I'm using rails 6 and devise for authentication. I know it can be done with session but dont know how. I will be thankful for your kind response.
If by active you mean that a user hasn't signed in for x months. Then you can check last_sign_in_at
column in users
table. The column should be created by Devise.
months = 6 # Put your value here
if user.last_sign_in_at? && user.current_sign_in_at.blank?
user.last_sign_in_at < Time.now.months_ago(months)
end
If a user has never been signed in you can check created_at
field in a similar way.
