This is an old question - but I recently had solve the same issue and came up with a solution which is far more elegant than:

devise_for :users, :skip => [:registrations] 
as :user do
  get 'users/edit' => 'devise/registrations#edit', :as => 'edit_user_registration'
  put 'users' => 'devise/registrations#update', :as => 'user_registration'
end

And it gives the default names for the named routes (like cancel_user_registration) without being excessively verbose.

devise_for :users, skip: [:registrations]

# Recreates the Devise registrations routes
# They act on a singular user (the signed in user)
# Add the actions you want in 'only:'
resource :users,
    only: [:edit, :update, :destroy],
    controller: 'devise/registrations',
    as: :user_registration do
  get 'cancel'
end

rake routes output with the default devise modules:
