title: Using Rails validation helpers :message but want it without listing the column name in message
body: <p>Using Rails validation helpers-</p>
  
  <pre><code>validates_xxx_of :the_column, :message =&gt; "my message"
  </code></pre>
  
  <p>will generate a validation message :</p>
  
  <p><em>the_column my message</em></p>
  
  <p>Is there a way to turn-off the inclusion of the column name?
  (substitute xxx with any validation helper method)</p>
