[Zope] dtml-calendar efficiency?

[Michael Ciavarella]

Hi all,

I've been bouncing around the idea of adding an optional tag parameter
'batchMethod' to the <dtml-calendar> tag.  This parameter would specify
a method that could be used to pre-fetch data in the date range being
rendered.

Rather than reinventing the wheel, is there another (ie already exists)
way to efficiently back the <dtml-calendar> tag with a ZSQL method?
With the standard "usage", the tag issues one call to the method (i.e. one
query) for each date on the presented calendar.

Thanks in advance
