title: f.select not defaulting to correct value
body: <p>I have a data model that contains the fields for startMonth and endMonth. I also am able to SET them correctly using the following <code>f.select</code> tags, however, when I go to edit the data, the rendered dropdowns do not reflect the proper values stored in the db. Am i setting the f.select tags incorrectly?</p>
  
  <pre><code>&lt;div class="control-group"&gt;
    &lt;%= f.label "Start Month", :class =&gt; 'control-label' %&gt;
    &lt;div class="controls"&gt;
      &lt;%= f.select :startMonth, options_for_select([['January' ,'1'],['February' ,'2'], ['March', '3'],['April' ,'4'], ['May', '5'],['June' ,'6'],['July' ,'7'], ['August', '8'],['September' ,'9'], ['October', '10'],['November' ,'11'], ['December', '12']]), class: "list-select" %&gt;
    &lt;/div&gt;
      &lt;%= f.label "End Month", :class =&gt; 'control-label' %&gt;
    &lt;div class="controls"&gt;
      &lt;%= f.select :endMonth, options_for_select([['January' ,'1'],['February' ,'2'], ['March', '3'],['April' ,'4'], ['May', '5'],['June' ,'6'],['July' ,'7'], ['August', '8'],['September' ,'9'], ['October', '10'],['November' ,'11'], ['December', '12']]), class: "list-select" %&gt;      
    &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>Once the data is stored using these dropdowns, it stores it correctly in the database and it shows the correct values on my show page. However, I want the dropdowns to default to the stored values when I return to the edit page.  Is there a setting I am forgetting to include?</p>
