dump/load gives Invalid input type

[neggert]

Using schema().load() does not seem to work for classes that contain lists. I can reproduce this even with the Boss/Minion example from the documentation

@dataclass_json
@dataclass(frozen=True)
class Minion:
    name: str


@dataclass_json
@dataclass(frozen=True)
class Boss:
    minions: List[Minion]

boss = Boss([Minion('evil minion'), Minion('very evil minion')])
boss_dict = Boss.schema().dump(boss)
Boss.schema().load(boss_dict)

marshmallow.exceptions.ValidationError: {'_schema': ['Invalid input type.']}

For what it's worth, going all the way to JSON and back seems to work fine:

boss_json = boss.to_json()
Boss.from_json(boss_json)

Same issue with 0.2.1

[nuklea]

from dataclasses import dataclass
from typing import List

from dataclasses_json import DataClassJsonMixin


@dataclass
class Entity(DataClassJsonMixin):
    id: int


@dataclass
class Container(DataClassJsonMixin):
    entities: List[Entity]


@dataclass
class Data(DataClassJsonMixin):
    container: Container


schema = Data.schema()
schema.load({'container': {'entities': [{'id': 1}]}})

marshmallow.exceptions.ValidationError: {'container': {'entities': {'_schema': ['Invalid input type.']}}}

But works fine with 0.1.0

Thanks for reporting this. Fixed in #66
