FactoryGirl Validation failed: Email has already been taken - ruby-on-rails

Question

I have next code:
My users_controller_test.rb:
require 'test_helper'
class Api::Be::UsersControllerTest < ActionController::TestCase
setup do
admin = FactoryGirl.create :admin
store = FactoryGirl.create(:store, admin: admin)
store.ug_default = UgDefault.new
store.save
customer = FactoryGirl.create :customer
customer.store_id = store.id
customer.save
end
test "should show user" do
get :show, store_id: store.id, u: admin.u_token
assert_response :success
json = response.body
data = JSON.parse(json)
assert_equal 'ok', data['status']
end
end
In my sequences:
sequence :email do |n|
"email-#{n}#example.com"
end
And my factories:
FactoryGirl.define do
factory :admin do
end
end
And
FactoryGirl.define do
factory :store do
admin
name {generate :string}
subdomain {generate :string}
linked_domain {generate :string}
end
end
And
FactoryGirl.define do
factory :customer do
end
end
And
FactoryGirl.define do
factory :user do
first_name {generate :string}
last_name {generate :string}
email {generate :email}
password_digest {generate :password_digest}
login_attempts 1
company_name {generate :string}
phone {generate :string}
u_token 'u'
end
end
Admin and Customer inherited from User.
Now I have Validation failed: Email has already been taken error in line customer = FactoryGirl.create :customer. I've tried to clean database. rake db:test:prepare didn't work too.

Answer 1

Can it be that your :admin and :customer factories does not inherit from your :user factory? Does it work if your :admin and :customer factories are defined like this?
FactoryGirl.define do
factory :admin, parent: :user do
end
factory :customer, parent: :user do
end
end
