使用MongoEngine进行复杂的MongoDB查询

Question

人！

我正在尝试使用MongoDB（版本3.2）和MongoEngine并希望进行复杂的查询，但我完全不知道如何制作它。如果它甚至可能。

有4个文件：

class File(EmbeddedDocument):
    path = StringField()

class Episode(EmbeddedDocument):
    num = IntField()
    alias = StringField()
    files = EmbeddedDocumentListField('File')

class Season(Document):
    num = IntField()
    alias = StringField()
    episodes = EmbeddedDocumentListField('Episode', db_field='items')

class Series(Document):
    title = StringField()
    alias = StringField()
    description = StringField()
    seasons = ListField(ReferenceField('Season'), db_field='items')

我需要进行返回以下表单响应的查询：

[{
   "path": "/series/<series alias>",
   "title": "<series title>",
   "description": "<series description>",
   "seasons": [{
                "path": "/series/<aseries alias>/<season alias>",
                "title": "Season <season num>",
                "episodes": [{
                    "path": "/series/<series alias>/<season alias>/<episode alias>",
                    "title": "Episode <episode num>",
                    "files": [{
                        "path": "<path>"
                    }]
                }]
             }]
}]

是否可以仅使用一个查询接收响应？
