I hope someone here can suggest a good way of handling this situation.
We have an application that supports a given user profile view via two or
more possible URL patterns:
"/users/{username_regex}"
"/users/{userid_regex}"
To handle this within one route declaration, a `factory` is used:
config.add_route("user_focus", "/users/{user_identifier}",
factory=factory__useraccount)
The factory does regex on the `user_identifier` placeholder, and updates
the request matchdict with an extracted `user_name` or `user_id`. this
works perfect and allows us to avoid this:
config.add_route("user_focus_a", "/users/{username_identifier}")
config.add_route("user_focus_b", "/users/{userid_identifier}")
we also avoid using view_config to register 2 routes onto each callable
We've added some new functionality, and I'm having a problem figuring out
the best way to implement it.
users matching a particular new format of the `user_identifier` placeholder
need to respond to another route
there are essentially 4 potential patterns
config.add_route("usertype_a_focus_username",
"/users/{username_A_regex}")
config.add_route("usertype_a_focus_userid",
"/users/{userid_A_regex}")
config.add_route("usertype_b_focus_username",
"/users/{username_B_regex}")
config.add_route("usertype_b_focus_userid",
"/users/{userid_B_regex}")
ideally i'd love to simplify this into 2 routes, as they map to 2 views.
something like:
config.add_route("usertype_a_focus",
"/users/{usertype_a_identifier}", ...)
config.add_route("usertype_b_focus",
"/users/{usertype_b_identifier}", ...)
the problem with the approach is that `usertype_a_focus` grabs the route,
and the `factory` (to my knowledge) can only raise a not-found - not fail
the lookup and continue on to future patterns - so `usertype_b_focus` never
runs.
it looks like I could do this by running a regex in the placeholder, but
then I'm running it again in the factory to alter the matchdict. that will
also require duplicating an already complied regex into the pattern syntax
for the route. the app is large, so I'd like to avoid having to keep two
different regex patterns in sync with one another.
does anyone know if it is possible to better use factory, or implement some
other amazing Pyramid utility like predicates or something else in this
situation?
thank you all in advance.
