石墨烯django为DjanoFilterConnectionField添加了额外的参数，并将其传递给get_query

Question

我向disposal_request查询添加了一个名为user_type的附加参数，我想使用此参数添加另一个筛选器，但当我将其传递给get_queryset函数时。我得到以下错误：get_queryset() missing 1 required positional argument: 'user_type'我不确定如何正确传递参数。

import graphene
import graphene_django
from app.disposer.models import DisposalRequest
from graphene_django.filter import DjangoFilterConnectionField
from graphql_jwt.decorators import login_required

class UserType(graphene.Enum):
as_collector = "as_collector"
as_disposer = "as_disposer"

class DisposalRequestsType(graphene_django.DjangoObjectType):
latitude = graphene.String()
longitude = graphene.String()
class Meta:
model = DisposalRequest
exclude = ("location",)
filter_fields = [
"uuid",
"disposal_status",
]
interfaces = (graphene.Node,)
convert_choices_to_enum = False
@classmethod
@login_required
def get_queryset(cls, queryset, info, user_type):
user = info.context.user
if user_type == UserType.as_collector:
print("as_collector")
return queryset.filter(collector=user)
elif user_type == UserType.as_disposer:
print("as_disposer")
return queryset.filter(disposer=user)
def resolve_latitude(self, _):
return self.location.x
def resolve_longitude(self, _):
return self.location.y
class DisposalQueries(graphene.ObjectType):
disposal_requests = DjangoFilterConnectionField(
DisposalRequestsType, user_type=UserType()
)

Answer 1

我最终为resolve_函数添加了额外的过滤器，并为DjangoFilterConnectionField添加的额外字段传递**kwargs

import graphene
import graphene_django
from app.disposer.models import DisposalRequest
from graphene_django.filter import DjangoFilterConnectionField
from graphql_jwt.decorators import login_required

class UserType(graphene.Enum):
as_collector = "as_collector"
as_disposer = "as_disposer"

class DisposalRequestsType(graphene_django.DjangoObjectType):
latitude = graphene.String()
longitude = graphene.String()
class Meta:
model = DisposalRequest
exclude = ("location",)
filter_fields = [
"uuid",
"disposal_status",
]
interfaces = (graphene.Node,)
convert_choices_to_enum = False
def resolve_latitude(self, _):
return self.location.x
def resolve_longitude(self, _):
return self.location.y

class DisposalQueries(graphene.ObjectType):
disposal_requests = DjangoFilterConnectionField(
DisposalRequestsType, user_type=UserType()
)
@staticmethod
@login_required
def resolve_disposal_requests(_, info, user_type, **__):
user = info.context.user
if user_type == UserType.as_collector:
return DisposalRequest.objects.filter(collector=user).all()
elif user_type == UserType.as_disposer:
return DisposalRequest.objects.filter(disposer=user).all()
