A context processor is nothing more than a file. This file has a
function that takes an HttpRequest as an input and that returns a
dictionary with the variables you want to add to every template.
For example, in your case it could be:
add_variable(request):
the_variable=variable.objects.get(my_user__id=request.user.id)
return {'user_variable':the_variable}
Now, what you must add to TEMPLATE_CONTEXT_PROCESSORS is the path to
the function you just defined, as
'path.to.context_processor.add_variable'. That means that all
templates will have the {{ user_variable }} variable with the value
the_variable, dynamically assigned for each session.
Of course, you can add as many functions and files to your context_processor.
An example here:
http://svn.guindilla.eu:8000/complutense/eventos/context_processors.py
This adds to all templates the variables I need for a calendar that
appears in every web page of a site and can be dynamically modified.
in my settings.py I had to add:
TEMPLATE_CONTEXT_PROCESSORS = ("django.core.context_processors.auth",
"django.core.context_processors.debug",
"django.core.context_processors.i18n",
"complutense.eventos.context_processors.calendar")
Hope it helps,
G
