Many applications are based on data stored in a database and offer an interface to access it. Symfony automates the repetitive task of creating a module providing data manipulation capabilities based on a Propel object. If your object model is properly defined, symfony can even generate an entire site administration automatically. This chapter describes the use of the administration generator, which is bundled with the Propel plugin. It relies on a special configuration file with a complete syntax, so most of this chapter describes the various possibilities of the administration generator.
