rolify with fixtures

rolify_with_fixtures.md

I'm using rails 4.2 and had a tough time with rolify and rails fixtures. After some mucking I finally got it working. Posting here incase someone else needs to do something similar.

1. 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

2. 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

3. Add the fixtures to your tests

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

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