Redmine

Because Rails vesion 5.2 upgrade, method "alias_method_chain" don't work.
Would to expert help me to Replace method "alias_method_chain" in Redmine 4.0.2, rails 5.2.

=============================================================================
require_dependency 'account_controller'

module AccountLockable
module AccountControllerPatch # unloadable

extend ActiveSupport::Concern

included do
  # unloadable

alias_method_chain :invalid_credentials, :account_lock
    end

def invalid_credentials_with_account_lock
      invalid_credentials_without_account_lock
      return if params[:username].blank?

user = User.active.find_by_login(params[:username])
      return if user.blank?

login_log = LoginLog.find_or_create_by(user_id: user.id)
      login_log.failed!(request.remote_ip)

if login_log.lockable?
        user.lock!
        login_log.locked!

AccountLockableMailer.account_locked(user, login_log).deliver
      end
    end

end
end

AccountLockable::AccountControllerPatch.tap do |mod|
AccountController.send :include, mod unless AccountController.include?(mod)
end =============================================================================
