FactoryGirl, 2 times creates user? - ruby-on-rails-3

Question

I really dont understand of making assotiations. In spec_helper I have got
def log_in_user
user = User.find_by_name 'User1'
user = FactoryGirl.create :user1 unless user
sign_in user
end
in rspec
let(:product) { FactoryGirl.build :product_A }
describe "GET confirm purchase" do
it "xxx" do
log_in_user
Product.should_receive(:find_active_by_id).with("1").and_return(product)
...
end
end
factories.rb
FactoryGirl.define do
factory :user do
encrypted_password 'abcdef1'
confirmed_at Time.now
factory :user1 do
email 'user1#test.com'
name 'User1'
year 1984
end
end
factory :product do
factory :product_A do
name "product A"
association :user, factory: :user1
end
end
end
when I run test case an exception occures:
ActiveRecord::RecordInvalid: Validation failed: Email has already been taken
It looks like user1 is creating 2 times, one in log_in_user and the second one in factory: association :user, factory: :user1
I am right? If yes, how can I solve this? I want to create user and have assotiation defined in factory product

Answer 1

When you factory :product_A it is automatically calling the factory for :user1.
Then you factory :user1 again in the log_in_user, but the validation on unique emails is preventing the second :user1 from being created.
I would recommend you make email a sequence like so:
FactoryGirl.define do
sequence :email do |n|
"user#{n}#test.com"
end
factory :user do
encrypted_password 'abcdef1'
confirmed_at Time.now
factory :user1 do
email
name 'User1'
year 1984
end
end
factory :product do
factory :product_A do
name "product A"
association :user, factory: :user1
end
end
end
Then, I would alter the sign_in_user to take an (optional) user as an option like this:
def log_in_user(user)
user =|| User.find_by_name 'User1'
user =|| FactoryGirl.create :user1
sign_in user
end
And modify your test case to pass that user object to the login:
let(:product) { FactoryGirl.build :product_A }
describe "GET confirm purchase" do
it "xxx" do
log_in_user(product.user)
Product.should_receive(:find_active_by_id).with("1").and_return(product)
end
end
