Prioritizing Laravel 4 routes - php

Question

I have routes like this:
Route::group(array('before' => 'installed'), function() {
Route::group(array('before' => 'auth_admin', 'prefix' => 'admin'), function()
{
Route::group(array('prefix' => 'gag'), function() {
Route::get('/', 'Admin\\GagController#index');
Route::get('delete/{id}','Admin\\GagController#delete');
});
});
});
I need to prevent users from deleting content on my demo application. So I added the following piece of code before my actual routes.
if(App::environment() === 'demo')
{
Route::get('admin/gag/delete/{id}', function() {
die("You can't delete anything on demo application.");
});
}
//Actual routes are at the below.
However, it doesn't work when Route::get('delete/{id}','Admin\\GagController#delete'); is there. Somehow, Laravel ignores my if block and priorities this route. (Although if block is at the top.)
Looks like routes.php parses my if block after routes are parsed.
How can I make it so Laravel prioritizes my demo routes? I just want to restrict access to some features like this.
Ps. I don't want to add all the routes in if blocks. I just want the routes in my if block to be prioritized.

Route filters are better to do this sort of restrictions:
Route::filter('checkDemo', function()
{
if (App::environment() === 'demo')
{
return Redirect::to('home')->withMessage('You can''t delete anything on demo application.');
}
});
And set the filter to your route:
Route::group(array('prefix' => 'gag', 'before' => 'checkDemo'), function()
{
...
});
Or you can filter just that particular route:
Route::get('delete/{id}', array('before' => 'checkDemo', 'uses' => 'Admin\\GagController#delete'));
