phalcon Dynamic Class creation fails with error? - php

Question

I am trying to create dynimic model class with a model function inside the user model, however for some reason it unable to identify the class location. it gives me an error
Fatal error: Class 'VarEducation' not found
below is the function
public function partner()
{
$view_service=new ViewService();
$partner_vars_check=$view_service->getUserVarPartnerModelCheckMappingArray();
foreach($partner_vars_check as $partner_key=>$partner_var){
$table= str_replace("p_","var_",$partner_key);
$sql = "SELECT * FROM ".$table."
WHERE id='" . $this->{$partner_key} . "'
ORDER BY id DESC";
$partner_obj = new $partner_var();
$this->{$partner_key} = new \Phalcon\Mvc\Model\Resultset\Simple(null, $partner_obj,
$partner_obj->getReadConnection()->query($sql));
}
}
Any idea on what causing this ?
data supplied by the view service is as below
public function getUserVarPartnerModelCheckMappingArray() {
return array(
'p_education' => 'VarEducation',
'p_body' => 'VarBody',
'p_ethnicity' => 'VarEthnicity',
'p_religion' => 'VarReligion',
'p_family' => 'VarFamily',
);
}

Answer 1

Whatever you do, if you have model hidden in any namespace, you have to deliver full namespaces with your mapping array. Lets say, all your models are in namespace of Application\Models, you have to use it this way:
public function getUserVarPartnerModelCheckMappingArray() {
return array(
'p_education' => '\Application\Models\VarEducation',
'p_body' => '\Application\Models\VarBody',
'p_ethnicity' => '\Application\Models\VarEthnicity',
'p_religion' => '\Application\Models\VarReligion',
'p_family' => '\Application\Models\VarFamily',
);
}
Not saying that I would rather switch/case over such a small amount of options and use models directly, instead of building SQL by hand.

Phalcon should load classes correctly even if the class name is a variable. Try isolating the problem down to just:
$myClass='VarEducation';
$partner_obj = new $myClass();
Also try commenting out that particular model from your model list and see if your other models work, perhaps there's an error in finding that particular model but not others. Check your /app/config/loader.php file and make sure you're registering your models directory. Then make sure the file VarEducation.php exists in your models directory as well as your other models. Also make sure that the class name inside the file matches the file name, and you've named the class VarEducation. Also make sure it's not namespaced. Also make sure you didn't forget the leading <?php and that the file doesn't have any errors. If all else fails, you can simply load the class from your loader.php file with something like:
$loader->registerClasses(array(
'VarEducation' => $config->application->modelsDir.'/VarEducation.php'
));
Make sure a simple test for the model works: $x=new VarEducation(); I suggest doing this from your index controller under a test action. If none of this works, comment on this post with your results when trying my suggestions and I'll update my answer.
