In this hour, we discussed customizing models in the admin interface. You learned that by modifying the Admin class in your models, you can change how they look and behave in the admin interface.
The list_display attribute allows you to define what fields to display in a change list. The list_filter, search_fields, and date_hierarchy attributes allow you to limit the objects displayed in a change list. The fields attribute allows you to group fields under expandable and collapsible labels so that your object add and create forms are more readable.
You also learned how to use the edit_inline argument in ForeignKey field definitions so that multiple objects can be edited in the same form in the admin interface.
