Hi, I am relatively new to
CakePHP, I am doing fine with the documentation, but I've been trying to find a way out to this problem for weeks and I don't seem to find the solution, I am sure it is easy and maybe even automagicaly doable, but I just don't know how to find it (maybe I don't know the jargon for these kind of things)
My model structure is like this:
<?php
class Trip extends AppModel {
var $belongsTo = array(
'User' => array(
'className' => 'User',
'foreignKey' => 'user_id'
),
'Start' => array(
'className' => 'Place',
'foreignKey' => 'start_id'
),
'End' => array(
'className' => 'Place',
'foreignKey' => 'end_id'
),
'Transport' => array(
'className' => 'Transport',
'foreignKey' => 'transport_id'
)
);
}
?>
<?php
class Place extends AppModel {
var $belongsTo = array(
'User' => array(
'className' => 'User',
'foreignKey' => 'user_id'
),
'Country' => array(
'className' => 'Country',
'foreignKey' => 'country_id'
),
'State' => array(
'className' => 'State',
'foreignKey' => 'state_id'
),
'City' => array(
'className' => 'City',
'foreignKey' => 'city_id'
)
);
var $hasMany = array(
'PlaceStart' => array(
'className' => 'trip',
'foreignKey' => 'start_id',
'dependent' => false
),
'PlaceEnd' => array(
'className' => 'trip',
'foreignKey' => 'end_id',
'dependent' => false
)
);
}
?>
<?php
class State extends AppModel {
var $belongsTo = array(
'Country' => array(
'className' => 'Country',
'foreignKey' => 'country_id',
'conditions' => '',
'fields' => '',
'order' => ''
)
);
var $hasMany = array(
'City' => array(
'className' => 'City',
'foreignKey' => 'city_id',
'dependent' => false
)
);
}
?>
... and so forth with User, City, Country, and Transport Models.
What I am trying to achieve is to get all the information of the whole tree when I search for a Trip.
<?php
class TripController extends AppController {
function index() {
debug($this->Trip->find('first'));
}
}
Outputs
Array
(
[Trip] => Array
(
[id] => 6
[created] => 2010-05-04 00:23:59
[user_id] => 4
[start_id] => 2
[end_id] => 1
[title] => My trip
[transport_id] => 1
)
[User] => Array
(
[id] => 4
[name] => John Doe
[email] =>
[email protected]
)
[Start] => Array
(
[id] => 2
[user_id] => 4
[country_id] => 1
[state_id] => 1
[city_id] => 1
[direccion] => Lincoln Street
)
[End] => Array
(
[id] => 1
[user_id] => 4
[country_id] => 1
[state_id] => 1
[city_id] => 4
[address] => Fifth Avenue
)
[Transport] => Array
(
[id] => 1
[name] => car
)
)
Here is the question:
How do I get in one query all the information down the tree?
I would like to have something like
Array
(
[Trip] => Array
(
[id] => 6
[created] => 2010-05-04 00:23:59
[User] => Array
(
[id] => 4
[name] => John Doe
[email] =>
[email protected]
)
[Start] => Array
(
[id] => 2
[user_id] => 4
[Country] => Array
(
[id] => 1
[name] = Spain
)
[State] => Array
(
[id] => 1
[name] = Barcelona
)
[City] => Array
(
[id] => 1
[name] = La Floresta
)
[address] => Lincoln Street
)
[End] => (same as Start)
[title] => My trip
[Transport] => Array
(
[id] => 1
[name] => car
)
)
)
Can
CakePHP create this kind of data?
Not only for $this->Model->find() but also for $this->paginate() as for example:
// filter by start
if(isset($this->passedArgs['start'])) {
//debug('isset '.$this->passedArgs['start']);
$start = $this->passedArgs['start'];
$this->paginate['conditions'][] = array(
'OR' => array(
'Start.address LIKE' => "%$start%",
'Start.State.name LIKE' => "%$start%",
'Start.City.name LIKE' => "%$start%",
'Start.Country.name LIKE' => "%$start%"
)
);
$this->data['Search']['start'] = $start;
}
It seems like a rough question but I am sure this is extensively done and documented, I'd really appreciate any help. Thanks
Cheers
