Devise redirect back to the original location after sign in or sign up?

Question

Here I\'m using Devise Gem for authentication. If someone want to open page without login then it redirect to sign_in page and after signed in it back to the page which user

Answer 1

gem 'devise', '~> 4.4.0'

1. Create sessions_controller.rb: class SessionsController < Devise::SessionsController

2. Add the following (modifying the regex if your login url isn't /users)

   def before_login
     session[:previous_url] = request.fullpath unless request.fullpath =~ /\/users/
   end
   
   def after_login
     session[:previous_url] || root_path
   end
   

Notice that this does not work if you've got /users/dashboard or other locations under /users. Might want to get more specific with the regex.
