Boolean Container Parameters in Routes

Contributed by David Maicher in #30379

In Symfony apps, it's possible to use container parameters in the routes config. In Symfony 4.3 we improved this feature to also support boolean parameters, so you can do things like this:

        1
2
3
4
5
6
7
        /**
* @Route("/test", condition="%kernel.debug%")
*/
class TestController extends AbstractController
{
    // ...
}
    

Deprecated Some Router Options

Contributed by Tobias Schultze in #30249

The following Routing component config options have been deprecated and they will be removed in Symfony 5.0:

generator_base_class
generator_cache_class
matcher_base_class
matcher_cache_class

These classes are no longer used after some recent changes in the Routing code. Besides, using parameters to define the class to use is a practice that Symfony discouraged a few years ago.

Displayed the Route Conditions When Debugging

Contributed by Soufian Ez-Zantar in #29254

The debug:router command helps you debug routing issues by listing all the available routes and displaying all the details for a given route. In Symfony 4.3 we improved this command to also display the condition of the route (if defined):

        1
2
3
4
5
6
7
8
9
10
11
12
13
        $ php bin/console debug:router some_route_name
