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: plant_countings_controller.rb
    path of file: ./repos/ekylibre/app/controllers/backend
    
    the code of the file until where you have to start completion: module Backend
  class PlantCountingsController < Backend::BaseController
    manage_restfully except: %i[index show]

    list do |t|
      t.action :edit
      t.action :destroy
      t.column 
    
    def show
      return unless @plant_counting = find_and_check

      notify_now :density_is_not_computable_in_counting unless @plant_counting.density_computable?
      respond_to do |format|
        format.html { t3e(@plant_counting.attributes) }
        format.xml  { render xml: @plant_counting }
        format.json
      end
    end
