Something good has come out of this: while looking for a workaround I
learned about simplejson.dumps(). So now I've defined my own little helper
JD()
import simplejson
def JD(obj):
return XML(simplejson.dumps(obj,indent=4))
In my view (or controller) I can lump into one variable everything I'm going
to need to pass into my js at render time, e.g.
PT = dict(
updatenow=False,
schartoptions = dict(
type ='bar',
barColor ='green',
chartRangeMin = chartmin,
chartRangeMax = chartmax,
)
## add more objects here ...
)
then put a single line at the top of my js script and reference everything
as part of that namespace, e.g.
<script type="text/javascript">
...
var PT = {{=JD(PT)}};
...
$(#something).sparkline( ..., PT.schartoptions);
...
</script>
The JD(PT) expands to a nicely indented js declaration, e.g.
var PT = {
"updatenow": false,
"schartoptions": {
"chartRangeMin": 0,
"barColor": "green",
"type": "bar",
"chartRangeMax": 1
}
};
What's also cool is that if all or part of that declaration corresponds to
data coming in from a getJSON() loop after the page is loaded, then
everything's already defined and initialized.
This feels like a definite improvement over what I was doing before. Far
less clutter and definitely DRY'er.
Cheers,
Mike
