Rails Rake Database Operations

The operations that I most commonly use are db:create, db:migrate and db:reset. I was working with someone and found db:schema:load. I was pleasantly surprised when I came across this list of operations on Stack Overflow.

  • db:create creates the database for the current env
  • db:create:all creates the databases for all envs
  • db:drop drops the database for the current env
  • db:drop:all drops the databases for all envs
  • db:migrate runs migrations for the current env that have not run yet
  • db:migrate:up runs one specific migration
  • db:migrate:down rolls back one specific migration
  • db:migrate:status shows current migration status
  • db:migrate:rollback rolls back the last migration
  • db:forward advances the current schema version to the next one
  • db:seed (only) runs the db/seed.rb file
  • db:schema:load loads the schema into the current env’s database
  • db:schema:dump dumps the current env’s schema (and seems to create the db as well)
  • db:setup runs db:schema:load, db:seed
  • db:reset runs db:drop db:setup
  • db:migrate:redo runs (db:migrate:down db:migrate:up) or (db:migrate:rollback db:migrate:migrate) depending on the specified migration
  • db:migrate:reset runs db:drop db:create db:migrate
