Mongoose - findOneAndUpdateを使ってサブ文書を更新する

Question

特定の方法がうまくいかないかどうかわかりません。 findOneAndUpdateはサブ文書を操作する必要がありますか？

react/redux/expressを使用してください。

経路：

app.route("/api/positions/:position_id").put(function(req, res) { 
const _id = req.params.position_id; 
const update = req.body; 
process.nextTick(function() { 
    // for each element in req.body -> I will update the correct field 
    Project.findOneAndUpdate({_id : _id}, update, { new: true }, function(
    err, 
    updatedDoc 
) { 
    if (err) 
     res.send(err); 
    else if (!updatedDoc) 
     res.json({ message: "No Position Found", _id }); 
    else { 
     console.log(updatedDoc); 
     res.json({ 
     message: "Update Successful", 
     updatedDoc 
     }); } 
    }); 
}); 

}）。

{ 
    "message": "No Position Found", 
    "_id": "58d1908861f3513dc0c85f7d" 
} 

をしかし、サブドキュメントは間違いなくDBに存在します：

EDIT：

// schema for open positions in a project 
var positionSchema = mongoose.Schema({ 
    position_title: String, 
    position_description: String, 
    position_tags: Array, 
    archived: Boolean, 
    archivedDate: Date

// schema for single project data 
var projectSchema = mongoose.Schema({

    type: Boolean, 
    default: true

    type: String, 
    default: "Idea"

// expose schema to app 
module.exports = mongoose.model("Project", projectSchema); 

Answer 1

をあなたはopen_positions埋め込まれた配列内の_idフィールドをクエリ：

ことができます場合、これはスキーマです。したがって、クエリ部分ではopen_positionsとそれに続くIDを参照する必要があります。

クエリ部に配列リファレンスを使用するときに、一致する配列要素のインデックスへの参照を有しており、更新部にMongoのは、配列要素を置換することによって、続いて、以前に見つかった配列インデックスを持つ$を置き換えるプレースホルダ$位置演算子を得ますあなたのupdate書類で

使用

Project.findOneAndUpdate({"open_positions._id" : _id}, { "open_positions.$" : update }, { new: true }....
