Routing Error No route matches {:action=>"show", :controller=>"dashboard"}
I want that when Admin sign in ,he should be redirected to "dashboard" page and if a normal user sign in, they should be redirected root of application which is "posts#index". When normal user sign up, it works perfectly means it takes users to root path of application. But when Admin log in, it shows "Routing Error No route matches {:action=>"show", :controller=>"dashboard"} " error. I have add is_Admin column in User table for Admin.
ApplicationController.rb
class ApplicationController < ActionController::Base
protect_from_forgery
def after_sign_in_path_for(user)
if current_user.is_Admin?
redirect_to dashboard_path
else
:root
end
end
end
Dashboard_controller.rb
class DashboardController < ApplicationController
def index
@users = User.all
end
end
views/dashboard/index.html.erb
<h2>Admin Area</h2>
<table>
<tr>
<th> User Email </th>
<th> User Registered Time</th>
<th> Login Count</th>
</tr>
<% @users.each do |user| %>
<tr>
<td><%= user.email %></td>
<td><%= user.created_at %></td>
<td><%= user. sign_in_count %></td>
</tr>
<% end %>
</table>
routes.rb
Infra::Application.routes.draw do
devise_for :users
resources :posts
root :to => "posts#index"
#match "dashboard" => "dashboard#index"
resources :dashboard
end
rake routes output is below:

I have defined "def after_sign_in_path_for(user)" in application_controller.rb which decide where to redirect on basis of type of user. I think, problem is here.

Use this to get it working:
redirect_to main_app.root_path
add the main_app to your route path

Method after_sign_in_path_for should return path, not redirect.
class ApplicationController < ActionController::Base
protect_from_forgery
def after_sign_in_path_for(user)
if current_user.is_Admin?
dashboard_index_path
else
:root
end
end
end

1) - anytime you change routes, you should probably restart the rails process
then I would try using match in-place of resources for a dashboard (guessing you don't need all of the CRUD actions?)
match "dashboard" => "dashboard#index"
redirection should be
redirect_to dashboard_path
if you do use resources, it would be redirect_to dashboards_path (plural for the index action)
the order of routes is also important, maybe put your match closer to the top of the routes?
