无法使用 Eve 获取 dict 中的嵌入式文档

Question

我正在现有 MongoDB 结构之上构建只读 API，似乎无法在我的主调用中显示嵌入式文档。

有问题的示例文档（已编辑）..

{
  "_id": ObjectId("54a31721372a3b0f00000017"),
  "contentType": "document",
  "created": ISODate("2014-12-30T21:20:33.408Z"),
  "dcsId": "e14.0483",
. . .
  ,
   "metadata": {
     "amountTotal": 315.05,
     "amountNeto": 252.04,
     "partner": ObjectId("53bd4d851899424c0700005e")
  },
. . .

合作伙伴是我试图嵌入文档调用中的...

我的文档架构（用作 ura）...

docsSchema = {
    'dcsId': {
        'type': 'string',
        'required': True,
        'unique': True
    },
    'modified': {
        'type': 'datetime'
    },
    'created': {
        'type': 'datetime'
    },
    'downloadUrl': {
        'type': 'string'
    },
    'metadata': {
        'partner': {
            'type': 'objectid',
            'data_relation': {
                'resource': 'partners',
                'field': '_id',
                'embeddable': True

            }
        },
        'documentType': {'type': 'string'},
        'amountTotal': {'type': 'float'},
        'amountNeto': {"type": "float"}

    }
}

我的伙伴架构

partnersSchema = {
    "name": {"type": "string"}
}

以及两者的资源定义.....

from schemas import coreSchemas

ura = {
    'datasource': {
        'source': 'documents',
        'filter': {'metadata.documentType': 'URA'},
        'default_sort': [('_id', 2)],
        'projection': {
            "metadata.amountNeto": 1,
            "metadata.amountTotal": 1,
            "metadata.partner": 1,
            "created": 1,
            "modified": 1,
            "dcsId": 1},
        'embedding': True
    },
    'cache_control': 'max-age=10,must-revalidate',
    'cache_expires': 10,
    'resource_methods': ['GET'],
    'scheme': coreSchemas.docsSchema,
    'url': 'ura',
    "embedded_fields": {"metadata.partner"}
}

partners = {
    'datasource': {
        'source': 'partners',
        'filter': {'deleted': {'$ne': True}},
        # 'projection': {'metadata': 1, 'modified':1,'created':1, 'drive.webContentLink' : 1 , 'deleted': {'$ne':True}}
    },
    'cache_control': 'max-age=10,must-revalidate',
    'cache_expires': 10,
    'resource_methods': ['GET'],
    'scheme': coreSchemas.partnersSchema,
    'url': 'partners',
    "embedding": True
}

我调用 "ura" 端点只给我合作伙伴的 ID（不是嵌入）...

我在这里错过了什么？

Answer 1

当前不支持嵌入子字段（字典）。来自限制段落 Document Embedding:

Currently we support embedding of documents by references located in any subdocuments (nested dicts and lists). For example, a query /invoices?/embedded={"user.friends":1} will return a document with user and all his friends embedded, but only if user is a subdocument and friends is a list of reference (it could be a list of dicts, nested dict, ect.). We do not support multiple layers embeddings.

无法使用 Eve 获取 dict 中的嵌入式文档
