title: How can I use Simple Form in Rails to only show a specific set of nested attributes?
body: <p>I have an has many association on my <code>School</code> model called <code>PlayerScrape</code>.  I want to use the following code to only show a filtered collection of the association in my form.  How can I do it given the collection <code>@scraped_records</code> being my filtered association records?</p>
  
  <p><strong><em>The following currently shows the 64 records that are associated with that <code>School</code>.</em></strong></p>
  
  <pre><code>&lt;%= form.simple_fields_for :player_scrapes do |field| %&gt;
  </code></pre>
  
  <p>The collection, <code>@scraped_records</code> contains only 13 records of the association that I would like to show in my form.</p>
