Getting undefined method `each` on my controller

I have a method like this :

class ProfilesController < ApplicationController
  before_filter :authenticate_user!

  current_user

  def index
    @users = User.all
  end
  ...
end

and my route is

match 'profile',  :controller => 'profiles', :action => 'index'

but when I access http://127.0.0.1:8080/profile I get:

NoMethodError in Profiles#index undefined method each for nil:NilClass

This means User.all is returning nil. You need to check if there are any users before calling each on them. If you changed your view to look like this it would not raise the error.

<% if @users %>          
  <% @users.each do |user| %>
    ...
  <% end %>
<% end %>
