Comment (by drho...@gmail.com):
I modified the above middleware so that is doesn't break admin's related
object popups. This method tracks popup query strings separately from
regular pages. This way you can use filters inside the popup windows as
well. Hope it helps someone else.
{{{
from django import http
# based on http://code.djangoproject.com/ticket/3777#comment:4
class FilterPersistMiddleware(object):
def process_request(self, request):
if '/admin/' not in request.path:
return None
if not request.META.has_key('HTTP_REFERER'):
return None
popup = 'pop=1' in request.META['QUERY_STRING']
path = request.path
query_string = request.META['QUERY_STRING']
session = request.session
if session.get('redirected', False):#so that we dont loop once
redirected
del session['redirected']
return None
referrer = request.META['HTTP_REFERER'].split('?')[0]
referrer = referrer[referrer.find('/admin'):len(referrer)]
key = 'key'+path.replace('/','_')
if popup:
key = 'popup'+path.replace('/','_')
if path == referrer: #We are in same page as before
if query_string == '': #Filter is empty, delete it
if session.get(key,False):
del session[key]
return None
request.session[key] = query_string
else: #We are are coming from another page, restore filter if
available
if session.get(key, False):
query_string=request.session.get(key)
redirect_to = path+'?'+query_string
request.session['redirected'] = True
return http.HttpResponseRedirect(redirect_to)
return None
}}}
