Module: Bounga::FlashHelper::ViewHelpers

Defined in:
lib/flash_helper.rb

Overview

Global options for helpers

Options for flash helpers are optional and get their default values from the Bounga::FlashHelper::ViewHelpers.flash_options hash. You can write to this hash to override default options on the global level:

Bounga::FlashHelper::ViewHelpers.flash_options[:notice_class] = 'my_notice'

By putting this into “config/initializers/flash_helper.rb” (or simply environment.rb in older versions of Rails) you can easily override any default option.
