I used to be a fairly knowledgable zope user many years ago, but things have moved on and I've forgotten most of what I know. I have a largish library of python modules which define a number of classes which have methods that perform work in a product. Currently, much of the system is managed vai commandline tools which utilize the library. We want to ad a web interface, and I figured zope would be a natural, since everything is already in python. I created external methods which return instances of classes, but if I try to use those instances from within dtml (iterating over a list of them, for instance), I just get prompted for authentication credentials. I seem to recall that there was some way of applying zopishness to external object instances at runtime, but I can't remember what that mechanism is, and I couldn't find it in either the zope book or the zope bible I went out an bought. For example, if I have a customer class which has name, id, and revenue members, and I create an external method to return a list of customer instances, I cannot do the following <dtml-in extListCustomers prefix="cust"> <dtml-var expr="cust_item.id"> <dtml-var expr="cust_item.name"> <dtml var expr="cust_item.revenue"> </dtml-in> Thanks --sam
