relationship for liking (as in, a User "likes" a Fantasy rather than "has" it... think of Facebook and how you can "like" a wall-post, even though it doesn't "belong" to you... in fact, the Facebook example is almost exactly what I'm aiming for).
I gathered that I should make another association, but I'm kinda confused as to how I might use it, or if this is even the right approach. I started by adding the following:
class Fantasy < ActiveRecord::Base
...
has_many :users, :through => :approvals
has_many :approvals, :dependent => :destroy
end
class User < ActiveRecord::Base
...
has_many :fantasies, :through => :approvals
has_many :approvals, :dependent => :destroy
end
class Approval < ActiveRecord::Base
belongs_to :user
belongs_to :fantasy
end
... but how do I create the association through Approval rather than through Fantasizing?
If someone could set me straight on this, I'd be much obliged!
