I made a first patch to demonstrate what I have in mind for routing all
the /etype/xxx urls.
It is the first step for removing the urlpublishing & controllers from
cubicweb and convert them to pyramid views.
The ultimate goal is to remove the need of bwcompat completely. For the
remaining hard to change cases (editcontroller I guess), we should be
able to directly call the controller from a pyramid view.
One of the things that will change with this new approach, and that
needs to be studied closely, is the way 'rql=' and 'vid=' can be passed
In pyramid, with traversal routes, the view name is passed in the url,
just after the context has been found (for ex, /etype/eid/edit -> the
As for the 'rql=' parameter, I think it should be restricted to a
specific route (/rql ?), which would be a traversal route too, allowing
various views to be used (/rql/etypelist, etc).
Actions will need some thinking too, static files should be more
Note that this is the start of breaking the urls compatibility, so we
must be careful, and try making the path as painless as possible.
