User can't delete his own account , Rails 4 + Devise - ruby-on-rails

Question

I have Ruby on Rails 4 application also I am using Devise gem to provide login/register.
Everything works just fine, but users that are logged in can't delete their own account. Any other delete functions work, so Javascript shouldn't be a problem.
In view:
<%= link_to "Delete account", registration_path(resource_name), data: { confirm: "Your profile will be permanently deleted. Are you sure?" }, method: :delete%>
I am overriding default devise Registration controller with this:
class RegistrationsController < Devise::RegistrationsController
clear_respond_to
respond_to :json
protected
def update_resource(resource, params)
resource.update_without_password(params)
end
end
My log file:
Started DELETE "/ru/users" for xx.xxx.xxxx.xx at 2015-05-26 22:30:45 +0300

Description:
When user pushes delete button, user gets message :
translation missing: ru.devise.registrations.user.destroyed
also he is logged out from his account, but the actual destroying never happens. What could be possible problem?
Thanks for your time.
Best wishes.

Answer 1

Here Destroy deletes user account by using destroy method of devise registrations_controller. For translation missing: ru.devise.registrations.user.destroyed you need to make changes in devise.ru.yml file -
ru:
devise:
registrations:
user:
destroyed: 'Bye! Your account was successfully cancelled. We hope to see you again soon.'
This is background process. So, you can't see in your logs(delete sql query).
