我用的是mongoengine 我的document 如下

# hosts表class Hosts(Document):    # 从业务库    IP = StringField(unique=True, null=False)    az_id = IntField(null=True)    meta = {        'collection': 'db_hosts'    }# 聚合信息表class AggregateDayHostMetric(Document):    # host是ObjectId类型存的是Hosts的_id(mongoengine里是.id来访问)    # 括号里的Hosts导致数据库里字段名变为Hosts而不是host    host = ObjectIdField('Hosts')    # 这里unique_with会自动创建一个联合索引，新加的话要删掉collection重新创建才会生效，这个会引发NotUniqueError    BusinessDay = IntField(null=False, unique_with='host')    # cpu_metric是指向另一个对象类型在eve可以理解为dict    cpu_metric = EmbeddedDocumentField('TypeValue', null=True)    meta = {        'collection': 'aggregate_day_host_metric'    }

AggregateDayHostMetric = {    'schema': {        'Hosts': {            'type': 'objectid',            'data_relation': {                'resource': 'db_hosts',                'field': '_id',                'embeddable': True            }        },        'BusinessDay': {            'type': 'integer'        },        'cpu_metric': {            'type': 'dict'        }    }}DOMAIN = {    'db_hosts': db_hosts,    'aggregate_day_host_metric': AggregateDayHostMetric}

配置完成，访问：
http://host:port/aggregate_day_host_metric?embedded={"Hosts": 1} 即可

# 返回的每个元素结构如下（eve帮你做了查询）{    "Hosts": {      "SecUsage": "pnat",      "IP": "114.114.114.114",      "_id": "578dde6f9746ef2cd80f9e70",      "Usage": "unet",      "az_id": 4001    },    "BusinessDay": 17031,    "cpu_metric": {      "top_5_avg": 54    },    # 下面是eve自带的暂时用不到，忽略    "_updated": "Thu, 01 Jan 1970 00:00:00 GMT",    "_created": "Thu, 01 Jan 1970 00:00:00 GMT",    "_id": "57b580739f37e9ac8a10e5ae",    "_etag": "8c20ca3037c79f2ad6bea2b1c31af1199651e29e"}
