How to disable access without emailing user

Support

Here’s some code that will do it at the rails console:

./launcher enter app 
rails c

username = "user-to-suspend-username"
admin_username = "admin-username"
reason = "suspend reason"
till = Time.at(33174889200)
u = User.find_by_username(username)
puts "couldn't find user named #{username}" unless u
if u and !u.suspended?
  u.suspended_till = till
  u.suspended_at = DateTime.now

  User.transaction do
    u.save!
    admin = User.find_by_username(admin_username)
    StaffActionLogger.new(admin).log_user_suspend(
      u,
      reason
    )
  end
  u.logged_out
end
