Sisyphus::Rails

A gem to add gmail like form saving through sisyphus.js

Installation

Add this line to your application's Gemfile:

gem 'sisyphus-rails'

And then execute:

$ bundle

Or install it yourself as:

$ gem install sisyphus-rails

For a basic install include the following in your app/assets/javascripts/application.js file

//= require sisyphus

To support IE6/7 users include jStorage as well

//= require jstorage
//= require sisyphus

How it Works

Sisyphus uses an aliased form_tag method to automatically put a <script>...</script> tag infront of your forms to initialize Sisyphus. It also uses an aliased FormHelper form_for method to read options.

<script>$(document).ready(function() {$('#sampleform').sisyphus();});</script>
<form id="sampleform">
  ...
</form>

Usage

Sisyphus automatically works with all your forms, including custom form builders.

Exclude form

To stop Sisyphus from initializing on a form include the with_sisyphus option in your form_for.

<%= form_for User.new, :with_sisyphus=>false do |f| %>
  ...
<% end %>

Dependencies

• Rails >= 3.1
• Jquery 1.8+

TODO

• Tests

• Move away from form_tag_helper, should be able to do it all from form_helper? Script tag can go at the end anyhow. Why aren't we doing that right now? We don't seem to have access to the same variables that the regular form_for does. Also the options array gets muddied by the FormHelper form_for call -> it removes the [:html] section (we need the id of the form for sisyphus).

• conflict resolution... i.e. you have an object edit form, the fields are populated from the DB but if you have local browser changes they may get overridden. We need a way to resolve conflicts between local and remote data -> could use a jquery based modal dialog to present the diff?

• Model based exclusions via activerecord extension?

• block based options (this would allow us to easily and neatly implement Sisyphus options)

  <%= form_for User.new do |f| %> <% :sisyphus => flase %> <% :sisyphus_customKeyPrefix => 'sisy' %> ... <% end %>

• implement all sisyphus options and any relevant ones in jStorage
