Methods

DatabaseUrl.to_active_record_hash(url = nil)
DatabaseUrl.to_active_record_url(hash)
DatabaseUrl.to_sequel_hash(url = nil)
DatabaseUrl.to_sequel_url(hash)

Get DATABASE_URL from config hash

You pass it a hash (string or symbol keys, doesn't matter) and it gives you a URL:

>> c = YAML.load_file('/path/to/config/database.yml')
=> {"development"=>{"adapter"=>"mysql2", "database"=>"myapp_development", "username"=>"root", "password"=>"password", "encoding"=>"utf8"}, "test"=>{"adapter"=>"mysql2", "database"=>"myapp_test", "username"=>"root", "password"=>"password", "encoding"=>"utf8"}, "production"=>{"adapter"=>"mysql2", "database"=>"myapp", "username"=>"myapp", "password"=>"XXX", "encoding"=>"utf8"}, "cucumber"=>{"adapter"=>"mysql2", "database"=>"myapp_cucumber", "username"=>"root", "password"=>"password", "encoding"=>"utf8"}}
>> DatabaseUrl.to_active_record_url c['development']
=> "mysql2://root:password@127.0.0.1/myapp_development?encoding=utf8"

Get config hash from DATABASE_URL

>> DatabaseUrl.to_active_record_hash('postgres://uuu:xxx@127.0.0.1:1234/abc')
=> {:adapter=>"postgres", :host=>"127.0.0.1", :port=>1234, :database=>"abc", :user=>"uuu", :password=>"xxx"}

If you omit the argument, it will try ENV['DATABASE_URL']
