如何接受字典/对象作为石墨烯（GraphQL）突变的输入？

Question

mutation{
createPayment(p_obj={"bob": 80, "job": 100}){
     <fields here>
     }
}

我可以找到的是接受对象列表作为输入，例如：

[ {username: "bob", "amount": 80}, {username: "job", "amount": 100} ]

您可以执行以下操作-

class PaymentInputType(graphene.InputObjectType):
      username = graphene.String()
      amount = graphene.Int()

并按如下所示在您的突变中使用InputType。

class CreatePayment(graphene.Mutation):
    class Arguments:
       input = PaymentInputType(required=True)

    ok = graphene.Boolean()

    @staticmethod
    def mutate(root, info, input):
        # save the changes here 
        return CreatePayment(ok=True)
