How to: override devise default routes of sign in and sign out
MyApp::Application.routes.draw do
# If you concern about SEO then send permanent redirect (301) on old routes to new routes
# It is always better to do this setting in web server that is in nginx or apache.
# Here I am showing how to do it in rails routes file
get '/users/sign_in', to: redirect("/sign-in")
get '/users/sign_up', to: redirect("/sign-up")
# Need to skip session and registration so that we can override them in devise_scope block
# If we not do so then default route of devise continue to work
devise_for :users, :skip => [:sessions, :registrations]
