Erm, I'm not sure, but from the looks of it your decorator doesn't do
anything.
It will retrieve a predicate, then it's called with a function to
decorate. This is a *module init*-time! But you then check for
authorization, and then simply return the function unmodified...
The decorator should look like this:
from decorator import decorator
def require(predicate):
@decorator
def check_authorization(func, *args, **kwargs):
environ = request.environ
try:
check_authorization(predicate, environ)
except NotAuthorizedError, e:
flash(e.errors, status="status_error")
raise HTTPUnauthorized()
return func(*args, **kwargs)
return check_authorization

Dunno much about hooks.
