request.GET vs request.POST/Redirect/GET in django

问题

In dealing with forms with multiple input parameters and pagination, where user can choose any number of parameters (like a search form) which approach is better and why? receiving data straight from request.GET in one view or implementing a Post/Redirect/Get (2 views).

using Post/Redirect/Get, one can easily sanitize data using ModelForms builtin methods:

if request.method == 'POST': 
    form = MySearchForm(request.POST)
    if form.is_valid():
        cd = form.cleaned_data
        #do stuff with cd

How would you sanitize data using request.GET?

Why would you want to use request.GET instead of POST/Redirect/GET in such circumstances?

回答1:

That depends on what your form does. If you're creating/modifying data, use POST. Otherwise, use GET (see http://en.wikipedia.org/wiki/Hypertext_Transfer_Protocol#Request_methods).

You can still use form.cleaned_data with GET, you just have to pass request.GET to the form.
