    Metadata details:
    filename: direct_uploads_controller.rb
    path of file: ./repos/consuldemocracy/app/controllers
    
    the code of the file until where you have to start completion: class DirectUploadsController < ApplicationController
  include DirectUploadsHelper
  include ActionView::Helpers::UrlHelper
  before_action :aut
    
  def create
    @direct_upload = DirectUpload.new(
      direct_upload_params.merge(user: current_user, attachment: params[:attachment])
    )

    if @direct_upload.valid?
      @direct_upload.save_attachment
      @direct_upload.relation.set_cached_attachment_from_attachment

      render json: { cached_attachment: @direct_upload.relation.cached_attachment,
                     filename: @direct_upload.relation.attachment_file_name,
                     destroy_link: render_destroy_upload_link(@direct_upload),
                     attachment_url: polymorphic_path(@direct_upload.relation.attachment) }
    else
      render json: { errors: @direct_upload.errors[:attachment].join(", ") },
             status: :unprocessable_entity
    end
