ActiveAdmin Gem: Redirect user to login page if not logged in

Question

I am working with active admin gem and it is working great. But a minor that I'm facing is whenever I manually enter a url such as:

https://www.example.com/admin/users/5 

and if the admin is not logged in then the above url page shows:

{"errors":["You need to sign in or sign up before continuing."]}

which is fine, but I want a redirection to the login page and if admin log in from the page, it should show up the desired page pointing to https://www.example.com/admin/users/5

I'm not able to figure out the redirection procedure for ActiveAdmin.

Answer 1

In config/initializers/active_admin.rb you have such config

config.authentication_method = :authenticate_admin_user!

then create a method named authenticate_admin_user! in the ApplicationController

def authenticate_admin_user!
  #check for current_user if not then redirect to login
end
