Class Method Details

.config_with(config, options: {}, whitelist: CONFIG_WHITELIST, defaults: CONN_OPTIONS) ⇒ Object

Generate an options hash suitable for Redis.new’s constructor

The options hash will overwrite any settings in the configuration, and will also accept a special “default_url” parameter to apply when no URL-related parameters are passed in (both in configuration and in options).

The whitelist and defaults keyword parameters control the whitelisted configuration keys to add to the Redis parameters and the default values for unspecified keys. This way you don’t need to rely on hardcoded defaults.
