Question

I’m fairly new to Ruby on Rails and I’m having what seems like an easy problem but I can’t seem to figure out what I have done wrong. My homepage has a button and when you click the button, its supposed to create an xml file with information from the database.

Button code:

<%= button_to "Create Google File", :action => :create_google_file %>

Controller code:

class ProductsController < ApplicationController
  def new
  end

  def create_google_file    
      @products = Product.find(:all)
      file = File.new('dir.xml','w')
      doc = @products.to_xml

      file.puts doc
      file.close
  end
end

The error I’m getting is

No route matches {:action=>"create_google_file", :controller=>"products"}

Answer 1

Add this to your config/routes.rb file

match "/create_google_file" => "products#create_google_file", :as => :create_google_file

And change the button to this

<%= button_to "Create Google File", create_google_file_path %>
