問(wèn)題描述

我正在嘗試將多行保存到一個(gè)表中，但是，我遇到了一個(gè)質(zhì)量分配錯(cuò)誤.

I am trying to save multiple rows to a table, however, I am presented with a Mass Assignment Error.

錯(cuò)誤是:IlluminateDatabaseEloquentMassAssignmentExceptioncriteria_id

$criteria->save();

    $criteria_id = $criteria->id;

     foreach(Input::get('bedrooms') as $bedroom){
        $new_bedroom=array(
            'criteria_id' => $criteria->id,
            'bedroom' => $bedroom,
            );
        $bedroom = new Bedroom($new_bedroom);
        $bedroom->save();
    }

我的數(shù)據(jù)庫(kù)結(jié)構(gòu)是:

所以沒(méi)有任何不正確的拼寫(xiě).criteria_id 來(lái)自最近保存的標(biāo)準(zhǔn)的變量(參見(jiàn)上面 forloop 的代碼).

so there isn't any incorrect spelling. The criteria_id comes from the variable from the recently saved criteria (see code above forloop).

任何幫助將不勝感激.

推薦答案

為了能夠通過(guò)將屬性傳遞給模型的構(gòu)造函數(shù)來(lái)設(shè)置屬性，您需要在 $fillable 陣列.如文檔

To be able to set properties by passing them to the model's constructor, you need to list all the properties you need in the $fillable array. As mentioned in the Docs

class Bedroom extends Eloquent {
    protected $fillable = array('criteria_id', 'bedroom');
}

如果需要，您也可以使用 create 方法.它創(chuàng)建了一個(gè)新模型并直接保存:

Also you can use the create method if you want. It creates a new model and saves it directly:

foreach(Input::get('bedrooms') as $bedroom){
    $new_bedroom=array(
        'criteria_id' => $criteria->id,
        'bedroom' => $bedroom,
        );
    $bedroom = Bedroom::create($new_bedroom);
}
