I have a ‘user’ resource w route => map.resources :users
user model is defined as self-referential
class User < ActiveRecord::Base
has_many :relationships_as_befriender, :foreign_key =>
‘befriender_id’, :class_name => ‘User’
has_many :relationships_as_friend, :foreign_key => ‘friend_id’,
:class_name => ‘User’
has_many :friends, :through => :relationships_as_friend
has_many :befrienders, :through => :relationships_as_befriender
…
I created the nested ‘relationship’ resource
class Relationship < ActiveRecord::Base
set_primary_key :relation_id
belongs_to :befriender, :foreign_key => “befriender_id”, :class_name
=> “User”
belongs_to :friend, :foreign_key => “friend_id”, :class_name =>
“User”
…
if I had a one-to-many , I know that the route should be created like
that…
map.resources :users do |users|
users.resources :relationships
end
but if I require /users/1/relationships , it will use the user_id
as a foreign_key… and fail
relationship_url failed to generate from {:action=>“show”,
:user_id=>“1”, :controller=>“relationships”}, expected:
{:action=>“show”, :controller=>“relationships”}, diff: {:user_id=>“1”}
how should I write teh routes ? (tips or links to solution
accepted… ;-))
