Rspec: Using factories in other factories - ruby-on-rails

Question

I'm writing a cost for a create method that will add a comment to a post.
The comment belongs to a user and a post. And a post belongs to a user.
When I run my test I get a validation error saying that the username and email have already been taken. I've tried using build as well as build_stubbed in both my factories and in the test, but neither of them worked. I think it has to do with the fact that I'm using create, but I'm not entirely sure.
Any advice would be much appreciated
Here are my factories:
users.rb
FactoryGirl.define do
factory :user do
username "test_user"
email "test_user#email.com"
password "password"
end
factory :user_2, class: User do
username "test_user_2"
email "test_user_2#email.com"
password "password"
end
factory :invalid_user, class: User do
username ""
email ""
password ""
end
end
outlets.rb
FactoryGirl.define do
factory :outlet do
category "vent"
title "MyString"
body "MyText"
urgency 1
user factory: :user
end
factory :outlet_2, class: Outlet do
category "rant"
title "MyString_2"
body "MyText_2"
urgency 2
user factory: :user_2
end
factory :invalid_outlet, class: Outlet do
category "qualm"
title ""
body ""
urgency 3
user factory: :user
end
end
comments.rb
FactoryGirl.define do
factory :comment do
body "This is a comment"
user factory: :user
outlet factory: :outlet_2
end
factory :invalid_comment, class: Comment do
body "This is a comment"
user nil
outlet nil
end
end
Here is my test:
describe 'create' do
context 'with valid attributes' do
let(:outlet) { FactoryGirl.create(:outlet) }
let(:valid_comment_params) { FactoryGirl.attributes_for(:comment) }
it "creates a new comment" do
expect { post :create, params: { id: outlet, :comment => valid_comment_params } }.to change(Comment, :count).by(1)
end
end
end
Here are my models:
class Comment < ApplicationRecord
belongs_to :user
belongs_to :outlet
validates :body, :user, :outlet, presence: true
validates :body, length: { in: 1..1000 }
end
class Outlet < ApplicationRecord
belongs_to :user
has_many :comments
validates :category, :title, :body, :urgency, :user, presence: true
validates :title, length: { in: 1..60 }
validates :body, length: { in: 1..1000 }
validates :urgency, numericality: { only_integer: true, greater_than_or_equal_to: 1, less_than_or_equal_to: 10 }
validates :category, inclusion: { in: ['vent', 'rant', 'qualm'] }
end
class User < ApplicationRecord
has_many :outlets
has_many :comments
validates :username, :email, :encrypted_password, presence: true
validates :username, :email, uniqueness: true
validates :password, length: { in: 5..30 }
# Include default devise modules. Others available are:
# :lockable, :timeoutable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable, :omniauthable
end

Answer 1

So the problem here is you keep trying to create a user with the same email and username that you just created another user with. In order to avoid this in your factories, you should strive to make the values dynamic. Since the main issues currently are the uniqueness validations, lets start with those.
factory :user do
sequence(:username) { |n| "test_user#{n}" }
sequence(:email) { |n| "test_user#{n}#email.com" }
password "password"
end
that way, you can use the same factory to create 2 distinct users
user = FactoryGirl.create :user
user_2 = FactoryGirl.create :user
