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: csp_reports_controller.rb
    path of file: ./repos/discourse/app/controllers
    
    the code of the file until where you have to start completion: # frozen_string_literal: true
class CspReportsController < ApplicationController
  skip_before_action :check_xhr, :preload_json, :verify_authenticity_token, only: [:create]

  def cre
    
  def create
    raise Discourse::NotFound unless report_collection_enabled?

    report = parse_report

    if report.blank?
      render_json_error("empty CSP report", status: 422)
    else
      Logster.add_to_env(request.env, "CSP Report", report)
      Rails.logger.warn("CSP Violation: '#{report["blocked-uri"]}' \n\n#{report["script-sample"]}")

      head :ok
    end
