global settings

[bfor...@socialistsushi.com]

Is there a place to set global values in a django project?
Specifically I want to set a base url, so I could do something like

<a href="{{BASE_URL}}/whatever">

I'd like to be able to set this somewhere so it can be easily changed
across installations.

Thanks

I posed just this question on #django last week. After going around and
around a few times, here's what I came up with. Its not exactly the
same thing, but it is working for me in a system where all the urls are
basically getting you to detail views of the different objects.

In myproject/settings/main.py add:
APP_URL_ROOT = 'myapp'

This is the url root for the site, (http://localhost:8000/myapp/). This
information lives in only this spot so if it changes to yourapp, I can
just change it in that one spot.

In myproject/settings/urls/main.py:
from django.conf.settings import APP_URL_ROOT
urlpatterns = patterns('',
(r'^%s/' % APP_URL_ROOT,
include('myproject.apps.myapp.urls.myapp')),
)

So I'm using the APP_URL_ROOT defined above to define the url base
here.

In my model file, for any object that I want to have a url for an
associated detail page:

def get_absolute_url(self):
from django.conf.settings import APP_URL_ROOT
return '/%s/%d' % (APP_URL_ROOT, self.id)

Then finally, in the templates, I can do:

<a href="{{ object.get_absolute_url }}"> - which would give
http://localhost:8000/myapp/1

or <a href="{{ object.get_absolute_url }}/whatever"> - which would
give http://localhost:8000/myapp/1/whatever

Hope that gives you some ideas. I'd love to hear how others have solved
this problem.

Thanks for the suggestion. I've implemented something similar.

What I'd really like, though is things that can be updated via the
admin interface (or whatever) and that I can use in the templates:

{% if global.foo %}
....
