Hi everyone. I've made a default change to has_many :through associations that I felt was important to make before they're released. This is after some tickets and confusion I've seen regarding has_many :through.
class Connection < ActiveRecord::Base belongs_to :user belongs_to :channel end class Channel < ActiveRecord::Base has_many :connections has_many :contacts, :through => :connections, :class_name => 'User' end What's misleading in this case, is has_many :through isn't using :class_name to specify what model to load, it's using it to use the :user association in Connection as the source reflection. has_many :through is a unique association that actually uses the source reflection to get the class_name and foreign_key it needs for the query. Instead, change that model to: class Channel < ActiveRecord::Base has_many :connections has_many :contacts, :through => :connections, :source => :user end I apologize for the hassle, but you do get a descriptive and helpful error message: ActiveRecord::HasManyThroughSourceAssociationNotFoundError: Could not find the source association(s) contact or contacts in model Connection. Try 'has_many :contacts, :through => :connections, :source => <name>'. Is it one of :channel or :user? -- Rick Olson http://techno-weenie.net _______________________________________________ Rails-core mailing list Rails-core@lists.rubyonrails.org http://lists.rubyonrails.org/mailman/listinfo/rails-core
