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. ;-)

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

Re: [Zope-dev] transaction support for ordering transactions.

He does tend to do that. I'd very much like a way to fix this - at the moment, the only workaround for me is for SQLSessions to have an entirely different database connection to themselves. > Ironically, I'm not sure your problem actually *needs* this fix to be > solved.

I'm not sure I understand this - are you suggesting hooking it to the database connector's commit? > *My* problem, on the other hand, is that even if I do this, ZODB does not > allow objects to be _p_jar.commit()ed twice; if you modify an object which > has already been _p_jar.commit()ed in the same transaction, you will get an > unresolvable ConflictError (because the ZODB thinks another transaction > modified the object before you). Ugh. Nasty nasty.

Thanks for the feedback - time for me to hit the source code again. :) Anthony

BerkeleyStorage.py is broken?
by nw_moriarty 06 Jun '00

06 Jun '00

There are many admonitions to use BerkeleyStorage.py if you don't require versions in a database. However, I have tried without success to get it to work with TCS.bsddb.db and BerkeleyDB 2.7.7 in a stand alone application. How ANYBODY got it to work?
