Migrations are used to create and/or edit the database structure. To generate a new migration file, use this command:
php vendor/bin/doctrine-migrations migrations:generateIt creates a PHP file like this one /data/doctrine/migrations/Version20240627134952.php that can then be edited in the IDE.
You can add new queries in:
public function up - these are executed when the migration is run.public function down - these are optional queries that undo the above changes.This example creates a new column named test.
Add this in public function up:
$this->addSql('ALTER TABLE admin ADD test VARCHAR(255) NOT NULL');And its opposite in public function down:
$this->addSql('ALTER TABLE admin DROP test');
