Question

I have 2 models, User and Bucket. User has_many Buckets and a Bucket belongs_to a User.

In factories.rb, I have:

Factory.define :user do |user|
  user.email  "[e-mail]"
  user.password               "foobar"
  user.password_confirmation  "foobar"
end


Factory.sequence :email do |n| 
  "person-#{n}@example.com"
end

Factory.define :bucket do |bucket|
  bucket.email        "[e-mail]"
  bucket.confirmation false
  bucket.association :user
end

and I have a login_user module as follows:

def login_user
    before(:each) do
      @request.env["devise.mapping"] = Devise.mappings[:user]
      @user = Factory.create(:user)
      #@user.confirm!
      sign_in @user
    end
  end

I am using Spork and Watch and my Buckets_controller_spec.rb is as simple as:

describe "User authenticated: " do

   login_user  

   @bucket = Factory(:bucket)

   it "should get index" do
     get 'index'
     response.should be_success
   end
...
end

The error is always the same:

Failures:

  1) BucketsController User authenticated: should get index
     Failure/Error: Unable to find matching line from backtrace
     ActiveRecord::RecordInvalid:
       Validation failed: Email has already been taken
     # ./lib/controller_macros.rb:12:in `block in login_user'

And it only happens when I have the Factory(:bucket). The login works fine when I don’t add the Factory(:bucket).

It’s always the same error. I have tried adding :email => Factory.next(:email) to the user, but no success.

Edit:

In rails c test:

ruby-1.9.2-p180 :019 > bucket = Factory(:bucket, :email => "[e-mail]")
    ActiveRecord::RecordInvalid: Validation failed: Email has already been taken

    ruby-1.9.2-p180 :018 >   Bucket.create(:email => "[e-mail]")
     => #<Bucket id: 2, email: "[e-mail]", confirmation: nil, created_at: "2011-04-08 21:59:12", updated_at: "2011-04-08 21:59:12", user_id: nil> 

Edit 2:

I found out that the error is in the association, however, I don’t know how to fix it.

  bucket.association :user

Answer 1

When you define a factory with an association you need to give the factory an object to associate with whenever you use the factory.

This should work:

describe "User authenticated: " do
  login_user
  @bucket = Factory(:bucket, :user => @user)

  it "should get index" do
    get 'index'
    response.should be_success
  end
end

That way factorygirl knows to make a bucket which is associated with @user.
