After a couple of hours of trial and error, I may have solved this in 2
ways:
1. Using the $current tag like below works.
#for $obs in $Extras.station_observations
"$obs": "#echo getattr($current, $obs) #",
#end for
2. Within an SLE
station_observations = self.generator.skin_dict['Extras'][
'station_observations']
binding = self.generator.config_dict['StdReport'].get('data_binding'
, 'wx_binding')
manager = self.generator.db_binder.get_manager(binding)
currentStamp = manager.lastGoodStamp()
current = weewx.tags.CurrentObj(db_lookup, None, currentStamp, self.
generator.formatter, self.generator.converter)
for obs in self.generator.skin_dict['Extras']['station_observations'
]:
obs_output = getattr(current, obs)
Then add obs_output to the SLE return and use in the tmpl.
Option 2 allows me to be a little more flexible (like adding in DarkSky
visibility API data if obs == "visibility" for example, or a custom rain
and rainRate concat output). Hopefully I'm not re-inventing the wheel too
much here.
