django-admin-extra-buttons

django-admin-extra-buttons

This is a full rewriting of the original django-admin-extra-url. It provides decorators to easily add custom buttons to Django Admin pages and/or add views to any ModelAdmin

It allows easy creation of wizards, actions and/or links to external resources as well as api only views.

Three decorators are available:

• button() to mark a method as extra view and show related button
• link() This is used for "external" link, where you don't need to invoke local views.
• view() View only decorator, this adds a new url but do not render any button.
• choice() Menu like button, can be used to group multiple @views().

Install
