cakephp hasAndBelongsToMany - cakephp

Question

My 'Reservation' model and 'Profile' model have hasAndBelongsToMany association.
Here is my Reservation Model.
class Reservation extends AppModel {
.
.
var $hasAndBelongsToMany = array(
'Profile' => array(
'className' => 'Profile',
'joinTable' => 'profiles_reservations',
'foreignKey' => 'reservation_id',
'associationForeignKey' => 'profile_id',
'unique' => true,
)
);
And Here is my Profile Model.
class Profile extends AppModel {
var $name = 'Profile';
}
And here is my controller .
function prac3($lname, $fname) {
$profiles = $this->Profile->find('all', array(
'conditions' => array(
'Profile.lname LIKE' => $lname.'%',
'Profile.fname LIKE' => '%'.$fname.'%'
),
'order'=>array( 'Profile.created DESC' ),
));
$this->set('profiles', $profiles);
}
And here is my view.
<?php
if($profiles) {
foreach($profiles as $key => $profile): ?>
<tr>
<td><?= $profile['Profile']['id'] ?></td>
<td><?= $profile['Profile']['lname'] ?></td>
<td><?= $profile['Profile']['fname'] ?></td>
<td><?= $profile['Profile']['home_phone'] ?></td>
</tr>
endforeach;
echo '</table>';
}
?>
I wanna get ['Reservation']['name'] in the view using Profile model. How can I do this?

Answer 1

Update Your Profile class
class Profile extends AppModel {
var $name = 'Profile';
var $hasAndBelongsToMany = array(
'Reservation' => array(
'className' => 'Reservation',
'joinTable' => 'profiles_reservations',
'foreignKey' => 'profile_id',
'associationForeignKey' => 'reservation_id',
'unique' => true, // More about update below
)
}
In Your find() method shoud use recursive:
$profiles = $this->Profile->find('all', array(
//...
'recursive' => 2,
));
or Containable behavior:
$this->Profile->Behaviors->load('Containable');
$profiles = $this->Profile->find('all', array(
//...
'contain' => array(
'Reservation',
),
'recursive' => -1,
));
and Your reservetion will be in array like $profiles['Reservation'][n]['name'].
Additional, in Your comment You wrote "When I add new reservation and profile, the rows that has the profile id were disappeared in the profiles_reservations Table."
Because You are using 'unique' => true in $hasAndBelongsToMany property. The cookbook says:
If true (default value) CakePHP will first delete existing relationship records in the foreign keys table before inserting new ones. Existing associations need to be passed again when updating.

Answer 2

Try this
class ReservationsTable extends Table
{
public function initialize(array $config)
{
$this->belongsToMany('Profiles', [
'joinTable' => 'reservation_profiles',
]);
}
}
class ProfilesTable extends Table
{
public function initialize(array $config)
{
$this->belongsToMany('Reservations', [
'joinTable' => 'reservation_profiles',
]);
}
}
Then as you can see ReservationsTable is the model that relate Reservation to Profiles using reservation_profiles table to do that Profiles does the same. You don't need to have a model for reservation_profiles, but you must have this table on your databse, I sugest you to use migration to create them. Finally in your controller, this could be in your ReservationController you call
$this->Reservation->Profiles->find()->where(['condition'=> 'param']);
This may solve your problem, explainning ($this) refer to the Controller class, ->REservation refer to the model Reservation -> Profiles refer to related model to the class Reservation model, ->find()... refer to the query executed.
