Baywatch

Installation

Add this line to your application's Gemfile:

gem 'baywatch'

And then execute:

$ bundle

Usage

Declarative way to error handling inside controller

  class UsersController < ApplicationController
    include Baywatch::Rescue

    # By default will handle([ Errno::ECONNREFUSED, Errno::ECONNRESET ])
    service_down do |on|      
      on.index do
        flash[:error] = "Sorry, the service is not working properly"
      end
      on.create do 
        flash[:error] = "Sorry, we cannot save right now"
        flash.keep(:error)
        redirect root_url
      end
    end

    def index
      @users = UserRemoteService.all
    end

    def create
      UserRemoteService.create(params[:user])
    end

  end

Using #only to use the same behavior to many actions.

  class UserController < ApplicationController
    include Baywatch::Rescue

    service_down do |on|      
      on.only :index, :create do
        flash[:error] = "Sorry, the service is not working properly"
        redirect_to root_url
      end
    end

    def index
      @users = UserRemoteService.all
    end

    def create
      UserRemoteService.create(params[:user])
    end

  end

TODO

Handle Contextual Exception

  service_down do |on|

    on.edit(ActiveRecord::RecordNotFound)
      flash[:error] = "Not Found"
      redirect_to root_url
    end

    on.edit(Base::WhateverException)
      flash[:error] = "Whatever Message Here"
      MailAdministrator.send(:fail")
      redirect_to root_url
    end
  end
