Today, I’d like to talk about loading your application’s seed data. Seed data? Seed data is anything that must be loaded for an application to work properly. An application needs its seed data loaded in order to run in development, test, and production. Examples include everything from an initial administrator account to small enumerations to huge amounts of data (one example of seed data given by a developer on the Ruby Users of Minnesota included every airport in the world). Seed data is mostly unchanging.

1 Migration Overview Migrations are a convenient way to alter your database schema over time in a consistent and easy way. They use a Ruby DSL so that you don't have to write SQL by hand, allowing your schema and changes to be database independent. You can think of each migration as being a new 'version' of the database. A schema starts off with nothing in it, and each migration modifies it to add or remove tables, columns, or entries. Active Record knows how to update your schema along this timeline, bringing it from whatever point it is in the history to the latest version. Haml to eRb/HTML online converter.

Rails For Beginners: All You Need To Know! The ActiveRecord module is based on the concept of database abstraction. As we mentioned in Chapter 1, database abstraction is a way of coding an application so that it isn't dependent upon any one database. Code that's specific to a particular database server is hidden safely in ActiveRecord, and invoked as needed. The result is that a Rails application is not bound to any specific database server software. Should you need to change the underlying database server at a later time, no changes to your application code should be required. Examples of code that differs greatly between vendors, and which ActiveRecord abstracts, include: Before I can show you the magic of ActiveRecord in action, though, we need to do a little housekeeping.
