Laravel 4 Optional Route Parameter

Question

I would like to know how to add an optional route parameter for a controller method:

Currently I have a route, shown below:

Route::get(\'devices/{cod

You can do this with Laravel 4 if you want, and it may be convenient for some JSON calls where a parameter not on the end of the URI may need to be empty.

The key is setting up a route specifically for the empty parameter. This route:

Route::get('devices//{area}','HomeController@getDevicesByArea');

will catch the URI "devices//myarea" and send it to:

public function getDevicesByArea($area) {...}

Where the code is supplied, the main route can catch that:

Route::get('devices/{code}/{area?}','HomeController@getDevicesByCode');

sending the code and optional area to:

public function getDevicesByArea($code, $area = '') {...}

This is not to say that swapping the parameters around in this example is not the better solution especially if the URL is going to be handled by a human. But I'm just adding for the record here that what was originally requested is possible, and can make some AJAX requests easier to deal with.
