class ActiveRecord::DatabaseConfigurations::HashConfig

Parent:: ActiveRecord::DatabaseConfigurations::DatabaseConfig

A HashConfig object is created for each database configuration entry that is created from a hash.

A hash config:

{ "development" => { "database" => "db_name" } }

Becomes:

#<ActiveRecord::DatabaseConfigurations::HashConfig:0x00007fd1acbded10
  @env_name="development", @spec_name="primary", @config={"database"=>"db_name"}>

Options

:env_name - The Rails environment, i.e. “development”.
:spec_name - The specification 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”.
:config - The config hash. This is the hash that contains the database adapter, name, and other important information for database connections.
