Pyramid has the ability to handle complex authentication and authorization patterns. How to do so is a constant source of frustration for new users. This is a demo intended to showcase Pyramid's authorization capabilities. A lot of the demo focuses on URL Dispatch. If you are interested in traversal, do not despair as authorization via traversal is virtually indistinguishable from the object-level security demo and all of the concepts learned transfer over easily.

This demo is built around a wiki-style website to allows users to view and create pages. The supported URL structure is as follows:

/
/login
/logout

/users
/user/{login}

/pages
/create_page
/page/{title}
/page/{title}/edit

There are 3 different projects in this demo. Each project will add varying levels of functionality to this application:

0. Base Application

   Allow anyone to do anything. This is the base website we'll be starting with to demonstrate different levels of security.

1. Group-Level Security

   Allow users different privileges based on their 'group'.

   For example, users 'michael' and 'chris' are in the 'admin' group, while 'bob' is only in the 'user' group.

2. Object-Level Security

   Permit users access to all Page objects for which they are tagged as the owner, or permit a user to access only his or her User object.

   For example, 'michael' created the 'Demo' Page object, thus he can 'edit' and 'delete' it. But he cannot 'edit' or 'delete' the 'Pyramid' Page because he is not the owner.

Please reference the documentation in the docs/ directory for explanations of the different projects and levels of security. A rendered version of the documentation can be found at http://michael.merickel.org/projects/pyramid_auth_demo.
