Allowing user to change password with Devise - Rails 4

Question

I'm setting up the last bit of devise and need to allow a user to change their password from their my account page. I've taken a look at this https://github.com/plataformatec/devise/wiki/How-To:-Allow-users-to-edit-their-password) page from devise and still can't get it to correctly work.

I'm getting the following error when I click on the link to bring up my modal.

ActionController::RoutingError (No route matches [GET] "/users/1/change_password_modal"):

When I submit my change password request I get the following error:

unknown attribute: current_password

My link to bring up the modal is:

button.btn.btn-dashboard data-target="#change_password_modal" data-toggle="modal"

and finally my modal

 <div class="modal fade" id="change_password_modal">
  <div class="modal-dialog">
    <div class="modal-content">
  <div class="modal-header">
    <button class="close" data-dismiss="modal">x</button>
    <h2 class="modal-title">Change Password</h2>
  </div>
    <div class="modal-body">
      <div class="flash"></div>
        <%= form_for(resource, :as => resource_name, :url => edit_user_registration_path, :html => { :method => :put }) do |f| %>
        <%= devise_error_messages! %>
        <div>
          <%= f.password_field :current_password, :autocomplete => "off", class: "sitewide-input", placeholder: "Current Password" %>
        </div>

        <div>
          <%= f.password_field :password, :autocomplete => "off", class: "sitewide-input", placeholder: "New Password" %>
        </div>

        <div>
          <%= f.password_field :password_confirmation, :autocomplete => "off", class: "sitewide-input", placeholder: "New Password Confirmation" %>
        </div>
    </div>
    <div class="modal-footer">
      <p>
        <div>
          <%= f.submit "Update", :class => 'advance-button' %>
        </div>
      </p>
  </div>
<% end %>
</div>
</div>
</div>

I've updated my application controller to include the following:

before_filter :configure_permitted_parameters, if: :devise_controller?

protected

    def configure_permitted_parameters
      devise_parameter_sanitizer.for(:sign_up) << :full_name
      devise_parameter_sanitizer.for(:account_update) { |u| u.permit(:email, :password, :password_confirmation, :current_password)}
    end

Even with this code included I'm getting

ActiveRecord::UnknownAttributeError at /users/edit
unknown attribute: current_password

Answer 1

You need set current_password as permitted parameters on application_controller.rb:

def configure_permitted_parameters
    devise_parameter_sanitizer.for(:account_update) { |u| u.permit(:email, :password, :password_confirmation, :current_password)}
end

And skip the current_password on registration_controller.rb:

class RegistrationsController < Devise::RegistrationsController

  protected

  def update_resource(resource, params)
    resource.update_without_password(params.except(:current_password))
  end
end
