# Alert Message

[![Gem Version](https://badge.fury.io/rb/alert_message.svg)](http://badge.fury.io/rb/alert_message)

This is a simple gem for [alerts messages](http://rubygems.org/gems/alert_message).

## Installation

Add to your Gemfile:

    gem 'alert_message'

Then run:

    $ bundle install

Run install script:

    $ rails g alert_message:install

Add styles in app/assets/application.css

    *= require alert_message

Add scripts in app/assets/application.js

    //= require alert_message


## How to use

Add in app/views/layouts/application.html.erb

    <%= render "layouts/alerts" %>

To show your alerts, use:

    flash[:error] = "YOUR MESSAGE"
    flash[:notice] = "YOUR MESSAGE"
    flash[:success] = "YOUR MESSAGE"

#### Example

    class HomeController < ApplicationController
      def index
          flash[:error] = "YOUR MESSAGE"  
      end
    end

## Custom message to Devise

Some devise screens do not accept Flash Messages. For this we will use a custom helper.

Add in your app/views/layouts/_alerts.html.erb

    <%= show_messages %>

Create helper alert_message_helper.rb

    module AlertMessageHelper
      def show_messages
        return "" if resource.errors.empty?
        messages = resource.errors.full_messages
        html = <<-HTML
          <div class="alert alert-danger">
            #{messages.first}
          </div>
        HTML
        html.html_safe
      end
    end
