I actually have the same question with the additional twist that I do not
know how long the path will be.
example url: '/bar/baz/8' or '/foo/3'. For any of these urls the resource
/bar/baz or /foo can be found through traversal,
but the last part of the url (8, 3 or any number) should be view_name.
Currently trying to solve this by catching the KeyError in __getitem__ and
manipulating the resource if key.isdigit().
But I would like to move manipulation of resource/model to another place.
Model/Resource is the abstration of data in the database,
therefore manipulation of resources after you've fetched them based on info
in url should be done elsewhere. (in my opinion)
I know it's an old topic, perhaps anyone may lead me to a newer solution
(google is your friend, but it only helps you when you already know what
you're looking for :)
Kind regards,
Dieter
