How do I override an admin template (e.g. admin/index.html) while at the same time extending it (see https://docs.djangoproject.com/en/dev/ref/contrib/admin/#overriding-vs-r
This site had a simple solution that worked with my Django 1.7 configuration.
FIRST: Make a symlink named admin_src in your project's template/ directory to your installed Django templates. For me on Dreamhost using a virtualenv, my "source" Django admin templates were in:
~/virtualenvs/mydomain/lib/python2.7/site-packages/django/contrib/admin/templates/admin
SECOND: Create an admin directory in templates/
So my project's template/ directory now looked like this:
/templates/
admin
admin_src -> [to django source]
base.html
index.html
sitemap.xml
etc...
THIRD: In your new template/admin/ directory create a base.html file with this content:
{% extends "admin_src/base.html" %}
{% block extrahead %}
{% endblock %}
FOURTH: Add your admin favicon-admin.ico into your static root img folder.
Done. Easy.
