使用for循环laravel插入多行

Question

SQLSTATE [42703]：未定义的列：7错误：关系“付款”的列“ 0”不存在\\ n第1行：插入“付款”（“ 0”，“ 1”，“ 2”，“ 3”， “ 4”，“ 5”，“ 6”，“ ... \\ n

    $payments = [];
    for ($x = 0; $x <= 12; $x++) {
      $payments[] = new Payments([
          'id' => Uuid::generate()->string,
          'number_of_months' => $request->number_of_months,
          'status' =>  $request->status,
          'date_of_expire' => $request->date_of_expire,
          'amount' => $request->amount,
          'unpaid_amount' =>  $request->unpaid_amount,
          'user_id' => $request->user_id,
          'date_of_payment' => $date->addMonths(1),
      ]);
    }

   DB::table('payments')->insert($payments);

模型

  public $incrementing = false;


  protected $fillable = [
      'id',
      'number_of_months',
      'date_of_payment',
      'date_of_expire',
      'amount',
      'unpaid_amount',
      'status',
      'user_id',
      'description'
  ];

当我尝试插入数据时出现此错误。 我不知道我在做什么错。

您为什么要尝试这样做？ 您可以将其保存在for循环中。

 for ($x = 0; $x <= 12; $x++) {
      Payments::create([
          'id' => Uuid::generate()->string,
          'number_of_months' => $request->number_of_months,
          'status' =>  $request->status,
          'date_of_expire' => $request->date_of_expire,
          'amount' => $request->amount,
          'unpaid_amount' =>  $request->unpaid_amount,
          'user_id' => $request->user_id,
          'date_of_payment' => $date->addMonths(1),
      ]);
  }

无需使用DB Facade即可插入数据库。 我猜您正在将payments表用于Payments模型。 如果不只是在您的Payments模型中添加以下行

protected $table = 'payments';
