activerecord::hasmanythroughassociationnotfounderror: not find association :user_friends in model user

can help this? in advance.

you need check self-referential association. apparently missing concepts. can not add together 2 associations same name in single model, (only 1 of them respond).

you should add together has_many :user_friends, still missing other side of association, check example:

# user.rb has_many :user_friends has_many :friends, :through => :user_friends has_many :inverse_friendships, :class_name => "userfriend", :foreign_key => "friend_id" has_many :inverse_friends, :through => :inverse_friendships, :source => :user # user_friends.rb belongs_to :user belongs_to :friend, :class_name => "user"
