How a WebSite works using Zope?
by Raphael Ribeiro 18 May '02

18 May '02

I don't know , then i'm asking this, but is it the way i'm thinking? In your index and other pages you call your zope objects using DTML , it's like that, you create an object in zope that takes some data of your SQL Server DB, and then in your index page, you call that object that takes some data? And then the DATA appears... Another question , is: Is there any DTML editor , and how can i separarate the business logic and the front-end in ZOPE? It's like, i want to make a design , and then i want to integrate it , with my Zope website, and i don't want the codes to be a mass , how can i do it?

atexit.register() doesn't work
by Jens Wolk 18 May '02

18 May '02

Hi everybody, in a python based product (running on a Zope 2.5.0 installation) I try to implement a class which hands out unique ids. (*) The idea is to save the last id in the server's file system. To make sure that this works even if the Zope server crashed, the object should save an 'earmark' in the file system if it is destroyed in a regular way. I tried to do this with the atexit module provided by Python, but it doesn't work. (nor does __del__). Does anybody know why this is so? Or can anybody suggest a working alternative? (One working solution provided by alex.khan (*) is to patch the source code of Zope itself. But I would like to find another solution, so that others who might want to use the product, have not to fiddle with the Zope source code.) Here are the relevant parts of the implementation: class ManageGlobalZypId: def __init__(self, bucketSize, FileName): import os, thread, string, App.FindHomes, atexit ... self.opened = 1 atexit.register(self.close) def close(self): if self.opened: # save 'earmark' self.opened = 0 ... # GlobalIdHandout is the one and only object from which other objects get # their ids GlobalIdHandout = ManageGlobalZypId(256, 'GSID.txt') Thank you. Jens (*) based on an idea by alex.khan: http://www.zope.org/Members/alex.khan/GlobalSystemId?pp=1

The main reson wxpython doesnot provide the same GUI on Mac machine ( as far as I know.. infact it not ment for mac atall .. if im wrong correct me ;) ... now i mean platform independent .. which not just include Linux and Win ... I dont know how many ppl use it on Mac ( iMac ppl raise ur hands :) In fact Tkinter is also has some problem on Mac .. but it still manage. Well I'll luv to work with wxpython ..( which was earlier in my mind ) ... it gives u excellent 50 full fleged examples ... so all u got to do it Clt-C Clt-V ....In fact wxpython also support activeX ( they used IE in one of there examples) on win .. Now should u not care for thoze Apple guyz??? --------------------------------------------------- Raj Shastrakar <shastrakar(a)hbcse.tifr.res.in> ________________________________________________________________________ Everything you always wanted to know about cars and bikes,now at: http://in.autos.yahoo.com/cricket/tracker.html

Session & InvalidObjectReference
by p.t. 18 May '02

18 May '02

I'm trying to remember what was the last SQL query called registering to a session the "pointer" to a SQL instance, something like: anSQLquery = container.DB.SQL.anSQLqury Howevere, I get this error: Error Type: InvalidObjectReference Error Value: Attempt to store an object from a foreign database connection just when attempting to write to a session the variable anSQLquery. The traceback diagnostic is not very helping to me; it says: (Info: (('Products.Transience.TransientObject', 'TransientObject') referring to: Connection.py, line 345, in commit I did examine the code, but unfortunately my limited knowledge of such a sophisticated Python code gives me no possibility to uderstand what's wrong. Any suggestion on how to avoid this error message? TIA, p.t.

We're testing and upgrade from ZOPE 2.3.3 > ZOpe 2.5.1 with ZEO running We're having good success with both with only in Test environment (minimal users) Possible 3000 users hit Production ZServers Possible future problem. 1. Web site growth will cause Data.fs to become too large Solutions??? ? Mounting ZODB(s) Bottom line is... How do I prevent a meltdown of these present web sites when/if content too much for one ZServer to handle? Any and all suggestion will be gratefully accepted Eric Dunn
