Subject: [OT maybe] ActiveRecord curious behaviour

Hi all,

I appologise if this question is offtopic, hopefully it isn't though...

I have:
   Forum has_many :comments

so obviously, I access the comments collection as
   some_forum.comments

check its type with:
   some_forum.comments.class # => Array

ok, that I expected, so I want to use Array#find on it, right?
   some_forum.comments.find {...}

but oops, I get:
   ActiveRecord::RecordNotFound: Couldn't find Comment without an ID

Hmm, that find is not the find I expected to find ;-) Looks like
an AR#find to me... but on an Array? It's not like I need SQL to
find certain elements of an Array... so I find this behaviour very
interesting. Am I doing something wrong here ? I can find the 
element(s) I want from it, by iterating over it and selecting them, 
but not by using find.

BTW, it's Rails 1.1.6/AR 1.14.4 I'm having this behaviour on, haven't 
tested it on other versions.


Thank you in advance,
Alex
