Is it possible to use inheritance on value objects embedded in doctrine entities?
The situation I'm thinking about is:
I have an entity that has and embedded value object. That value object has the following hierarchy:
class myEntity {
/** @Embedded(class = "baseValueObject") */
private $value_object;
...
}
class baseValueObject {...}
class valueObject1 extends baseValueObject{...}
class valueObject2 extends baseValueObject2{...}
If I define my entity to have baseValueObject as an embeddable, nothing happens when I use the schema-tool to update my db schema, so I guess that's not the way to do it.
Another option that I'm thinking about is to use single-table inheritance on the entity to create a child entity that use one of the value objects, and another child entity for the other one. Like this:
class myEntity {
/** @Embedded(class = "baseValueObject") */
private $value_object;
...
}
class myEntityA extends myEntity {
/** @Embedded(class = "valueObject1") */
private $value_object;
...
}
class myEntityB extends myEntity {
/** @Embedded(class = "valueObject2") */
private $value_object;
...
}
class baseValueObject {...}
class valueObject1 extends baseValueObject{...}
class valueObject2 extends baseValueObject2{...}
What's the proper approach? Is it even possible to do it this way?
