Change page

As explained in Django in Action

A change page is a Django Admin page containing a form for editing an existing database object.

A change page is a Django Admin form for editing an existing database object. From the listing page, selecting an object opens its change page, where you can update that object's fields. section 5.1.3

A change page fits into Django Admin's standard CRUD flow:

• The listing page shows objects for a registered model. section 5.1.3
• Each listed object links to a change page. section 5.1.3
• The change page updates fields on the selected object. section 5.1.3

Registering the model behind the page

Registering the Musician model with an admin.ModelAdmin class gives Django Admin its default CRUD screens, including change pages. The administrator then opens /admin/, chooses a listed musician, and edits the object's fields. section 5.1.3
