Plugin LiveValidation (undefined method)

Andaba probando el plugin live_validations, pero me lanza el
error undefined method `live_validations’ for NilClass:Class

creo que es debido a la linea que hay en lib > form_helpers.rb
alias_method_chain :text_field, :live_validations

aun así tampoco he conseguido que me funcionase :frowning: he seguido el
“little” HOWTO pero no ha habido manera

Modelo

class User < ActiveRecord::Base

validates_presence_of :email
validates_presence_of :password
validates_presence_of :password_confirmation
validates_format_of :email, :with =>
/^([^@\s]+)@((?:[-a-z0-9]+.)+[a-z]{2,})$/i

end

Vista

<% form_for :user, :url => users_path do |f| %>
email <%= f.text_field :email %>


password <%= f.password_field :password %>


password_confirmation <%= f.password_field :password_confirmation %>
<% end %>

completo, etc.)? No he conseguido reproducir el error…

hola, lo había probado con la versión pre-2, y al no funcionar lo probé
con la versión 1.2.3 obteniendo en ambas versiones el mismo error.
te pongo el resultado que aparece en el development.log

voy a seguir probando a ver si consigo hacerlo funcionar.

Gracias
