title: Nested views in a view Rails
body: <p>How can I show the attendances that belong to each event under each event?</p>
  
  <p>Event.rb:</p>
  
  <pre><code>class Event &lt; ActiveRecord::Base
    has_many :attendances, dependent: :destroy
  </code></pre>
  
  <p>Events/index:</p>
  
  <pre><code>%h1 Listing events
  %table
    %thead
      %tr
        %th Starts at
        %th Duration
  
    %tbody
      - @events.each do |event|
        %tr
          %td= event.starts_at
          %td= event.duration
  
  %br
  </code></pre>
  
  <p>I tried this code, but it renders totally all attendances under each event:</p>
  
  <pre><code>%table
    %thead
      %tr
        %th Starts at
        %th Duration
  
    %tbody
      - @events.each do |event|
        %tr
          %td= event.starts_at
          %td= event.duration
          - @attendances.each do |attendance|
            %tr
              %td= attendance.guest
              %td= attendance.attendance_rate
              %td= attendance.event
  %br
  </code></pre>
  
  <p>It looks like I must change something in the array &amp; in controller?</p>
