更可重用的方法:

class DefaultFilterMixIn(admin.ModelAdmin):
    def changelist_view(self, request, *args, **kwargs):
        from django.http import HttpResponseRedirect
        if self.default_filters:
            try:
                test = request.META['HTTP_REFERER'].split(request.META['PATH_INFO'])
                if test and test[-1] and not test[-1].startswith('?'):
                    url = reverse('admin:%s_%s_changelist' % (self.opts.app_label, self.opts.module_name))
                    filters = []
                    for filter in self.default_filters:
                        key = filter.split('=')[0]
                        if not request.GET.has_key(key):
                            filters.append(filter)
                    if filters:                        
                        return HttpResponseRedirect("%s?%s" % (url, "&".join(filters)))
            except: pass
        return super(DefaultFilterMixIn, self).changelist_view(request, *args, **kwargs)            

然后在你的 ModelAdmin 上定义一个 default_filters:

And then just define a default_filters on your ModelAdmin:

class YourModelAdmin(DefaultFilterMixIn):
    ....
    default_filters = ('snapshot__exact=0',)
