Is possible to add GET variables in a redirect ? (Without having to modifiy my urls.py)
If I do redirect('url-name', x)
I get HttpResponseRedirect('/my_long_url/%s/', x)
I don't have complains using HttpResponseRedirect('/my_long_url/%s/?q=something', x) instead, but just wondering...
Since redirect just returns an HttpResponseRedirect object, you could just alter that:
response = redirect('url-name', x)
response['Location'] += '?your=querystring'
return response
urldefrag if that's a possibility. Thanks for pointing out the potential error if you have an anchor in your url response.

I don't know of any way to do this without modifying the urls.py.

You might want to write a thin wrapper to make this easier. Say, custom_redirect
def custom_redirect(url_name, *args, **kwargs):
from django.core.urlresolvers import reverse
import urllib
url = reverse(url_name, args = args)
params = urllib.urlencode(kwargs)
return HttpResponseRedirect(url + "?%s" % params)
This can then be called from your views. For e.g.
return custom_redirect('url-name', x, q = 'something')
# Should redirect to '/my_long_url/x/?q=something'
We can import urlencode from django.
from django.utils.http import urlencode
get_args_str = urlencode({'q': 'something'})
Or we can just use unparsed get parameters string from starting request
get_args_str = request.META['QUERY_STRING']
HttpResponseRedirect('%s?%s' % (url, get_args_str))
x should be removed to make this work. Otherwise the contents of x are added as a body in the HTTP response when it should be empty.
I think it's worth noting that Django's RedirectView class has a built-in class attribute query_string which can be overridden or passed to as_view. If set to True, query_string will preserve the query string in the redirect. For example, you could put the following in urls.py:
path('example-redirect/',
RedirectView.as_view(url='https://example.com', query_string=True),
name='example_redirect')
