(ragtime options)

Create a Ragtime component for handling migrations. Expects a dependency :db that has a key :spec containing a clojure.java.jdbc compatible db-spec map.

Takes the following options:

:resource-path - the resource path to find migration files :strategy - the Ragtime strategy (defaults to ragtime.strategy/raise-error) :reporter - the reporter function (defaults to ragtime.repl/default-reporter)

reload clj

(reload {:keys [resource-path] :as component})

Reload the migrations of a Ragtime component and return a new component.

rollback clj

(rollback component)

(rollback {:keys [datastore migrations reporter]} amount-or-id)

Rolls the dependent database back to a specific migration ID, or by a fixed number of migrations. If supplied with only one argument, the database is rolled back by only one migration.
