    end 

    def create 
    @product_import = ProductImport.new(params[:product_import]) 
    if @product_import.save 
     redirect_to root_url, notice: "Imported products successfully."

require 'csv'  
class ProductImportsController < ApplicationController 
    def new 
    @product_import = ProductImport.new 
    end 

    def create 
    csv_text = File.read(params[:product_import]) 
    csv = CSV.parse(csv_text, :headers => true) 
    csv.each do |row| 
     ProductImport.create!(row.to_hash) 
    end 
    end 
end
