CatchAll with hash = False?

[hemna]

I've been using dataclasses-json to serialize my dataclasses. One issue I've been having with it is the inability to mark a CatchAll field as not hashable, so that when I call hash(mydcobject), the catchall isn't hashed. The reason for this is the the catchall is typically either a dict of dicts or list, which isn't hashable, and I end up with an exception like.

TypeError: unhashable type: 'dict

for example

@dataclass_json(undefined=Undefined.INCLUDE)
@dataclass(unsafe_hash=True)
class UnknownPacket:
    """Catchall Packet for things we don't know about.

    All of the unknown attributes are stored in the unknown_fields
    """

    unknown_fields: CatchAll

Normally, when I want a field to not be hashable to avoid this problem, I'd declare the field as hash=flase

@dataclass_json(undefined=Undefined.INCLUDE)
@dataclass(unsafe_hash=True)
class Foo:

    tPARM: Optional[list[str]] = field(default=None, hash=False)
   ...

the tPARM member won't be used in the hash(foo).

How, if at all, can I declare the CatchAll as hash=false ?

@hemna Hi — thanks for opening the discussion. I’m not entirely sure I’m following yet.

The examples and behavior you’re referencing seem to come from a different project. Could you clarify how this relates specifically to dataclass-wizard?

A minimal example using dataclass-wizard (or a description of what you’re trying to load/serialize with it) would help determine whether this is in scope here.

Thanks!
