util.inspect/JSON.stringify在對象中的數組上不起作用

Question

我使用各種命令，find，findones，findone和updates等從mongodb中檢索文檔。其中大多數將返回保存的整個文檔，想。當找到或找到一個貓鼬允許使用人口。我試圖傳回傳遞給我的整個對象或查看整個對象，但數組出錯了。我仍然可以手動訪問這些值，但我想要整個對象的字符串等效。我試過JSON.stringify和util.inspect（）。任何人都可以解決這個問題？我見過一些解決這個問題的舊帖子。如果問題是我如何存儲信息，我將發佈我的模型以及有關更改的有用建議。

模型：第一產品，第二機器：

var productSchema = new Schema({ 
    productName: String, 
    produtDesc: String, 
    author: String, 
    lastUpdate: { type: Date, default: Date.now }, 
    minimum: { type: Schema.Types.ObjectId, ref: 'Machine' }, 
    recommended: { type: Schema.Types.ObjectId, ref: 'Machine' } 
}); 

var machineSchema = new Schema({ 
    cpu: { 
     speed: String, 
     mfg: [String], 
     family: [String], 
     cores: Number, 
     architecture: String 
    }, 
    memory: { 
     total: Number, 
     free: Number 
    }, 
    storage: [ { 
     drive: String, 
     total: Number, 
     free: Number 
    } ], 
    os: { 
     family: String, 
     version: String, 
     uptime: Number 
    }, 
    screen: { 
     height: Number, 
     width: Number 
    }, 
    browser: { 
     family: String, 
     version: String 
    }, 
    network: [ { 
     name: String, 
     speed: Number, 
     addresses: [ { 
      address: String, 
      type: String, 
      internal: Boolean 
     } ] 
    } ], 
    software: { 
     ".net": [String], 
     java: [String], 
     acrobat: String 
    } 
}); 

輸出代碼：

result.populate('recommended') 
    .populate('minimum') 
    .exec(function(err, done) { 
     console.log(util.inspect(done, 
      { showHidden: false, depth: 10 })); 
     console.log(done.recommended.network[0]); 
     reply(util.inspect(done, 
      { showHidden: false, depth: null })); 
    }); 

輸出樣本：第一util.inspect，第二JSON.stringify

// util.inspect

    recommended: 
    { _id: 553dc1d60062ee501b88535b,

     network: [ [Object] ],

    cpu: { cores: 4, speed: '2800', family: [Object], mfg: [Object] } }, 
    minimum:

Answer 1

事實證明，子文檔是這個問題的答案。在向數據庫插入部分期間，我正在使用JSON對象並將它們與我的機器模型的構造函數一起施放。新機器（數據）。直到我在我的模型中爲網絡子文檔和地址子文檔爲我的網絡地址屬性創建了架構之後，纔會執行此操作。

這裏是改變模式：

var addressSchema = new Schema({ 
    address: String, 
    type: String, 
    internal: Boolean 
}); 
var networkSchema = new Schema({ 
    name: String, 
    speed: Number, 
    addresses: [addressSchema] 
}); 
var machineSchema = new Schema({ 
    cpu: { 
     speed: String, 
     mfg: [String], 
     family: [String], 
     cores: Number, 
     architecture: String 
}, 
memory: { 
    total: Number, 
    free: Number 
}, 
storage: [{ 
    drive: String, 
    total: Number, 
    free: Number 
}], 
os: { 
    family: String, 
    version: String, 
    uptime: Number 
}, 
screen: { 
    height: Number, 
    width: Number 
}, 
browser: { 
    family: String, 
    version: String 
}, 
network: [networkSchema], 
software: { 
    ".net": [String], 
    java: [String], 
    acrobat: String 
} 
}); 

Answer 2

嘗試此

JSON.parse（JSON.stringify（addresses。[0]））;
