title: Text field value. Display one value send another to the server
body: <p>I have a text field where I want to display a value to the user but send a different value to the server. How can I do this using <code>form_field</code>?</p>
  
  <pre><code>&lt;td&gt;&lt;%= f.text_field :code, value: "Sarah", class: "account-rep-code", readonly: true %&gt;&lt;/td&gt;
  </code></pre>
  
  <p>This will display <code>Sarah</code> and send <code>Sarah</code> to the server on submit. I want to display the value <code>Sarah</code> to the user but send <code>Steve</code> to the server to be saved to the database for <code>code</code>. Is there a way to do this?</p>
