title: Rails select_tag value Does Not Save in Database
body: <p>I have a form in rails using form_for where users are able to enter in information about an event. One of the options is a dropdown list for ages allowed. A</p>
  
  <p>All of the other information on the form is being sent to the database however this value is never recorded. </p>
  
  <p>The column datatype for :age is integer.</p>
  
  <p>Here is how I'm currently implementing it.</p>
  
  <pre><code>&lt;%= select_tag(:age, options_for_select([['All Ages', 1] , ['18+', 2] ,['21+', 3]])) %&gt;
  </code></pre>
  
  <p>I can provide more information if needed.</p>
