Question

I have several rich join models and I was wondering if it was possible or rails convention to have the following:

has_many :users through => rich_association_one
has_many :rich_association_one

has_many :users through => rich_accociation_two
has_many :rich_association_two

Thanks

Answer 1

it may be possible, but i think you will have to use different aliases – as you seem to expect, i think that calling has_many :users twice will bring doom upon your model.

try something like this :

has_many :rich_association_one
has_many :association_one_users, 
         :through => :rich_association_one, 
         :class_name => "User"

has_many :rich_association_two
has_many :association_two_users, 
         :through => rich_accociation_two, 
         :class_name => "User"

more basic info on has_many options is available on RoR guides.
