Pecan

Pecan focuses on an app or website's relation to HTTP requests, unlike classic frameworks that deal with sessions, databases and user interactions.

In this way it's a low-level Python framework, but one more powerful than classic solutions because it allows developers to build more efficient and performance-based apps instead.

Features:

• Various security features included
• Template language support
• JSON support
• Object-dispatch for easy routing (via WSGI)
• REST-style controllers
• Easy configuration
• Extensible codebase
• Documentation

What is new in this release:

• For HTTP POSTs, map JSON request bodies to controller keyword arguments.
• Improved argspec detection and leniency for wrapped controllers.
• When path arguments are incorrect for RestController, return HTTP 404, not 400.
• When detecting non-content for HTTP 204, properly catch UnicodeDecodeError.
• Fixed a routing bug for generic subcontrollers.
• Fixed a bug in generic function handling when context locals are disabled.
• Fixed a bug that mixes up argument order for generic functions.

What is new in version 0.6.0:

• Added better support for hook composition via subclassing and mixins. For more information, see :ref:`attaching_hooks`.
• Added support for specifying custom request and response implementations at the WSGI application level for people who want to extend the functionality provided by the base classes in webob.
• Pecan controllers may now return an explicit webob.Response instance to short-circuit Pecan's template rendering and serialization.
• For generic methods that return HTTP 405, pecan now generates an Allow header to communicate acceptable methods to the client.
• Fixed a bug in adherence to RFC2616: if an exposed method returns no response body (or namespace), pecan will now enforce an HTTP 204 response (instead of HTTP 200).
• Fixed a bug in adherence to RFC2616: when pecan responds with HTTP 204 or HTTP 304, the Content-Type header is automatically stripped (because these types of HTTP responses do not contain body content).
• Fixed a bug: now when clients request JSON via an Accept header, webob HTTP exceptions are serialized as JSON, not their native HTML representation.
• Fixed a bug that broke applications which specified default_renderer = json.

What is new in version 0.5.0:

• This release adds formal support for pypy.
• Added colored request logging to the pecan serve command.
• Added a scaffold for easily generating a basic REST API.
• Added the ability to pass arbitrary keyword arguments to pecan.testing.load_test_app.
• Fixed a recursion-related bug in the error document middleware.
• Fixed a bug in the gunicorn_pecan command that caused threading.local data to leak between eventlet/gevent green threads.
• Improved documentation through fixes and narrative tutorials for sample pecan applications.

What is new in version 0.3.2:

• Made some changes to simplify how pecan.conf.app is passed to new apps.
• Fixed a routing bug for certain _lookup controller configurations.
• Improved documentation for handling file uploads.
