Python Falcon Framework: optional URI parameters

Question

Is there a way to define optional path parameters in the Falcon web framework? Currently, I'm declaring separate routes for modifying the same resource.

app.add_route('/users/', users_api_post)
app.add_route('/users/{id}', users_api_put)

PS: There's a similar question on SO for Flask framework.

Can't you just create two routes that would be handled by the same controller? — vishes_shell, Sep 07 '16 at 07:51

It seems that you are using different HTTP methods, so it seems simpler to use differente functions (on_put and on_post).

But if you are using the same HTTP method, this worked for me:

class EventsResource(object):
    def on_get(self, req, resp, app_id, timeanddate=None):
        if timeanddate:
            ...
        else:
            ...

app.add_route('/events/{app_id}', EventsResource())
app.add_route('/events/{app_id}/{timeanddate}', EventsResource())

Hope this helps...
