title: How to set a property once it has been saved and re-save a child property?
body: <pre><code>factory :user do
    company
    phone "123-123-1234"
    .
    .
  
  end
  </code></pre>
  
  <p>The company model has a property that I need to set also:</p>
  
  <pre><code>company.owner_id = -1
  </code></pre>
  
  <p>But I need to set the owner_id to the user's id.</p>
  
  <p>How can I do this?</p>
