Django: admin chained filtering

Question

I want to do a chained filtering but it does not work

def queryset(self, request):
   qs = super(MaterialAdmin, self).queryset(request)
   if request.user.is_superuser:
       self.exclude = []
       return qs
   else:
       self.exclude = ['droits_acces', 'groupe']


   ff = qs.filter(groupe= request.user)
   gg = qs.filter(user=request.user)

   jj = qs.filter(user=request.user).filter(groupe= request.user)

   return jj

How to do ?

ff = [CC409, ST54]

gg = [Al2O3, BB79, CC409]

I would like to have

jj = [CC409, ST54, Al2O3, BB79]

You can use the Q object for complex queries.

from django.db.models import Q

...
    def queryset(self, request):
    ...
    return qs.filter(Q(groupe=request.user)|Q(user=request.user))
