All get variables are automagically placed into the request.GET dictionary. In your example: http://mysite.com/manage/projects/1/milestones/?responsible__id__exact=1 Your variable `responsible__id__exact` would be obtained through the code: myVar = request.GET["responsible__id__exact"] or myVar = request.GET.get("responsible__id__exact", None)
The second method is recommended because it will set myVar to None if the GET variable is not specified. Hope this helps.
