如何检查字符串是否在 pymongo.collection.collection 对象中
How to check if string is in pymongo.collection.collection object
我正在寻找解决此问题的方法,但找不到任何实用的方法
假设我们有一个 pymongo
collection
字符串,我们正在其中搜索名为 "tk_dd_id"
的字符串。
collection = Collection(Database(MongoClient(host=['123234'], document_class=dict, tz_aware=False, connect=True, ssl=True, replicaset='mongomongo'), 'health_cards'), 'tk_dd_id')
我试过了
if "tk_dd_id" in collection:
print("Found!")
'Collection' object is not iterable
类型(集合)
if any("tk_dd_id" in s for s in collection):
print("Found!")
'Collection' object is not iterable
type(collection)
<class 'pymongo.collection.Collection'>
这个问题似乎没有实际意义,因为您必须将集合名称作为参数传递给 Collection
对象。但是如果你必须查询名称,你可以使用 name
属性来完成:
from pymongo import MongoClient
from pymongo.collection import Collection
from pymongo.database import Database
collection_name = "tk_dd_id"
collection = Collection(Database(MongoClient(host=['123234'], document_class=dict, tz_aware=False, connect=True, ssl=True, replicaset='mongomongo'), 'health_cards'), collection_name)
if "tk_dd_id" in collection_name:
print("Found!")
if "tk_dd_id" in collection.name:
print("Found!")
