Question

I have this simple code in my user_controller.rb file

  #listing all users
  def index
    @users = User.all # getting all the users!
  end

and the view folder i got this:

<!-- View for index action in user's controleer -->
<h1>All users</h1>

<ul class="users">
  <% @users.each do |user| %>
    <li>
      <%= link_to user.name, user %>
    </li>
  <% end %>
</ul>

The User.all.count returns 13.

Now the code is simple. Why do i get this error?

NoMethodError in Users#index 
undefined method `each' for nil:NilClass

Answer 1

Refactor your user_controller.rb to users_controller.rb.

You are calling the wrong controller with the wrong view !
