Laravel5.4 - How to use POST method insert data to database

Question

I try to insert data to data.

  public function up()
            {
                Schema::create('request_song', function (Blueprint $table) {
                    $table->increments('id');
                    $table->string('song_name', 150);
                    $table->string('singer_name', 50);
                    $table->string('general_input', 200);

                    $table->timestamps();
                });
            }

RequestSongModel

class RequestSongModel extends Model
{
    protected $table = 'request_song';
    protected $fillable = [
        'id',
        'song_name',
        'singer_name'
    ];

}

Controller

    {
        $rule = [
            'song_name' => 'required',
            'singer_name' => 'required',

        ];

        $this->validate($request, $rule);
        $requestSong = RequestSongModel::created($request->all());

    }

Answer 1

How about this

$requestSong = RequestSongModel::created($request->all());

to

$requestSong = RequestSongModel::create($request->all());
