I'm working on a REST API for which I implement common functionality using
decorators that I can add to the request methods, and part of that common
functionality is setting headers. It's a work in progress but this is the
general idea:
def serializecontent(method):
@wraps(method)
def wrapper(self, *args, **keys):
# Retrieve the data from the wrapped method
content = method(self, *args, **keys)
if not content is None:
# Serialize the data as requested
serializeddata = self.serialize(content)
# Set the content headers
# This may not be the best place to do this, particularly the
> content length.
self.setcontentlengthheader(serializeddata)
self.setcontenttypeheader()
return serializeddata
else:
return None
> return wrapper
class UserCollection(Collection):
>
@handleexceptions
> @requestmethod
> @setetag()
> @serializecontent
> @setlastmodified(determinelastmodified=_lastmodified)
> @conditionalresponse(determinelastmodified=_lastmodified)
> def GET(self):
> return Collection.GET(self)
# ...
Is that more or less hacky? :P It needs a lot of tidying up as it is at the
moment, and I'm probably sidestepping a lot of great functionality that
web.py provides, but the thing I was trying to avoid like yourself was
recreating the same standard functionality in each request method.

Kevin
