使循环依赖的模型属性在graphene-django中可查询

from django.db import models

class ModelA(models.Model):
    name = models.CharField(max_length=100)
    model_b = models.ForeignKey('ModelB', on_delete=models.CASCADE)

class ModelB(models.Model):
    name = models.CharField(max_length=100)
    model_a = models.ForeignKey('ModelA', on_delete=models.CASCADE)

import graphene
from graphene_django import DjangoObjectType

class ModelAType(DjangoObjectType):
    class Meta:
        model = ModelA

class ModelBType(DjangoObjectType):
    class Meta:
        model = ModelB

class ModelAType(DjangoObjectType):
    model_b = graphene.Field(lambda: ModelBType)

    def resolve_model_b(self, info):
        # 使用lambda函数延迟解析模型B的属性
        return self.model_b

class ModelBType(DjangoObjectType):
    model_a = graphene.Field(lambda: ModelAType)

    def resolve_model_a(self, info):
        # 使用lambda函数延迟解析模型A的属性
        return self.model_a
