throughcheckboxes

h2. Introduction

This gem will help you to handle has_many :through associations when you need to add/remove these ones with checkboxes. If you think about this type of situation you do the same steps for each association you have to handle with checkboxes. I exctracted this gem from a project where I had to handle about ten associations with checkboxes.

h2. How to use it

The best way to describe throughcheckboxes is to show some code:

In your model:

class User < ActiveRecord::Base

  # adds your associations
  checkboxes_for :groups
end

In your view:

<%= form_for @user do |f| %>
  <%= f.error_messages %>
  <%= f.checkboxes_for :groups  %>
  

  
<%= f.submit %>
<% end %>

and that's all. Now, when you submit your form you get the has_many :through association updated.

h2. Roadmap

• write tests
• write options for helper
• write more helpers
