How do I create an admin role with Factory girl? - ruby-on-rails

Question

Ok so i want to test out features that need an admin user and i am trying to login as admin but in order to do that i need to have an admin user
here is my code
let(:user) { FactoryGirl.create(:user) }
let(:admin_role) { FactoryGirl.create(:role) }
FactoryGirl.define do
factory :user do
first_name "John"
last_name "Doe"
email "john#doe.com"
end
factory :role do
name "Admin"
end
end
how do i connect them I tried user.roles << user_role but got this error
/Users/matt/Sites/application/spec/controllers/directory_controller_spec.rb:16:in `block (3 levels) in <top (required)>': undefined local variable or method `user' for #<Class:0x007fa550890d80> (NameError)
Here is my models
class User < ActiveRecord::Base
has_many :roles, :through => :role_users
has_many :role_users
...
class Role < ActiveRecord::Base
has_many :users, :through => :role_users
has_many :role_users
...
class RoleUser < ActiveRecord::Base
belongs_to :role
belongs_to :user
end

Answer 1

spec/factories/user.rb
FactoryGirl.define do
factory :user do
first_name "John"
last_name "Doe"
email "john#doe.com"
end
factory :admin_user, :parent => :user do
roles { [ FactoryGirl.create(:admin_role) ] }
end
factory :role do
name { "Role_#{rand(9999)}" }
end
factory :admin_role, :parent => :role do
name "Admin"
end
end

Answer 2

Solved
Factory.sequence(:email) {|n| "person#{n}#example.com" }
Factory.define :role do |r|
r.name {"Admin"}
end
Factory.define :role_user do |ru|
ru.association(:role)
ru.association(:user)
end
Factory.define :user do |u|
u.first_name {"matt"}
u.last_name {"jones"}
u.email {Factory.next(:email)}
end
and using it like
let(:role_user) { FactoryGirl.create(:role_user) }
before { sign_in(role_user) }

Answer 3

I was having the exact same problem, with code like:
describe "..." do
let(:user) { create :user }
let(:manager) { create :manager_role }
user.roles << manager
it "should ...." do
# etc.
end
end
# run rspec...
# => `block (2 levels) in <top (required)>': undefined local variable or method `user' for #<Class:0x000001016a2dc0> (NameError)
When I moved the user.roles << manager code into a before(:each) block, the errors disappeared. Thus, something like:
describe "..." do
let(:user) { create :user }
let(:manager) { create :manager_role }
before(:each) do
user.roles << manager
end
it "should ...." do
# etc.
end
end
This saves the pain of having to specify the role <-> user association in your factories.
I'm not familiar enough with how rspec and factory_girl work to understand why you can't have code like user.roles << role immediately after calling let(:user) { create :user }, but putting it into a before(:each) block or into an individual it "should ... " do block should do the trick.
