Django Admin - change header 'Django administration' text

There is an easy way to set admin site header - assign it to current admin instance in urls.py like this

admin.site.site_header = 'My admin'

Or one can implement some header-building magic in separate method

admin.site.site_header = get_admin_header()

Thus, in simple cases there's no need to subclass AdminSite

As of Django 1.7 you don't need to override templates. You can now implement site_header, site_title, and index_title attributes on a custom AdminSite in order to easily change the admin site’s page title and header text. Create an AdminSite subclass and hook your instance into your URLconf:

admin.py:

from django.contrib.admin import AdminSite
from django.utils.translation import ugettext_lazy

class MyAdminSite(AdminSite):
    # Text to put at the end of each page's <title>.
    site_title = ugettext_lazy('My site admin')

    # Text to put in each page's <h1> (and above login form).
    site_header = ugettext_lazy('My administration')

    # Text to put at the top of the admin index page.
    index_title = ugettext_lazy('Site administration')

admin_site = MyAdminSite()

urls.py:

from django.conf.urls import patterns, include
from myproject.admin import admin_site

urlpatterns = patterns('',
    (r'^myadmin/', include(admin_site.urls)),
)

Update: As pointed out by oxfn you can simply set the site_header in your urls.py or admin.py directly without subclassing AdminSite:

admin.site.site_header = 'My administration'
