Routing troubles with custom admin-view

[Simon Prückl]

Hey there,

I'm having some troubles with my routes and hope, somebody can help me.

In my shop I need some additional configuration pages in the backend.

For example, I would like to be able to manage something called "Ingredient".

I've created: 

• Ingredients in the database, the table is called "ingredients"
  
• A model called Ingredient, located in app/model/spree/ingredient.rb.
  
• Views for showing, editing and deleting ingredients.
  
• A deface to add the link to the configurations_menu in the admin view.
  
• The routes for the resource admin

No, when I try to load any admin page, I get this error:

undefined method `admin_ingredients_path' for #<ActionDispatch::Routing::RoutesProxy:0x007f85e8dc35a0>

My routes.rb:

Rails::application.routes.draw do  
  mount Spree::Core::Engine, :at => '/'
  namespace :admin do

    resources :ingredients
   end
end

The routes that are created:

simon@Ubuntu-1404-trusty-64-minimal:~/spiceshop$ rake routes | grep ingred
    admin_ingredients GET    /admin/ingredients(.:format)          admin/ingredients#index
                      POST   /admin/ingredients(.:format)          admin/ingredients#create
 new_admin_ingredient GET    /admin/ingredients/new(.:format)      admin/ingredients#new
edit_admin_ingredient GET    /admin/ingredients/:id/edit(.:format) admin/ingredients#edit
     admin_ingredient GET    /admin/ingredients/:id(.:format)      admin/ingredients#show
                      PATCH  /admin/ingredients/:id(.:format)      admin/ingredients#update
                      PUT    /admin/ingredients/:id(.:format)      admin/ingredients#update
                      DELETE /admin/ingredients/:id(.:format)      admin/ingredients#destroy

The deface:

Deface::Override.new(virtual_path:  "spree/admin/shared/sub_menu/_configuration",
                     name:          "ingredients_admin_configurations_menu",
                     insert_bottom: "[data-hook='admin_configurations_sidebar_menu'], #admin_configurations_sidebar_menu[data-hook]",
                     text:          "<%= configurations_sidebar_menu_item Spree.t(:ingredients), spree.admin_ingredients_path %>",
                     disabled:      false)

When I played with my routes.rb I got it working for a minute, but when I had to restart the web server, I had no more routes at all...

But I think that shows, that database, model, controller and views are working.

I think it has to do something with the routes.rb, whether it says Rails::application.routes.draw or Spree::something

Any help appreciated, thank you!

I thought I solved it by changing routes.rb to:

Rails::application.routes.draw do
  mount Spree::Core::Engine, :at => '/'

  Spree::Core::Engine.routes.prepend do

    namespace :admin do
      resources :ingredients
    end
  end

end

But that only works until the next server-restart, then I have to comment out the line

 Spree::Core::Engine.routes.prepend do

to start the server, after starting I can uncomment it again and the link in the configuration menu is working again...

Simon, can you try this?


Rails::application.routes.draw do
  mount Spree::Core::Engine, :at => '/'



  Spree::Core::Engine.routes.draw do



    namespace :admin do
      resources :ingredients
    end
  end
end

Awesome, that tiny little changed solved it.

Thank you Mohammed!

What is the difference between draw and prepent? Is there any perf impact?
