Defined in:
activerecord/lib/active_record/database_configurations/url_config.rb

Overview

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", @name="primary",
  @config={adapter: "postgresql", database: "foo", host: "localhost"},
  @url="postgres://localhost/foo">

Options

  • :env_name - The Rails environment, ie “development”.

  • :name - The db config name. In a standard two-tier database configuration this will default to “primary”. In a multiple database three-tier database configuration this corresponds to the name used in the second tier, for example “primary_readonly”.

  • :url - The database URL.

  • :config - The config hash. This is the hash that contains the database adapter, name, and other important information for database connections.
