php - Phalcon\Mvc\Model serialization - object properties are lost -

-

serializing phalcon\mvc\model loses object property that's not part of schema.

i have following model, upon load sets array of states:

class country extends phalcon\mvc\model {     protected $states;      public function initialize()     {         $this->setsource('countries');     }      public function afterfetch()     {         if ($this->id) {             $this->states = ['al', 'az', 'nv', 'ny'];         }     } }

i this:

    $country = country::findfirst($countryid);     $serialized = serialize($country);     $unserialized = unserialize($serialized);

$serialized string not contain "states" substring. hence, "states" missing in unserialized object.

i have discovered while working on user authentication , persistence in session (which involved serialization/unserialization). user object losing properties loaded in afterfetch() phase.

two questions:

  1. why did "states" property disappear upon serialization?
  2. is bad practice in phalcon world persist models (which thought convenient way of storing user object in session)?

i on phalcon 1.3.0.

thanks, temuri

\phalcon\mvc\model implements serializable interface.

to serialize own properties (which \phalcon\mvc\model unaware of), need use trick this: http://ua1.php.net/manual/en/class.serializable.php#107194

public function serialize() {     $data = array(         'states' => $this->states,         'parent' => parent::serialize(),     );      return serialize($data); }  public function unserialize($str) {     $data = unserialize($str);     parent::unserialize($data['parent']);     unset($data['parent']);     foreach ($data $key => $value) {         $this->$key = $value;     } }

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
