Ragtime is a Clojure library for migrating structured data in a way that's database independent. It defines a common interface for expressing migrations, much like Ring defines a common interface for expressing web applications.
Add the following dependency to your project file:
Ragtime needs three pieces of data to work:
A data store is an implementation of the
DataStore protocol, and
tells Ragtime how to record which migrations are applied to an
arbitrary store of data, such as a database.
Since 0.5.0, migrations are implementations of the
which has three methods:
id- returns a unique ID for the migration
run-up!- applies the migration to a database
run-down!- rolls back the migration in a database
Ragtime comes with a way of loading SQL migrations from files, and applying them to a SQL database.
