Django
2008/07/28 @ 01:15I was thinking about using Django for one of my projects on GAE because it seems like a popular project and somewhat easy to use, but I'm not quite understanding yet why it's better to have helper functions rather than controller/handler classes like Pylons or GAE's normal WSGI handling has. With handler classes my controller might look like:
| from google.appengine.ext.webapp import RequestHandler | |
| class MainHandler(webapp.RequestHandler): | |
| def get(self): | |
| # Read data from BigTable here | |
| self.response.out.write(outputhtml) | |
| def post(self): | |
| # Write data to BigTable here | |
| #redirect back to the url | |
| self.redirect(self.request.url) |
Whereas the django helper function might look like
| from django.http import HttpResponse, HttpResponseRedirect | |
| def mainview(request): | |
| if request.method == 'POST': | |
| # Write to BigTable Here | |
| return HttpResponse(outputhtml) | |
| elif request.method == 'GET': | |
| # Read from BigTable Here | |
| return HTTPResponseRedirect(request.url) |
While the Django method might have the potential to have be a bit less verbose it feels like it would be harder to do things correctly, like factor code etc. I also don't really like the conditional checks to see what kind of HTTP method was used. So either I would need to split GETs and POSTs to separate urls or just live with the conditional checks.
Personally I feel better with the Pylons-ish controller/handler approach. Anyone have an opinion?
