如何在graphene解析器中调用django模型函数？

Question

我的模型有 getQuality 中定义的函数。

Graphql类型是

class Person(DjangoObjectType):
   class Meta:
      model = PersonModel

   quality = graphene.String()

   def resolve_quality(self, info):
      person = PersonModel.objects.get(pk = self.id)
      return person.getQuality()

这可能会奏效，但我将对同一个对象进行两次查询。如何在解析器中调用模型函数？

Answer 1

class Person(DjangoObjectType):
   class Meta:
      model = PersonModel

   quality = graphene.String()

   def resolve_quality(self, info):
      return self.getQuality()
