Using Parsley With Rails - ruby-on-rails-3

Question

I am trying to add parsley.js to a rails project to do client side form validation and can't seem to get it working.
I am using the gem for parsley for the rails asset pipline - https://github.com/mekishizufu/parsley-rails
gem "parsley-rails"
I went ahead and required it in my application.js file
//= require jquery
//= require parsley
//= require jquery_ujs
//= require twitter/bootstrap
//= require_tree .
And then I added the following to the form I wish to validate on
<%= form_for :user, :html => {:"data-validate" => 'parsley'} do |user| %>
Which generates a data attribute in the html for the form
data-validate="parsley"
Then to check for the presence of the address I have:
<%= label_tag :current_address %>
<%= text_field_tag :address, nil, :data => {:"required" => 'true'} %>
Which renders a text field with a attribute for the text field
data-required="true"
Yet when I click submit no validation occurs and a post request is made. What else do I need to do in order to get parsley working on a rails 3 form? Much appreciated!

Answer 1

The gem uses Parsley-js version 1.2.3, as 2.0.0 is still a release candidate. Here are the docs for that version: http://parsleyjs.github.io/Parsley-1.x/documentation.html
The attributes are a bit different - the form_for tag should look like this:
<%= form_for :user, :html => {'parsley-validate' => ''} do |user| %>
and the text field:
<%= text_field_tag :address, 'parsley-required' => '' %>
Hope this helps.
Update
The 'parsley-rails' gem is now using v2.0.

The current version is now 2.0.5 and the docs can be found here http://parsleyjs.org
Using the rails gem you need to now add data-parsley-validate to the form and directives like required to the inputs.
Inside a rails form I had luck with:
<%= form_for #post, :html => {"data-parsley-validate" => true} do |f| %>
<%= f.text_field :title, :placeholder => "Title", :required => true %>
Hope this helps someone until parsley-rails gets some better links or basic usage docs in the readme. Might be a nice PR...

Answer 3

I got parsley to work in our Rails application by initializing parsley with
$('#form-id').parsley({ 'data-parsley-focus': 'first' });
the 'data-parsley-focus' is an option for where parsley will send the cursor if validations fail.
I included the gem as you did in gemfile, but my application.js loads parsley after the ujs adapter
//= require jquery
//= require jquery_ujs
//= require parsley
