Implementation of getting user password as part of confirmation for Devise 1.2.x

devise-1-2-x-password-on-confirmation.rb

#This is for Devise 1.2.x

# To your routes file add:

as :user do
    match '/user/confirmation' => 'confirmations#update', :via => :put, :as=> :update_user_confirmation
end

# Add this inherited confirmations controller as app/controllers/confirmations_controller.rb

class ConfirmationsController < Devise::PasswordsController
  skip_before_filter(:authenticate_user!)
  # PUT /resource/confirmation
  def update
    with_unconfirmed_confirmable do
      if @confirmable.has_no_password?
        @confirmable.attempt_set_password(params[:user])
        if @confirmable.valid?
          do_confirm
        else
          do_show
          @confirmable.errors.clear #so that we wont render :new
        end
      else
        self.class.add_error_on(self, :email, :password_allready_set)
      end
    end

    if [email protected]?
      render_with_scope :new
    end
  end

  # GET /resource/confirmation?confirmation_token=abcdef
  def show
    with_unconfirmed_confirmable do
      if @confirmable.has_no_password?
        do_show
      else
        do_confirm
      end
    end
    if [email protected]?
      render_with_scope :new
    end
  end
  
  protected
  def with_unconfirmed_confirmable
    @confirmable = User.find_or_initialize_with_error_by(:confirmation_token, params[:confirmation_token])
    if [email protected]_record?
      @confirmable.only_if_unconfirmed {yield}
    end
  end

  def do_show
    @confirmation_token = params[:confirmation_token]
    @requires_password = true
    self.resource = @confirmable
    render_with_scope :show
  end

  def do_confirm
    @confirmable.confirm!
    set_flash_message :notice, :confirmed
    sign_in_and_redirect(resource_name, @confirmable)
  end
end

show.html.erb

<% @title = 'Account Activation' %>

<%= form_for resource, :as => resource_name, :url => update_user_confirmation_path, :html => {:method => 'put'}, :id => 'activation-form' do |f| %>

      <p><%= f.label :password_confirmation,'Password Confirmation:' %> <%= f.password_field :password_confirmation %></p>
  <% end %>
  <%= hidden_field_tag :confirmation_token,@confirmation_token %>
  <p><%= f.submit "Activate" %></p>

user.rb

# Add these methods to your user model

  # new function to set the password without knowing the current password
  # used in our confirmation controller. 
  def attempt_set_password(params)
    p = {}
    p[:password] = params[:password]
    p[:password_confirmation] = params[:password_confirmation]
    update_attributes(p)
  end

  # new function to return whether a password has been set
  def has_no_password?
    self.encrypted_password.blank?
  end
  
  # new function to provide access to protected method unless_confirmed
  def only_if_unconfirmed
    unless_confirmed {yield}
  end

I'm getting an error: undefined method `only_if_unconfirmed'. I'm using devise 1.2rc

I have the same error with devise 1.2rc
solution :

• replace method "only_if_unconfirmed" by "unless_confirmed"

and another problem is with @confirmable.has_no_password? => replace by "@confirmable.password.blank?"

Sorry guys, I forgot to include the additions to your user model necessary to get this to work. I've added them above.

Ok, I understand why it didn't work :)
Thanks for updated.
