Question

I'm completely new to GraphQL and graphene and i just finished the graphene_django tutorial

I understand how to get data from server, which is pretty easy, but i don't know how to do create or update

do i need to use django rest framwork for POSTs or is it possible to use just graphene to get and put data?

要在graphQL中创建或编辑对象，您必须使用称为变异的内容，以获取更多信息以及如何使用它阅读this from graphQL page。

现在在Django中你有一个名为schema.py的东西，你可以放置你的Class查询。在这里，我们还使用变异类来创建我们的突变，就像我们创建了查询一样。你的问题太宽泛，所以我给你一个教程，解释如何使用Django的突变。但应该是这样的：

class CreateMessageMutation(graphene.Mutation):
    class Input:
        message = graphene.String() #Parameters to create our model

    message = graphene.Field(MessageType) #This field is required to show our message

    @staticmethod
    def mutate(root, info, **kwargs):
        message = args.get('message', '').strip()

        obj = models.Message.objects.create(message=message)

        return CreateMessageMutation(status=200, message=obj)
        #Here we return the object to show what we have created 

class Mutation(graphene.AbstractType):
    create_message = CreateMessageMutation.Field()

和另一个schempa.py：

class Query(ingredients.schema.Query, graphene.ObjectType):
    # This class will inherit from multiple Queries
    # as we begin to add more apps to our project
    pass

class Mutation(ingredients.schema.Mutation, graphene.ObjectType):
    pass

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

How can i POST data with graphene_django?
