+1 to the 'abort()' and 'redirect()' APIs.
- -1 to added non-local majyk in the guts of the publisher. I think the
use case is better served by adding an exception-mapping decorator to
the funcitons which might raise. Something like::
from webob.exc import HTTPException
def returnRaised(wrapped):
def _wrapper(*argv, **kw):
try:
return wrapped(*argv, **kw)
except HTTPException, e:
return e
return _wrapper
View code would look like::
@returnRaised
def aview(request):
abort(401)
Tres.
