Dear newsgroup,

I want to iterate over a list returned by a Python script using the <dtml-in> tag of Zope. The script looks like this:

# Script BEGIN missing = []

for curprop in context.sqlGetObjectProperties(objid=curobjid):

found = 0

for prop in context.sqlGetObjectTypeProperties(objtypid=curobjtypid): if (curprop.propid == prop.propid): found = 1

if (found == 0): missing.append(prop.propid)

return missing # Script EOF

The test DTML document looks like this

<dtml-in expr="pyGetMissingObjectProperties(curobjid=objid,curobjtypid=objtypid)"> <dtml-var sequence-index><br> </dtml-in>

and works fine, I see several sequence indexes. But how do I actually access the values from the list? <dtml-var missing> within the <dtml-in> block does not work :(

Of course : "missing" is not a property of each item in the list : it's the list itself, which is returned by the Python script. To get the value of the item, just use <dtml-var sequence-item> (or <dtml-var toto> if each item in the list has a property called "toto"). Thierry
