参数化错误Laravel

标签： php laravel laravel-4

我目前正在尝试将数据传递到我的问题和答案表中，但我收到此错误

  

类型错误：传递给Illuminate \ Database \ Grammar :: parameterize（）的参数1必须是数组类型，给定字符串，在

中调用

在我的控制器中运行此行时似乎正在发生

class question extends Model {

protected $fillable = [
    'questionnaire_id',
    'text'
];


public function questionnaire() {
    return $this->belongsTo('App\questionnaires');
}

public function answer() {
    $this->belongsToMany('App\answer');
 }
}

下面我包括我的模型，视图和控制器：

型号（问题） 

class answer extends Model {

protected $fillable = [
    'question_id',
    'answer'
];

public function answer() {
    return $this->belongsTo('App/Question');
 }
}

型号（答案） 

public function store(Request $request)
{
    $question = question::create($request->all());
    $answers = answer::create($request->all());
    $answers->question_id = $question->id;
    foreach ($answers as $answer) {
        $answers->answer = $answer;
        $answers->save();
    }

    $question->save();
    $answer->save();


    return view('/create-question', ['questionnaire'=>$question]);
}

此外，我还包括完整的堆栈跟踪，如果有人能告诉我如何修复或甚至指向正确的方向，我将非常感激。

class ViewController: UIViewController {

    func myFunction() {
        ...
    }
}

1 个答案:

答案 0 :(得分：0)

替换 $answers = answer::create($request->all());

$question->answers()->createMany($request->get('answer'));

请注意，您应该将答案的答案重命名为更有意义。
