水線錯誤：「未知規則：默認」

Question

在模型上調用.create()時出現以下錯誤。

型號：

attributes: { 
    user : { 
     type: 'integer' 
    }, 
    number : { 
     type: 'string' 
    } 
    } 

電話：

sails.models.phone.create({ 
    user: 2, 
    number: '5555555555', 
    updated_at: Sun Nov 27 2016 16:59:45 GMT-0800 (PST) 
}); 

錯誤：

我該如何解決這個問題？

我查看了similar errors，但是我的型號都沒有default屬性，包括上面顯示的phone型號。爲什麼會發生這種情況，我該如何解決？

解決方案

所以事實證明，中.update()吃水線調用修改了輸入信息。我寫了一個函數來創建或更新水線模型，當他們修正auto updated_at issue時，他們必須修改傳入的信息。

我以前的代碼沒有工作：

createOrUpdate: function(model, primary, data){ 
    return model.update(primary, data) 
    .then(function updateCB(updated){ 
    if (updated.length == 0){ 
     return model.create(data) //data here had an added updated_at field 
     .then(function(created){ 
     return created; 
     }); 
    } 

    if (updated.length > 0){ 
     updated = updated[0]; 
    } 
    return updated; 
    }); 
} 

我的新代碼，做工作：

createOrUpdate: function(model, primary, data){ 
    const data1 = JSON.parse(JSON.stringify(data)); // deep copy 
    const data2 = JSON.parse(JSON.stringify(data)); // deep copy 
    return model.update(primary, data1) 
    .then(function updateCB(updated){ 
    if (updated.length == 0){ 
     return model.create(data2) 
     .then(function(created){ 
     return created; 
     }); 
    } 

    if (updated.length > 0){ 
     updated = updated[0]; 
    } 
    return updated; 
    }); 
}

不能調用更新：

updated_at: Sun Nov 27 2016 16:59:45 GMT-0800 (PST) 

的updated_at是自動填充字段。從請求中刪除它（打電話給你），它會起作用。
