$new = News::firstOrNew($request->except('_token'));
//dd($new);
$new->save();
return redirect()->to('/news/' . $new->id);

我dd打印的new对象是:
News {#268 ▼

0 => "new_title"
1 => "new_author"
2 => "new_body"

]

connection: "mysql"

attributes: array:3 [▼

"new_title" => "qwe"
"new_author" => "qi"
"new_body" => "wwwww"

]

}
但是myadmin数据库里却没有保存这条数据.
