railstutorial.org - undefined method `Factory'

Question

I\'m attempting to follow railstutorial.org, and am currently on Chapter 7, where you start using factories: http://railstutorial.org/chapters/modeling-and-viewing-users-two#sec

Answer 1

I was determined to use the newest version of Factory Girl, so I tried to adapt the code. Didn't work for me, so I used

gem 'factory_girl_rails', '1.0'

in the Gemfile to lock the version at 1.0

bundle update

restart spork and autotest and it worked.

Answer 2

I had this problem, but it was because I had placed the factory girl gem under the development section instead of the test section of the Gemfile. Once under the test section, it worked. One difference I note between my entry and yours is that mine specifies 1.0:

group :test do
  gem 'rspec-rails', '2.6.1'
  gem 'webrat', '0.7.1'
  gem 'factory_girl_rails', '1.0'
end

Answer 3

My solution: I've accidentally included it in the :development block, and simply had to move it to the :test block

(I've listed it here, because it might help someone who doesn't follow the tutorial correctly)

Answer 4

I got this exact same error message. I just restarted my Spork server and Autotest and everything went green for me.

Answer 5

Maybe you should try the new syntax (see github readme of factory girl)

FactoryGirl.define :user do |user|
  user.name                  "Michael Hartl"
  user.email                 "mhartl@example.com"
  user.password              "foobar"
  user.password_confirmation "foobar"
end

Answer 6

For those finding this page now: note where you once used "FactoryGirl" you must now use "FactoryBot" in your tests. From the thoughtbot announcement page:

"We’re renaming factory_girl to factory_bot (and factory_girl_rails to factory_bot_rails). All the same functionality of factory_girl, now under a different name."
