Button with save and custom action in Admin

[Rob]

In Django 1.4 I am working on a small mailing app, and in the admin change page I would like to add a button called "send mailing". When the user presses the button the model should be saved first, en then redirected to a custom page to view and confirm the mailing before send.

I saw lots of snippets, custom actions etc. etc. but I cannot get it working.

I have add a custom change_form.html in /templates/admin/myapp and succesfully added a button. But how do I "tell" Django to do the two actions?

When I add name="_save" to the button the model is saved after pressing the custom button, but now I need a redirect to a custom page using the currect model.

I found a snippet which does everything I want (in case anybody runs into the same problem):
