Displaying 2 results from an estimated 2 matches for "usercomments".
Did you mean:
user_comments

undefined method `model_name' for NilClass:Class
...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?
Thanks!

ActiveRecord: Reference same table twice
Hi,
I have 2 tables, "users", and "user_comments". I am trying to allow
users to leave comments on each other''s profiles (eg, think youtube like

Here is a simplified view of my database schema:
mysql> describe users;
