I would definitely avoid the duplicate data scenario.

Why does the friends table have profile_id?
If friend_id is pointing to a record in the users table, then there
would be no need to store the profile_id twice.
If friend_id is NOT pointing to a record in the users table, then I
have misunderstood your question and you can ignore the rest of this
post.
If I understand your problem correctly, you need a hasAndBelongsToMany
association which relates the users table to it's self.
Try renaming your friends table to users_friends, and then add this
association to your User model.
var $recursive = 2;
var $hasAndBelongsToMany = array('Friend' =>
array('className'=> 'User',
'joinTable'=> 'users_friends',
'foreignKey' => 'user_id',
'associationForeignKey'=> 'friend_id',
'conditions' => '',
'order'=> '',
'limit'=> '',
'uniq' => true,
'finderQuery' => '',
'deleteQuery' => '',
)
);
if it works correctly (it worked for me when I tested it) you should
find the friend records in the data returned from the User model.
So if your controller code looks like this:
$this->set('user', $this->User->read(null, $id));
Then your view code might look like this:
Friends
hasAndBelongsToMany associations can seem rather complicated if you're
not used to them. If you have trouble getting this code to work, you
should probably read the models chapter of the cake manual, and perhaps
some hasAndBelongsToMany tutorials.
I have seen this question before, but I don't think it was answered, so
please let me know it this works for you.
Good luck,
