I am new to Ruby on Rails and have a very simple foreign key example that is driving me nuts. I am using Rails 3 under Windows Vista and have two tables: users and user_comments. user_comments.user_id should point to the user a comment is about.
In my show view for user I have a link to the new method of user_comments to allow a comment to be created. This throws: Showing c:/Gpsappm/app/views/user_comments/_form.html.erb where line #1 raised: undefined method `model_name' for NilClass:Class Extracted source (around line #1): 1: <%= form_for(@user_comment) do |user_comments| %> 2: <% if @user_comment.errors.any? %> 3: <div id="errorExplanation"> 4: <h2><%= pluralize(@user_comment.errors.count, "error") %> prohibited this user comment from being saved:</h2> (1) What exactly does this error message mean? From other posts I gather this is a null instance of UserComments, but this is to create a new instance? (2) What are the step-by-step methods I should follow to debug such issues?
