Django show object count on admin interface -
i have modified dashboard of dashboard.py file. there in have added custom module/widget called 'my widget' (haven't created myself rather appended child referring specific django app). code follows:
# append app list module "administration" self.children.append(modules.applist( _('administration'), models=('django.contrib.*',), )) self.children.append(modules.applist( _('my widget'), models=('flights.*',), children=[ ] )) flights django app has 3 models. dashboard looks following:
on widget want show count of users did log in today. count able (not on admin interface through view accessible via url testing purpose) following code snippet: user.objects.filter(last_login__startswith=timezone.now().date()).count()
how can show such count on widget?
the entire dashboard.py:
""" file generated customdashboard management command, contains 2 classes main dashboard , app index dashboard. can customize these classes want. activate index dashboard add following settings.py:: admin_tools_index_dashboard = 'api.dashboard.customindexdashboard' , activate app index dashboard:: admin_tools_app_index_dashboard = 'api.dashboard.customappindexdashboard' """ django.utils.translation import ugettext_lazy _ django.core.urlresolvers import reverse admin_tools.dashboard import modules, dashboard, appindexdashboard admin_tools.utils import get_admin_site_name admin_tools_stats.modules import dashboardcharts, get_active_graph class customindexdashboard(dashboard): """ custom index dashboard api.
