无法为石墨烯设置“schema”导入“art_project.schema.schema”。ImportError:无法导入名称“DjangoFilterConnectionField”

Question

我正在使用graphene.django，但是我在连接graphiql时遇到了一些问题

所有文件：

project schema.py：

import graphene
import art_app.customers.schema as customer

class Query(customer.Query, graphene.ObjectType):
    pass

class Mutation(customer.Mutation, graphene.ObjectType):
    pass

schema = graphene.Schema(query=Query, mutation=Mutation)

app querys.py：

import graphene
from graphene import relay, ObjectType
from graphene_django.filter import DjangoFilterConnectionField
from .types.nodes import CustomerUserNode

class CustomerUserQuery(ObjectType):
    customer_user = relay.Node.Field(CustomerUserNode)
    all_customer_users = DjangoFilterConnectionField(CustomerUserNode)

class Query(
    CustomerUserQuery, graphene.ObjectType,
):
    pass

app突变

create.py：

import graphene
from graphene import relay
from ...models import CustomerUserModel
from ..types.inputs import CustomerUserCreateInput
from ..types.nodes import CustomerUserNode

class CreateCustomerUser(relay.ClientIDMutation):

    class Input:
        new_customer_details = graphene.Field(CustomerUserCreateInput)

    created_customer_details = graphene.Field(CustomerUserNode)

    @classmethod
    def mutate_and_get_payload(cls, root, info, **input):
        created_customer_details = CustomerUserModel.objects.create(**input.get("new_customer_details"))
        file = info.context.FILES['image']
        created_customer_details.image = file
        return CreateCustomer(created_customer_details=created_customer_details)

delete.py：

import graphene
from graphene import relay
from ...models import CustomerUserModel
from ..types.inputs import CustomerUserCreateInput
from ..types.nodes import CustomerUserNode
from django.contrib.auth.decorators import login_required
from django.shortcuts import get_object_or_404
from graphql import GraphQLError


class DeleteCustomerUser(relay.ClientIDMutation):

    class Input:
        id = graphene.ID(required=True)

    deleted_customer_details = graphene.Field(CustomerUserNode)

    @classmethod
    def mutate_and_get_payload(cls, root, info, id):
        deleted_customer_details = get_object_or_404(CustomerUserModel, id=id)
        if deleted_customer_details.is_active:
            deleted_customer_details.is_active = False
            deleted_customer_details.save()
        else:
            raise GraphQLError("This user is not active!")

        return DeleteCustomerUser(deleted_customer_details=deleted_customer_details)

nodes.py：

from graphene import relay
from graphene_django import DjangoObjectType
from ...models import CustomerUserModel

class CustomerUserNode(DjangoObjectType):
    class Meta:
        model = CustomerUserModel
        filter_fields = []
        interfaces = (relay.Node, )

输入.py

    first_name = graphene.String(required=True)
    last_name = graphene.String(required=True)
    email = graphene.String(required=True)
    shipping_address = graphene.String()
    invoice_address = graphene.String()
