Issue with NOAA Template when trying to add additional fields

[Rahul Bedi]

Hi,

I have been trying to update the NOAA template to incorporate the air quality data in the monthly report, but when I added the two entries (in red)  in the file  NOAA-YYYY-MM.txt.tmpl, I an error (attached at the end).

Interestingly the same two entries, in the hilo.inc file in the Seasons skin work fine.

Even more interestingly, the same two entries placed just before the "MONTHLY ..." line, work just fine.

Any idea about what am I doing wrong ?

Thanks.

Hi,

Try using:

$day($data_binding='purpleair_binding').pm2_5_atm.maxtime.format($Time) $day($data_binding='purpleair_binding').pm2_5_atm.max.nolabel($Count,$NONE)

Gary

[Rahul Bedi]

Tried. I get a similar error:

I think I see what is going on. Normally you can pass a $data_binding to a $day tag to pull an aggregate from another database. However, in this case the $day tag is not a normal $day tag but rather it comes from iterating over all of the days in the month (for $day in $month.days) and you can't pass a $data_binding to that $day (I suspect you can pass it to $month but that is going to apply the same data binding to all $day tags). So I can't see how it can be done (short of putting you air quality data in the same database). Might be worth waiting till Tom looks at this, he may have some cunning magic he can perform.

Yes, this is a limitation in the iterators: they cannot use a data binding. There's probably a workaround, but I'd have to think about it a bit.

In the meantime, I've put up issue #580 to track.

Probably related to issue #384 as well.

Thanks Tom and Gary. The only other way I can think of is to do the kludgy way of removing the loop altogether and doing it 31 times for the month :(. Not pretty but had to do that in hilo.inc

BTW if I was to manually replace $day with a variable that is, say, the first day of the month ? How would I do that ?

I am trying to remove the loop and replace that with 31 lines that will be one for each possible date.

Thx.

There is nothing that will directly give you the first of the month. The closest you can do is $days_ago:

$day($data_binding=‘some binding’, $days_ago=20).outTemp.maxtime

But of course as we move through the month the actual day provided will change. You could use a little in-line python in your template to calculate an offset based on the current day of month to use with the number of days ago and then use that in the tag, eg (untested):

#set $offset = (some calculation)
$day($data_binding=‘some binding’, $days_ago=$offset).outTemp.maxtime
$day($data_binding=‘some binding’, $days_ago=$offset+1).outTemp.maxtime

Not sure how well that will work (not sure if in-line calculation is supported in $day() tags) and it’s starting to get complex and messy.

For info detail on aggregate tag usage can be found in the Customization Guide (http://weewx.com/docs/customizing.htm#general_aggregation_periods).

Turned out allowing iterators to use data bindings was an easier problem than I thought. Fixed in commit b50fe45

Now you can do something like 

#for $day in $month.days
$day($data_binding='purpleair_binding').pm2_5_atm.max
#end for
