Rails - Mar 2006 - has_many brings back ''uninitialized constant''

hello.  first things first - I am new to ruby on rails (ruby, too), so 
I''m figuring this is just a basic newbie error.

I''m creating a basic photography website.  And I have two tables with a
relationship:

photos:
- id (set up as PK)
- title
- shutter
- aperture
- date
- the_order
...etc

photo_comments:
- id (set up as a PK)
- photos_id (set up as a FK)
- author
- date
- comment
...etc

In my photo.rb model file i have this:
class Photo < ActiveRecord::Base
	has_many :photo_comment
# other code where I use ''find'' to get the photo info
end

This is all I have in my photo_comment.rb model file:
class Photo_comment < ActiveRecord::Base
	belongs_to :Photo
end
>From here I''ll admit I''m a little lost as to how to
procede.  Right now
I''m just wanting to view the comments (i''ll worry about adding
comments
next... but one step at a time).

In my photo_controller.rb file I get the desired photo like this:
@photos = Photo.get_photo(params[:photo])

On the view side for this, I have this line to display the photo:
<img src="/photos/<%= @photos.the_order %>.jpg" />

To get the comments, I''ve been trying to do something like this:

<% for a_comment in @photos.photo_comment %>
	<p><%= a_comment.comment %></p>
<% end %>

However, when I run this code, I get this error:
"uninitialized constant PhotoComment"

Any suggestions on how to fix this, or am I approaching this the wrong 
way and need to do it differently?

Thanks in advance, I appreciate it.

Just scanning quickly: change that to:

   class PhotoComment < ActiveRecord::Base
     belongs_to :photo

and see if that helps :-)

thanks for the reply.  I changed it, but I still get the same error.

Make that plural (:photo_comments).  Another scattershot comment...
sorry I''m being so fragmentary... but maybe that will straighten it
out.

I gave it a try, and I then go this error:
"undefined method `photo_comment''"

The method will be "photo_comments".

Thanks again for the response, but I still get this error:

"uninitialized constant PhotoComment"

I fear I''m out of ideas, based on what you''ve posted.  Where
(i.e., in
what file) does the error seem to happen?

It happens in my photo view.

I''ve zipped up my app folder, thinking it would probably be easier for 
you to take a quick look at that rather than me trying to describe each 
file in a post.

I will do a quick explanation of what I zipped though:

I have two models-> photo.rb and photo_comment.rb, along with 
controllers to each of these.

I have a view for the photo called ''get_info.rhtml''  This is
the file
that is throwing the error.  I have it displaying the info for the photo 
correctly.  It''s when I try to get comments on the photo that the error
occurs.

I''m referencing these two tables:
photos:
- id (set up as PK)
- title
- shutter
- aperture
- date
- the_order
...etc

photo_comments:
- id (set up as a PK)
- photos_id (set up as a FK)
- author
- date
- comment
...etc

Thank you so much for helping me with this, I really appreciate it.

:-)
