Module: Ramaze::Helper::Message

Defined in:
lib/zen/helper/message.rb

Overview

The Mesage helper is a Ruby implementation of the Codeigniter library “Message” (located here: https://github.com/isset/codeigniter-message). This helper was taken from another project of mine which can be found here: https://github.com/yorickpeterse/stumpert/

Usage

Basic usage is as following:

message(:error, "Bummer, something went wrong!")

In your layout you’d do the following:

display_messages

This will create and return the HTML for all the messages.
