Collector down
by Ken Manheimer 11 Sep '01

11 Sep '01

The Zope bug collector, normally at http://classic.zope.org:8080/Collector, isn't at the moment... The machine didn't come up after some maintenance - as can happen with long running machines - and unfortunately the service provider for that machine didn't have a recent backup(!) Fortunately, we have a fairly recent backup of our own(!), which we hope to get online sometime soon. We'll be reporting back when it's back on line. Sorry about the disruption!

RE: [Zope-dev] Problems with CatalogAware?

Right now I only call index_object() after an edit, as I was assuming that after adding things would be automatically taken care fo for me, but obviously this is not the case. There are, indeed, default values in some properties within the class __init__ method. I think what is happening is that I am indexing methods (not properties), and since my factory method doesn't call an explicit reindex_object() after some properties are changed (code below) I am having problems. I wonder if I call self[id].index_object() after self._setObject(id, ad) if that will do the trick? Thanks for the reply, Sean def manage_addAdItem(self, id, title, REQUEST=None): """Zope managment interface create method for AdItem""" ad=AdItem(id) ad.setId(id) ad.setTitle(title) if REQUEST is not None: ad.setAdBody(REQUEST['adBody']) if (len(REQUEST['keywords']) > 0): ad.setKeys(REQUEST['keywords']) ad.setAdDateMulti(yyyy=REQUEST['Adyyyy'], mm=REQUEST['Admm'], dd=REQUEST['Addd']) ad.setRtDateMulti(yyyy=REQUEST['Rtyyyy'], mm=REQUEST['Rtmm'], dd=REQUEST['Rtdd']) ad.featureURL=REQUEST['featureURL'] self._setObject(id, ad) if REQUEST is not None: return self.manage_main(self, REQUEST) -----Original Message----- From: Toby Dickenson [mailto:tdickenson@devmail.geminidataloggers.co.uk] Sent: Monday, September 10, 2001 6:28 AM To: sean.upton(a)uniontrib.com Cc: zope-dev(a)zope.org Subject: Re: [Zope-dev] Problems with CatalogAware?

However it does not automatically reindex if properties are changed. It sounds like your index might contain the default (initial) values for these properties. Do you need to add a call to reindex_object() after changing them from the defaults? Toby Dickenson tdickenson(a)geminidataloggers.com

Getting Unauthorized from __bobo_traverse__.
by Erik Enge 11 Sep '01

11 Sep '01

Hi! I've have this custom __bobo_traverse__ hook: def __bobo_traverse__(self, REQUEST, name): """Intercept the traversal""" if name: if hasattr(self, name): return getattr(self, name) When I call the object like this: /objecta ie. using __call__ (I guess); everything is ok. It renders the index_html (which is a DTMLFile) as expected. However, when I do this: /objecta/index_html it raises an Unauthorized on me. I can't understand why. I thought it might have something to do with docstrings, so I tried this: def index_html(self): """we have a doc string""" return DTMLFile('index_html', globals()) And that worked (it didn't render the DTML, but I know how to fix that). Making it go back to this: index_html = DTMLFile('index_html', globals()) raised an Unauthorized on me again. Here's the full traceback: Traceback (innermost last): File /home/erik/development/zope-farm/Zope-2.3.1-src/lib/python/ZPublisher/Publish.py, line 223, in publish_module File /home/erik/development/zope-farm/Zope-2.3.1-src/lib/python/ZPublisher/Publish.py, line 187, in publish File /home/erik/development/zope-farm/Zope-2.3.1-src/lib/python/ZPublisher/Publish.py, line 171, in publish File /home/erik/development/zope-farm/Zope-2.3.1-src/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: object_manager_index) File /home/erik/development/zope-farm/Zope-2.3.1-src/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: object_manager_index) File /home/erik/development/zope-farm/Zope-2.3.1-src/lib/python/Shared/DC/Scripts/Bindings.py, line 324, in __call__ (Object: object_manager_index) File /home/erik/development/zope-farm/Zope-2.3.1-src/lib/python/Shared/DC/Scripts/Bindings.py, line 354, in _bindAndExec (Object: object_manager_index) File /home/erik/development/zope-farm/Zope-2.3.1-src/lib/python/App/special_dtml.py, line 236, in _exec (Object: object_manager_index) File /home/erik/development/zope-farm/Zope-2.3.1-src/lib/python/OFS/DTMLMethod.py, line 182, in __call__ (Object: standard_html_footer) File /home/erik/development/zope-farm/Zope-2.3.1-src/lib/python/DocumentTemplate/DT_String.py, line 538, in __call__ (Object: standard_html_footer) File /home/erik/development/zope-farm/OtherProducts/WarpFramework/user.py, line 89, in on_access (Object: api) File /home/erik/development/zope-farm/Zope-2.3.1-src/lib/python/OFS/Traversable.py, line 223, in restrictedTraverse (Object: api) File /home/erik/development/zope-farm/Zope-2.3.1-src/lib/python/OFS/Traversable.py, line 190, in unrestrictedTraverse (Object: api) Unauthorized: index_html I also tried adding: __allow_access_to_unprotected_subobjects__ = 1 just for good measure, but that didn't help either. Any help on this is greatly appretiated. :-)

Pre-process a REQUEST before Zope does anything else
by Dario Lopez-Kästen 11 Sep '01

11 Sep '01

Hello! I am, uh..., reluctant to dig thru more code that I allready have, so if some one has an easy answer for the following I'd be a gratefull :-) For my user_folder product project(*), I need to be able do some processing for each and every request that is sent to zope to determine some enviromental thingies, *before* the request is processed by the main zope mechanisms. I would like this to happen transparently (i need to check into a database and do some time-out calculations to determine whether the session is still valid). Is there such a hook in AccessControl or in any other place? How to the various sessionmanagers deal with this? Thanks, /dario (*) it's not a new one, it's a customisation of an existing, and code will be provided to the original author so he can decide if it should be or not included in the product. - -------------------------------------------------------------------- Dario Lopez-Kästen Systems Developer Chalmers Univ. of Technology dario(a)ita.chalmers.se ICQ will yield no hits IT Systems & Services

Declaring interfaces for Products
by Dario Lopez-Kästen 10 Sep '01

10 Sep '01

Hello! I am making a product using the Interface approach described in the ZDG. As I understand it, Interfaces should expose all methods that provide funtionality for my product, with the possible exception of internal methods used as utility methods in the class itself. Is this correct? Apart from using security declarations, I want to make some of the methods available thru the web (TTW), and some of the methods not publishable TTW. In order to be able to publish a method TTW, they need to have a docstring, right? Now, in my interface defintion I want to provide doc-strings for all methods that are exposed (the interface), but not all them are to be publishable TTW. Can I achieve this by using docstrings for my methods in the Interface, but not in the Implementation, or do I need to omit the doc-string in both the Interface and the Implementation? Example of what I mean: --<begin sample code>-- <<<file: ya_UserFolder.py>>> class ya_UserFolder(Base): "Yet another User Folder Interface" def getUserName(self): "Provide a lusername" ... def authenticate(self, password, request): "Authenticate a luser" ... <<<file: ya_UserFolderProduct.py>>> from ya_UserFolder import ya_UserFolder class ya_UserFolderProduct(...): "Yet another User Folder Product Implementation" __implements__ = ya_UserFolder def getUserName(self): "Provide a lusername - has doc-string TTW Callable" ... def authenticate(self, password, request): # No doc-string, not callable TTW ... --<end sample code>-- Thanks, /dario - -------------------------------------------------------------------- Dario Lopez-Kästen Systems Developer Chalmers Univ. of Technology dario(a)ita.chalmers.se ICQ will yield no hits IT Systems & Services

Password encryption--calling on the community
by Shane Hathaway 10 Sep '01

10 Sep '01

Following the Zope 2.5 plan, I have just added to CVS the capability for user passwords to be encrypted in the standard user folder. Please try it out. If it works correctly there should be no outwardly visible differences. I'm also soliciting the assistance of developers and users of custom user folders (like LDAPUserFolder, LoginManager, GUF, etcUserFolder, NTUserFolder, etc.) We need you to test whether the added feature has any bad effects on your user folder. It's much easier to apply a fix now than it will be after a release. Shane P.S. I may have inadvertently sent this twice, please excuse. :-)

Alternative acquisition workarounds
by Sidnei da Silva 10 Sep '01

10 Sep '01

Hello everyone! This is my first posting to this list, so, excuse me if im asking a question that has already been asked by someone. Ok, lets go to the point: I have the following structure at my site: /-- | --/Template1 | --/header --/footer --/images | --/image1.jpg --/image2.jpg --/image3.jpg | --/Section | --/Template 2 | --/images | --/image1.jpg And I tried using Transparent folders to make documents using the Template2 acquire Images and Methods from the Template1, but when i use a DTML document that references "images/something", my document uses the images dir from the Templates2 and ignores that from Templates1. Ive seen an example like this in some acquisition tutorial out there, but it just said that this was hard to implement and shows some example in DTML. I was hoping someone implemented anything like this in a Python product, or if someone has an idea of how this could be implemented in Python. Thanx for your patience. -- Sidnei da Silva X3ng Consultoria e Desenvolvimento Ltda. sidnei(a)x3ng.com.br

Where to send patches?
by Jim Washington 10 Sep '01

10 Sep '01

Hi, All Since the Collector is down, where do we send patches if we are not cvs-authorized? I just discovered a not-too-clever hack to make the Find tab recurse through methods of Z Classes, which the margin of this e-mail is too small to contain. -- Jim Washington

Problems with CatalogAware?
by sean.upton＠uniontrib.com 10 Sep '01

10 Sep '01

I have a python product that has a class derived from CatalogAware and Folder. I programmatically add instances of these (1000s of them) on an automated basis every day in the early morning. My problem is that whenever I do this, the Catalog is updated with some problems: 1 - Metadata is skewed: DateTime objects are cataloged, and they end up with the wrong date ('2001/01/01') instead of today's date, even though the actual property contains today's date. The index in question is built from a property. 2 - Text indexes only get a portion of their text stored in the metadata, not all of it. The index in question is built from a class method in the product code. Using a bulk reindex solves this problem (subtransaction off, haven't tried it any other way). I'm using Zope 2.3.2 with ZEO 1.0b3 using a VHM. The automated process queries SQL for data, and uses those queries to create object instances of the previously mentioned catalog-aware class, and I create anywhere from 2000-7000 objects at a time. I'm not sure if this is due to the size of the transaction I am running. I haven't tried this in a smaller transaction yet; I was wondering if anyone else has seen this. Any thoughts?
