The controller is the "home" controller and looks like this (very basic):
class HomeController < ApplicationController def index end end The view for the home controller is is just a basic home page and I just wanted to render a login partial there since I'm also planning to use it elsewhere in the app. I assumed that there is no user_session, since a user is not logged in at this point. So, I didn't think I would need to pass it anything. I can hit http://mysite/lgoin without passing any instance variables and it shows the partial properly. Here's a trace: Showing app/views/user_sessions/_user_session.html.erb where line #1 raised: Called id for nil, which would mistakenly be 4 -- if you really wanted the id of nil, use object_id Extracted source (around line #1): 1: <% form_for @user_session, :url => user_session_path do |f| %> 2: <%= f.error_messages %> 3: <%= f.label :email %><br /> 4: <%= f.text_field :email %><br /> Trace of template inclusion: app/views/home/index.html.erb RAILS_ROOT: c:/wwwroot/ror/blostm Application Trace | Framework Trace | Full Trace C:/ruby/lib/ruby/gems/1.8/gems/actionpack-2.3.4/lib/action_controller/ record_identifier.rb:76:in `dom_id' C:/ruby/lib/ruby/gems/1.8/gems/actionpack-2.3.4/lib/action_view/ helpers/record_identification_helper.rb:16:in `dom_id' C:/ruby/lib/ruby/gems/1.8/gems/actionpack-2.3.4/lib/action_view/ helpers/form_helper.rb:293:in `apply_form_for_options!'
