You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: loads_controller.rb
    path of file: ./repos/form_core/test/dummy/app/controllers/forms
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

class Forms::LoadsController < Forms::ApplicationController
  skip_before_action :set_form, except: [:show]
  before_action :set_form_with_eager_load_fields
    
  def show; end

  def create
    @instance = @preview.load(serialized_form_data)
    render :create
  end

  private

    def set_preview
      @preview = @form.to_virtual_model
    end

    def serialized_form_data
      params.fetch(:serialized, "")
    end
end
