We look at Plone and go alright, how do we make it do less? how do we turn this thing off, and this thing off, and this thing off, and this thing off? why is it so slow? and it still doesn't do the page we need to do. Let's just write our own CMS. * Apparently many people disagree with you. Google hits: **27,700,000* for **Plone ***23,600,000* for **Zope** *14,800,000* for **Zope -Plone** For small companies that needs a small subset of what Plone can do, Plone might be a bit big. But for consultants/developers like me it is *far* easier to use Plone, remove some features and add those that are missing. A fully finished system, that end users can install and try out, is the biggest succes story of Zope. There *must* be a lesson in that somewhere. That Plone is difficult does not reflect that a big integrated system is the wrong way to go! It only indicates that the Zope/CMF/Plone stack is too big. Which is exactly why Zope 3 was developed, and I can hardly wait until something like Plone is running directly on Zope 3. Then we will both have a big hunking end user system and a clean development model. I know that something like Plone isn't the best solution for everything. Eg creating a task based intranet is impractical. But its still the most succesfull approach so far. Plone has become a very precise communication tool between programmers. If your product works in a straight Plone installation, it can be modified with known patterns by other developers. If everything is fragmented we will loose this unification by example and setting up big systems will be a lot more difficult. -- hilsen/regards Max M, Denmark http://www.mxm.dk/ IT's Mad Science ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
Re: [Zope3-Users] PyWebOff
Shane Hathaway wrote: Hello, I've been assigned to present Zope in a local upcoming Python user group meeting. As part of the assignment, I'm supposed to solve the PyWebOff challenge using Zope: http://pyre.third-bit.com/pyweb/challenge.html I'd like to do this using Zope 3. However, I'm really struggling. I feel like I must be using Zope 3 in a really dumb way, because the code so far is highly repetitive, completely dependent on Zope, and more XML than Python. This is not going to go over well in the presentation. Can anyone tell me how to do this better with Zope 3? Maybe my Zope 2 experience is preventing me from seeing something obvious. I've attached the __init__.py and configure.zcml that I created in a package called challenge. I agree, the __init__.py and configure.zcml are pretty dry reading. I reckon you could start your PUG presentation from the end (so to speak) by presenting one (or more) doctests. One you have your captive audience, then go the the start. Take a Test-Driven-Development approach. It's easy to disgest an application (and zope) in test case sizes. And as each need arise, bring in the appropriate ZCML to showcase it value. This may help distill the python, zope and zcml. -Tom ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
[Zope3-Users] ZODB - ways of storages?
Hi, in the book Web component development with ZopeX3 by Philipp von Weitershausen on page 72 I find the following statement: The ZODB can store persistency data in many ways. The most common storage is FileStorage which stores data in a file usally called Data.fs By using a different storage backend, you can choose where and how you would like to store persistent objects. ZODB even supports a network storage system calles ZEO So I expect, ZODB is only a front-end for different ways of storage like file, oracle db, isn't it? If yes, I would like not to change the code (of persistent class) to change to another storage way, is that correct? Thanks a lot! ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
[Zope3-Users] ForbiddenAttribute add error
Hi, I get this error
ForbiddenAttribute: ('add', zope.app.publisher.browser.viewmeta.+
object at 0x754d09ac)
when I try to add a Claim to a DebtManager (both are subclasses of
Folder) at http://localhost:8031/DebtManager/+/@@AddClaim.html
The addform looks like this:
browser:addform
schema=debtman.interfaces.IClaim
content_factory=debtman.debt.Claim
label=Add Claim
name=AddClaim.html
fields=title description debtor creditor amount
permission=zope.ManageContent
/
and the content type declaration looks like:
content class=.debt.DebtManager
require
permission=zope.ManageContent
interface=.interfaces.IDebtManager /
require
permission=zope.ManageContent
interface=.interfaces.IDebtManagerSchema /
require
permission=zope.ManageContent
set_schema=.interfaces.IDebtManagerSchema
/
require
permission=zope.ManageContent
attributes=add
/
require like_class=zope.app.folder.Folder /
/content
The permission require for add is just an attempt to get rid of the
error. I've asked around on #zope3-dev, but no one knew.

[Zope3-Users] How do I start Zope?
At this point I have: Upgraded to Python 2.4.2 and confirmed that it works by launching IDLE and seeing the correct version number Run the installer Zope-3.2.0.win32-py2.4.exe The old documentantion shows various bits about setting a username and password for the administrator, etc, which I do not get. No surprises, this looks to be a major update to Zope from 2.x, which seems to be what all the manuals document. I looked at the various README.txt files because the page where you download the installer says it is supposed to tell me how to do the installation. There are lots of README.txt files. I assumed this meant C:\Python24\zopeskel\README.txt, but that tells me nothing about running Zope. The version I installed just to look at ages ago, 2.5 or something?, was easy to start and I did just that before looking for updates. How do I start Zope so I can get to the Management screen or whatever and start doing some real work?

You will required to give permission for 'IClaim' inteface.
Something like::
content class=debtman.debt.Claim
implements
interface=zope.app.annotation.interfaces.IAttributeAnnotatable
/
factory
id=debtman.debt.Claim
description=A Claim.
/
require
permission=zope.ManageContent
interface=debtman.interfaces.IClaim/
require
permission=zope.ManageContent
set_schema=debtman.interfaces.IClaim
/
/content
If you implemented a container interface (say, IClaimContainer)
along with IClaim in debtman.debt.Claim, then you have add::
require
permission=zope.ManageContent
interface=debtman.interfaces.IClaimContainer/
