title: Add field text from relationship in laravel nova in ONE form
body: <p>I'm new on Laravel Nova.
  I'm trying to build a User form.
  In this moment I have these models:
  <strong>User, UserDetail</strong></p>
  
  <p>In User I have: email, password, username.
  In UserDetail I have: Name, Lastname, Gender, Number, etc.</p>
  
  <p>Now I would create <strong>One</strong> form for user.
  Why I'm focusing on <strong>ONE</strong>?
  Because in my User Resource fields I have:</p>
  
  <pre><code>HasOne::make("UserDetail", "details"),
  </code></pre>
  
  <p>But For set user detail I have 2 form:
  One for User data (username, password, email) And after save the user I can set detail.</p>
  
  <p>So I don't want compile 2 different form for 1 resource.</p>
  
  <p>I have found this package, but seems broke:</p>

  <p>And the fields UserDetails doens't shown.</p>
  
  <p>So is there any other way for add text field from relationship and merge in same Form?</p>
