forgery not producing unique values

[greggroth]

When used with FactoryGirl, i.e.

factory :user do
   email Forgery(:internet).email_address
end

and you attempt to create records:

5.times { FactoryGirl.create(:user) }

will return five records with the same e-mail address. This creates a problem if the model validates the uniqueness of the e-mail address.

Try this:

factory :user do
  email { Forgery(:internet).email_address }
end

When you just do email Forgery(:internet).email_address the email address is generated once when the factory is loaded. When you use the block form email { Forgery(:internet).email_address } the email is generated every time the factory is used to build an object. This still won't guarantee uniqueness, though, so I recommend you use sequences. They're much faster for testing as well.

I see. Thank you for explaining the difference.
