How do you sort by earliest date?
I tried .sort and I get
<td><%= effort.week_commencing.sort %></td>
// => undefined method `sort' for Mon, 12 Sep 2011:Date
The values are not in an array they are listed in a table.
You can use the
sortmethod only on array’s.I don’t think
effort.week_commencingis returning an array in your case.check what are you getting in effort.week_commencing.
