python - 如何将自定义模式传递给 drf detail_route？

Question

我有以下路线:

@detail_route(methods=['post'], permission_classes=[IsOperator], schema=AutoSchema(manual_fields=[
    coreapi.Field('size', location='query', schema={'type': 'number', 'example': 1024}),
    coreapi.Field('filename', location='query', schema={'type': 'string', 'example': 'telemetry.tlog'})
]))
def get_upload_url(self):
    # ...

当我转到显示我的模式的 View 时，我得到:

我收到以下错误:

AttributeError: 'AutoSchema' object has no attribute '_view'

在@list_route 和@details_route 中你可以这样添加

@list_route(
    schema=ManualSchema(fields=[
        coreapi.Field(
            "page",
            required=True,
            location="query",
            schema=coreschema.String()
        ),
        coreapi.Field(
            "page_size",
            required=True,
            location="query",
            schema=coreschema.String()
        ),
        coreapi.Field(
            "product_id",
            required=True,
            location="path",
            schema=coreschema.Integer()
        )
    ]),
    url_name='product',
    url_path='product/(?P<product_id>[0-9]+)'
)
