用代码块功能插入代码，请勿粘贴截图

model层代码
namespace App\model;

use Illuminate\Database\Eloquent\Model;

class crud extends Model
{
protected $table="count";
protected $primaryKey="id";
public $timestamps = true;
protected $guarded = [];

public  static  function Find($id)
{
    try{
        $res =self::select('*')->where('id', $id)->get();
        return $res;
    }catch (\Exception $exception){
        echo $exception->getMessage();
        return false;
    }

}
public  static  function Insert($name,$id)
{
    try{
        $res =self::create([
                'name' =>$name,
                'id' =>$id
            ]
        );
        return $res;
    }catch (\Exception $exception){
        echo $exception->getMessage();
        return false;
    }

}
public  static  function remove($id)
{
    try{
        $res =self::where('id', $id)->delete();
        return $res;
    }catch (\Exception $exception){
        echo $exception->getMessage();
        return false;
    }

}
public  static  function upda($name,$id)
{
    try{
        $res =self::where('id', $id)->update(
            [
                'name'=>$name,
                'id'=>$id
            ]
        );

        return $res;
    }catch (\Exception $exception){
        echo $exception->getMessage();
        return false;
