🚀 New issue to wemake-services/django-modern-rest by @sobolevn
📝 Change how we work with `FileMetadata` validation (#1493)


Currently, this code is allowed:

from typing import Literal

import pydantic

from dmr import Body, Controller, FileMetadata
from dmr.plugins.pydantic import PydanticSerializer
from dmr.parsers import JsonParser, MultiPartParser


class Text(pydantic.BaseModel):
    content_type: Literal['text/plain']


class Files(pydantic.BaseModel):
    text: Text


class MyController(Controller[PydanticSerializer]):
    parsers = [JsonParser(), MultiPartParser()]

    def post(
        self,
        parsed_body: Body[dict[str, str]],
        parsed_file_metadata: FileMetadata[Files],
    ) -> str:
        return 'done'

But, how can we ever satisfy?

• JsonParser()
• parsed_file_metadata: FileMetadata[Files]

It is not optional. Every request here will fail.
What we can do? Change

django-modern-rest/dmr/components.py

Lines 866 to 889 in f822e35

from any to all.
