title: How do I get the label string value from a :select box in formtastic
body: <p>I have the following in a partial in a Rails 3.2 app using formtastic gem</p>
  
  <pre><code>&lt;%= f.semantic_fields_for :bucket do |bucket| %&gt;
                         &lt;%= bucket.inputs do %&gt;
                                 &lt;%= bucket.input :bucket_name, :collection =&gt; @buckets,
                                 :include_blank =&gt; false %&gt;
                                 &lt;%= bucket.input :sub_directory, :collection =&gt;
  @buckets.first.paths,
                                 :include_blank =&gt; false %&gt;
                         &lt;% end %&gt;
                 &lt;% end %&gt;
  </code></pre>
  
  <p>right now in my controller I can get  :bucket_name and the value is ==
  to an integer, In my case I only have one item in my collection but it is giving me a value of 2. My guess is this is the ID value of the object.</p>
  
  <p>it's important that I get the actual :name string value of the object
  that is selected in the collection. I am not sure how to do this. so
  let's say the item I select has a label of "my label" and it's the 3rd
  item in the collection. how would I grab the value "my label".</p>
