Note that here you have put @student.user_id > > > If I go like this > > <% @students.each do |student| %> > <% elsif student.user_id == current_user.id %> Also note that her you have said student.user_id (no '@') In the code you posted initially it is @student, which is nil as you have not assigned a value to it.
