Ignoring field names equal to reserved keywords like "from"

[devgomax]

Hello! Here is the proto message for example:

message Range {
    google.protobuf.FloatValue from = 1;
    google.protobuf.FloatValue to = 2;
}

And there is the generated interface:

class Range(Message):
    DESCRIPTOR: Descriptor
    FROM_FIELD_NUMBER: int
    TO_FIELD_NUMBER: int
    @property
    def to(self) -> FloatValue: ...
    def __init__(self,
        *,
        to: Optional[FloatValue] = ...,
    ) -> None: ...
    def HasField(self, field_name: Literal["from",b"from","to",b"to"]) -> bool: ...
    def ClearField(self, field_name: Literal["from",b"from","to",b"to"]) -> None: ...

Unfortunately, generated model has no field named from.
So I have two questions:

1. How can I get/set this field while initialization of the model Range?
2. Is there any workaround for such fields?

Thanks in advance!

Hi. from is a python reserved keyword so it is skipped on the property. You will have to use some methods from the base class - the getattr and setattr
