Using doctrine in a custom task - doctrine

Question

I'm creating a task in a symfony 1.4 project, and I need to update some tables.
I've written :
<?php
class dataImportTask extends sfBaseTask
{
public function configure()
{
$this->namespace = 'data';
$this->name = 'import';
$this->addOptions(array(
new sfCommandOption('env', null, sfCommandOption::PARAMETER_REQUIRED, 'environment', 'dev'),
));
}
public function execute($arguments = array(), $options = array())
{
$databaseManager = new sfDatabaseManager(sfProjectConfiguration::getApplicationConfiguration('frontend', $options['env'], true));
$connection = $databaseManager->getDatabase()->getConnection();
}
}
(Following the example found on symfony-project.org)
But when I execute the task, symfony says : "Database "default" does not exist.". Why doesn't the task uses the dbname defined in databases.yml ?

Answer 1

It's a common problem when working with task. You have 2 options:
named your doctrine connection default in the database.yml
keep the same name in the database.yml and add an option on every tasks to retrieve the right database name.
For option #2, you have to add an option with the name (the one define in your database.yml) of your database and then change the way the getDatabase works:
In the database.yml:
all:
doctrine:
class: sfDoctrineDatabase
Based on the doctrine name above, add the option in your task:
<?php
class dataImportTask extends sfBaseTask
{
public function configure()
{
$this->namespace = 'data';
$this->name = 'import';
$this->addOptions(array(
new sfCommandOption('env', null, sfCommandOption::PARAMETER_REQUIRED, 'environment', 'dev'),
new sfCommandOption('connection', null, sfCommandOption::PARAMETER_REQUIRED, 'The connection name', 'doctrine'),
));
}
public function execute($arguments = array(), $options = array())
{
$databaseManager = new sfDatabaseManager(sfProjectConfiguration::getApplicationConfiguration('frontend', $options['env'], true));
$connection = $databaseManager->getDatabase($options['connection'])->getConnection();
}
}
