| db:create Creates the database for the current RAILS_ENV environment. If RAILS_ENV is not specified it defaults to the development and test databases. | |
| db:create:all Creates the database for all environments. | |
| db:drop Drops the database for the current RAILS_ENV environment. If RAILS_ENV is not specified it defaults to the development and test databases. | |
| db:drop:all Drops the database for all environments. | |
| db:migrate Runs migrations for the current environment that have not run yet. By default it will run migrations only in the development environment. | |
| db:migrate:redo Runs db:migrate:down and db:migrate:up or db:migrate:rollback and db:migrate:migrate depending on the specified migration. I usually run this after creating and running a new migration to ensure the migration is reversable. | |
| db:migrate:up Runs the up for the given migration VERSION. | |
| db:migrate:down Runs the down for the given migration VERSION. |
