Symfony2 – Franz Jordán 2011
A list of available command will print out, many of which start with the doctrine: prefix. You can
find out more information about any of these commands (or any Symfony command) by running
thehelp command. For example, to get details about the doctrine:database:create task, run:
php app/console help doctrine:database:create
Some notable or interesting tasks include:
doctrine:ensure-production-settings - checks to see if the current environment is
configured efficiently for production. This should always be run in the prod environment:
• php app/console doctrine:ensure-production-settings --env=prod
doctrine:mapping:import - allows Doctrine to introspect an existing database and
create mapping information. For more information, see How to generate Entities from an
Existing Database.
doctrine:mapping:info - tells you all of the entities that Doctrine is aware of and
whether or not there are any basic errors with the mapping.
doctrine:query:dql and doctrine:query:sql - allow you to execute DQL or SQL
queries directly from the command line.
To be able to load data fixtures to your database, you will need to have
theDoctrineFixturesBundle bundle installed. To learn how to do it, read the
"DoctrineFixturesBundle" entry of the documentation.
Summary
With Doctrine, you can focus on your objects and how they're useful in your application and
worry about database persistence second. This is because Doctrine allows you to use any PHP
object to hold your data and relies on mapping metadata information to map an object's data to
a particular database table.
And even though Doctrine revolves around a simple concept, it's incredibly powerful, allowing
you to create complex queries and subscribe to events that allow you to take different actions as
objects go through their persistence lifecycle.
For more information about Doctrine, see the Doctrine section of the cookbook, which includes
the following articles:
DoctrineFixturesBundle
Doctrine Extensions: Timestampable: Sluggable, Translatable, etc.
