我正在尝试为"复杂"对象实现GrapgQL变异.比方说,我们有一个Contact带有三个字段:firstName,lastName并且address,这是一个字段对象street:
这是我的python方案实现:
class Address(graphene.ObjectType):
street = graphene.String(description='Street Name')
class AddressInput(graphene.InputObjectType):
street = graphene.String(description='Street Name', required=True)
class Contact(graphene.ObjectType):
first_name = graphene.String(description='First Name')
last_name = graphene.String(description='Last Name')
address = graphene.Field(Address, description='Contact address')
class ContactInput(graphene.InputObjectType):
first_name = graphene.String(description='First Name', required=True)
last_name = graphene.String(description='Last Name', required=True)
address = AddressInput(description='Contact address', required=True)
class CreateContact(graphene.Mutation):
class Input:
contact = ContactInput()
contact = graphene.Field(Contact, description='Created Contact object')
@staticmethod
def mutate(instance, args, context, info):
contact = Contact(**args['contact'])
return …
