Google APi ruby client

I have a method to create folder on Google drive as soon a create method is hit. I want the folder to created once the batch is saved. Below is the code Im using. In the below method page redirects as soon as it is authorised. So requesting for workarround

 def create
    client = Signet::OAuth2::Client.new(
      :authorization_uri => 'http://ift.tt/IlrJzQ',
      :token_credential_uri =>  'http://ift.tt/1yJFQ0y',
      :client_id => "XXXXXX-XXXXXX",
      :client_secret => "XXXXXX-XXX",
      :scope => 'http://ift.tt/JALASw',
      :redirect_uri => "http://localhost:3000/batches/"
      )
    @batch = Batch.new(params[:batch])

    respond_to do |format|
      if @batch.save

        if params[:code].present?
          client.code = request['code']
          client.fetch_access_token!
          x = Google::Apis::DriveV3::DriveService.new
          x.authorization = client
          files = x.list_files(options: { authorization: client })
          file_metadata = {
            name: 'Batches-new',
            mime_type: 'application/vnd.google-apps.folder',
          }
        file = x.create_file(file_metadata, fields: 'id')
            Rails.logger.debug "Folder Id: #{file.id}"
        else
          format.html {redirect_to client.authorization_uri.to_s}
        end

        format.html {redirect_to batches_path(trek_id: @batch.trek_id), notice: 'Batch was successfully created.' }
        format.json { render json: @batch, status: :created, location: @batch }
      else
        format.html {
          flash.now[:error] = @batch.errors.full_messages
          render action: "new"
        }
        format.json { render json: @batch.errors, status: :unprocessable_entity }
      end
    end
  end

after hiting the create action page navigates to index page without creating folder. How to make folder gets created before going to index page. Thanx in advance.
