如果我使用变量作为值，则在python中进行Mongo查询 [英] Mongo query in python if I use variable as value

问题描述

我正尝试使用以下查询从mongo集合中查找文档. db.collection_name.find({"id" : Id})其中id是变量正在作为输入.但这是行不通的.如果我用硬编码这样的值db.collection_name.find({"id" : "1a2b"})，它将起作用. "id"是字符串类型，正在使用pymongo访问mongo DB.

Am trying to find documents from the mongo collection using the following query. db.collection_name.find({"id" : Id}) where Id is the variable am getting as input. But it doesn't work. If I hard code the value like this db.collection_name.find({"id" : "1a2b"}) it works. "id" is of string type and am using pymongo to access mongo DB.

代码:

client = MongoClient("localhost:27017")                
db = client['sample_database']
Id = raw_input("enter id") 
cursor = db.collection_name.find({"id" : Id})

推荐答案

尝试str();

Id = str(raw_input("enter id"))
cursor = db.collection_name.find({"id" : Id})
