[Zope] Composite Objects?
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hey all, I'm attempting to use mostly-vanilla Zope to implement an intranet here at my office, but am finding it difficult to use a 'feature' that I imagine should be possible. I've created a template for what ideally would be a single object/class type, containing multiple different kinds of Zope objects, and want to be able to clone new copies of that template as one can do with the existing Zope objects (e.g. as one would add a new File or Folder). The template currently consists of a typical index_html ZPT, a Formulator form, a small collection of Python Scripts, and two generic Files which are the CSS and JavaScript includes for the ZPT. These are all contained in a normal Folder object. The ideal situation is that I want a single object, which has various data fields (storage location is not important at this time) that are manipulated with the above objects--the ZPT+files generate a form page, using Formulator for rendering and validation, and the Python scripts for various other tasks, including the eventual input processing. And, as stated before, I need to be able to instantiate new copies of this object. Now, I first looked at ZClasses (which according to the Zope Book is exactly what I want), but it appears that each ZClass instance shares the 'methods' in the ZClass definition--so that if I wanted each individual object to add fields to its own Formulator form, it couldn't. On top of that, I read and (mostly) understand some of the recent discussions here about possible deprecation of ZClasses, making it even less of a desirable option. I then looked at CPSSchema, but what appears to be its homepage on zope.org cannot be accessed even after one creates an account on the site; furthermore, what little I was able read about it suggests that it too is not quite what I'm looking for. Ditto for Plone's ArchTypes (plus I'd *rather* not have to use Plone, as this intranet is not really going to be a CMS in the classical sense). So, I'm pretty much out of ideas; obviously I could just write my own Product from scratch, and that's what I'll be looking into in the meantime, but this seems like something that should be possible, and I hope I'm just missing something or being misled by what I've already read. Please help :) Regards, Jeff - -- Jeffrey E.

But when trainning with my first Zope Scripts I can't. The dir not defined error appears. ??? Being a relative newbie myself, I'm not positive this is correct, but I can tell you that Python Scripts are limited in Zope--you can't access the entire set of normal Python libraries and functions. A large part, yes, but not all of them. I'd be surprised if 'dir' was not in the allowed functions, but that would be one reason why it's claiming it's not defined. - -- Jeffrey E.

Make it folderish so it can contain Forumator forms and anything else you want: inherit from Folder and use its UI to manage contents. You could then use AbracadabraObject to clone instances of this thing; or you could do it all in code and have a manage_afterAdd method that adds a preconfigured Formulator form. Source and/or docs of Formulator should give you a clue how to instantiate one with the right config. That's kind of what I was thinking. AbracadabraObject appears to have a method call that allows you to use its magic in code, which I think is exactly what I want, although as before I'm very surprised that this sort of functionality doesn't exist in Zope proper. I guess my desires aren't actually all *that* in-line with the main body of Zope users, as I do *not* want the users of this application to ever see a ZMI screen. So I need this half-and-half situation where I or another admin can tweak some aspects of a class (e.g. Formulator forms, ZPT) via the ZMI or WebDAV, but the instances of those objects are instantiated *via code only*, by Python logic and my own (ZPT-driven) HTML form interface. Another possibly far-fetched feature I'd like, which again I believe was part of ZClasses, would be to be able to tweak the instances' Formulator forms after the fact...e.g. add another data field a year down the road. Of course this then means that I both do and don't want these cloned forms to match up with the central one, and I'm not at all sure that I can accomplish this without writing lots of my own code to handle it. Thanks for the help, by the way, it's appreciated.
