Purge or recreate a Ruby on Rails database

Question

I have a dev Ruby on Rails database full of data. I want to delete everything and rebuild the database. I\'m thinking of using something like:

rake db:recrea         


        

Answer 1

3 options, same result:

1. All steps:

  $ rake db:drop           # deletes the database for the current env
  $ rake db:create         # creates the database for the current env
  $ rake db:schema:load    # loads the schema already generated from schema.rb / erases data
  $ rake db:seed           # seed with initial data

2. Reset:

  $ rake db:reset          # drop / schema:load / seed

3. Migrate:reset:

  $ rake db:migrate:reset  # drop / create / migrate
  $ rake db:seed

Notes:

• If schema:load is used is faster than doing all migrations, but same result.
• All data will be lost.
• You can run multiple rakes in one line.
• Works with rails 3.
