hello,
I realize a web application with Symfony 2 from an existing database.
I have set up an entity with a primary key consisting of two foreign keys.
example:
Entity1 with a composite primary key: property1 (PK), property2 (PK)
Entity2 primary key consists of two foreign keys: property1 (PK FK),
property2 (PK FK), propriete3 (PK)
I don't how to implement this association:
In the entity2 i do :
/ **
> *ORM \ ManyToOne (targetEntity = "Entity1")
> *ORM \ JoinColumns ({
> *ORM \ JoinColumn (name = "property1" referencedColumnName = "property1")
> *ORM \ JoinColumn (name = "property2" referencedColumnName = "property2")
> * @ ORM \ Id
> *})
> * /
> private $entity1;
But I get an error:
*It is not possible to map entity 'ExempleBundle\Entity\Entite1' with a
composite primary key as part of the primary key of another entity
'ExempleBundle\Entity\Entite2#entite1'.*
How to properly handle this kind of association with Doctrine
I tried to follow this example but I do not understand :
http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/tutorials/composite-primary-keys.html#use-case-1-dynamic-attributes
<http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/tutorials/composite-primary-keys.html#use-case-1-dynamic-attributes>
Can you give an example of two entities with a similar case and especially
on how to make a joint in this case.
Thank you in advance.
Birzat
