- Exception view
- An exception view is a :Pyramid view callable which may be invoked when
an exception is raised during request processing.
- A Python “standard library”
logging module logger. See
http://docs.python.org/library/logging.html for more information about
Python standard library logging.
- A web framework.
- A bit of code that sits between the Pyramid router’s main request
handling function and the upstream WSGI component that uses Pyramid as
its ‘app’. The word “tween” is a contraction of “between”. A tween may
be used by Pyramid framework extensions, to provide, for example,
Pyramid-specific view timing support, bookkeeping code that examines
exceptions before they are returned to the upstream WSGI application, or
a variety of other features. Tweens behave a bit like WSGI ‘middleware’
but they have the benefit of running in a context in which they have
access to the Pyramid application registry as well as the Pyramid
rendering machinery. See the main Pyramid documentation for more
information about tweens.
