How to fix this up? " Unknown action The action 'index' could not be found for UsersController"

When开发者_开发百科 I go to my localhost:3000/users page, I get:

Unknown action

The action 'index' could not be found for UsersController.

If you were following Hartl's tutorial,then accessing localhost:3000/users will cause this error. Try localhost:3000/signup instead.

You need not define the default actions (assuming appropriate http method), all you need to do is add the following to your config/routes.rb

resources :users

First you need to make sure that your controller actually has an index action, so

class UsersController < ApplicationController has to include the def index ... end in it. Also, make sure your routes are set up correctly using

resources :users

and check it by typing

rake routes

in the terminal to check that the routes are right. You might also want to check that the root is set up correctly in the config/routes.rb file

if you got the same problem with me (I cant access the localhost:3000/users but I can access my localhost:3000/signup), it might be works for u.
First, in your users_controller.rb (Controller for Users) , add

def index 
end

Then , make a file "index/html/erb" in your app/views/users/index.html.erb and put this code

<% controller.redirect_to "/signup" %>

You might have to rerun your server, and it works on my problem.

Remember, if you've included

get 'signup'  => 'users#new 
resources :users

…in your routes.rb file, then you need to use localhost:3000/signup instead. I believe if you removed get 'signup' => 'users#new and left only resources :users then using localhost:3000/users would take you to the new user signup form.

Remove the debugger line. Also, make sure you have exit the rails console.

class UsersController < ApplicationController
  def show
    @user = User.find(params[:id])
    debugger
  end

  def new
  end
end
