I've read the docs, FAQ, and searched the mailing list. Haven't seen
anything that will answer this question. Maybe it has to do with the fact
that I'm still learning Python (About six to eight weeks along now, part
time).
I have a snippet of HTML like this:
<table py:if="defined('lr.windSpeedAvg')" width="210" cellspacing="0"
cellpadding="0" align="center">
And python code like:
def __getattr__(self, name):
try:
return(self.reading[self.nameToColNum[name]])
except KeyError:
raise Exception("StationReading: The column name %s is invalid"
% name)
Now, you probably already know that the defined() call won't do what I
want it to do. :) For example, if I do a call to hasattr before I call
template.write(), I get:
hasattr(t.lr, 'windSpeedAvg') == True
hasattr(t, 'lr.windSpeedAvg') == False
defined('lr.windSpeedAvg') certainly returns false, even when
lr.windSpeedAvg exists, which is expect, as it's a wrapper for hasattr.
So, how would I check if an attribute exists when it's an attribute of an
object in the templates name space?
Thanks!
