graphene-mongo 0.2.8

安装

要安装graphene mongo，只需在shell中运行此命令

pip install graphene-mongo

示例

下面是一个简单的MongoEngine模型

frommongoengineimportDocumentfrommongoengine.fieldsimportStringFieldclassUser(Document):meta={'collection':'user'}first_name=StringField(required=True)last_name=StringField(required=True)

要为它创建graphql模式，您只需编写以下代码：

importgraphenefromgraphene_mongoimportMongoengineObjectTypefrom.modelsimportUserasUserModelclassUser(MongoengineObjectType):classMeta:model=UserModelclassQuery(graphene.ObjectType):users=graphene.List(User)defresolve_users(self,info):returnlist(UserModel.objects.all())schema=graphene.Schema(query=Query)

然后您可以简单地查询模式：

query='''
    query {
        users {
            firstName,
            lastName
        }
    }
'''result=schema.execute(query)
