Question

How can I validate the confirmation of the password? So that the user get an error if the passwords don’t match together. Same as the function “validates_presence_of” gives errors out whether the field is empty.
Sadly doesn’t work this code for me.

<div class="field_left">
  <%= f.label :password, "Password" %><br />
  <%= f.password_field :password %>
</div>
<div class="field">
  <%= f.label :password_confirmation, "Password retry<span>*</span>".html_safe %><br />
  <%= f.password_field :password_confirmation %>
</div>

class User < ActiveRecord::Base
  validates_confirmation_of :password
  attr_accessible :password, :password_confirmation
  attr_accessor :password
end

Can someone help me?

Thank you very much in advance!

The problem was that I implemented the method new so:

@user = User.new (:last_name => params[:user][:last_name], :first_name => params[:user][:first_name] and so on.

Instead of:

@user = User.new(params[:user]

then it works with

validates_confirmation_of :password
attr_accessible :password_confirmation
attr_accessor :password
