Factory Girl rspec issue: has_many through factory - ruby-on-rails

Question

I am having an issue regarding Factory Girl in Rails. I currently have pundit setup am trying to test my user policies yet the factory does not seem to work when in rspec.
Inside the rails console, I can load up the console and type:
user=FactoryGirl.create(:admin_user)
r=user.roles
This works correctly creates a user and the correct associations between a user and a role. However, when the factory is used in rspec- A user is created but not the associated assignment. (I discovered this by using 'pp' inside the specific tests.)
I do not need to create a role, since the roles are set so I am looking them up.
Any ideas?
Models
class User < ApplicationRecord
has_many :assignments, dependent: :destroy
has_many :roles, through: :assignments, dependent: :destroy
def has_role?(roles)
roles.each do |role|
if self.roles.include? role
return true
end
end
false
end
class Role < ApplicationRecord
# Associations
has_many :assignments
has_many :users, through: :assignments
class Assignment < ApplicationRecord
# Associations
belongs_to :user
belongs_to :role
Factories
FactoryGirl.define do
factory :user do
first_name {Faker::Name.first_name}
last_name {Faker::Name.last_name}
email {Faker::Internet.email}
password {Faker::Internet.password(8)}
factory :admin_user do
after(:create) do |user|
Assignment.create(user: user , role: Role.find_by(label:'System Admin') )
end
end
end
end
Tests
User Policy Test
describe UserPolicy do
subject { UserPolicy }
let (:current_user) { FactoryGirl.build_stubbed :user}
let (:other_user) { FactoryGirl.build_stubbed :user }
let (:admin) { FactoryGirl.build_stubbed :admin_user}
permissions :index? do
it "denies access if not an admin" do
expect(UserPolicy).not_to permit(current_user)
end
it "allows access for an admin" do
expect(UserPolicy).to permit(admin)
end
end
end
Other Test With same Issue
feature 'User index page', :devise do
after(:each) do
Warden.test_reset!
end
scenario 'user sees own email address' do
user = FactoryGirl.create(:admin_user)
expect(user.has_role?(Role.where(label: 'System Admin'))).to eq true
login_as(user, scope: :user)
visit users_path
expect(page).to have_content user.email
end
end
This test fails since the user has no role assigned.
Controller
class AssignmentsController < ApplicationController
def create
#assignment = Assignment.new(assignment_params)
if #assignment.save
redirect_to users_path(), :notice => "Role Added"
else
flash[:alert]="Unable to Add Role"
end
end
