php - Macroable.php 第 74 行 : Method save does not exist. Laravel 5.2 中的 BadMethodCallException

Question

你好，我是 Laravel 的新手，现在我遇到了这个错误 BadMethodCallException in Macroable.php line 74: Method save does does notence.

如果我var_dump(); die(); 所有输出，然后我得到了所有输出，但是当我使用 save 方法将结果保存到数据库中时，它给了我这个错误 save 方法不存在。我不知道我的代码哪里做错了。

请参阅路由 Controller 和 View 以获得正确的理解。预先感谢您。

Controller

public function td($id) {

    $tn = $this->t->getAllTn();
    $to = $this->t->getAllTo();

    $time = Carbon\Carbon::now(); // current time
    $time->toDateTimeString(); // converting time to string

    if((isset($_POST["n"]) && !empty($_POST["n"]))) {
        $tn->t_type_id = Input::get('options');
        $tn->d_id = $id;
        $tn->result = Input::get('message');
        $tn->date = $time;

        // var_dump($tn->date);
        // var_dump($tn->t_type_id);
        // var_dump($tn->d_id);
        // var_dump($tn->result);
        // die();

        Session::flash('message', 'Your tn has been added.');
        $tn->save();

    } else if((isset($_POST["o"]) && !empty($_POST["o"]))) {

        $to->d_id = $id;
        $to->outcome = Input::get('message');
        $to->date = $time->toDateTimeString();

        // var_dump($to->d_id);
        // var_dump($to->outcome);
        // var_dump($to->date = $time->toDateTimeString());
        // die();

        Session::flash('message', 'Your to has been added.');
        $to->save();
    }
    return redirect('/t');
}

接口(interface)实现

public function getAllTn() {
  return TN::all();
}

public function getAllTO(){
  return TO::all();
}

Answer 1

您实例化模型的方式是错误的。尝试这样的事情:

$to = new TO();

$to->d_id = $id;
$to->outcome = Input::get('message');
$to->date = $time->toDateTimeString();

$to->save();
