Question

I have three Models with the associated properties:

Links Model:

var $belongsTo = array('LinkCategory');

LinkCategory Model:

var $hasMany = array('Link');
var $hasAndBelongsToMany = array('User');

User Model

var $hasAndBelongsToMany = array('LinkCategory');

With that, I would expect the following to get me all the link categories for the user.

$user_link_categories = $this->LinkCategory->find('all', array('conditions' => array('User.id' => 1)));

However, it dies with:
Unknown column ‘User.id’ in ‘where clause’
Query: SELECT LinkCategory.id, LinkCategory.title, LinkCategory.created, LinkCategory.modified FROM link_categories AS LinkCategory WHERE User.id = 1

I am new to CakePHP, but not MVC. In my mind, this should work given my associations. Have I missed something or does this just not work in CakePHP for some reason.

I have three Models with the associated properties:

Links Model:

There should be Link model, not Links. I hope that was a misprint.

LinkCategory Model:

…

var $hasAndBelongsToMany = array(‘User’);

I guess that means that you have join table link_categories_users and therefore you need to change recursive value to 2:

$user_link_categories = $this->LinkCategory->find('all', array('recursive' => 2, 'conditions' => array('User.id' => 1)));

Or:

$user_link_categories = $this->LinkCategory->find('all', array('recursive' => 2, 'conditions' => array('LinkCategoryUser.user_id' => 1)));

Or:

$user = $this->User->find('first', array('recursive' => 2, 'conditions' => array('User.id' => 1)));

Update. This must work:

$user_link_categories = $this->LinkCategory->User->find('all', array('conditions' => array('User.id' => 1)));
