Hello again
I´m still testing the usability and reliability of Zope. To accomplish this
goal I am developing a very very simple shopping cart. But I got troubled by
something aparently simple. This is the code:
dtml-in "SESSION['cartItems']"
dtml-in "sqlSearchProduct(productID=sequence-item)"
trtddtml-var productName/tdtddtml-var price/td/tr
/dtml-in
/dtml-in
SESSION['cartItems'] is an array created in another DTML document using the
well known SQLSession product. Here I am retrieving the itens of this array
and passing it to a ZSQL method to get the selected items.
The sqlSearchProduct, alone, works well. If I substitute the inner dtml-in
"sql... for a simple dtml-var sequence-item the block works fine,
otherwise it gives me the following error:
Zope has encountered an error while publishing this resource.
Error Type: NameError
Error Value: sequence
change the line
- dtml-in "sqlSearchProduct(productID=sequence-item)"
to
+ dtml-in "sqlSearchProduct(productID=_['sequence-item'])"
in the line as it is now, sequence-item is interpreted as a Python
expression, meaning sequence minus item. The second incantation gets the
variables 'sequence-item' from the current namespace _
