PatchDict util

[vitalik]

PatchDict container allows to convert any schema into all-optional-fields schema and return a dict with only provided fields:

Usage example

from ninja import PatchDict

class GroupSchema(Schema):
    # You do not have to make fields optional it will be converted by PatchDict
    name: str
    description: str
    due_date: date


@api.patch("/patch/{pk}")
def modify_data(request, pk: int, payload: PatchDict[GroupSchema]):
    obj = MyModel.objects.get(pk=pk)

    for attr, value in payload.items():
        setattr(obj, attr, value)
    
    obj.save()
