How to set routes for specific users in rails 7

I am having an issue with Rails_admin. rails_admin is successfully added to the app and working fine.

Issue is when I am trying to set the routes to a specific role user.

My app consists of several role like user, client, admin etc. What I want here is only user with role 'admin' can access to rails_admin section by either using "link_to 'rails_admin_path'" or http://127.0.0.1:3000/admin.

Already I am having an admin section so I don't want to add any other login section for rails_admin, just need the features of rails_admin in my admin.

And I've a method called "check_admin" which will check the role of the current_user is admin or not

current_user.check_admin

#routes.rb

Rails.application.routes.draw do
   mount RailsAdmin::Engine => '/admin', as: 'rails_admin'
end

Here what my requirement is, the given route can be only accessed by admin user

hints: check_admin or current_user.roles.admin.present?

Solution

routes.rb

authenticate :user, -> (u) { u.roles.admin.present? } do
  mount RailsAdmin::Engine => '/admin', as: 'rails_admin'
end

Change route under a condition where it check for the particular role, in my case its "admin".

So the other users who are not an admin can't get an access to rails_admin in anyway
