      Description

      Hi there! We just upgraded from mongodb 2.6.6 and mongoid 4.x to mongodb 3.4.3 and mongoid 5.2. We are using the ruby 2.4.2 mongo driver. We have some code to copy collections from one server to another. We used to use the Moped classes to do this, but the rename method is not available on the Mongo::Collection object. I have listed the OLD Code snippet below AND the* NEW Code* snippet. Looking for some direction on rewriting the items in red below in the NEW Code snippet using the mongo driver. Thanks! -Steve

      OLD Code:
      def copy_footnotes_from_prod
      session_to = Moped::Session.connect(Settings.footnotes_copy["#

      {params[:target_env]}

      _mongo_uri"])
      prod_master = nil
      prod_session = Moped::Session.connect(Settings.footnotes_copy.prod_mongo_uri)
      response = prod_session.command(ismaster: 1)
      prod_master = response[:primary] if response[:primary].present?
      prod_session.disconnect
      if prod_master
      session_to[:footnotes_backup].drop
      session_to[:footnotes].rename("footnotes_backup")
      return_hash1 = session_to.command(

      {cloneCollection: "fund.footnotes", from: prod_master}

      )
      session_to[:footnotes_backup].drop
      session_to.disconnect
      Rails.logger.info "1> #

      {return_hash1}"
      message = "Successfully copied footnotes From Prod to DEV"]}"
      else
      message = "No Master Found"
      end
      redirect_to admin_path, notice: message
      * end*

      *NEW CODE:

      def copy_footnotes_from_prod*
      session_to = Mongo::Client.new(Settings.footnotes_copy["dev_mongo_uri"],
      :connect => :replica_set, :read => { :mode => :primary},
      :auth_mech => :scram,
      :auth_source => :admin,
      :user => "ourID",
      :password => "DONOTSHOW")

      prod_session = Mongo::Client.new(Settings.footnotes_copy["prod_mongo_uri"],
      :connect => :replica_set, :read => { :mode => :primary},
      :auth_mech => :scram,
      :auth_source => :admin,
      :user => "ourID",
      :password => "DONOTSHOW")

      if prod_session
      ft = session_to[:footnotes_backup]
      ft.drop
      cc = session_to[:footnotes]
      cc.renameCollection("footnotes_backup")
      return_hash1 = session_to.command({cloneCollection: "fund.footnotes", from: prod_session})
      dd = session_to[:footnotes_backup]
      dd.drop
      session_to.disconnect
      prod_session.disconnect
      Rails.logger.info "1> #{return_hash1}

      "
      message = "Successfully copied footnotes From Prod to DEV"]}"
      else
      message = "No Master Found"
      end
      redirect_to admin_path, notice: message

      • end*
