title: How to handle like one two separate date and time fields?
body: <p>How to make two separated fields so can be handled to one <code>datetime field</code> in database?</p>
  
  <p>I'm using jquery datetime picker that puts values like value in code example below. </p>
  
  <p>Parameters includes only field with time but ignores field with date. </p>
  
  <p>If I comment field with time then date is sent and saved but parameter looks like "2013-23-02" and it isn't forwarded like multi parameter.</p>
  
  <pre><code>#model
  field :start_at, type: DateTime
  
  #view
  = f.text_field :start_at, :value =&gt; "2013-02-23"
  = f.text_field :start_at, :value =&gt; "20:20:20"
  </code></pre>
