Symfony2, working with Doctrine entities
Database interaction with Doctrine 2
Let's see some commands and snippet to interact with Doctrine2. If you use Netbeans IDE, you'll see how easy is to call the entityManager and other objects of this ORM. But remember to put all queries on your model and keep the controller functions as clean as you can.
Doctrine is integrated with Symfony but I've had some problems using MySQL. Set your connection parameters is easy but I suggest to set enum annotations on your configurations. Check out this question and the second answer on StackOverflow.
Import XML doctrine files from an existing database to your bundle:
php app/console doctrine:mapping:import --force AcmeApplicationBundle xml
Generate PHP entities files on your src dir of your bundle. I prefer to use only a bundle to store entities. It's faster when you want to update a single or all of them.
php app/console doctrine:mapping:convert annotation ./src
Use this command to generate a single entity:
php app/console doctrine:generate:entity
Generate getters and setters:
php app/console doctrine:generate:entities AcmeApplicationBundle
MySQL Year field type
Doctrine has problems, one of these is working with a MySQL date year field type. Symfony (and even Zend) apps don't work when you select these field types. Solution: check out this question on StackOverflow. The last answer worked for me too, update the notation with this one on your field name:
* @var \Year
* @ORM\Column(name="year_born", columnDefinition="YEAR", nullable=false)
