Ensure all non 200 response code pages (404 and 500) - rotati/wiki GitHub Wiki

Create a errors response page

1. create a controller called any thing you prefer in our case we call errors_controller.rb

```
  class ErrorsController < ApplicationController
    before_action :switch_tenant
    layout 'purchaser'

    def not_found
      render(status: 404)
    end

    def internal_server_error
      render(status: 500)
    end
  end
```

2. got to routes.rb create two routes for handling the errors

```
  match "/404", :to => "errors#not_found", :via => :all
  match "/500", :to => "errors#internal_server_error", :via => :all
```
* NOTE: check the environment if you want to error to run only for `production`

 ```
   unless Rails.env.development?
     match "/404", :to => "errors#not_found", :via => :all
     match "/500", :to => "errors#internal_server_error", :via => :all
   end
 ```

3. last but not least goto views create a directory called errors * in errors directory, create two files
   • not_found.haml

     .row
       .col-xs-12.content
         .title.text-center
           %h1 404
           %h1 We've had a facelift!
       .intro.text-center
         %p The page you are looking for may have been removed or redirected to a new location.
       .intro.text-center
        %p
          Visit our home page at
          = succeed "." do
            %a{:href => "/"}
              Your Company Name
   

   • internal_server_error.haml

     .row
       .col-xs-12.content

           %h1 We are sorry, but something went wrong at our end!
