Where is that character coming from? Eh? This suggests that self.addr[1] is now broken, which means that it was previously (older Zope version) wasn't working either.. And I don't get the ^D either. Do you know how to use the Perl Debugger? I think a few debugging steps are in order here. Insert the lines import pdb pdb.set_trace() somewhere before the offending lines (for example, at 222), start Zope in debugging mode (so it won't detach from the console). Then, when you go to your site and your pdb statements are executed, you can follow exactly what goes wrong where, and why.

ANN: NotMail v0.2.0 alpha Available
by Ben Leslie 22 Nov '99

22 Nov '99

Hi everyone, After much playing around I finally have a NotMail release. This is still very much alpha but will give those who are game a chance to have a look at it, find some bugs, make some patches and give me any further suggestions for the future of NotMail. My main concern at the moment is to get this release stable and before working on extra features so this is where my priority is at the moment. I have tested this on UW Imap and Exchange servers. Please read the about document for more detailed information. Breifly features are: View MIME message Send attachments Manage messages and folders Use a readonly addressbook (readwrite soon) There are still some rough edges which I would have liked to clean up before releasing but I have exams in the follwoing week so I thought getting something out would be better than getting nothing out. Please send any bug reports to benno(a)sesgroup.net Cheers, Ben Leslie

ZopeTime() + .01 returns a DateTime object 36 minutes in the future 2. rfc822() is called on this resulting DateTime, which is a date and time string that also confirms to the RFC1123 standard.

getPropertyType returns None in ZClass
by Alexandre Ratti 22 Nov '99

22 Nov '99

Hello, I tried to list all properties in a ZClass instance and check their types. I used the following code (within the ZClass; 'infos' is a custom propertysheet name): <dtml-in "propertysheets.infos.propertyIds()"> <LI><dtml-var sequence-item> - <dtml-var "getPropertyType(_['sequence-item'])"> - <dtml-var "hasProperty(_['sequence-item'])"> </dtml-in> </UL> This is the result: title - string - 1 description - None - 0 adresse - None - 0 modele_lien - None - 0 lien - None - 0 The property names are available but all properties except built-in 'title' are described as missing (though they do store data I can retrieve and display). This doesn't happen when I run the same code on a standard object type outside a Zclass. Also, the propertyMap() method returns the correct info. Eg.: <UL> <dtml-in "propertyMap()"> <LI><dtml-var sequence-item> </dtml-in> </UL> returns {'id': 'title', 'type': 'string', 'meta': {}, 'mode': 'w'} {'id': 'description', 'type': 'text', 'meta': {}, 'mode': 'w'} {'id': 'adresse', 'type': 'string', 'meta': {}, 'mode': 'w'} {'id': 'modele_lien', 'type': 'string', 'meta': {}, 'mode': 'w'} {'id': 'lien', 'type': 'string', 'meta': {}, 'mode': 'w'} What did I missed? Thanks. Alexandre

RE: [Zope-dev] Is _getOb() best way to grab a ref to a particular object?
by Andrew Wilcox 22 Nov '99

22 Nov '99

Right, what I'm looking for is to reference an absolute object, sort of like saying "/usr/bin/sendmail" in the filesystem. The note about avoiding an acquisition wrapper by using aq_base is helpful. Hmm, I don't know why I thought I needed _getOb(). Some test I did that confused me because the result was being rendered, and I didn't realize that was happening in the publisher. I think. Anyway, let's say I want to grab /topfolder/subfolder/myobj, and I know they exist, so I'm not worried about acquisition along the way. So what I've got now is: obj = REQUEST.PARENTS[-1].topfolder.subfolder.myobj or na_obj = REQUEST.PARENTS[-1].topfolder.subfolder.myobj.aq_base Ok, that's pretty straightforward! Thanks!

Q: adding products, weird behavior
by Joerg Wittenberger 22 Nov '99

22 Nov '99

---- =_NextPart_000_01BE9BCA.1CD36B40 Hello, I'm trying to get a product straight, but I can't find how to add it's objects programatically the right way(tm). As explained somewhere (to make things worse, I can't find where I learned that anymore) I wrote a "manage_addDCDocument" method in my module, which, AFAIK, should be become a Folder method, in the hope I could use it like any other e. g., manage_addFile. When I add such an object via the web, I can actually derive instances of it (even though I've been wondering, which weird operations I have to perform inside the object constructor, to find the correct DestinationURL) but now I tried to use a script derived from load_site.py I see "manage_addDCDocument Not Found" error. The load_site.py adds new objects like this: call(object.manage_addFile, id=name, file='') Where object points to the folder, within which the new File object is to be placed. I couldn't make head or tail of the code surrounding the problem, base on wild guess (actually reading the manage_addXYZFom code of ZClass products) I found the following kludge to work around the problem. It's so terribly ugly... I beg for help: o_kludge = object.__class__(object.url+'/manage_addProduct/docstore', # ==> F***^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ username=object.username, password=object.password) call(o_kludge.manage_addDCDocument, id=name, data='') This o_kludge object shouldn't been needed. What might I have missed? For reference I attach 3 files: __init__.py : the product initialization DCDocument.py : the object class I want to use (mirrors the hirarchy in the file system and provides dublin core meta data in rdf format) docstore.py : command line tool to store and retrieve files. Any help appreciated. /Jerry -- You can have it done fast, you can have it done cheap, and you can have it done well. --- But you can only have two of those at once. ---- =_NextPart_000_01BE9BCA.1CD36B40 Content-Type: text/plain; name="__init__.py" # have fun from Globals import HTMLFile import DCDocument, Feature, User import sys from zLOG import LOG def initialize(context): perm = 'Add DCDocuments' try: context.registerClass( Feature.Feature, permission='Add IBM Features', constructors=[Feature.manage_addFeature], #icon='' ) except: print "%s: %s" % (sys.exc_type, sys.exc_value) print 'scheisse' try: context.registerClass( User.IBMUserFolder, constructors= (User.manage_addUserFolder,), permission='Add Users', #icon='' ) except: print "%s: %s" % (sys.exc_type, sys.exc_value) print 'scheisse' context.registerClass( DCDocument.DCDocument, permission=perm, constructors=(DCDocument.manage_addDCDocumentForm, DCDocument.manage_addDCDocument), #icon='' ) context.registerBaseClass(DCDocument.DCDocument) ---- =_NextPart_000_01BE9BCA.1CD36B40 Content-Type: text/plain; name="DCDocument.py" """ We add documentation here the other day.
