class ActiveRecord::DatabaseConfigurations::UrlConfig

A UrlConfig object is created for each database configuration entry that is created from a URL. This can either be a URL string or a hash with a URL in place of the config hash.

A URL config:

postgres://localhost/foo

Becomes:

#<ActiveRecord::DatabaseConfigurations::UrlConfig:0x00007fdc3238f340
  @env_name="default_env", @spec_name="primary",
  @config={"adapter"=>"postgresql", "database"=>"foo", "host"=>"localhost"},
  @url="postgres://localhost/foo">
