Rails: Factory Girl Can't

Question

Just starting with a factory girl, and I ran into the problem of sequencing: in particular, it does not increase. I tried to change the database type by upgrading from factory_girl 1.3.2 to 2.0.0.beta1 (and factory_girl_rails from 1.0 to 1.1.0.beta1), tried to recreate the database, but the same problem - the sequence will not increase and I get an error checks after the first time I insert a unique field.

Any help is greatly appreciated. Code and trace below:

/spec/models/user.rb

require 'spec_helper' describe User do describe "test user factory is correct" do user = Factory(:user) it "should have an email ending in example.com" do #user.email.should match " [e-mail] " end it "should have a password of foobar" do user.password.should == 'foobar' end it "should have a password confirmation field of foobar" do user.password_confirmation.should == 'foobar' end end end 

/spec/factories/user.rb

 Factory.define :user do |f| f.sequence(:email) { |n| puts "Email ##{n}"; "factory_#{n}@example.com" } f.password 'foobar' f.password_confirmation { |p| p.password } end 

Trace:

Answer 1

Your problem is not with the factory girl. When creating a user instance, you need to do this from the inside before the block so that a new user is created for each test run. The user variable must also be an instance variable (i.e., with the @ prefix)

 require 'spec_helper' describe User do describe "test user factory is correct" do before(:each) do @user = Factory(:user) end it "should have an email ending in example.com" do @user.email.should match " [e-mail] " end it "should have a password of foobar" do @user.password.should == 'foobar' end it "should have a password confirmation field of foobar" do @user.password_confirmation.should == 'foobar' end end end 

Answer 2

With the latest syntax :

 FactoryGirl.define do sequence :email { |n| "test#{n}@email.com" } factory :user do name "John Doe" email { FactoryGirl.generate(:email) } end end 

Answer 3

Have you identified the sequence separately? Here is an excerpt from one of my factory files:

 Factory.sequence(:email) {|n| "person#{n}@example.com" } Factory.define :user do |f| f.name "John Doe" f.email { Factory.next :email } end 

Answer 4

I'm not sure why this is happening, but here are some tips:

• Get a user who is not saved in the database:

  user = Factory.build (: user)

Or

• use before each block:

  before (: each) do @user = Factory (: user) end

  (then change the "user" variables to "@user")
