SimpleForm submit with cancel link example

gistfile1.rb

module SimpleForm
  class FormBuilder < ActionView::Helpers::FormBuilder
    # You can just override the default submit button and add the functionality.
    #
    # Simple usage: 
    #     f.button :submit 'Send!', :cancel_link => root_path
    #
    def submit(*args)
      cancel_link   = args.last.is_a?(Hash) && args.last.delete(:cancel_link)
      submit_button = super
      submit_button << @template.link_to('cancel', cancel_link) if cancel_link
      submit_button
    end

    # Or you can just create your own helpers to handle that.
    #
    def submit_with_cancel(*args)
      # Do whatever you want here...
    end
  end
