【python】mongo删除数据

参考：https://stackoverflow.com/questions/23334743/setting-justone-limiter-for-pymongo-remove-throws-typeerror

 

正确的写法：

collection.remove({"_id":earliest_id_date["_id"]})

或

ufo.users.remove({'emails.address': 'foo@bar.com'}, safe=True)

 

 

下面这个写法会报错：

collection.remove({"_id":earliest_id_date["_id"]}, 1)

后面不能写1，会报错raise TypeError("Wrong type for %s, value must be a boolean" % (option,))
