Hi all,

I am learning the Model relationship types in cakephp.
I have built twotables and in one of the Table A,
I got these fields in it:

Table A {postID, topic, content} 
Table B {replyID, content, postID}

And when I ran the web page, a bunch of error related to SQL
popped up saying that cakephp couldn't find post_id.

It is weird that I have already declared
the $primaryKey to be using postID in the tableA.php under Models folder,
but cakephp seemed want me to change the ID field to post_id instead of postID, because the error disappeared after I have changed the primaryKey to post_id.

ANy ideas?
