[Zope3-Users] Call a Python method from a ZPT

[Paolo Cilmo]

Hi, i have to call a method of a package from a ZPT.  In Zope2, i make the Poll Product (Dev_Guide 2_4). In the example i can call "getVotesFor" method simply writing in ZPT (in ZMI) this line:  span tal:replace="python:context.poll1.getVotesFor(j)"/  and it works  In Zope3, i made the same product (package). From a ZPT page (in ZMI), i can call a method of Poll if the method don't take arguments, for example with:  span tal:replace="context/poll1/getQuestion"  where poll1 is an istance of Poll package and it is in the same folder of the ZPT page. This works because the method don't take arguments, i just wan't call a method with parameters in Zope3, writing something like:  span tal:replace="python:context.poll1.getVotesFor(j)"/  Please help me.
