I need the username not the user_id. How can i set the association between Users.User model and Comment model and with Post model.

So far i have this in Comment model public $belongsTo = array('Post','Users.User');

Can anyone please explain with example about this association?

Answer 1

the field user_id is a foreign key in that table.

Cake will automatically fetch records related to that id, including username and other fields depending on your recursive level.
