Rails - Dec 2004 - Question on an error I am getting in ActiveRecord

I have two tables

blogs
blog_categories

blogs:
id
category_id
...

blog_categories:
id
name
...

in my models I have:

class BlogCategory < ActiveRecord::Base
  has_many :blogs, :foreign_key => "category_id"  ### is this
needed?
end

class Blog < ActiveRecord::Base
  belongs_to :blog_category, :foreign_key => "category_id"
end

In my template when I try and reference blog.blog_category.name, I get
the following error:

ActionView::TemplateError (uninitialized constant Blog::BlogCategory) on
line #5 of /blogs/list.rhtml:
2: <% for blog in @blogs %>
3:     <div class="boxContainerLeftColumn">
4:         <div class="entryTitle">
5:             <%= blog.date_added %> - <%= blog.subject %> - <%
if not
blog.blog_category.nil? %><%= link_to(blog.blog_category.name, :action
=> "list", "category_id" => blog.category_id)
%><% end %></div>
6:         <div class="entryPar">
7:         <!-- need just 300 -->
8:         <%= blog.content %>


What am I doing wrong?  The error message is confusing me somewhat. I
tried adding a table_name method to BlogCategory, just in case it
wasn''t
getting that the  table was blog_categories, nothing changed.

I know it''s something stupid I am missing....

Thanks!

You are just missing the "require ''blog_category''"
on the controller.

Just FYI: If I remember correctly, in beta gems (and the next version 
of AR that should be out this week) you don''t need the require 
statements anymore. When you use has_many or any other association 
proc, AR will automagically require the needed class files. Very 
convenient.
