貓鼬：'投射到嵌入路徑失敗的值。無法使用'in'運算符搜索'_id'

Question

我在嘗試在對象數組內保存數組時遇到了一些麻煩。

我從服務器獲取以下回應：

{ [CastError: Cast to embedded failed for value "\'maxbeds: 4\'" at path "saved_searches"] 
message: 'Cast to embedded failed for value "\\\'maxbeds: 4\\\'" at path "saved_searches"', 
name: 'CastError', 
kind: 'embedded', 
value: '\'maxbeds: 4\'', 
path: 'saved_searches', 
reason: [TypeError: Cannot use 'in' operator to search for '_id' in maxbeds: 4] } 

這裏是我的架構：

var mongoose = require('mongoose'), 
rfr = require('rfr'), 
passwordHelper = rfr('server/helpers/password.js'), 
Schema = mongoose.Schema, 
_ = require('lodash'); 

/* 
* 
* Creating UserSchema for MongoDB 
* 
*/ 

var UserSchema = new Schema({ 
email: { 
    type: String, 
    required: true, 
    unique: true 
}, 
password: { 
    type: String, 
    required: true, 
    select: false 
}, 
name: { 
    type: String, 
    required: true 
}, 
passwordSalt: { 
    type: String, 
    required: true, 
    select: false 
}, 
saved_houses: [{ 
    mlsId: { 
    type: String 
    }, 
    addressFull: { 
    type: String 
    }, 
    bedrooms: { 
    type: Number 
    }, 
    listPrice: { 
    type: Number 
    }, 
    bathrooms: { 
    type: Number 
    }, 
    sqft: { 
    type: Number 
    }, 
    createdAt: { 
    type: Date, 
    default: Date.now 
    } 
}], 
saved_searches: [{ 
    search_name: { 
    type: String 
    }, 
    filters: { 
    type: [Schema.Types.Mixed] 
    }, 
    createdAt: { 
    type: Date, 
    default: Date.now 
    } 
}], 
active: { 
    type: Boolean, 
    default: true 
}, 
createdAt: { 
    type: Date, 
    default: Date.now 
} 
}); 
// compile User model 
module.exports = mongoose.model('User', UserSchema); 

的問題，我認爲這是濾波器陣列住saved_searches內的物體內array

現在，在我的路由器中，我執行以下操作：

var express = require('express'), 
savedDataRouter = express.Router(), 
mongoose = require('mongoose'), 
rfr = require('rfr'), 
s = rfr('server/routes/config/jwt_config.js'), 
User = rfr('server/models/User.js'), 
jwt = require('jsonwebtoken'); 

savedDataRouter.post('/searches', function (req, res) { 
    if (mongoose.Types.ObjectId.isValid(req.body.userId)) { 
     User.findByIdAndUpdate({ 
       _id: req.body.userId 
      }, { 
       $push: { 
        saved_searches: { 
         search_name: req.body.search_name, 
         $each: req.body.filters 
        } 
       }, 
      }, { 
       new: true 
      }, 
      function (err, doc) { 
       if (err || !doc) { 
        console.log(err); 
        res.json({ 
         status: 400, 
         message: "Unable to save search." + err 

        }); 
       } else { 
        return res.json(doc); 
       } 
      }); 
    } else { 
     return res.status(404).json({ 
      message: "Unable to find user" 
     }); 
    } 
}); 

如果我登錄請求主體來自客戶端，我得到以下幾點：

//console.log(req.body) 
{ search_name: 'Sarasota', 
filters: [ 'minbaths: 1', 'maxbaths: 3', 'minbeds: 2', 'maxbeds: 4' ], 
userId: '583359409a1e0167d1a3a2b3' } 

我已經嘗試了所有我見過的StackOverflow和其他在線資源，沒有運氣的事。希望有人能指引我正確的方向或告訴我我做錯了什麼。

我真的很感激任何幫助，你可以給我同行的代碼。

添加模塊依賴於我的UserSchema和SavedDataRouter

試試這個

User.findByIdAndUpdate({ 
      _id: req.body.userId 
     }, { 
      $push: { 
       saved_searches: { 
        search_name: req.body.search_name, 
        filters: req.body.filters 
       } 
      }, 
     }, { 
      new: true 
     }, 
     function (err, doc) { 
      if (err || !doc) { 
       console.log(err); 
       res.json({ 
        status: 400, 
        message: "Unable to save search." + err 

       }); 
      } else { 
       return res.json(doc); 
      } 
     });
