hello every body
I’m having trouble with lazy loading .
Every thing is working fine on my developpement environement (wamp on widows).
But when i’m putting the projrct in the production environement (wampp on ubuntu) , lazy loading didn’t work .
notice that i’m using auto lazy loading.
please help !
Check file/class names. MyClass.php != myclass.php.
hello every body ,
thanks for reply.
I’ve found in other topic’s that my problem is might be caused by the case sensitive issues.
I’m sure that it’s not my problem because all my classes are generated by Gii.
i’ve now spent two weeks inthis issue , my conclusing is that :
lazy loading is not working at all in wamp seerver 2.2 and it’s working on wamp server 2.1 .
I’ have to make it work with the 2.2 and for now i didn’t find a solution.
Please help me !
this is version of the two servers , both have same php.ini and httpd.conf configuration
Wamp server 2.1 :
Apache 2.2.17
Php 5.3.5
Mysql 5.5.8
XDebug 2.1.0-5.3
XDC 1.5
PhpMyadmin 3.3.9
SQLBuddy 1.3.2
webGrind 1.0
Wamp server 2.2 :
Apache 2.2.21
Php 5.3.10
Mysql 5.5.20
XDebug 2.1.2
XDC 1.5
PhpMyadmin 3.4.10.1
SQLBuddy 1.3.3
webGrind 1.0
My conclusing is wrong !
lazy loading doesn’t work in both serser in other machine (windows, linux) .
I dont know what is installed in my environement that make it work 
wath are requirements to lazy loading ? some php extention ? some confiuration ?
Can you post the code you are running ? My experience is that Yii is pretty solid and when things go wrong it is normally down something I did when I was sleep coding 
this is an exemple of my code , that might help for diagnostic my problem.

in action :

}
$this->render('index', array(

and the code that work in windows and not work in ubuntu is :
foreach ($totos as $toto) {
foreach ($toto->totoEatStufs as $eatStuf) {
if (in_array($eatStuf->stuf->name, $stufs)) {
$stufs[] = $eatStuf->stuf->name;
$sommeAliments[$eatStuf->stuf->name] = $eatStuf->quantite;
} else {
$sommeAliments[$eatStuf->stuf->name]+=$eatStuf->quantite;
}
}
}
it’s tell me invalid forech in the second foreach loop
Hi,
I wonder why you are doing this in your action :
foreach ($totos as $toto) {
$toto->totoEatStufs = TotoConsommeAliment::model()->findAllByAttributes(array('toto_id' => $toto->id));
}
The aim of lazy loading is to load related record… on demand. (and I guess TotoConsommeAliment is a typo and you meant TotoEatStuff 
)
And, for tests, did you try with the eager loading approach
$totos=toto::model()->with('totoEatsStufs')->findAll()
it’s a workround solution fon make it work , you right it’s TotoEatsStufs 
the eager loading also just work in my developement server and don’t work on others servers .
I figure out what is the diference between servers :
it’s in php.ini file :
error_reporting= E_ALL ,
in my dev environement it’s set to
error_reporting =E_STRICT
True what you said about E_STRICT and E_ALL.
And what is the solutions on this?
I have this problem:
[b]`models\User.php`[/b]
public function relations() {
return array(
'city'=> array(self::BELONGS_TO,'City','cityid'),
'subscribers'=>array(self::HAS_MANY,'Userssubscribers','follower_id'),
'_address'=> array(self::BELONGS_TO,'Address','address'),
);
}
[b]`UserController.php`[/b]
$user = User::model()->with('city')->with('_address')->findByPk($user_id);
$result = new stdClass;
$result->id = $user->id;
$result->first_name = $user->first_name;
$result->last_name = $user->last_name;
$result->address = new stdClass();
$result->address->id = isset($user->_address->id) ? $user->_address->id : '';
$result->address->name = isset($user->_address->name) ? $user->_address->name : '';
$result->privileges = new stdClass;
$result->privileges->view_mail = isset($user->view_mail) ? $user->view_mail : '';
$result->privileges->view_first_name = isset($user->view_first_name) ? $user->view_first_name : '';
<h1>PHP Error [8]</h1>
<p>Undefined property: stdClass::$_address (C:\www\town_rally\src\protected\models\User.php:457)</p>
This line: $result->address->id = isset($user->_address->id) ? $user->_address->id : ‘’;
Actually $user->_address isset, and id has value with var_dump.
Edit later (fixed): Update
In my case, the problem was with lazy loading. My code, actually is a function getFormattedUser($user, $param) and $user is already an User Object. I needed to get the object again to have it’s values in the function context.
