How to access specific model in rails config/production.rb file?

I want to send exception mail to email_ids stored in yb_notifier_email_ids table. Previously, email_id was hardcoded in production.rb file. I want to send mail by using model. But as configurations file are loaded before active_records I am not able to do this.

-----------migration

        class CreateYbNotifierEmailIds < ActiveRecord::Migration
          def change
            create_table :yb_notifier_email_ids do |t|
              t.string :email_id

              t.timestamps null: false
            end
          end
        end

----------------------------required------------

        config.middleware.use ExceptionNotification::Rack,
            :email => {
              :email_prefix => "[YB] ",
              :sender_address => %{"YB Notifier" <noreply@yb.com>},
              :exception_recipients => YbNotifierEmailIds.pluck(:email_id)
            }
        end

-----------------------I have tried this:

        Rails.application.middleware.use ExceptionNotification::Rack,
              :email => {
                :email_prefix => "[YB-QA] ",
                :sender_address => %{"YB Notifier" <noreply@yb.com>},
                :exception_recipients => defined?(YbNotifierEmailId) && YbNotifierEmailId.table_exists? ? YbNotifierEmailIds.pluck(:email_id) : %w{test@ssolution.com}
        
            }

but defined?(YbNotifierEmailId) && YbNotifierEmailId.table_exists? this condition is getting failed.

This is resolved using lambda. lambda {TableName.pluck(:email_id)}. Thanks
