Question

I have a User model and a Friendship-Model.

class Friendship < ActiveRecord::Base   belongs_to :sender, :class_name=>'User', :foreign_key=>'sender_id'   belongs_to :receiver, :class_name=>'User', :foreign_key=>'receiver_id'    validates_presence_of :receiver_id, :sender_id   validates_associated :receiver, :sender end  class User < ActiveRecord::Base   has_many :sent_friendships, :class_name => 'Friendship', :foreign_key => 'sender_id', :dependent => :destroy   has_many :received_friendships, :class_name => 'Friendship', :foreign_key => 'receiver_id', :dependent => :destroy end 

and one of my rspec-test is

describe Friendship do    before(:each) do     @valid_attributes = {       :sender_id => 1,       :receiver_id => 2,       :accepted_at => nil     }   end    it 'should not be valid with non-existant receiver_id' do     f = Friendship.new(@valid_attributes)     f.receiver_id = 99999     f.should_not be_valid   end end 

The test shouldnt be valid, because there is no User with user_id 9999. But the test say’s the friendship-model is valid.

Why the hell?

EDIT:

But I want to test like mentioned -> without assigning the sender directly. Isn’t that possible??

Answer 1

If you want your model to work that way, change this:

validates_presence_of :receiver_id, :sender_id 

to this:

validates_presence_of :receiver, :sender
