Oggetto: [Zope-dev] Referencing a python method from a product page template
Hi,
I am defining a Zope product to create a new portlet, the portlet will display some contents retrieved from a python module.
Under the product dir I have a file queryBFE.py, with a method returnQuery(); the method returns a dictionary.
In the __init__.py at product level, there is an:
allow_module('Products.CorpQuotes.queryBFE')
The portlet page template is stored under a skin directory, properly registered in CFM.
In the portlet text, I tried two syntaxes to call the method:
a)
<span tal:define="modulo here/queryBFE;
quotazione modulo/returnQuery;">
b)
<span tal:define="quotazione modules/Products/CorpQuotes/queryBFE/returnQuery">
The first one returns:
Exception Type
AttributeError
Exception Value
queryBFE
The second one returns:
Exception Type
Unauthorized
Exception Value
