Recursively adding ZClasses (continued)
by Rik Hoekstra 07 Jun '00

07 Jun '00

Could someone help me understand adding adding ZClasses a bit further? First I had a problem with nested ZClasses, which got me into trouble when I wanted to add ZClasses to each other. So I followed the 'common wisdom' of adding all ZClasses at the top level of the product. THis generally works OK, and you can add ZClass instances to each other from the management interface. So far so good. WHere things go wrong is by recursively adding ZClasses, as in: the following pseudo code for ParticularZClass with some NestedZClasses inside: (<Particular ZClass> constructor has the following action sequence): create ParticularZClass instance set some properties in somelist set some other properties into REQUEST create NestedZClass instances whatever reading and following every piece of documentation I could get on this (not much), I never got any further than adding the NestedZClasses instances on the _same_ level as the ParticularZClass. No <dtml-with "manage_addProduct['whatever']"> (which contrary to documentation should have the containing product and not the ZClass as the 'whatever' argument) could help me out. The only workaround is to create the ZClass in an auxiliary product, in which case the recursive adding does work. Could someone explain what is happening here (apart from that it's a bug)? And yes, I'll add it to the Collector. Rik

LM and user objects
by Bill Anderson 07 Jun '00

07 Jun '00

Pardon my denseness (politics can do that to you I guess ;)... I beleive I have the basic LM concept grasped. I understand that I need a 'User' Object, ostensibly can be done in Python or ZClasses. For now, I will look at ZClasses for experimentation. So, I beleive that to set up a ZODB-based User for LM, I need to create the UserObject's ZClass. What do I need to subclass, if any, from? Once I get that set up, I add property sheets for the user where? The ZClass? Once I get that set up, how do I add a user? Would one method be to go into the acl_users(LM) and add a User? What about adding them programmatically? I looled at the API.txt, but it wasn't helpful in this regard. :( I swear if nobody beats me to it, I'll write all this up and post it to Zope.org when I get it done. :) (If nothing else, for my own reference ;)

Containers in ZODB
by Petr Knapek 07 Jun '00

07 Jun '00

Hi Zopists, I would like to use ZODB3 as an object DB to store my own objects. At the beginning, I will make any text UI but later I want to put my objects into a ZOPE Folder and store them inside ZOPE ZODB (Zope will serve as GUI). Generaly I have 2 types of objects: Container - object with some attributes and methods which can collect other objects (also Containers) Item - an object with some attributes and methods which can not collect any other objects but can be contained in Container My questions are: 1. Does anybody know what the essential Zope classes from which I have to inherit are? Of course I know the Persistent is essential for both of them but don't know whether it is sufficient for future import of my own ZODB as a part of Zope ZODB. 2. Does anybody know how to import my own ZODB (*.fs file) into Zope ZODB? I don't need to have any tabs in the web browser connected with my objects I only need possibility to store these objects inside Zope and call their methods. Please can anybody react on this it is very important to me, it is my project and I want to use ZODB.

FWIW, ZCVSMixin now at 0.0.9... and rising. ;-)
by Steve Spicklemire 07 Jun '00

Hi Folks, ZCVSMixin is now reaching a 'useful' state... at least for managing objects in a single folder at a time. I haven't yet tackled recursive folders etc... I've been running two zope sites, checking in chages on one site... checking them out on another. Esp nice is being able to say: cvs update -r Rel-0-0-5 thisMethod.xml thatMethod.xml etc..... Anyway.. http://www.zope.org/Members/sspickle/ZCVSMixin -steve

Getting to container from a method called by the factory
by Kevin Dangoor 07 Jun '00

07 Jun '00

I'm trying to check if the container from which the user selected a product from the add menu has an "acl_users" folder. When the user selects the option from the add menu, they get a form. When they submit the form, the method (a PythonMethod) does this: folder=self.Destination() if hasattr(folder, 'acl_users'): ...do something... else: ...complain... Even though I know the folder has an acl_users (and having this function return folder.objectIds() proves it), the above code will always complain. Is there a problem with using hasattr in this context? Kevin http://www.byproducts.com - Humor and Novelties

by Jason Spisak 07 Jun '00

Michel, I was just browsing the help system and can I just say it is terrfic. The .py files especially. Not that python isn't that easy to read, but having the ZQR type stuff handy online is a huge win. Is that stuff updated fro mthe source on the fly?

I was kicking the idea of making one around, but I don't think I'll have time to do it. There's a document on how to write a Zope database adapter by Chris Petrilli at: http://www.zope.org/Members/petrilli/WritingADA Since the Python layer has been (well) done by Alex, it shouldn't be too hard to make one if you're OK with Python.

Hi Zope-developers, I try out Zope last week and was greatly impressed with the flexiblity of the zope system. Now, I am thinking of porting my Company intranet to zope but I have one problem. Our company backend database servers (for items catelogs, leave application ...etc) sits on Inprise Interbase server. I check through all the mailing list and unable to find an adapter to it. Currently, I notice that Inprise has made Interbase an open source database system on linux. Is there anyone looking into coming out with an adapter on Interbase ? Or someone in the developing labs can give me guidelines on how to write an adapter for Inprise Interbase on linux. I manage to get a copy python code that can access Interbase server on linux. Credit has to be given to Alexandra (email :'alexan(a)misha.micex.com'). Need advise ... bye ... kyn

Interfaces Wiki Changes
by Chris Withers 07 Jun '00

07 Jun '00

Hi Michel, I've been good and documented what I learned from the docs discussion in the interfaces wiki. Can you check and correct as appropriate please: http://www.zope.org/Members/michel/Projects/Interfaces/ACPermissions http://www.zope.org/Members/michel/Projects/Interfaces/QueryObject Also, could the case sensitivity of each of the index types (text|keyword|field) be documented in the Wiki? cheers, Chris
