Question

My problem is I can not find if it is somehow possible to specify a field to be transient.

I know that in java (JPA) you can specify it this way:

@Transient int transient;

There is a similar method in Doctrine2?

Answer 1

Each field on an entity that doctrine persists must be explicitly mapped (e.g., with annotations or YAML). If you don’t want a field on an entity to be persisted then don’t add any doctrine mapping for it:

/** @Entity */
class MyPersistentClass
{
    /** @Column(type="integer") */
    private $id; // will be persisted because it has a mapping

    private $name; // won't be persisted because it does not have a mapping
}
