No, you don't need to use the same template. You are just filling in
some data on every request using the context processor. Its like this:
1) Write a context processor that adds shopping cart info to every
context. Now it can be accessed via {{ cart.items }} or however you
set it up
2) Write templates to use these. For example, if you only want the
shopping cart info in, say, half of your pages, have those pages
extend a template that contains {{ cart.items }} in the header. For
the others, don't.
3) Alternatively, if you *don't* want shopping cart info in all of
your contexts, you can use the additional argument to RequestContext
for just those views where it is used. The docs reference an
"ip_address_processor" that is added this way.
And in answer to your questions:
a) I don't know if it is better to send your shopping cart data to
every template. That depends on your application.
b) Of course there is a way. It is included as request.session in
every view, if you have the session middleware activated. If this
solves your display questions, it is probably easier than creating a
custom processor anyway.
