Rails, Devise - Admin trying to edit another user

问题:

Being fairly new in developing with Rails, I'm trying to get my head around the following: I'm working with a Devise + Cancan + olify app to try and create authentication and user management. I've the general user behaviour sorted and I'm trying to achieve for an admin user to be able to edit another user profile.

At the moment, the admin user is able to list users and try to edit other user's profile. However, when going on the edit page, despite the URL/route being correct to me, I'm still being presented with the "currentuser"/admin information in the form.

So in short, the scenario: UserId1 is an admin UserId1 is trying to edit the profile of UserId2

Logged as UserId1, the following route bring details for UserId1 instead of UserId2: http://localhost:3000/d/users/edit.2

Here is the routes.rb:

devise_for :users, :path_prefix => 'd', :controllers => { :registrations => 'registrations' }

namespace :admin do
  get '', to: 'dashboard#index', as: '/'
  resources :users
end

Here is the users#index view:

<table>
  <tbody>
    <% @users.each do |user| %>
      <tr>
        <td><%= user.id %></td>
        <td><%= user.first_name %></td>
        <td><%= user.last_name %></td>
        <td><%= user.email %></td>
        <td>
          <%= link_to edit_user_registration_path(user) %>
        </td>
        <td>
          <%= link_to registration_path(user),class: "red", :data => { :confirm => "Are you sure?" }, :method => :delete %>
        </td>
      </tr>
    <% end %>
  </tbody>
</table>

Here is the users_controller.rb:

class Admin::UsersController < ApplicationController
  def index
    @users = User.all
  end
end

Any help is appreciated!

rake routes gives me the following:

回答1:

<%= link_to edit_user_registration_path(user) %>

Is still pointing to your devise route, it should be:

<%= link_to edit_admin_user_path(user) %>

Which is described in rake routes.

回答2:

You problem stems from the fact that the route should end with edit/2 instead of edit.2. The .2 makes Rails think that you are trying to access a page with a file extension of 2 instead of the user edit page for the user with an id of 2.

Try running rake routes and check to see what routes are listed there and if any of them match the route you are trying to use.
