Python Django: Accessing Google App Engine URL - Post then

I have something like this:

class CategoryPage (webapp.RequestHandler):
def get(self):
    ** DO SOMETHING HERE **
def post(self):
    ** DO SOMETHING HERE **
    ** RENDER THE SAME AS get(self)

The question is how, after processing the posted data, can I display the same information as the get (self) function?

Redirection, as others have shown, has some advantage, but it is a bit of a "heavy" approach. Alternatively, consider refactoring the rendering part into a separate helper method def _Render(self):

and just completing the methods get

and post

calling self.Render()

.

Call self.redirect (url) to redirect the user to the same page via GET. This way they won't accidentally resubmit the form if they hit refresh.

create_object(request, form_class=FormClass,
        post_save_redirect=reverse('-get-url-handler-',
                                   kwargs=dict(key='%(key)s')))

I am using the above django shortcut from shared views where you can specify a post save redirect get in your case. There are some more examples in this snippet. BTW, I assumed you are using django (helper or patch) with an application engine based on the title of the question. If you're using a patch for an application, check out the views.py view in the sample application myapp. The add_person handler does what you are looking for.

This is generally not a good idea as it will cause confusion. You should really do what you want and then redirect them to the get method.

Actually, your code is not Django, but webapp (Google mini - "framework"). Please read the Django documentation: http://docs.djangoproject.com/

Django generic views are only accessible with app-engine-patch. The assistant does not support them. You can see the app-engine-patch example project to learn more about Django on App Engine: http://code.google.com/p/app-engine-patch/
