Rolify with Rails fixtures

Below are two ways of getting rolify to work with rails fixtures. Explaining Rails fixtures is outside the scope of this wiki. For more information please see rails fixture documentation.

Method 1: The following solution works for Rails 4.2 and assumes roles are attached to a User model. To get rolify working with Rails fixtures:

Create a UsersRole model in models/users_role.rb

# pretty much exclusively created for our fixtures to work
class UsersRole < ActiveRecord::Base
  belongs_to :user
  belongs_to :role
end

Create fixtures like so:

# users.yml
some_user:

# roles.yml - key here is to NOT include "resource" 
admin_role:
  name: :admin

# users_roles.yml
users_roles1:
  user: some_user
  role: admin

Add the fixtures to your tests

# in some test file
fixtures :users, :roles, :users_roles

users(:some_user).has_role? :admin # => true

---

Method 2: If you feel nervous about adding a rails model strictly for supporting fixtures there is an alternative solution. The key here is to not define users in roles.yml fixtures since doing so will prevent attributes from being set correctly.

example:

# roles.yml
first_dealership_admin_role:
  name: :dealership_admin
  resource_id: 1
  resource_type: 'Dealership'

# users.yml
dealership_admin:
  id: 4
  email: '[email protected]'
  encrypted_password: <%= Devise::Encryptor.digest(User, 'password') %>
  dealership_id: 1
  roles: first_dealership_admin_role

# dealerships.yml
one:
  id: 1
  name: dealership_name
