you have method in helper:
def current_user @current_user ||= user.find(session[:user_id]) end so in templates should utilize current_user rather @current_user
so, should be:
<body> <% if current_user %> hello <%= current_user.username %> <% end %> <%= yield %> </body> update:
but it's improve create method in applicationcontroller:
def current_user @current_user ||= user.find(session[:user_id]) if session[:user_id] end helper_method :current_user because in case current_user can called controllers , templates well.
