Extend/override Eloquent create method - Cannot make static method non static
提问by Marwelln
I'm overriding the create()Eloquent method, but when I try to call it I get Cannot make static method Illuminate\\Database\\Eloquent\\Model::create() non static in class MyModel.
我覆盖了create()Eloquent 方法，但是当我尝试调用它时，我得到Cannot make static method Illuminate\\Database\\Eloquent\\Model::create() non static in class MyModel.
I call the create()method like this:
我这样调用create()方法：
$f = new MyModel();
$f->create([
'post_type_id' => 1,
'to_user_id' => Input::get('toUser'),
'from_user_id' => 10,
'message' => Input::get('message')
]);
And in the MyModelclass I have this:
在MyModel课堂上我有这个：
public function create($data) {
if (!Namespace\Auth::isAuthed())
throw new Exception("You can not create a post as a guest.");
parent::create($data);
}
Why doesn't this work? What should I change to make it work?
为什么这不起作用？我应该改变什么才能使它工作？

As the error says: The method Illuminate\Database\Eloquent\Model::create()is static and cannot be overridden as non-static.
正如错误所说：该方法Illuminate\Database\Eloquent\Model::create()是静态的，不能被覆盖为非静态的。
So implement it as
所以实现它
class MyModel extends Model
{
public static function create($data)
{
// ....
}
}
and call it by MyModel::create([...]);
并调用它 MyModel::create([...]);
You may also rethink if the auth-check-logic is really part of the Model or better moving it to the Controller or Routing part.
您还可以重新考虑 auth-check-logic 是否真的是模型的一部分，或者更好地将其移动到控制器或路由部分。
UPDATE
更新
This approach does not work from version 5.4.* onwards, instead follow this answer.
这种方法从 5.4.* 版本开始不起作用，而是按照这个答案。
public static function create(array $attributes = [])
{
$model = static::query()->create($attributes);
// ...
return $model;
}

Probably because you are overriding it and in the parent class it is defined as static.
Try adding the word staticin your function definition:
可能是因为您覆盖了它，并且在父类中它被定义为static. 尝试static在函数定义中添加这个词：
public static function create($data)
{
if (!Namespace\Auth::isAuthed())
throw new Exception("You can not create a post as a guest.");
return parent::create($data);
}
Of course you will also need to invoke it in a static manner:
当然，您还需要以静态方式调用它：
$f = MyModel::create([
'post_type_id' => 1,
'to_user_id' => Input::get('toUser'),
'from_user_id' => 10,
'message' => Input::get('message')
]);
