As far as i can understand you want make an admin log-entry for the object you update using your custom action. I actually did something like that, purely as django does it. As its your custom action you can add this piece of code.
Edit: Call this function after your action finishes, or rather i should say, after you change the status and save the object.
def log_it(request, object, change_message):
"""
Log this activity
"""
from django.contrib.admin.models import LogEntry
from django.contrib.contenttypes.models import ContentType
LogEntry.objects.log_action(
user_id = request.user.id,
content_type_id = ContentType.objects.get_for_model(object).pk,
object_id = object.pk,
object_repr = change_message, # Message you want to show in admin action list
change_message = change_message, # I used same
action_flag = 4
)
# call it after you save your object
log_it(request, status_obj, "Status %s activated" % status_obj.pk)
You can always get which object you updated by fetching LogEntry object
log_entry = LogEntry.objects.filter(action_flag=4)[:1]
log_entry[0].get_admin_url()
Hope this helps.
