Hi.

I am trying to develop a product and I need to define some kind of object having a fixed HTML structure and some extra properties. I have to provide users with an interface (into the Zope management console) to create instances, type the values for the properties, and browse the local filesystem to select the file that will be included into the fixed html structure.

In other words when they create a new product they should be given an interface where they can put values for properties and browse a file on their filesystem. When they press the button the new objetc must be made available to readers.

Can I do this using ZClass? How can I embed some predefined contents in the ZClass? How can I have the instance to handle some uploadable contents?

You should make a ZClass that inherits from OFS:File and maybe from ZCatalog:Catalogpathaware (if you want to have indexable/searcheable objects) You can add attributes through the propertysheets (types are limited to what is supported by properties (string, int, date...). You can predefine some content with the constructor (generally, a Python script that's *outside* the ZClass). --Gilles
