How to hide the "save and add another" button in admin page?

[RLF_UNIQUE]

I have been trying all day. What I am doing is trying to have a model for an "about" page, which I want to limit to 1 item. It doesn't really make sense to have multiple "abouts". I've done everything described here

http://stackoverflow.com/questions/13101281/in-django-admin-how-can-i-hide-save-and-continue-and-save-and-add-another-butto

but can't get it to work, it works if in the ctx update I set show_save_and_add_another to false, but then the "save and add another" button doesn't show up for any model.

Please help.

You should override in your ModelAdmin the method has_add_permissions (docs here).
When it returns False, all the add buttons in the admin will be disabled for that particular Model.

Ah I see, give a user change permission but not add or remove? Then just use superaccount to make initial entry?

If your method ModelAdmin.has_add_permission() returns always False even a superuser can’t add the initial entry using the admin. But you can:

• Add the initial entry using the command line.
• Write a more complex has_add_permission method that checks if the request.user is a superuser or checks if  the initial entry already exists.

How about extending a template and issuing a CSS visibility ?
