What if there are arbitrary items in POST Data?(question)

[mqnowa]

What if there are arbitrary items in POST Data?
In Python there is no “undefined” in javascript. So, if I want to manipulate the existence of a property, I have no choice but to pass a dict to POST.
But I want to use dataclass so that I can write programs with no documentation and only intellisense.
Is there a special variable or other solution that would prevent me from including that property in the data I post?

Translated with DeepL.com (free version)

@dataclass
class PostBody():
    required_property: str
    optional_property: str = UNDEFINED

class MyClient(RequestsClient):
    def __init__(): ...

    @post("/api/path")
    def post_api_path(self, body: PostBody) -> ResponceDataclass:
        pass

client = MyClient()
res = client.post_api_path(PostBody("foooo"))
# Posted Body: {"required_property": "foooo"}

One of the options is using TypedDict, it is like dict, but IDE will recognize supported keys.

But probably you are looking for skipping keys with default values during serialization.
Here is such an option: https://adaptix.readthedocs.io/en/latest/loading-and-dumping/extended-usage.html#omit-default

To apply that you need to override _init_request_body_factory in your Client class. It whould be something like:

class MyClient(RequestsClient):
    ...

    def _init_request_body_factory(self) -> Retort:
        return Retort(
            recipe=[
                name_mapping(PostBody, omit_default=True),
            ],
        )
