我从Laravel开始，希望了解更多关于使用错误处理的知识，特别是ModelNotFoundException对象.
<?php
class MenuController extends BaseController {
function f() {
try {
$menus = Menu::where('parent_id', '>', 100)->firstOrFail();
} catch (ModelNotFoundException $e) {
$message = 'Invalid parent_id.';
return Redirect::to('error')->with('message', $message);
}
return $menus;
}
}
?>
In my model:
<?php
use Illuminate\Database\Eloquent\ModelNotFoundException;
class Menu extends Eloquent {
protected $table = 'categories';
}
?>
当然，在我的例子中，"类别"中没有parent_id > 100的记录，这是我的单元测试.所以我想用ModelNotFoundException做点什么.
If I run http://example.co.uk/f in my browser I receive:
Illuminate \ Database \ Eloquent \ ModelNotFoundException
No query results for model [Menu].
the laravel error page - which is expected, but how do I redirect to my route 'error' with the pre-defined message? i.e.
<?php
// error.blade.php
{{ $message }}
?>
如果你能给我举个例子.
