Foreign key's onDelete for dummies

By Romain Dorgueil on Thursday, July 10 2008, 23:55 - database

Any modern relational database engine supports the onDelete and onUpdate attributes on foreign keys. Propel and Doctrine of course allows to define it in the schema file (yaml or xml) and I believe it is important to explicitly set it.

Complex relations population in propel

By Romain Dorgueil on Thursday, January 31 2008, 23:47 - plugin

Since quite a bit, I've been faced with an annoying problem on every projects I use propel on. Propel builders only generates some specific cases selection methods, which consists of pretty ugly copy paste of the same code to populate the objects, and if your needs are not satisfied by the finite little number of propel handled cases, you'll have to either use pure SQL, or write a custom doSelect method. That seems okay at first sight, but it is not. In fact, you're about copypasting the propel generated method, and that's a rude violation of D.R.Y. principle.

I found no solutions during the two last years, but maybe things will change soon with the new sfPropelImpersonatorPlugin. This plugin is aiming at doing arbitrary object population based on informations provided by propel's introspection methods (DatabaseMap/TableMap/ColumnMap) to link populated objects.

The plugin is currently in very early stage, but is working pretty well for my needs, and I'm looking forward to know what others are thinking about it.

Symfony 1.0 is out!

By Romain Dorgueil on Monday, February 19 2007, 08:13 - release

Despite the DIGG side effects of which symfony project server suffered because of heavy traffic brought by the well known social bookmarking site's homepage anouncing symfony's first "stable" release, the long awaited 1.0 version is here!

For thoose who don't know it, Symfony is a MVC (Model-View-Component) PHP5 framework aiming to Rapid Application Development and good codinig practices like the DRY (Don't Repeat Yourself) principle. Their main contributors, french developpers from Sensio Labs Fabien Potencier and François Zaninotto have written a very good documentation book about it, that you can either buy at amazon (for thoose who like holding a real book), or download/read freely on the symfony project website as a PDF file.

Supported by a large community, you'll find support about symfony in diverse flavour, from the symfony forum to different languages mailing lists, going thru #symfony and #symfony-fr (for french developpers) on Freenode IRC network.

As the official release note is saying: At last, the long-awaited 1.0 stable version of symfony is just released. For all those who waited for the "stable" status to dive into symfony, the time has come.
