No Route Matches ... Rails Engine - ruby-on-rails

Question

So I keep getting the error:
No route matches {:action=>"create", :controller=>"xaaron/api_keys"}
Which is thrown in the test:
it "should not create an api key for those not logged in" do
post :create
expect(response).to redirect_to xaaron.login_path
end
when I go to spec/dummy and run the rake routes command I see:
api_keys GET /api_keys(.:format) xaaron/api_keys#index
POST /api_keys(.:format) xaaron/api_keys#create
new_api_key GET /api_keys/new(.:format) xaaron/api_keys#new
edit_api_key GET /api_keys/:id/edit(.:format) xaaron/api_keys#edit
api_key GET /api_keys/:id(.:format) xaaron/api_keys#show
PATCH /api_keys/:id(.:format) xaaron/api_keys#update
PUT /api_keys/:id(.:format) xaaron/api_keys#update
DELETE /api_keys/:id(.:format) xaaron/api_keys#destroy
Which shows that yes this route does exist. My routes file for this engine looks like:
Xaaron::Engine.routes.draw do
get 'login' => 'sessions#new', :as => 'login'
get 'logout' => 'sessions#destroy', :as => 'logout'
get 'signup' => 'users#new', :as => 'signup'
get 'permission_denied' => 'error#denied', :as => 'permission_denied'
get 'record_not_found' => 'error#error', :as => 'record_not_found'
get 'password_reset' => 'password_resets#edit', :as => 'rest_user_password'
resource :error, controller: 'error'
resources :users
resources :api_keys
resources :sessions
resources :roles
resources :password_resets
end
What am I missing?
update
For those of you curious how I am getting these routes, its because the dummy app's routes file is set up (by default) as such:
Rails.application.routes.draw do
mount Xaaron::Engine => "/xaaron"
end
Update II
I have been reading this api docs on how routing is done in engines and I believe the way I have done this is correct, how ever the controller is defined as such:
module Xaaron
class ApiKeysController < ActionController::Base
before_action :authenticate_user!
def index
#api_key = Xaaron::ApiKey.where(:user_id => current_user.id)
end
def create
#api_key = Xaaron::ApiKey.new(:user_id => current_user.id, :api_key => SecureRandom.hex(16))
create_api_key(#api_key)
end
def destroy
Xaaron::ApiKey.find(params[:id]).destroy
flash[:notice] = 'Api Key has been deleted.'
redirect_to xarron.api_keys_path
end
end
end

You need to tell your spec you are using the engine routes:
describe ApiKeysController do
routes { Xaaron::Engine.routes }
it "should not create an api key for those not logged in" do
post :create
expect(response).to redirect_to xaaron.login_path
end
end
