Symfony 3 routing with slug. Route with last slash without slug shows 404 page

Question

I've started using Symfony. I was trying to set up routing with slugs and had a problem.

When I enter no slug and no last slash site.me/lucky/number it's ok. But when I enter no slug with lash slash site.me/lucky/number/ I get 404 page. I found a workaround for it with additional "root" route, it can be seen in my routing file below.

Is it possible to use a single route entry? Is it possible to use multiple routes for the same action? Something like creating a link to a single route entry configured, so I don't have to make similar changes in many route entries.

I use php built-in server on ubuntu 16.

<!-- routing.xml -->
<?xml version="1.0" encoding="UTF-8" ?>
<routes xmlns="http://symfony.com/schema/routing"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://symfony.com/schema/routing
    http://symfony.com/schema/routing/routing-1.0.xsd">
    <route id="homepage" path="/">
        <default key="_controller">AppBundle:Default:index</default>
    </route>
    <route id="lucky_number_root" path="lucky/number/">
        <default key="_controller">AppBundle:Lucky:number</default>
        <default key="max">100</default>
    </route>
    <route id="lucky_number" path="lucky/number/{max}">
        <default key="_controller">AppBundle:Lucky:number</default>
        <default key="max">100</default>
        <requirement key="max">\d+</requirement>
    </route>
</routes>

Answer 1

Have you tried changing your routing.xml file to something like this:

<route id="lucky_number" path="/lucky/number/{max}/">
  <default key="_controller">AppBundle:Lucky:number</default>
  <default key="max">100</default>
  <requirement key="max">\d+</requirement>
</route>

I think that might work - try it. Just added the backslash at the end.

EDIT #2 NOTE: It was missing a backslash in front - try that

Answer 2

make max parameter optional <requirement key="max">\d*</requirement>

<!-- routing.xml -->
<?xml version="1.0" encoding="UTF-8" ?>
<routes xmlns="http://symfony.com/schema/routing"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://symfony.com/schema/routing
    http://symfony.com/schema/routing/routing-1.0.xsd">
    <route id="homepage" path="/">
        <default key="_controller">AppBundle:Default:index</default>
    </route>
    <route id="lucky_number_root" path="lucky/number/">
        <default key="_controller">AppBundle:Lucky:number</default>
        <default key="max">100</default>
    </route>
    <route id="lucky_number" path="lucky/number/{max}">
        <default key="_controller">AppBundle:Lucky:number</default>
        <default key="max">100</default>
        <requirement key="max">\d*</requirement>
    </route>
</routes>

also you can remove lucky_number_root route in this case
