getUserById
by Stefan H. Holek 14 Dec '04

14 Dec '04

In User.py the method is defined as def getUserById(self, id, default=_marker): try: return self.getUser(id) except: if default is _marker: raise return default I am wondering whether anybody actually depends on the fact that getUser is supposed to raise an exception. I know of no user folder implementation that actually does that. Rather, I'd like to change it to the way it's done in LDAPUserFolder where the method looks (more or less) like: def getUserById(self, id, default=_marker): user = self.getUser(id) if user is None and default is not _marker: return default return user Any objections?

Call for Offers: Zope training during Spring 2005
by Dario Lopez-Kästen 14 Dec '04

14 Dec '04

[This is a general call for offers to interested parties. Apologies for the cross-post] Greetings, my organisation needs to hold one or more sessions of Zope training to meet current and future development and deployment needs. We use Zope as one of several (Web-)Application frameworks, and we typically need to interface and cooperate with external data sources (for example, User Management with Kerberos and other external User Sources providing user data - meaning we cannot base our UserFolders' data on Zope alone). We will have a group of 8-12 people, most - if not all - experienced developers who will need to learn how to develop Applications on Zope, CMF, Plone and CPS. Participants can be assumed to know how to develop in Python (we will make sure of that). We also want to focus on efficient ways to make Zope talk to Oracle, LDAP and MySQL (in that order) in an efficient and speedy manner, and how to develop high-speed, clusterable (ZEO) solutions with Zope-based technology. At the end of the course(s) we expect the participants to be able to have a thorough understanding of what kind of frameworks Zope, CMF, Plone and CPS are, what their differences and their similarities are. We also expect participants to know how to customise, adapt and develop applications based on Zope, CMF, CPS and Plone, how to develop add-ons to the above and how to develop Products that work with all of CMF, CPS and Plone. To clarify, we also expect participants to be tought development techniques with File System based tools - not only on the Product level but on a solution level (i.e. all customisations, etc, of a site should be script/FS based as well). The course(s) are scheduled to be held in March-April and possibly May, at Chalmers University of technology, Göteborg, Sweden. We are not exclusively looking for a single party to provide courses for all of Zope, CMF, CPS and Plone; for example, you are welcome to offer training that only covers Plone or CPS. While many of our participants can read and write english very well, they may be untrained in communicating verbally in English. It is therefore a plus if trainers are fluent in Swedish - it is an absolute requirement that trainers have good English communicative skills. Please send your initial proposals per mail to the following address: zope-training(a)ita.chalmers.se Please specify the following: - Acceptable number of particiants - What parts you are interested in - A draft description of the training contents - As estimate of the amount of work required from participants - Your estiamte on how many sessions are needed - Preliminary budget If you have any questions regarding this offer, please contact me directly at dario(a)ita.chalmers.se.

FlashMovie
by Krzysztof Kubacki 13 Dec '04

13 Dec '04

Hallo I have added new product named "FlashMovie". I'm adding new FlashMovie's object in Zope's folder and next I want to get it from ZTP: <table tal:define="img python:getattr(here, 'FlashMovieObject', None)">. After it ZPT is being redirected to ZPT named "flashmovie_view". I can not find in a ZMI the place where I can change it. I don't want to be redirected. Thanks in advance Krzychu

Re: [Zope-CMF] opaque items, events

Directing to Zope-dev as this is not CMF-specific.

Yes but I'm talking about existing points where hooks are needed. But indeed the semantics for edit events have to be devised. In the context of CMF we have a central point (reindexObject) that mostly does it.

Zope+PIL+ image resizing
by Krzysztof Kubacki 06 Dec '04

06 Dec '04

Hallo. I have Zope 2-7-0 on Linux platform and the following problem :) I'm sending an image through form on the pythonScript. I want script to resize image and save on the zope folder in 3 different size. OK, I use ExternalMethod which uses PIL library to resize these images. External method: def xImageScale(img_file, maxx, maxy): from PIL import Image from cStringIO import StringIO im = Image.open(img_file) im.thumbnail((maxx, maxy), Image.ANTIALIAS) out_file_str = StringIO() im.save(out_file_str, im.format) out_file_str.seek(0) tmp=out_file_str.read() out_file_str.close() return tmp pyrthonScript: cAnimation = form.get('cAnimation','') # image from the form if cAnimation: o.invokeFactory(id='cAnimationS.'+timeStamp, type_name='Image', file=context.xImageScale(cAnimation, 100, 100) o.invokeFactory(id='cAnimationM.'+timeStamp, type_name='Image', file=context.xImageScale(cAnimation, 200, 200) o.invokeFactory(id='cAnimationB.'+timeStamp, type_name='Image', file=context.xImageScale(cAnimation, 300,300) The result is "IOError, cannot identify image file". So, when I want to resize and save only one image it works properly. Thanks in advance for any help KK

permission management behaviour
by bTurtle ZOpe 03 Dec '04

03 Dec '04

Hi in a product I am working on, I have to set the permissions. I tried this, using the following code snippet: roles = object.valid_roles() object.manage_acquiredPermissions(permissions['Acquire']) for role in roles: object.manage_role(role, permissions[role]) permissions is a dictionary of roles with lists of permission names (e.g. {'Authenticated': [], 'Acquire': ['Access Transient Objects', 'Access arbitrary user session data', ...}). The thing I don't understand concerns the 'Manager' role. I observed the following things: - if I ommit the call to manage_acquiredPermissions, the permissions for 'Manager' are not set - 'Manager' inherits all permissions of Roles that are set AFTER the 'Manager' role is set (with manage_role). e.g. 'Owner' has the 'Add Database Methods' permission set. When the 'Owner' role is managed, the Permission 'Add Database Methods' is also added to the 'Manager' role. ('Owner' comes after 'Manager' in the roles list). Can someone explain why this is so? or what I am doing wrong. my setup is: Zope Version (unreleased version, python 2.3.3, linux2) Python Version 2.3.3 (#1, Apr 6 2004, 01:47:39) [GCC 3.3.3 (SuSE Linux)] regards Stefan

CatalogBrains.getObject and unrestricted code
by Florent Guillaume 29 Nov '04

29 Nov '04

In ZCatalog's brains, getObject currently does a restrictedTraverse to get the object. That's a problem for unrestricted code that needs to get to the object nevertheless, even if the user cannot get to it. For instance CMF is impacted, when it tries to reindex the security of all subobjects of a given object. Unless someone is opposed to it, I'll add a _getObject method that does an unrestrictedTraverse, and make CMF use it if available.

including docutils in Zope -- two issues: IP and location
by Jim Fulton 29 Nov '04

29 Nov '04

I can understand the desire to include docutils in Zope. We made this decision for Zope 3 a while ago. Such a decision needs to be made *very* carefully for intellectual property reasons. Contributors other than Zope Corporation employees can only check in *their* code. This is important to reduce the risk of an IP problem. This means, unfortunatelky, that third-party code puts a burden on Zope Corporation, and thus, the community, since we become a bottle neck. Whatever we do with distutils, we have to make sure that Zope Corporation is involved and that ZC employees check in any code changes. (I assume that Andreas was a ZC employee when this code was originally checked in.) WRT location, I'd like to keep things as simple as possible. Top-level packages in the Zope 2 tree should be in lib/python. This is what was done for Zope 3 and it has worked well. Andreas, I'd be happy to sort this out with you off line if you like. Perhaps we can do with Zope 2 what we did for Zope 3, and, for Zope 2.8, perhaps we can even share the same tree. Jim -- Jim Fulton mailto:jim@zope.com Python Powered!

Removing XML export from Zope 2.8
by Andreas Jung 26 Nov '04

26 Nov '04

Any objects to kick the XML export from Zope 2.8 entirely? This feature is broken since ages and no one cares about it or is able/willing to fix it. It does not seem in use by anyone and it appears to me as a very useless feature. Any comments? Andreas
