knows the request. The request can be known in template context if the
view allows it (e.g.; uses a request context). Any model method that
depends on information from the request (like request.user) needs to be
passed that information as an argument). While you can't pass an argument
to a method being called using vanilla template syntax, you could write a
custom template tag, allowing, for example {% get_user_specific_price
model_instance %} . (Tags have access to the context, so you need not pass
it explicitly. Your view would still need to add request or request.user
to the context, unless you use a suitable template context processor to do
so.)
