Schema

The graphene.Schema object describes your data model and provides a GraphQL server with an associated set of resolve methods that know how to fetch data. The most basic schema you can create looks like this:

import graphene

class Query(graphene.ObjectType):
    pass

class Mutation(graphene.ObjectType):
    pass

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

This schema doesn’t do anything yet, but it is ready to accept new Query or Mutation fields.

Adding to the schema

If you have defined a Query or Mutation, you can register them with the schema:

import graphene

import my_app.schema.Query
import my_app.schema.Mutation

class Query(
    my_app.schema.Query, # Add your Query objects here
    graphene.ObjectType
):
    pass

class Mutation(
    my_app.schema.Mutation, # Add your Mutation objects here
    graphene.ObjectType
):
    pass

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

You can add as many mixins to the base Query and Mutation objects as you like.
