In order to replace delete_selected I do the following:

Copy the function <code>delete_selected</code> from <code>contrib/admin/actions.py</code> to your <code>admin.py</code> and rename it. Also copy the template <code>contrib/admin/templates/delete_selected_confirmation.html</code> to your template directory and rename it. Mine looks like this:

<pre><code>def reservation_bulk_delete(modeladmin, request, queryset):
 """
 Default action which deletes the selected objects.
 This action first displays a confirmation page whichs shows all the
 deleteable objects, or, if the user has no permission one of the related
 childs (foreignkeys), a "permission denied" message.

 Next, it delets all selected objects and redirects back to the change list.
 """
 opts = modeladmin.model._meta
 app_label = opts.app_label

 # Check that the user has delete permission for the actual model
 if not modeladmin.has_delete_permission(request):
 raise PermissionDenied

 # Populate deletable_objects, a data structure of all related objects that
 # will also be deleted.

 # deletable_objects must be a list if we want to use '|unordered_list' in the template
 deletable_objects = []
 perms_needed = set()
 i = 0
 for obj in queryset:
 deletable_objects.append([mark_safe(u'%s: &lt;a href="%s/"&gt;%s&lt;/a&gt;' % (escape(force_unicode(capfirst(opts.verbose_name))), obj.pk, escape(obj))), []])
 get_deleted_objects(deletable_objects[i], perms_needed, request.user, obj, opts, 1, modeladmin.admin_site, levels_to_root=2)
 i=i+1

 # The user has already confirmed the deletion.
 # Do the deletion and return a None to display the change list view again.
 if request.POST.get('post'):
 if perms_needed:
 raise PermissionDenied
 n = queryset.count()
 if n:
 for obj in queryset:
 obj_display = force_unicode(obj)

 obj.delete()

 modeladmin.log_deletion(request, obj, obj_display)
 #queryset.delete()
 modeladmin.message_user(request, _("Successfully deleted %(count)d %(items)s.") % {
 "count": n, "items": model_ngettext(modeladmin.opts, n)
 })
 # Return None to display the change list page again.
 return None

 context = {
 "title": _("Are you sure?"),

 "deletable_objects": deletable_objects,

 return render_to_response(modeladmin.delete_confirmation_template or [

 "admin/%s/reservation_bulk_delete_confirmation.html" % app_label,
 "admin/reservation_bulk_delete_confirmation.html"
 ], context, context_instance=template.RequestContext(request))
</code></pre>

As you can see I commented out

<pre><code>queryset.delete()
</code></pre>

and rather use:

<pre><code>obj.delete()
</code></pre>

That's not optimal yet - you should apply something to the entire queryset for better performance.

In admin.py I disable the default action delete_selected for the entire admin site:

<pre><code>admin.site.disable_action('delete_selected')
</code></pre>

Instead I use my own function where needed:

<pre><code>class ReservationAdmin(admin.ModelAdmin):
 actions = [reservation_bulk_delete, ]
</code></pre>

In my model I define the <code>delete()</code> function:

<pre><code>class Reservation(models.Model):
 def delete(self):
 self.status_server = RESERVATION_STATUS_DELETED
 self.save()
</code></pre>

It disables the default delete action for current AdminForm only.

<pre><code>class FlowAdmin(admin.ModelAdmin):

 actions = super(MyModelAdmin, self).get_actions(request)
