mongodb - 可以使用 mongodb 查询更新文档,但在 mongoose 中执行时不起作用
问题描述
我的收藏是这样的:https ://mongoplayground.net/p/91InBXrUq7R
有了这个查询,我可以更新replies.likes
db.getCollection("posts").updateOne(
{
"_id": ObjectId("5da832caeb173112348e509b"), //posts._id
"comments.replies._id":ObjectId("5db6a88f7c6cfb0d0c2b689b"),//replies._id
},
{ "$push": { "comments.$[outer].replies.$[inner].likes": "10000012" } },
{
"arrayFilters": [
{ "outer._id": ObjectId("5db06e11d0987d0aa2cd5593") },//comments._id
{ "inner._id": ObjectId("5db6a88f7c6cfb0d0c2b689b") }//replies._id
]
}
)
但是当我使用猫鼬编码时,快递,集合不更新
//Like Reply toggle
router.post("/toggleLikeReply", function(req, res, next) {
var id_post = req.body.id_post;
var id_comment = req.body.id_comment;
var id_reply = req.body.id_reply;
var id_user = req.user._id;
console.log("id_post: "+id_post+" id_comment: "+id_comment+" id_reply: "+id_reply+" id_user: "+id_user);
//todo
Post.aggregate([
{ $match: {_id: ObjectId(id_post),"comments._id": ObjectId(id_comment)}},
{ $unwind: "$comments"},
{ $match: { "comments._id": ObjectId(id_comment)}},
{ $project: {"replies": "$comments.replies", _id: 0}},
{ $match: { "replies._id": ObjectId(id_reply)}},
{ $project: {"likes": "$replies.likes", _id: 0}},
]).exec((err, users_liked) => {
var index = users_liked[0].likes[0].indexOf(id_user);
console.log(users_liked[0].likes[0]);
//todo
if (index == -1) {
const updatePost = async () => {
try {
await Post.updateOne({
_id: ObjectId(req.body.id_post),
"comments.replies._id": ObjectId(req.body.id_reply)},
{ $push: {"comments.$[outer].replies.$[inner].likes": ObjectId(req.user._id)} },
{
"arrayFilters": [
{ "outer._id": ObjectId(req.body.id_comment) },
{ "inner._id": ObjectId(req.body.id_reply) }
]
}
);
} catch (error) {
console.log("error", error);
}
};
updatePost().then(function(data) {res.send({ like: true, success: true})});
}else{
const updatePost = async () => {
try {
await Post.updateOne({
_id: ObjectId(req.body.id_post),
"comments.replies._id": ObjectId(req.body.id_reply)},
{ $pull: {"comments.$[outer].replies.$[inner].likes": ObjectId(req.user._id)} },
{
"arrayFilters": [
{ "outer._id": ObjectId(req.body.id_comment) },
{ "inner._id": ObjectId(req.body.id_reply) }
]
}
);
} catch (error) {
console.log("", error);
}
};
updatePost().then(function(data) {res.send({ like: false, success: true})});
}
})
});
我记录了所有的 id,就像我直接使用 mongo 查询一样。
id_post: 5da832caeb173112348e509b
id_comment: 5db06e11d0987d0aa2cd5593
id_reply: 5db6a88f7c6cfb0d0c2b689b
id_user: 5da85558886aee13e4e7f044
我的代码使用猫鼬和快递有什么问题?
解决方案
试试这个查询
var mongoose = require('mongoose');
const Schema = mongoose.Schema
const ObjectId = Schema.Types.ObjectId
const updatePost = async () => {
try {
await Post.updateOne({
_id: ObjectId(req.body.id_post),
"comments.replies._id": ObjectId(req.body.id_reply)},
{ $push: {"comments.$[outer].replies.$[inner].likes": req.user._id} },
{
"arrayFilters": [
{ "outer._id": ObjectId(req.body.id_comment) },
{ "inner._id": ObjectId(req.body.id_reply) }
]
}
);
} catch (error) {
console.log("error", error);
}
};
updatePost().then(function(data) {res.send({ like: true, success: true})});
