Question

I am using devise and cancan in my app. Both are working.

I have a User model and I have just added (using scaffolding) a new model called Purchase.

Before the Purchase model was added i also have a dashboard controller (which just shows a single page at the moment, dashboard#show) and is the page that gets loaded after login at localhost:3000/dashboard

When a user is not logged in, i can access localhost:3000/purchases. But when the user is logged in I cannot. I can access purchase/1 but not /purchases.

Any idea what is going on here? The error it gives me is

“No route matches {:action=>”show”, :controller=>”dashboard”}”

Dashboard Controller

class DashboardController < ApplicationController
    def show
        @user = User.find(params[:id])
        authorize! :read, @user
    end

end

Routes.rb

App::Application.routes.draw do
  root :to => 'static_pages#index'
  match '/about', :to => 'static_pages#about'
  match '/error', :to => 'static_pages#error'
  devise_for :users

  resources :users

  resources :dashboard

  resource :visitors, :only => :create # POST to visitor_path to create a visitor

  resources :purchases

Singular must be resource, else resources

resource :dashboard
resource :visitor, :only => :create

or

resources :dashboards

depending in what the task is
