downloadable zope howtos and tips?
by Milos Prudek 25 Jul '01

25 Jul '01

There used to be downloadable Zope How-Tos and Tips in PDF. But the latest release is from March 2001. It looks like PDFs are no longer updated. Many people are offline most of the time, and need offline docs. Is there a way to download all current Tips and How-Tos? zope.org is not very wget-friendly :-) -- Milos Prudek

Re: [Zope] ColdFusion - I want to remain a Zopista, please help
by Ausum 25 Jul '01

25 Jul '01

Mojo, this isn't an answer to your inquiry, but an opinion regarding CF and Macromedia, facing Zope. I don't have a working knowlegde of Cold Fusion, but I did bet on Dreamweaver since the very early stages of its development - meaning the beta versions-, when nobody thought Macromedia could succeed at building a killer web designer like DW is today, because it was engineered from sratch, and we all know that when an application is written like that, the obvious risk is that users get intimidated by knew GUIs, leading them to loose interest at their fancy features. Macromedia did succeed, and now Cold Fusion belongs to them. If I were to give a simple recommendation I'd say "just stay with Macromedia. They also know multimedia, and you'll count on internet media tools, tightly integrated to all your MM previous systems, when you need them." But I choose Zope. Not because it's a standard (it isn't), not because it's easy to learn (it isn't), not because its completely documented (it isn't), but because its object oriented architecture. Zope is a very smart framework to start the building of complex applications, because when you think of a new internet app, you always think of folders and pages, not tables and adapters. I'm also aware that this extraodinary buzz on Zope wouldn't be possible if it wasn't Open Source, so that's a bonus. I don't know CF but I'm sure that you couldn't blame on them because a simple feature isn't there, because that's the software you bought, keep it or leave it :) . On the contrary, because Zope it's open, you know you can modify it until it performs exactly the way you want it, even as a development tool. The only way I'd give CF a try is when it becomes open. Would that be possible, given the fact they've already given away the Flash format?

TinyTablePlus hack to make it show in add list!!!
by Matt 25 Jul '01

25 Jul '01

I had to add the following to TinyTablePlus to make it show in the add products menu on the ZCM screen. I.e. the product installed ok and showed up in the products fine(and not borken) but I could not find a add item for it in the management screens. My first thought was that zope didn't really know that it was there to add ... so I added the following and it worked. It may not be the right thing, but it worked. I am using Zope 2.4.0a1 def initialize(context): """initialize tinytable product""" context.registerClass( TinyTablePlus.TinyTablePlus, constructors = ( TinyTablePlus.addItemForm, TinyTablePlus.addItem, ) ) regards Matt

form variable types conflicts with javascript
by Albert Ting 25 Jul '01

25 Jul '01

Form type variables are great, but it causes a problem with Javascript. Example: <input name="default" type="checkbox" onClick="setDefault(this,this.form.name:list)"> <input name="name:list" type="text"> This doesn't work, as Javascript won't recognize name:list as a variable name when calling setDefault. I've tried various combinations with no such luck. Any suggestions? Thanks, Albert

crash on import: "multiple definitions of symbol _initSplitter"
by Brenda Larcom 25 Jul '01

25 Jul '01

As per the EventFolder installation instructions, I am trying to import EventFolder.zexp into the Products folder. When I type in this filename and click Import, Zope crashes, and I see this message in the window in which I ran start: dyld: /usr/local/bin/python multiple definitions of symbol _initSplitter /usr/local/Zope/lib/python/Products/PluginIndexes/TextIndex/Splitter/ZopeSplitter/Splitter.so definition of _initSplitter /usr/local/Zope/lib/python/SearchIndex/Splitter.so definition of _initSplitter This crash is entirely repeatable. I can Add a Tutorial, which seems to import things from ZopeTutorialExamples.zexp, so I don't think the problem is with all importing. EventFolder.zexp is in the same directory as ZopeTutorialExamples.zexp, that being import in my Zope root. After a few random tries, I am not finding other products which require me to import anything into the Products folder, so I don't know if other similar products work. I cannot find any reference to this problem on zope.org, in the archives for this list, on the Zope Newbies site, in the EventFolder FAQ, or via google. So, here I am. Hopefully this is the right place. Versions of stuff that seems to be involved: Zope 2.4.0b3 Mac OS X 10.0.4, on a UFS partition python 2.1.1 EventFolder 1.31 Ideas, anyone? Brenda

25 Jul '01

Hi, I have a site-wide python script in my products directory that has a class call myClass with one string attribute called "myName". When trying to access the attribute in a ZOPE python script, I get: Unauthorized: myName How can I give this class attribute authorization? __________________________________________________ Do You Yahoo!?

RE: [Zope] Future watch: how will python division change affect z ope?
by sean.upton＠uniontrib.com 25 Jul '01

25 Jul '01

Then again, why force folks to cast when it doesn't make common sense; there is a clear divide to me between a div operation (pure integer) and a "divide" operation, and I would opt toward the common-sense interpretation of /... it only makes sense in a loosely typed scripting language... The issue of potentially braking old code, that's something else altogether... I don't see why this will affect Zope in any huge way...

IPC10 Call For Tutorials
by Garrett G. Hodgson 25 Jul '01

25 Jul '01

We're now accepting proposals for tutorials for IPC10, the annual Python conference. We had a good batch last year, and are hoping to have some equally good ones this year. Tutorials can cover any topic related to Python or its use, so graphics, networking, web, XML, Zope, etc are all fair game. Anything that you think will be of interest to a segment of the Python community. With all the changes in the language, it might be nice to have a tutorial on advanced Python usage, covering new features, OO, functional programming style, etc. Or perhaps a team-taught class that combines multiple topics to build some non-trivial application, like using wxpython and the protocol libraries to build a news/mail reader. Feel free to come up with unusual topics or approaches, or to contact me with a half-baked idea. Maybe we can turn it into something good. The deadline for submitting proposals is Monday, October 1, 2001, but it would be great to have feedback sooner if you're thinking about submitting something. For more information, please see http://www.python10.org/p10-calltutorials.html Garry Hodgson And when they offer Senior Hacker golden apples garry(a)sage.att.com are you sure you'll refuse?
