如何在graphene-django中仅向用户配置文件所有者显示特定字段？

import graphene

class UserProfileType(graphene.ObjectType):
    id = graphene.ID()
    username = graphene.String()
    email = graphene.String()
    # 添加其他字段

    # 定义一个方法，用于判断当前用户是否为配置文件所有者
    def resolve_is_owner(self, info):
        user = info.context.user
        return self.user == user

class Query(graphene.ObjectType):
    user_profile = graphene.Field(UserProfileType)

    def resolve_user_profile(self, info):
        user = info.context.user
        if user.is_authenticated:
            return user.profile
        return None

schema = graphene.Schema(query=Query)

from graphene_django.views import GraphQLView

urlpatterns = [
    # 其他URL配置
    path('graphql/', GraphQLView.as_view(graphiql=True, schema=schema)),
]
