如何使用pymongo在查询中插入新字段？

Question

我希望能够向要从主数据库查询的数据添加新字段。

如果我在下面运行以下代码：

database_connection = MongoClient(database_address)
collection = database_connection.db.collection

id_list = [1,2,3,4]

leads_list = []

for i in id_list[0:2]:
    leads = list(collection.find({ 'prospects': int(i) }, {
        '_id':0,
        'created': 1,
        'prospects': 1,
        'tags': 1
        }
    ))
    leads_list.extend(leads)

我得到这个结果：

[{'tags': [],
  'prospects': [1],
  'created': datetime.datetime(2016, 9, 5, 14, 59, 2, 782000)},
 {'tags': [],
  'prospects': [1],
  'created': datetime.datetime(2016, 12, 15, 7, 19, 48, 449000)},
 {'tags': [],
  'prospects': [2],
  'created': datetime.datetime(2016, 12, 30, 6, 19, 36, 474000)},
 {'tags': [],
  'prospects': [2],
  'created': datetime.datetime(2017, 5, 15, 17, 7, 59, 171000)},
 {'tags': [],
  'prospects': [3],
  'created': datetime.datetime(2017, 6, 28, 1, 32, 6, 953000)},
 {'tags': [],
  'prospects': [4],
  'created': datetime.datetime(2017, 10, 7, 7, 3, 42, 54000)}]

我想在其中添加一个新字段，并得到如下内容：

[{'id': 1
  'tags': [],
  'prospects': [1],
  'created': datetime.datetime(2016, 9, 5, 14, 59, 2, 782000)},
 {'id': 1
  'tags': [],
  'prospects': [1, 23],
  'created': datetime.datetime(2016, 12, 15, 7, 19, 48, 449000)},
 {'id': 2
  'tags': [],
  'prospects': [2],
  'created': datetime.datetime(2016, 12, 30, 6, 19, 36, 474000)},
 {'id': 2
  'tags': [],
  'prospects': [2, 34, 56],
  'created': datetime.datetime(2017, 5, 15, 17, 7, 59, 171000)},
 {'id': 3
  'tags': [],
  'prospects': [3, 35, 64],
  'created': datetime.datetime(2017, 6, 28, 1, 32, 6, 953000)},
 {'id': 4
  'tags': [],
  'prospects': [4, 12, 46],
  'created': datetime.datetime(2017, 10, 7, 7, 3, 42, 54000)}]
