Comment (by rach):
There is probably a better way to implement it and it's more in
implementation to illustrate the concept to unloose the relationship
between url routing and view lookup which are only one thing at this stage
in Django.
I m not fan of django-multiurl approach as it add one level of complexity
at the url configuration level, but I agree that could be implemented
following the same technique and wrap the urls into a container. I may
implement it for my next django project.
The usecases are numerous:
- Organize function base view to treat XHR request
- MultiForm submit on a same url
- Build easily api from function base view to handle PUT/POST/GET/DELETE
- create reusable condition to check url arguments without having to write
crazy regexp
- Call specific function base view base contentType
- Not getting a MethodNotAllowed when it's not what you want
- Call a specific view matter if the user is login or not ( ex: / ->
welcom or home)
...
More generics:
- Organize code from function base view and get rid off redundant logic
- Extending function base view without having to follow the Class Base
view model
