Django Graphene，将JSON或dict数据作为突变输入 [英] Django Graphene, Passing JSON or dict data as input for Mutation

问题描述

我有以下情况：我有一个用户，每个用户都有一个清单。我正在努力在Mutation CreateUser中声明用户的广告资源。以下是创建用户的以下突变：

I have the following situation: I have a User, each user has a Inventory. I'm struggling to declare the user's inventory in the Mutation "CreateUser". Here is the following mutation for creating the user:

mutation Create{
  addUser(UserData:{name:"Shibunika",age:21}
}

我正在尝试在以下位置声明用户的广告资源这种突变，我期望像这样的

I'm trying to declare the user's inventory in this mutation, I expected something like

mutation Create{
  addUser(UserData:{name:"Shibunika",age:21,inventory:{'item1':45,'item2':25}
}s

这些数字是每件商品的数量。
我如何在石墨烯中定义这些输入？
您会为我轻轻地显示一个方案吗？

these number are the quantity of each item. How do I define these inputs in graphene? Would you gently show me a schema for this?

推荐答案

您可以创建一个自定义对象类型来表示一个键值对，然后在用户模式中列出这些对象。

You can create a custom object type to represent a key value pair, and then have a list of these in your user schema.

class InventoryKeyValueType(graphene.InputObjectType):
    name = graphene.String(required=True)
    int_value = graphene.Int(required=True)

class AddUser(graphene.Mutation):
    user = graphene.Field(lambda: UserType)
    ok = graphene.Boolean()

    class Arguments:
        # User Fields
        name = graphene.String()
        ....

        inventory = graphene.List(InventoryKeyValueType)

语法有点笨拙但可行：

mutation {addUser（name： Shibunika，年龄：21，广告资源：[{name： item1 ，intValue：45}，{name： item2，intValue：25}]）{ok}

其他输入类型

此方法可以轻松扩展到整数以外的其他输入类型，例如替换

This approach could easily be extended for other input types beyond integers, for example replacing

    int_value = graphene.Int(...

with

    str_value = graphene.String(...
