Reset the database (purge all), then seed a database

Question

Is there a rake command to wipe out the data in the database tables?

How do I create a db:seed script to pre-fill data to my tables?

Answer 1

You can delete everything and recreate database + seeds with both:

1. rake db:reset: loads from schema.rb
2. rake db:drop db:create db:migrate db:seed: loads from migrations

Make sure you have no connections to db (rails server, sql client..) or the db won't drop.

schema.rb is a snapshot of the current state of your database generated by:

rake db:schema:dump
