Feature Request: delete_selected explicit option in admin

[sbrandt]

Hi,

according to this topic the only way to let the admin call delete() on every model using the delete_selected admin action is to copy the function, delete the queryset.delete()-method, add a obj.delete() in the loop, change the template path, copy the template and change the action name in it.

In addition, actions=[my_own_delete_selected] in the ModelAdmin class doesn't do the job, you must overwrite the get_actions method. That's much effort for such a simple task, especially because overwriting the delete() method is common as far as I know.

We could introduce a new admin option, let's say "ModelAdmin.delete_explicit" to do the job:

in django/contrib/actions/admin.py:45 (Django 1.3)

            for obj in queryset:

                obj_display = force_unicode(obj)

                modeladmin.log_deletion(request, obj, obj_display)

            queryset.delete()

            for obj in queryset:

                obj_display = force_unicode(obj)

                modeladmin.log_deletion(request, obj, obj_display)

                if modeladmin.delete_explicit:

                    obj.delete()

            if not modeladmin.delete_explicit:

                queryset.delete()     

Letting delete_explicit default to false, the change would be backwards compatible. 

Just a draft... What do you uthink?
