Rails Generate Lab

Remember ActiveRecord? It was built for Rails!

home_controller.rb

class HomeController < ApplicationController
  def index

    batman = Superhero.new
    batman.name = 'BATMAN'
    batman.alias = 'Bruce Wayne'
    batman.age = 27
    batman.friends = 'dead'
    batman.powers = 'justice'
    batman.save

    @heroes = Superhero.all

  end
end

ERB also works here!

index.html.erb

<h1>Supereroes aren't hard to find</h1>

<% @heroes.each do |hero| %>
  <li><%= hero.name %> (has an alias of <%= hero.alias %>)</li>
<% end %>

Notice how the names all fit together?

home_controller.rb will automatically have views mapped by methods rendered to /views/controller_name/method_name.html.erb

We don't have to explicitly call erb :view_file to render ERB Views like in Sinatra.
