So I'm working with authlogic, and I'm trying to duplicate the login functionality to the welcome page, so that you can log in by restful url or by just going to the main page. No, I don't know if we'll keep that feature, but I want to test it out anyway. Here's the error message:
RuntimeError in Welcome#index
Called id for nil, which would mistakenly be 4 -- if you really wanted the id of nil, use object_id
The code is below. Basically, what's happening is the index view (the first code snippet) is sending the information from the form to the create method of user_sessions controller. At this point, in theory, it create should just pick up, but it doesn't.
PLEASE help. Please. I've been doing this for about 8 hours. I checked Google. I checked IRC. I checked every book I could find. You don't even have to answer, I can to the grunt work if you just point me in the right direction.
<% form_for @user_session, :url => user_sessions_path do |f| %>
<%= f.text_field :email %><br />
<%= f.password_field :password %>
<%= submit_tag 'Login' %>
<% end %>
class ApplicationController < ActionController::Base
helper :all # include all helpers, all the time
protect_from_forgery # See ActionController::RequestForgeryProtection for details
# Scrub sensitive parameters from your log
# filter_parameter_logging :password
helper_method :current_user_session, :current_user
before_filter :new_session_object
protected
def new_session_object
unless current_user
@user_session = UserSession.new(params[:user_session])
end
end
private
def current_user_session
return @current_user_session if defined?(@current_user_session)
@current_user_session = UserSession.find
end
def current_user
return @current_user if defined?(@current_user)
@current_user = current_user_session && current_user_session.record
end
end
