How to load objects from model on server start up?

I store my sites navigation menu in database. I want to load all objects in the list once I launch my server, but I haven’t got idea how to do it. I really need to do it, because it will be problem in future to load data from database in views to display 开发者_如何学Cmenu.

I tried to put loading code in settings.py, but there was an error, and in views after imports, but there was no effect.

I think you need Template context processors.

Here is a nice tutorial by James Bennett on that:

Well, I'm very new to django, and maybe I'm wrong, but I think you are looking for something like caching. Read the docs, and decide whether is it fits you or not.

You can cache just a part of your view:

https://docs.djangoproject.com/en/1.3/topics/cache/#template-fragment-caching

surround your navigation bar like this:

{% cache 500 navbar %}
   ... put your navbar code
{% endcache %}

and ensure to have

{% load cache %}

at the top of your template or the base template.
