Ridgepole-rails provides two Rake tasks: ridgepole:export and ridgepole:apply They wrap ridgepole's ridgepole --export and ridgepole --apply respectively.

To export current schema of the database to Schemafile

rake ridgepole:export

To apply Schemafile to the database

rake ridgepole:apply

Some db tasks of Rails are replaced as follows:

• db:migrate invokes ridgepole:apply then ridgepole:export
• db:schema:dump invokes ridgepole:export
• db:schema:load invokes ridgepole:apply
• db:test:load invokes ridgepole:apply with first argument: test
• db:migrate:status, db:rollback and db:version are undefined

TODO: Some means not to replace these tasks above.

Add this line to your application's Gemfile:

gem 'ridgepole-rails'

And then execute:

$ bundle

Or install it yourself as:

$ gem install ridgepole-rails
