php - Symfony 2 trouble with Single Table Inheritance -

-

i'm new symfony , doctrine , i'm trying implement simple user registration system 2 types of users, client , expert.

i have abstract class usuario common data both users share , other 2 extend it.

the problem when run command app/console doctrine:schema:update, generates table usuario fields of usuario class 1 experto class.

here code:

class usuario:

/**  * usuario  *  * @orm\entity  * @orm\table(name="usuario")  * @orm\inheritancetype("single_table")  * @orm\discriminatorcolumn(name="tipo", type="string")  * @orm\discriminatormap( {"cliente" = "cliente", "experto" = "experto"} )  */  abstract class usuario { /**  * @var integer  *  * @orm\id  * @orm\column(name="id", type="integer")  * @orm\generatedvalue(strategy="auto")  */ protected $id;  /**  * @var string $nombre  *  * @orm\column(name="nombre", type="string", length=255)  */ protected $nombre;  /**  * @var string $email  *  * @orm\column(name="email", type="string", length=255)  */ protected $email;  /**  * @var string $password  *  * @orm\column(name="password", type="string", length=32)  */ protected $password;  /**  * @var \datetime $fecha_registro  *  * @orm\column(name="fecha_registro", type="datetime")  */  setters , getters

class experto:

/**  * experto  *  * @orm\entity(repositoryclass="quienlorepara\usuariosbundle\entity\expertorepository")  */ class experto extends usuario { /**   * @var string $nombre_negocio  *  * @orm\column(name="nombre_negocio", type="string", length=255)  */ protected $nombre_negocio;  /*  * @var text $descrip_negocio  *  * @orm\column(name="descrip_negocio", type="text")  */ protected $descrip_negocio;  /*  * @var string $descripcion  *  * @orm\column(name="direccion", type="string", length=255)  */ protected $direccion;  /*  * @var string $telefono  *  * @orm\column(name="telefono", type="string", length=255)  */ protected $telefono;  /*  * @var string $actividad  *  * @orm\column(name="actividad", type="string", length=255)  */ protected $actividad;  /*  * @var decimal $latitud  *  * @orm\column(name="latitud", type="decimal", precision=10, scale=8)  */ protected $latitud;  /*  * var decimal $longitud  *  * @orm\column(name="longitud", type="decimal", precision=11, scale=8)  */ protected $longitud;  /**   * @var collection  * @orm\onetomany(targetentity="skill", mappedby="experto")  * @orm\joincolumn(name="usuario_id", referencedcolumnname="id")  */ protected $skills;

the result table called usuario properties of class usuario , property nombre_negocio of experto class. ideas i'm doing wrong? in advance.

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.
