Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(*args, &block) ⇒ Object

Internal: Send any unknown methods to the template.

This is done so you don’t have to access them through h.

Examples

class XxxPresenter < BasePresenter
  ...
  def my_attribute
    content_tag :span, "Duck", :class => "mallard"
  end
  ...
end

end
