Question

I have the following code

class Involvement < ActiveRecord::Base
   belongs_to  :matter
   belongs_to   :contact
end

class Contact < ActiveRecord::Base
    has_many :involvements, :order => "position", :dependent => :destroy
    has_many :matters, :through => :involvements, :source => :matter
end

class Matter < ActiveRecord::Base
    has_many :involvements
    has_many :plaintiffs, :through => :involvements, :source => :contact
    has_many :defendants, :through => :involvements, :source => :contact
end

I got the error while running the matters page.

ActiveRecord::HasManyThroughSourceAssociationNotFoundError in Matters#new

Could not find the source association(s) :contact in model Involvement. Try ‘has_many :plaintiffs, :through => :involvements, :source => ‘. Is it one of ?

I have got this error while upgrade the rails 2.3.11 project in rails 3.0.10,

Any one know the solution of it, or reason why this breaks in rails 3.0.10

And as it deprecate in rails 3.0.10 it gives me the error, when I was removing it, all the association working fine…
