Question

I’m building an admin control panel (attempting to 😉 ).

I have been looking at Backend administration in Ruby on Rails and as suggested I am trying to make Admin::AdminController that checks for admin and sets the layout etc.

But I’m also trying to set a route in it that routes /admin to /admin/dash

From my understanding of reading http://guides.rubyonrails.org/routing.html#controller-namespaces-and-routing , specifically section 2.6,

Admin::AdminController

tells rails that Admin is the name space, AdminController is the controller which is a subclass (extension?, implementation of the interface?) of ApplicationController. Which would imply the controller should live in app/controllers/admin/ and be called admin_controller.rb.

But what I want is

AdminController

I get errors like:

uninitialized constant Admin::Controller

My code for the route:

  match :admin, :to => 'admin/admin#dash'
  namespace :admin do
    # Directs to /admin/resources/*
    match '/dash', to: '#dash'
    resources :users, :pictures
  end

I have put the controller in app/controllers/admin, app/controllers and the combinations with

class Admin::AdminController < ApplicationController
  before_filter :admin_user
  # / ** STATIC ADMIN PAGES ** /
  def dash
  end
end

or class AdminController < ApplicationController.

Edit: Maybe it’s my understanding of routing.
Example:

namespace :admin do
  get "/dash"

vs.

namespace :admin do
  match "/dash" to "admin#dash"

vs.

namespace...
  match "/dash" to "#dash"

The first one makes it so i can display a dash via the controller, i.e. admin/dash would be controlled by

AdminController < ApplicationControler
  def dash
  end

Does the second one route admin/admin/dash to admin/dash?

TL/DR:
I think my confusion comes from syntax or my poor understanding of RESTful practices or maybe even class / object inheritance in ruby.

Thanks for helping this n00b out. 🙂

Side question: can I change my code to be minimized until someone opens it like a spoiler so it doesn’t crowd things up if I find more information and add it?

Answer 1

I think your initial approach was correct, but you need to change it a little.

1) insert the /admin => /admin/dash inside the namespace (imho, its better to redirect it)

match 'admin' => redirect('admin/dash')

or

namespace :admin do
  match '/', to: 'admin#dash'
end

2) You can’t match ‘/dash’ to ‘#dash’ since you’re not inside a resource block, you’re inside a namespace block, so it doesnt’ have implied controller.

namespace :admin do
  match 'dash', to: 'admin#dash'
  # This will go to Admin::AdminController#dash
  # (first Admin because of the namespace,
  #  and the second because of the controller name)
end

hope it works 😀
