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:
To get the comments, I’ve been trying to do something like this:
<% for a_comment in @photos.photo_comment %>
<%= a_comment.comment %>
<% 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’”

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.

In my first response I said:

and I still say that You’ve still got Photo_comment.
