I'm in the middle of trying to reimplement some DTML stuff in ZPT and I'm hitting what must be newbie problems. 1) Iteration and python expressions. I've got something like this: <table class="info" width="100%"   tal:repeat="origin python:here.getorigins( fd=request.other['from_date'], td=request.other['to_date'])"> I then want to nest another repeat statement, based on origin: <tr class="somerow" tal:repeat="row python:here.innerstuff(  request.other['from_date'],  request.other['to_date'], origin)"> <!-- this line is borked --> Using 'origin' here fails, as does 'repeat.origin' or 'repeat.origin.origin' (the actual attribute I'm trying to get to) or 'repeat['origin'].origin'. What is the chant I need to access repeat variables from python expressions? 2) Whither 'fmt='? I know this was answered but my search hasn't turned up any answer. I used to do this: <td class="num"><dtml-var hits fmt="%d"></td> <td class="num"><dtml-var ratio fmt="%.1f">%</td> This works in ZPT: <td class="num" tal:content="python:'%d' % int(row.hits)">0.0</td> <td class="num" tal:content="python:('%.1f' % float(row.ratio))+'%'">0.0%</td> But it seems like there should be an easier way.
