How to “soft delete” user with Devise (3)

A complete tutorial can be found at Soft Delete a Devise User Account on the Devise wiki page.

1. Add a "deleted_at" DATETIME column
2. Override users/registrations#destroy in your routes
3. Override users/registrations#destroy in the registrations controller
4. Update user model with a soft_delete & check if user is active on authentication
5. Add a custom delete message

I currently use Devise for user registration/authentication in a Rails project. When a user wants to cancel their account, the user object is destroyed, which leaves my application in an undesired state.

What is the easiest way to implement a "soft delete", i.e. only removing personal data and marking the user as deleted? I still want to keep all record associations.

I assume I will have to first introduce a new "deleted" column for users. But then I am stuck with this default code in the user's profile view:

<p>Unhappy? <%= link_to "Cancel my account", registration_path(resource_name), :confirm => "Are you sure?", :method => :delete %>.</p>

Where can I find the :delete method? How should I overwrite the default Devise methods?

Adding onto hakunin's answer:

To prevent "soft deleted" users from signing in, override active_for_authentication? on your User model:

def active_for_authentication?
  super && !deleted_at

You could use acts_as_paranoid for your User model, which sets a deleted_at instead of deleting the object.
