title: How to ignore field from database operation in Laravel Nova
body: <p>I am developing a Web Application using Laravel Nova. Laravel Nova is quite new. I am now having problem with database relationship and Fields. I like to ignore a field from database operations. This is my scenario.</p>
  
  <p>In the Job resource, I have this fields method</p>
  
  <pre><code>public function fields(Request $request)
      {
          return [
              ID::make()-&gt;sortable(),
              Text::make('Name', 'name'),
              Text::make('Email', 'email'),
              Select::make('Contract Types')-&gt;options($array_of_options)//I want to ignore this field
          ];
      }
  </code></pre>
  
  <p>As you can see, the last field is Contract Types. </p>
  
  <p>When I create a new job from Dashboard, it is throwing error because there is no contract_types column on the Job model. I like to ignore that field from database operation. How can I get it?</p>
