Rails 3, FactoryGirl: wrong number of arguments (1 for 0) (ArgumentError)

I'm working on the ruby on rails tutorial, but I encounter problems when testing using FactoryGirl. here is my error information:

and here is my factories.rb:

FactoryGirl.define do
  factory :user do
    user.name "abc"
    user.email "[email protected]"
    user.password "foobar"
    user.password_confirmation "foobar"
  end
end

here is the code I use in user_controller_spec.rb:

before(:each) do
  @user = FactoryGirl.create(:user)
end

I've tried the methods in previous asked questions, but they did not work. Can anybody help with me? Thanks!

Your factory file should just be:

FactoryGirl.define do
  factory :user do
    name "abc"
    email "[email protected]"
    password "foobar"
    password_confirmation "foobar"
  end
end

That'll work.

You are using a local variable 'user' in your initial version. Problem is that there has been no local variable user passed to, or defined in the block. As one of the commenters above points out - if you want to call user.name then you have to pass |user| to the block. i.e.

FactoryGirl.define do
  factory :user do |user|
  etc.

But this is not necessary in FactoryGirl. You can just do it as I typed it above.

I'd recommend reading https://github.com/thoughtbot/factory_girl/wiki/Usage - it's very accessible even if you're just learning Rails (as I did) via the tutorial :-)
