无法使用symfony2将onetoone转换为学说中的onetomany

Question

I got hired about 2 weeks in a company, and my first task was to update and implement new features in an existing software written in symfony2-doctrine. But one of the changes I must make is just breaking my back.

The previous model was: one "cliente" (costumer) could have only one "credito" (credit) and one "credito" could have many "venta" (sales) The new model should be: one "cliente" (costumer) can have many "credito" and one "credito" can have many "venta" (Im keeping the onetomany association for backwards compatibity)

This is how my entities look like this:

cliente.php

class Cliente {
//put your code here
/**
 * @ORM\Id
 * @ORM\Column(type="integer")
 * @ORM\GeneratedValue(strategy="IDENTITY")
 */
protected $id;

 /**

/**

 * @ORM\JoinColumn(name="almacen_id",referencedColumnName="id")        
 */
protected $almacen;

/**
 * Get id
 *
 * @return integer 
 */

The problem is: everytime I insert a new "credito", it wont be linked to the existing "cliente" instead of that, it will try to insert a duplicate entry of "cliente". I've tried many things but none of them had any effect.

I appreciate any help, cause Im stuck with that. If further information or code is required I will gladly provide it.

Answer 1

The cascade={"persist"} should be the core of your problem:

class Credito {
......
/**
 * @ORM\ManyToOne(targetEntity="Cliente",cascade={"persist"})
 * @ORM\JoinColumn(name="cliente_id",referencedColumnName="id")     
 */
protected $cliente;

It tells doctrine to persist cleinte always when you persist Credito. See docs for more details http://doctrine-orm.readthedocs.org/en/latest/reference/working-with-associations.html#transitive-persistence-cascade-operations

Answer 2

Always tell Doctrine how to do in both sides of an association :

// credito.php
/**
 * @ORM\ManyToOne(targetEntity="Cliente", inversedBy="credito", cascade={"persist"})
 * @ORM\JoinColumn(name="cliente_id",referencedColumnName="id")     
 */
protected $cliente;

And

// venta.php
/**
 * @ORM\ManyToOne(targetEntity="Credito", inversedBy="ventas", cascade={"persist"})
 * @ORM\JoinColumn(name="credito_id",referencedColumnName="id")     
 */
protected $credito;
