Description (last modified by agustin bacigalup)

I'd like to contribute to Django by adding a shorcut, similar to django.shortcuts.redirect but also appends request's GET parameters. I found myself using it a lot, and I wonder if it's useful for the community. If so, should I fork Django on Github and submit a pull request?

def redirect_with_params(request, to, *args, **kwargs):
    """
    Same as `django.shortcuts.redirect` but recieves a `request` as first parameter.
    It preserves the GET parameters from the `request` in the URL redirected.
    """
    response = redirect(to, *args, **kwargs)
    url = response.url
    params = request.GET.urlencode()
    if params:
        url = "%s?%s" % (response.url, params)
    return response.__class__(url)

Hi Augustin,

If you look at RedirectView, you'll see the query_string attribute. It might be good to mirror the variable name there.

It also uses `request.META`'s `'QUERY_STRING`', which might save you a step:

        args = self.request.META.get('QUERY_STRING', '')
        if args and self.query_string:
            url = "%s?%s" % (url, args)

I can see how this might be a handy addition to a project. I'm not sure it merits an additional function in shortcuts. (It doesn't seem in the same order of utility as the existing methods. redirect() itself is 9 or 10 years old, so we've been living without this for a while...) I guess for me it's the sort of thing that can happily live in a blog post or a gist or a third-party package (if it were bundled up with other things).

Happy if you want to ask if there's appetite to include it on django-developers, but at this point I'll lean towards not. Thanks.
