django template not resolving context variables

def test(request):
    itemgroups = ItemGroup.objects.all()
    t = get_template('test.html')
    c = {'itemgroups':itemgroups}
    return HttpResponse(t.render(c))

In Pycharms editing django template, the variables passed as context is not resolved(does not appear on auto-suggestion) when the view is set as above

def index(request):
    itemgroups = ItemGroup.objects.all()
    return render_to_response('main.html',{
        'itemgroups':itemgroups
    },
    context_instance=RequestContext(request))

however I found a way around to get the resolved variables in the template, that is by using render_to_response function to render template and context variables.

Is there a way to customize auto-suggestion rules for pycharms editor? thanks in advance!
