This is a tough problem. I think we're hitting the limits of the Cheetah
parser!
Here's the problem. The expression that sets archive_data gets evaluated
*immediately*, resulting in tuples that consist of a string, and a
TimeSpanBinder object.
#set $archive_data = [('day', $day), ('week', $week), ('month', $month),
('year', $year), ('rainyear', $rainyear)]
So, later, it interprets an expression like
$archive[1](data_binding='wx_binding')...
as being a call to a TimeSpanBinder, rather than a call to a constructor.
The only way I can think of to get around this is to refactor the
archive_data expression so it reads
#set $archive_data = [('day', $day, $day(data_binding='sdr_binding')),
('week', $week, $week(data_binding='sdr_binding')), ('month', $month,
$month(data_binding='sdr_binding')), ('year', $year,
$year(data_binding='sdr_binding')), ('rainyear', $rainyear,
$rainyear(data_binding='sdr_binding'))]
Each tuple now consists of (a string, a plain TimeSpanBinder, and a
TimeSpanBinder bound to the sdr_binding data binding) --- what you
want.
Now your block looks like
<tr>
<td class="label">$obs.label.extraTemp6</td>
#for $archive in $archive_data
<td class="data new_row hilo_$archive[0]">
<span title="$archive[2].extraTemp6.maxtime">
$archive[2].extraTemp6.max.format(add_label=False)</span><br/>
<span title="$archive[2].extraTemp6.mintime">
$archive[2].extraTemp6.min.format(add_label=False)</span>
</td>
#end for
<td class="units">$unit.label.extraTemp6</td>
</tr>
Hope this helps.
