 # if we want to effectively leverage SEO on our website, we'll want to provide custom title, description, and keywords on some of the pages... one way we can do this is:

 # <!DOCTYPE html>
 # <html>
 # <head>
 #   <title>Big Store <%= @title %></title>
 #   <meta name="description" content="<%= @description || "Selling the best chaps ..." %>">
 #   <meta name ="keywords" content="<%= @keywords || "chaps, cowboy shop, leather" %>">

 class ProductsController < ApplicationController
  def index
    @product = Product.find(params[:id])
    @title = @product.name
    @description = @product.description
    @keywords = @product.tags.join(",")
  end
 end

 # However, it kinda feels a little sloppy to put view concerns inside your controller
 # Here's an alternative

 # <!DOCTYPE html>
 # <html>
 # <head>
 #   <title>Big Store <%= yield(:title) %></title>
 #   <meta name="description" content="<%= yield(:description) || "Selling the best chaps ..." %>">
 #   <meta name ="keywords" content="<%= yield(:keywords) || "chaps, cowboy shop, leather" %>">

 # Now if we want to set title, description, or keywords, we can do so from anywhere in our views

 # <% 
 # content_for(:title) { @product.name }
 # content_for(:description) { @product.description }
 # content_for(:keywords) { @product.tags.join(",") }
 # %>

 # it might be worthwhile to extract these into helpers... In our helper:

 def title(title)
  content_for(:title) { title }
 end

 def description(description)
  content_for(:description) { description }
 end

 def keywords(input)
  content_for(:keywords) { input }
