deserialize based on value?

Hi! I’m still playing with your amazing library. In continue of another question:

I’ve main dataclass:

@dataclass(slots=True)
class GameRequest(DataClassJSONMixin):
    c: int
    s: int
    d: Any
    o: str = None
    t: int = None

I’ve many other classes for different c value of main class and want to get them into d value. I tried to use field(metadata={"deserialize": ... }) and define custom _deserialize in SerializableType. But main problem is that i always get only dict, passed to d and i don’t have any references to main class request.

using {'c': 1, 's': 2, 'o': 3, 't': 12345, 'd': {'zzz': 'aaa'}} i always get only {'zzz': 'aaa'}

If the choice of the ReqX class depends on another field of GameRequest, you can use the post_deserialize hook:

@dataclass
class GameRequest(DataClassJSONMixin):
    c: int
    s: int
    d: Any
    o: str = None
    t: int = None

    @classmethod
    def __post_deserialize__(cls, obj):
        if obj.c == 1:
            obj.d = Req1.from_dict(obj.d)
        elif obj.c == 2:
            obj.d = Req2.from_dict(obj.d)
        elif obj.c == 3:
            obj.d = Req3.from_dict(obj.d)
        return obj

post_deserialize would be last thing on my mind Thanks! Worked.
