Django: Is there a way to set global views? For example enable data for a sidebar through all URLS

I am building a Django application that is a pretty basic blog, so far it has been wonderful. I got comments, tags etc up. But one thing is bugging me: I cant get the sidebar i want to work. I use the django.views.generic.date_based generic view and this is my urls.py for the blog:

    urlpatterns = patterns('django.views.generic.date_based',
        (r'(?P<year>\d{4})/(?P<month>[a-z]{3})/(?P<day>\w{1,2})/(?P<slug>[-\w]+)/$', 'object_detail',dict(info_dict, slug_field='slug',template_name='blog/detail.html')),

 (r'^(?P<year>\d{4})/(?P<month>[a-z]{3})/(?P<day>w{1,2})/(?P<slug>[-\w]+)/$', 'object_detail', dict(info_dict, template_name='blog/list.html')),

 (r'^(?P<year>\d{4})/(?P<month>[a-z]{3})/(?P<day>w{1,2})/$','archive_day',dict(info_dict,template_name='blog/list.html')),

 (r'^(?P<year>\d{4})/(?P<month>[a-z]{3})/$','archive_month', dict(info_dict, template_name='blog/list.html')),

 (r'^(?P<year>\d{4})/$','archive_year', dict(info_dict, template_name='blog/list.html')),

 (r'^$','archive_index', dict(info_dict, template_name='blog/list.html')),

)

When i use the URL with 'arc开发者_StackOverflow社区hive_index' passed i can easily print the latest entries for my sidebar, but when i enter a post i will use one of the top ones where only "object_detail" is availabe. This makes my sidebar entries dissapear. What is the best solution to this problem? Is there a way to make some objects available globally? Through views or otherwise.

People do things like that with template tags. The documentation for custom template tags might be helpful, and there's also a great little tutorial here.

Alternatively, you can use context processors - but that adds an overhead to every single request, which may not be necessary.
