ruby on rails password_confirmation validation

Question

i've a problem with password confirmation validation

in User Model:

 validates :password, :confirmation => true

and in the view new.html.erb:

 <%= form_for(@user) do |f| %>
   <div class="field">
     <%= f.label :password %><br />
     <%= f.password_field :password %><br />
     <%= f.label :password_confirmation %><br />
     <%= f.password_field :password_confirmation %><br />
   </div>
   <div class="actions">
     <%= f.submit %>
   </div>
 <% end %>

so for any inserted data the validation throw error. i think that there's something wrong with :password_confirmation and RoR received it with nil value is it possibile? how can i do?

Impossible to help you based on what you've posted. We would have to see how you're attempting to assign parameters to your model. Also, you shouldn't be doing this anyways. Use has_secure_password in Rails 3+. — user229044

it isn't an error... when i inserted the password and the password_confirmation form field and click on 'submit' remain in the same page and there the message error, impossible to save: password and his confirm are different. — Dabidi

try this

class User < ActiveRecord::Base
  validates :password, :presence =>true, :confirmation =>true
  validates_confirmation_of :password
end

The Controller is intended take the data from the view and try to perform save, this is the code of the view:

<%= form_for(@user) do |f|%>
  <% if @user.errors.any? %>
    ....
    ....
  <% end %>
  <%= f.label :email %><br />
  <%= f.text_field :email %><br />
  <%= f.label :password %><br />
  <%= f.password_field :password %><br />
  <%= f.label :password_confirmation %><br />
  <%= f.password_field :password_confirmation %>
  <%= f.submit %>
<% end %>


NOTE: This check is performed only if password_confirmation is not nil, and by default    only on save. 
To require confirmation, make sure to add a presence check for the confirmation attribute:
