ModelAdmin.filter_horizontal By default, a ManyToManyField is displayed in the admin site with a <select multiple>. However, multiple-select boxes can be difficult to use when selecting many items. Adding a ManyToManyField to this list will instead use a nifty unobtrusive JavaScript “filter” interface that allows searching within the options. The unselected and selected options appear in two boxes side by side. See filter_vertical to use a vertical interface.

ModelAdmin.fields Use the fields option to make simple layout changes in the forms on the “add” and “change” pages such as showing only a subset of available fields, modifying their order, or grouping them into rows. For example, you could define a simpler version of the admin form for the django.contrib.flatpages.models.FlatPage model as follows: class FlatPageAdmin(admin.ModelAdmin): fields = ('url', 'title', 'content') In the above example, only the fields url, title and content will

ModelAdmin.exclude This attribute, if given, should be a list of field names to exclude from the form. For example, let’s consider the following model: from django.db import models class Author(models.Model): name = models.CharField(max_length=100) title = models.CharField(max_length=3) birth_date = models.DateField(blank=True, null=True) If you want a form for the Author model that includes only the name and title fields, you would specify fields or exclude like this: from dja

ModelAdmin.empty_value_display New in Django 1.9. This attribute overrides the default display value for record’s fields that are empty (None, empty string, etc.). The default value is - (a dash). For example: from django.contrib import admin class AuthorAdmin(admin.ModelAdmin): empty_value_display = '-empty-' You can also override empty_value_display for all admin pages with AdminSite.empty_value_display, or for specific fields like this: from django.contrib import admin class Auth

ModelAdmin.delete_selected_confirmation_template Path to a custom template, used by the delete_selected action method for displaying a confirmation page when deleting one or more objects. See the actions documentation.

ModelAdmin.date_hierarchy Set date_hierarchy to the name of a DateField or DateTimeField in your model, and the change list page will include a date-based drilldown navigation by that field. Example: date_hierarchy = 'pub_date' This will intelligently populate itself based on available data, e.g. if all the dates are in one month, it’ll show the day-level drill-down only. Note date_hierarchy uses QuerySet.datetimes() internally. Please refer to its documentation for some caveats when time
