No route for HTTP request by capitalized first letter

tomcat4x

Hi,

why is there no route when i capitalize the first letter in the presenter part of the url?

http://localhost/…www/homepage is working but http://localhost/…www/Homepage throws a Nette\Application\BadRequestException #404

the only route is:

$router[] = new Route(‘<presenter>/<action>[/<id>]’, ‘Homepage:default’);

So i expected that both calls would redirect me to the homepage presenter. Why not?

Tested with the default sandbox of nette 2.3.7

Hey,

David wrote about this here (https://phpfashion.com/…o-url-stejne). You can try use translator, article is czech.

Short version with example:

https://en.wikipedia.org/wiki/Acid
https://en.wikipedia.org/wiki/ACID

These two URLs arent same! So homepage & Homepage arent same as well. I guess Nette expect small first lette for presenter, otherwise throw exception. You can define custom route like this:

$router[] = new Route(‘Homepage/<action>[/<id>]’, ‘Homepage:default’);

That for an apache these two urls arent the same is clear.

but in nette i thought that <presenter> in routing covers all requests like

http://localhost/homepage, http://localhost/homepage1, http://localhost/homepage2…

regardless of capitalized letters.

But as you say, nette seems to expect all letters uncapitalized. Also hOmepage throws an error.

You can always implement your own solution. Maybe this help https://doc.nette.org/…tion/routing#….

Also I found this https://doc.nette.org/…tion/routing#…, so regular should be insensitive (https://api.nette.org/…ute.php.html#…).

But here David wrote about case-sensitive presenters (https://phpfashion.com/…sku-citlivka), then flag lose purpose and mb we need flag CASE_INSENSITIVE (terrible name:)).

Sorry but i cant speak czech.

I had a look at the source code of router.php and it seems that the flag CASE_SENSITIVE has no more effect. It is depreceated. A flag CASE_INSENSITIVE it not present. So someone should revise the documentation.

in the style array, which is responsible for parsing the pattern <presenter> is following code:

	'presenter' => array(
			self::PATTERN => '[a-z][a-z0-9.-]*',
			self::FILTER_IN => array(__CLASS__, 'path2presenter'),
			self::FILTER_OUT => array(__CLASS__, 'presenter2path'),

So capitalized chars wont be matched. The only way is to modify the router.php to somting like that:

	'presenter' => array(
			self::PATTERN => '[A-Za-z][A-Za-z0-9.-]*',
			self::FILTER_IN => array(__CLASS__, 'path2presenter'),
			self::FILTER_OUT => array(__CLASS__, 'presenter2path'),

But because of updates it makes no sense to change a core file of nette. So i have to live with lowercase letters in the url. I was just wondered that i got a no route error. I expected a no presenter error if nette makes a difference between upper and lower case.

Yeah, I know. But sometimes you can translate article in browser. :)

You can define your own FILTER_IN/OUT at app/router/RouterFactory – something really simple like strtolower- so hOmepAge → will be homepage. And then you get rid off warnings about Case sensitive URL. But best solution IMHO is using lowercase letters.

FILTER IN/OUT does not work in this case, because the exception is thrown before ther first filter is executed. But i saw in the source code that you can overwrite the pattern in the route definition

			$router[] = new Route('<presenter=Homepage>/<action=default>', array(
			'presenter' => array(
		Route::PATTERN => '[A-Za-z0-9.-]*',
		Route::FILTER_IN => function($presenter) {
		return ucfirst(strtolower($presenter));
		},
	),
		));

now all presenter calls like hompage, Homepage, HOMEpage … will be processed by the HomepagePresenter.
