how to obtain all values of a multi-valued key from Django's request.GET QueryDict

Question

The Django docs say at http://docs.djangoproject.com/en/dev/ref/request-response/#django.http.QueryDict.iteritems thatQueryDict.iteritems() uses the same last-value

Answer 1

This should work:

mstring = []
for key in request.GET.iterkeys():  # "for key in request.GET" works too.
    # Add filtering logic here.
    valuelist = request.GET.getlist(key)
    mstring.extend(['%s=%s' % (key, val) for val in valuelist])
print '&'.join(mstring)
