ruby on rails - Override PasswordsController in Devise to change password when the user is already signed in -

i want add feature app in when user signed in can change password clicking on change password link.but when click on link redirects current page.

<%= link_to 'change password', edit_user_password_path %> 

can tell me solve problem?

because can't write comment (my reputation low) i'll write answer instead.

take here:

rails devise edit_user_password_path

this should solve problem.

in short: devise passwordscontroller can used if user signed_out.
