Override default queryset in Django admin

Question

One of my models has a deleted flag, which is used to hide objects globally:

class NondeletedManager(models.Manager):
    \"\"\"Returns only objects which ha         


        

Answer 1

The accepted solution works great for me but I needed a little bit more flexibility, so I ended up extending the changelist view to add in a custom queryset parameter. I can now configure my default queryset/filter as such and it can still be modified by using a different filter (get parameters):

def changelist_view(self, request, extra_context=None):
    if len(request.GET) == 0 :
        q = request.GET.copy()
        q['status__gt'] = 4
        request.GET = q
        request.META['QUERY_STRING'] = request.GET.urlencode()

    return super(WorksheetAdmin,self).changelist_view(request, extra_context=extra_context)
