/**
|
||
|
|
* 404 (Not Found) Handler
|
||
|
|
*
|
||
|
|
* Usage:
|
||
|
|
* return res.notFound();
|
||
|
|
* return res.notFound(err);
|
||
|
|
* return res.notFound(err, 'some/specific/notfound/view');
|
||
|
|
*
|
||
|
|
* e.g.:
|
||
|
|
* ```
|
||
|
|
* return res.notFound();
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* NOTE:
|
||
|
|
* If a request doesn't match any explicit routes (i.e. `config/routes.js`)
|
||
|
|
* or route blueprints (i.e. "shadow routes", Sails will call `res.notFound()`
|
||
|
|
* automatically.
