how to view the page through the admin panel?

please help solve the problem.

a resource documents and the appropriate controller:

class DocumentsController < ApplicationController

  def index
    @documents = Document.all.paginate(page: params[:page], per_page: 10)
  end

  def admin_index
    @documents = Document.all.paginate(page: params[:page], per_page: 10)
    render layout: "admin" 
  end  

  def show
    @document = Document.find(params[:id])
  end

  def admin_show
    @document = Document.find(params[:id])
    render layout: "admin" 
  end  

  ....
  ....
end

a 2 layouts: 

application.html.erb, 
admin.html.erb

the controller index lists the documents in the public section (application.html.erb). admin_index controller displays a list of documents in the closed part of the site (admin.html.erb).

in the public part of the site I can look any document by clicking on 'show':

<% @documents.each do |document| %>
    <%= document.title %>
    <%= link_to 'Show', document %>
<% end %>

The problem is that in a closed part of the site I did not get to see any document by clicking the link below:

<%= link_to 'Show', document %>

a problem that throws me a page of a particular document, but the layout: application.html.erb, and I need a layout: admin.html.erb

routes:

Testpager::Application.routes.draw do
  get "admin/index"
  resources :news, only: [:index, :show]

  resources :documents, only: [:index, :show, :destroy]

  get "contacts/index"
  get "services/index"
  get "index/index"
  get "admin/index"
  get "admin/documents" => 'documents#admin_index'
  get "admin/documents/:id" => 'documents#admin_show'

  root 'index#index'
end

First of all, there's no difference in the link you've created with the link_to helper in your index.html.erb and admin_index.html.erb, so let's address that first.

Change your admin_show route in your routes.rb to:

get 'admin/documents/:id', to: 'documents#admin_show', as: 'admin_document'

Now change the link_to in your admin_index.html.erb to this:

<%= link_to 'Show', admin_document_path(document) %>

That should do it.

Side note

The way you've set up the 'public' and 'admin' parts of your site seem odd. I would personally create an admin namespace and a separate DocumentsController in that namespace. You'll have to change your routes.rb, create an admin controller, view and layout if you want this.

Add the documents resource to the admin namespace instead of the admin routes you've already added:

...

namespace :admin do
  resources :documents, only: [:index, :show, :destroy]
end

resources :documents, only: [:index, :show, :destroy]

...

Create a app/controllers/admin/documents_controller.rb file and move the admin_* methods from your original controller to that one and also move the admin_*.html.erb views to app/views/admin/*.html.erb.

Now, last but not least move your app/views/layouts/admin.html.erb file to app/views/layouts/admin/application.html.erb. That should do it.

Note that you've got to use a module in your admin controller:

module Admin
  class DocumentsController < ApplicationController
    ...
  end
end
