i'm interested in getting opinions on a small wsgi framework i
assembled from webob, sqlalchemy, genshi, and various code fragments i
found on the inter-tubes
here is the interesting glue - any comments / suggestions would be
much appreciated
------------------
the wsgi app
------------------
def application(environ, start_response):
path = environ.get('PATH_INFO', '').lstrip('/')
for regex, callback in urls:
match = re.search(regex, path)
if match:
environ['myapp.url_args'] = match.groups()
request = webob.Request(environ)
try:
return callback(request, start_response)
except Exception, ex:
start_response('500 Internal Server Error', [('Content-
Type', 'text/plain')])
return [traceback.format_exc()]
start_response('404 Not Found', [('Content-Type', 'text/plain')])
return ["Couldn't find the URL specified."]
----------------------------------
the controller decorator
----------------------------------
def web_decorator(filename, method='html'):
def decorator(target):
def wrapper(request, start_response):
#genshi TemplateLoader
template = loader.load(filename)
global config
try:
return_dict = target(request, start_response)
return_string = template.generate(**return_dict).render
(method)
config['database.Session'].commit()
except:
config['database.Session'].rollback()
raise
finally:
config['database.Session'].remove()
#TODO: alter 'Content-Type' per method being passed
start_response('200 OK', [('Content-Type', 'text/html')])
return [return_string]
return wrapper
return decorator
