How can I setup and use factory_girl_rails properly? - ruby-on-rails

Question

I think I have a problem with configuring FactoryGirl with rails. I initially followed ASCIIcasts #275: how i test, but rake is giving me NameError: uninitialized constant ...
Am I missing something? Is it possible that some config file are wrong? I'm pretty new to RSpec and Rails.
I'm using Rails 3.2.2 + Mongoid + RSpec + factory_girl_rails.
Error:
Failures:
1) User should save user with valid required fields
Failure/Error: let(:user) { FactoryGirl.build(:valid_user) }
NameError:

FactoryGirl.define do
factory :valid_user do

end
end

require 'spec_helper'
describe User do
let(:user) { FactoryGirl.build(:valid_user) }
it "should save user with valid required fields" do

RSpec.configure do |config|
config.infer_base_class_for_anonymous_controllers = false
config.include FactoryGirl::Syntax::Methods
end

It's usually helpful to output the whole error, or at least the whole first sentence -- you haven't even told us what the missing constant is!
UPDATE: Thanks for the whole error. When you define the factory :valid_user, Factory Girl will automatically assume it is for a model named ValidUser. To get around this, you can either name your factory :user (assuming you have a User model), or you can try:
FactoryGirl.define do
factory :valid_user, :class => User do
name 'somename'
email 'a#b.com'
password 'somepassword'
end
end
Alternatively, if you want to have a couple different types of User factories, you can use:
FactoryGirl.define do
factory :user do
# set some attrs
end
factory :valid_user, :parent => :user do
name 'somename'
email 'a#b.com'
password 'somepassword'
end
factory :invalid_user, :parent => :user do
# some other attrs
end
end

You can declare factory like this........
Factory.define :organization do |g|
g.name 'Test Organization'
g.phone_number '5345234561'
g.website_url 'www.testorg.com'
g.city 'chichago '
g.association :state
end
And use it in organization_spec like this.....
require 'spec_helper'
describe Organization do
before :each do
#state = Factory :state
#organization = Factory :organization ,:state => #state
end
it "should be invalid without a name" do
#organization.name = nil
#organization.should_not be_valid
end
end
And enjoy!!!!!!!!!!!!!!!!
