  Hi list
 
  I used before with dtml something like this
  dtml-call request.set('sumVar',0)
  dtml-in ...
 dtml-call request.set('sumVar', sumVar + queryVar)
  /dtml-in
  The sum is dtml-var sumVar
 
  This is possible to made with ZPT?

 What about this way:


 dtml-in expr=(1,2,3) prefix=rows
dtml-var expr=rows_itembr
dtml-if expr=rows_end
Total: dtml-var expr=rows_total_item
/dtml-if
 /dtml-in

 José Henrique


How say Andreas and Tres, I made a script

[suma_py]
parameters:
  rec, campo
code:
  suma=0
  for r in rec:
 suma+=r[campo]
  return suma


[index_html]
div tal:define=items aquery()
   div tal:repeat=item items
  ...
  /div
   div
   el importe es span tal:content=suma_py(items, 'importe')
   la cantidad es span tal:content=suma_py(items, 'cantidad')
   /div
/div

 It is possible...

  div tal:define=ignored python:request.set('sumVar', 0)

 but not recommended.  The kind of logic you are trying to wedge into the
 template should be pushed out into a Python script, leaving the template
 only with the job of rendering the results.

Huh? Write a PythonScript (yes, you should know some basic Python)
returning the
data as dict or list or something similar...then render the result as needed
using ZPT. Should be documented in The Zope Book (docs.zope.org).
