Rails devise without password - ruby-on-rails

Question

I am using devise and i am trying to allow user to modify their information without providing their information. I have followed the tutorial https://github.com/plataformatec/devise/wiki/How-To%3a-Allow-users-to-edit-their-account-without-providing-a-password.
I have this link to allow user to change their own settings
<%= link_to "Account Settings", edit_user_registration_path(current_user) %>
What I did his follow
rails g controller Registration
In the registrations controller replace the content with this
class RegistrationsController < Devise::RegistrationsController
def update
#user = User.find(current_user.id)
email_changed = #user.email != params[:user][:email]
password_changed = !params[:user][:password].empty?
successfully_updated = if email_changed or password_changed
#user.update_with_password(params[:user])
else
#user.update_without_password(params[:user])
end
if successfully_updated
set_flash_message :notice, :updated
# Sign in the user bypassing validation in case his password changed
sign_in #user, :bypass => true
redirect_to after_update_path_for(#user)
else
render "edit"
end
end
end
And in route.rb file i did this
devise_for :users, :controllers => { :registrations => "registrations" }
But it still bring me to the folder /views/devise/registration/edit.erb.html instead of bringing me to /views/registrations/edit.erb.html. I also restarted the server and my computer but no clue what else to do
Update: Note(customers = Users)

Answer 1

You got the name and location of your file wrong.
The file should be called edit.html.erb, not edit.erb.html.
The file should be localed in app/views/registrations.
Also, whenever a url has .id appended at the end, it means that you are passing something to the url helper that you shouldn't be. So in this case, you can remove the current_user argument and use your link like this:
<%= link_to "Account Settings", edit_user_registration_path %>

Answer 2

In config/initializers/devise.rb, uncomment this line config.scoped_views = true then restart Rails server. Also check if your edit.erb.html is in the right directory, it may be need to be in app/views/users/registrations/.
UPDATE:
You need to define edit method in your RegistrationsController because without it will inherit from Devise's RegistrationsController and consequently render Devises's views. Just add these two lines to the controller and it should work.
def edit
end
