[英]MongoDB with mongoose: how to push an object to a nested array of documents?
[英]How to push data with Mongoose to a nested array in MongoDB
我正在嘗試將數據推送到 mongodb 中的嵌套數組。 我也在使用貓鼬。
這只是模擬代碼,看看我是否可以讓它工作:
用戶模型:
import mongoose from "mongoose";
const CoinSchema = new mongoose.Schema({
coinID: { type: String },
});
const CoinsSchema = new mongoose.Schema({
coin: [CoinSchema],
});
const WatchlistSchema = new mongoose.Schema({
watchlistName: { type: String },
coins: [CoinsSchema],
});
const NameSchema = new mongoose.Schema({
firstName: { type: String },
lastName: { type: String },
username: { type: String },
});
const UserSchema = new mongoose.Schema({
name: [NameSchema],
watchlists: [WatchlistSchema],
test: String,
});
const User = mongoose.model("User", UserSchema);
export default User;
路線:
fastify.put("/:id", async (request, reply) => {
try {
const { id } = request.params;
const newCoin = request.body;
const updatedUser = await User.findByIdAndUpdate(id, {
$push: { "watchlists[0].coins[0].coin": newCoin },
});
await updatedUser.save();
// console.dir(updatedUser, { depth: null });
reply.status(201).send(updatedUser);
} catch (error) {
reply.status(500).send("could not add to list");
}
});
request.body // "coinID": "test"
我嘗試了很多不同的方法來推送這些數據,但仍然沒有運氣。 我仍然在我的終端中收到 201 狀態代碼,這表明某些內容已被推送到數據庫,但是當我檢查沒有任何新內容時。
定位嵌套數組並將數據推送給它們的正確方法是什么?
這並不完美,但您可以獲取用戶文檔,更新用戶的監視列表,然后像這樣保存更新的監視列表:
fastify.put("/:id", async (request, reply) => {
try {
const { id } = request.params;
const newCoin = request.body;
// get the user
let user = await User.findById(id);
// push the new coin to the User's watchlist
user.watchlists[0].coins[0].coin.push(newCoin);
//update the user document
const updatedUser = await User.findOneAndUpdate({ _id: id },
{
watchlists: user.watchlists,
},
{
new: true,
useFindAndModify: false
}
);
reply.status(201).send(updatedUser);
} catch (error) {
reply.status(500).send("could not add to list");
}
});
