Setting roles through rolify in FactoryGirl definition

问题

I am using devise, rolify and cancan. I'm also using rspec with FactoryGirl for testing. Right now I'm working on some tests and I want to define users with different roles for those tests. Here is my current guess for how to do that using FactoryGirl:

FactoryGirl.define do
  factory :user do
    name 'Test User'
    email 'example@example.com'
    password 'please'
    password_confirmation 'please'
    # required if the Devise Confirmable module is used
    confirmed_at Time.now

    factory :admin do
        self.has_role :admin
    end

    factory :curator do
        self.has_role :curator
    end

    factory :super_admin do
        self.has_role :super_admin
    end
  end
end

Here are some of my tests which don't seem to be written correctly: require 'spec_helper'

describe "Pages" do
    subject { page }

    before do
        @newpage = FactoryGirl.create(:page)
        @newpage.save
    end

    context 'not logged in' do
        it_behaves_like 'not admin'
    end

    context 'logged in' do

        context 'as user' do
            before do
                @user = FactoryGirl.create(:user)
                sign_in @user
            end

            it_behaves_like 'not admin'
        end

        context 'as curator' do
            before do
                @curator = FactoryGirl.create(:curator)
                sign_in @curator
            end

            it_behaves_like 'not admin'
        end

        context 'as admin' do
            before do
                @admin = FactoryGirl.create(:admin)
                sign_in @admin
            end

            it_behaves_like 'admin'
        end

        context 'as super admin' do
            before do
                @super_admin = FactoryGirl.create(:super_admin)
                sign_in @super_admin
            end

            it_behaves_like 'admin'
        end
    end
end

When I run the specs I these are my errors:

1) Pages logged in as admin behaves like admin can show page 
 Failure/Error: Unable to find matching line from backtrace
 NoMethodError:
   undefined method `has_role=' for #<User:0x007f883384d178>

2) Pages logged in as curator behaves like not admin can show page

3) Pages logged in as super admin behaves like admin can show page

回答1:

I would rather use FactoryGirls after(:create) callback to create roles (also see this issue for Rolify).

Furthermore the method has_role? is used to check if a user has a specific role, to set a specific role you should use the add_role method.

FactoryGirl.define do
  factory :user do
    name 'Test User'
    email 'example@example.com'
    password 'please'
    password_confirmation 'please'
    # required if the Devise Confirmable module is used
    confirmed_at Time.now

    factory :admin do
        after(:create) {|user| user.add_role(:admin)}
    end

    factory :curator do
        after(:create) {|user| user.add_role(:curator)}
    end

    factory :super_admin do
        after(:create) {|user| user.add_role(:super_admin)}
    end
  end
end
