Hi all,
I started using web.py for programming web services and, although I'm
quite happy with the framework, I couldn't find an out-of-the-box
solution for what I was looking for. More specifically, I wanted to
select the appropriate representation for the service's resources in a
RESTful way, i.e. using the HTTP Accept header.
I didn't like this:
render_html = web.template.render('templates/html')
render_xml = web.template.render('templates/xml')
render_json = lambda **args: json.dumps(args)
class hello:
def GET(self, name):
if not name: name = 'world'
message = 'Hello, %s!'%name
accept_string = web.ctx.env['HTTP_ACCEPT']
mime = find_best_supported_mime(accept_string)
if mime=='application/html':
return render_html.hello(message)
elif mime=='application/xml':
return render_xml.hello(message)
elif mime=='application/json':
return render_json(message)
else:
raise web.internalerror('no representation for "%s"'%mime)
So I made it like this:
@mimerender.represent(
html = render_html.hello,
xml = render_xml.hello,
json = render_json)
def GET(self, name):
if not name: name = 'world'
message = 'Hello, %s!'%name
return {'message': message}
I've made the library open-source and posted it at
http://code.google.com/p/mimerender
Hope someone finds it useful, and I'll gladly receive all comments and
criticisms.
Best,
MartÃn
