Ralph Schindler's Blog: Dynamic Assertions for Zend

Ralph Schindler's Blog: Dynamic Assertions for Zend_Acl in ZF

Saturday, 12 September 2009 20:33

Ralph Schindler has a new post to his blog today looking at using dynamic assertions with the access control component (Zend_Acl) of the Zend Framework.

Over the last two years, I've seen a variety of duplicate issues come into the issue tracker, which stem from two fundamental flaws in Zend_Acl [...] In this article, we'll explore the API changes that alleviate these two problems, and we'll demonstrate how to leverage the Zend_Acl assertion system to create expressive, dynamic assertions that work with your applications models.

He mentions some of the backwards compatible changes that have been made to the ACL API including changes in the add() method and the ability to create Zend_Acl_Role and Zend_Acl_Resource objects explicitly. The rest of the post gives a great example of setting up users in a role, creating an action to test them against (can they work with a blog post?) and running a series of checks against the ACL component as a guest, contributor and publisher.

Distribution of the Original Works

You’re free to copy and redistribute the copylefted work — either by itself, or as part of a larger collection of works. All you have to do is (1) be honest - by clearly crediting me as the author, and only redistributing accurate copies of the original (But you don't REALLY have to :) hehe )- and (2) keep it free - by distributing the copy under the same copyleft license, and including either a copy of the license, or a reference to its URL (http://creativecommons.org/licenses/by-sa/1.0/legalcode).

You don’t have to copyleft your whole newsletter to reprint a single article of mine in it (although copylefting your whole newsletter is certainly worthwhile on its own merits). You only have to distribute the copy of my work under the copyleft terms. You’re also free to distribute abridged, translated, or otherwise edited copies of my works — but these count as derivative works, not copies of the original.

Derivative Works

You’re also free to make and distribute derivative works from the copylefted work (such as abridged or edited copies of original works, stories about characters introduced in the original works, etc.). All you have to do is (1) be honest — by clearly identifying your work as a derivative work, and clearly crediting me as the author of the original work on which it was based (But you don't REALLY have to do that either :) Hehehe) — and (2) keep it free — by distributing your derivative work as free content under the terms of the same copyleft license under which the original work was distributed. Please read the (The GNU General Public License ). Thank you very much.
