title: Rails - select_tag form helper is not working properly
body: <p>I just recently started working in rails forms, and though I have scoured the api docs many times, I have not been able to figure out how to use it properly. </p>
  
  <p>Basically, in my app I have a form to place a manual order (shipping). I would like there to be a select tag for specifying the state to be shipped to. I am working with an pre-existing SQLServer database, and the column I would want to display, and edit is :SHIPTOSTATE . However, when I go to edit an instance of an order, the form always shows "AL" and changing the state does not actually update the shipping state in my form. Can someone point out what I am doing wrong here? </p>
  
  <p>The rest of my form is working beautifully, as the form is mostly text-fields at this point. The text-fields update just fine, but the select_tag is still troublesome.</p>
  
  <p>Here is a snippet of the code in question:</p>
  
  <pre><code> &lt;%= select_tag :SHIPTOSTATE, options_for_select(["AL", "AK", "AZ", "AR", "CA", "CO", "CT", "DE", "FL", "GA", "HI", "ID", "IL", "IN", "IA", "KS", "KY", "LA", "ME", "MD", "MA", "MI", "MN", "MS", "MO", "MT", "NE", "NV", "NH", "NJ", "NM", "NY", "NC", "ND", "OH", "OK", "OR", "PA", "RI", "SC", "SD", "TN", "TX", "UT", "VT", "VA", "WA", "WV", "WI", "WY"]) %&gt;
  </code></pre>
