Custom Flash Class ​

If you want to have a more sophisticated Flash, you can do this by overriding Brut's configuration.

Recipe ​

First, create your new class in app/support/app_flash.rb. You can implement your new methods using [] and []=.

ruby
class AppFlash < Brut::FrontEnd::Flash
  def debug  =   self[:debug]
  def debug? = !!self.debug

  def debug=(debug_message)
    self[:debug] = debug_message
  end
end

Now, in app/src/app.rb's initializer, use Brut.container.override:

ruby
class App < Brut::Framework::App
  def initialize

    # ...

    Brut.container.override("flash_class",AppFlash)
  end
end

Now, any time you inject flash: into a component, it'll be an instance of AppFlash:

ruby
class HomePage < AppPage
  def initialize(flash:)
    @flash = flash
  end

  def page_template
    h1 { "Welcome!" }
    if @flash.debug?
      aside { @flash.debug }
    end
  end
end
