Route pattern with field name

[Korko]

Hi,

In the routing system, we have the possibility to use variables (e.g. Route::get('/{draw}', ...)). We can also define a pattern to match those variables with Route::pattern('draw', ...).

In my routes I have both {draw:id} and {draw:hash} (using the HashId system) but I can't set a Route::pattern for the hash one.
If I set Route::pattern('draw', ...) it's defined for boths fields (id and hash) but if I define with Route::pattern('draw:hash', ...) it's ignored.

Upon further analyze, Symfony RouteCompiler uses \w+ ([A-Za-z0-9_]+) to get the variable name in the actual route (/{draw:hash}) so it's totally ignoring the field part.

The reason I'm using the field selector is to automatically use the route model binding (Draw::resolveRouteBinding) so I don't want to use custom names like drawId and drawHash.

Not sure how to implement that. Should we ask Symfony to add the ":" is the RouteCompiler regex or have a way to specify the field in the pattern match?

Thanks
