Thanks Philip. After reading your response, I tried doing another dummy
application myself, and in the middle of getting everything set up, I
realized that I didn't restart the script/server after adding the
include. So I went back to my other application, and this worked.
Occam's razor :-).
Sorry to hound you with additional questions, but I was wondering if you
had time for one more.
I'm having a hard time limiting the scope of new comments to the Post
model. So, for validates_uniqueness_of :title in the comment.rb model,
that uniqueness would only be attached to the post I'm commenting to,
not globally among all comments in the application.
I tried putting this in comment.rb:
validates_uniqueness_of :title, :scope => :post
but got this error message in my terminal:
