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:recreate 

Is this possible?

Answer 1

I know two ways to do this:

This will reset your database and reload your current schema with all:

rake db:reset db:migrate 

This will destroy your db and then create it and then migrate your current schema:

rake db:drop db:create db:migrate 

All data will be lost in both scenarios.

Answer 2

On Rails 4, all needed is

$ rake db:schema:load 

That would delete the entire contents on your DB and recreate the schema from your schema.rb file, without having to apply all migrations one by one.
