Rails Default Database

Tired of cp config/database.example.yml config/database.yml? Me too.
That’s why I wrote this Gem. Simply add this line to your Gemfile and
PostgreSQL, MySQL, or SQLite3 (depending on which of the 3 is in your
Gemfile) will be automatically configured with Rails defaults:

gem 'rails-default-database'

You can still override the defaults by creating config/database.yml.
Use rake db:config to create config/database.yml with the defaults
that would have been assumed.

The default database name is based on the name of the root directory of your
application. This can be overridden by setting
config.database_name = 'foo_%s' in config/application.rb, with %s being
a placeholder for the current environment name.

As in standard Rails, the DATABASE_URL environment variable takes
precedence when defined. However, in the test environment, Rails Default
Database will append _test to the database name (after stripping an optional
existing environment suffix), ensuring the development (or production!)
database is never clobbered. This enables storing your database configuration
in .env, if you so choose.
