Good observation! I had somehow missed the missing backtick ...
another thing for which I don't understand ... I know it _has_ to be
something subtle, but I just can't get my finger on it ...
Anyway, here are the model classes (I have just removed some of the
option keys from the auto-generated stuff):
user.php:
<?php
class User extends AppModel {
var $name = 'User';
var $validate = array(
'login' => array('alphanumeric'),
'points' => array('numeric')
);
var $hasMany = 'Bid';
var $hasAndBelongsToMany = array(
'BidSession' => array('joinTable' =>
'bid_session_registrations')
);
}
?>
bid_session.php
<?php
class BidSession extends AppModel {
var $name = 'BidSession';
var $validate = array(
'title' => array('alphanumeric'),
'cap' => array('numeric')//,
//'starts_at' => array('date'),
//'ends_at' => array('date')
);
var $hasMany = 'Bid';
var $hasAndBelongsToMany = array(
'User' => array('joinTable' => 'bid_session_registrations')
);
}
?>
bid.php
<?php
class Bid extends AppModel {
var $name = 'Bid';
var $validate = array(
'bid_points' => array('numeric')
);
var $belongsTo = array('User', 'BidSession');
}
?>
It doesn't help even if I specify the 'foreignKey' and
'associationForeignKey' in the HABTM relationship.
As a quick-and-dirty debug, I put the line
pr($query);
in Model::find() [CORE\cake\libs\model\model.php] just before the call
to $db->read($this, $query); on line 1795. This is what I get (url: /
users/add):
Array
(
[conditions] =>
[fields] => Array
(
[0] => BidSessionRegistration.user_id
[1] => BidSessionRegistration.
)
[joins] => Array
(
)
[limit] =>
[offset] =>
[order] => Array
(
[0] =>
)
[page] => 1
[group] =>
[callbacks] => 1
[recursive] => -1
[list] => Array
(
[groupPath] =>
[valuePath] => {n}.BidSessionRegistration.
[keyPath] => {n}.BidSessionRegistration.user_id
)
)
In the docs for Model::find() it's written that:
* Specifying 'fields' for new-notation 'list':
* - If no fields are specified, then 'id' is used for key and 'model-
>displayField' is used for value.
* - If a single field is specified, 'id' is used for key and
specified field is used for value.
* - If three fields are specified, they are used (in order) for key,
value and group.
* - Otherwise, first and second fields are used for key and value.
So I modified the auto-generated $this->User->BidSessionRegistration-
>find('list') call in users_controller.php by explicitly specifying
the fields as array('bid_session_id', 'user_id') ... still, no
improvement.
Now I changed the bid_session_registrations table by removing PK
(bid_session_id, user_id) and adding an id field (although I guess
there's no need to do that for join tables that are not separately
modeled...). Now, the debug output reads:
Array
(
[conditions] =>
[fields] => Array
(
[0] => BidSessionRegistration.id
[1] => BidSessionRegistration.id
)
.
.
.
[list] => Array
(
[groupPath] =>
[valuePath] => {n}.BidSessionRegistration.id
[keyPath] => {n}.BidSessionRegistration.id
)
)
But this is not what I want...
Also, I have no clue why the bake script related User to
BidSessionRegistration not BidSession in /user/add...
Sorry for the long post, but I am really confused why things are
happening the way they are. Thanks for all the help!
