Class Method Details

.install(mailer_class) ⇒ Object

ActionMailer's add_delivery_method unconditionally resets <symbol>_settings to its default_options arg. If the host app has already registered :standard_circuit (e.g. from its own on_load(:action_mailer) block in an env file, queued earlier), calling add_delivery_method again would wipe the settings the app just wrote — causing KeyError: key not found: :circuit at delivery time. Skip if already registered. (This guard assumes the host app registers first; if you call add_delivery_method from after_initialize or otherwise after the gem's Railtie hook fires, use standard_circuit_settings= directly to avoid the reset.)
