我尝试使用db.users.remove删除文档({_ id:“4f6f244f6f35438788aa138f”}) 但是这个命令不会删除任何内容。
> // myobject is some document that is in our db.things collection
> db.things.remove({_id: myobject._id});
我无法弄清楚'myobject是什么?'在mongodb文档中。
> db.users.find()
{ "_id" : ObjectId("4f6cd2cb7156522f4f45b26d"), "name" : "james", "age" : 23,
"hobbies" : [ "cycling", "painting" ] }
{ "_id" : ObjectId("4f6cd3017156522f4f45b26e"), "name" : "john", "age" : 30 }
{ "_id" : ObjectId("4f6f244f6f35438788aa138f"), "name" : "john" }
{ "_id" : ObjectId("4f6f24556f35438788aa1390"), "name" : "john" }
> db.users.remove({_id: "4f6f244f6f35438788aa138f"})
答案 0 :(得分:25)
你试过吗
db.things.remove({_id: ObjectId("4f6f244f6f35438788aa138f")});
您必须传递ObjectId,而不是字符串。
