Routing between forms without knowing the template

[danbolinson-bt]

I'm still getting my head around routing so bear with me...

I have multiple templates and multiple routings:

@routing.template("")
class Main(MainTemplate):
    # ...

@routing.template("alternate")
class AltMain(MainTemplate):
    # ...

@routing.route("")
class Home(HomeTemplate):
    # ...

@routing.route("", template="AltMain")
class AltHome(AltHomeTemplate):
    # ...

@routing.route("/page1"):
class Page1(Page1Template):
    # ...
    def on_click(self, **event_args):
        # Goal is to navigate to Page2 in the current template, but it seems like I need to figure out which 
        # template I'm actually in to construct the string for set_url_has
        template = get_template_from_hash() # some function that extracts the template in play
        routing.set_url_hash(f"{template}/page2"

@routing.route("/page2")
class Page2(Page2Template):
    # ...

Is there a better way? I'd love to be able to do something like:

@routing.route("/page1"):
class Page1(Page1Template):
    # ...
    def on_click(self, **event_args):
        routing.set_url_hash("/page2", use_current_template=True)

As I said, still getting my head around this so I might be missing some core concepts or available mechanisms. Thanks!

That starts to get into the realm of relative urls which isn't implemented in hash routing.

I have some future plans for this sort of thing. But not necessarily, for hash routing.

A current pattern might be

def get_base():
    pattern = routing.get_url_pattern()
    parts = pattern.split("/")
    if not parts:
        return ""
    return parts[0]

The idea for use_current_template is nice. And happy to think about implementing that as a feature request. Or look at a PR if you wanted to write one.
