I'm trying to make an example of a small networking site, and when I log in a user, it should redirect and show his profile, but I get the following error:

NoMethodError in User#index

Showing app/views/user/index.html.erb where line #5 raised:

undefined method `screen_name' for nil:NilClass Extracted source (around line #5):

2: Your basic information 3: 4:

    5:
  • Screen name: <%= @user.screen_name %>
    • 6:
  • Email: <%= @user.email %>
    • 7:
  • Password: **********
    • 8:

Thanks a lot in advance!

Your @user object is "nil". You need to make sure that you set @user, e.g. via a "before_filter".
