judge-simple_form

This is an adapter gem which allows you to use Judge from within your Simple Form forms.

The current version supports Simple Form >= 3. For Simple Form 2 support use 'judge-simple_form', ~> '0.4'.

Do this in your Gemfile:

gem 'judge-simple_form'

Remember to setup Judge in your SimpleForm initializer. Put b.use :judge above b.use :input or b.use :input_label:

config.wrappers do |b|
  b.use :judge
end

Then add :validate => true to the input options in your views. That's all.

<%= simple_form_for(@user) do |f| %>
  <%= f.input :name, :validate => true %>
<% end %>

Judge is a client-side validation gem for Rails.
