Tapestry 5 Database Migration Utility

About Database Migrations

Database migrations let you create and alter your model in an organized and structured way.

This module is largely inspired by Ruby on Rails migrations.

A sample migration

This is an insight of what a couple of migrations can looks like.

@Version(20100510)
public class MyModel implements Migration
{
    public void up()
    {
        helper.createTable("users");
        helper.addPrimaryKey("users", "id", Types.INTEGER);
        helper.addColumn("users", "name", Types.VARCHAR);
        helper.addColumn("users", "password", Types.VARCHAR);
    }

    public void down()
    {
        helper.dropTable("users");
    }
}

@Version(20100511)
public class UsersDescription implements Migration
{
    public void up()
    {
        helper.addColumn("users", "description", Types.CLOB);
    }

    public void down()
    {
        helper.removeColumn("users", "description");
    }
}
