Spliting text
by Michel Pelletier 06 Apr '00

06 Apr '00

I'm trying to think of some good ways to improve the way ZCatalog splits text. The component that does this is called the Splitter, and it is currently written in C. In the CVS there is a new mechanism for abstracting out language dependent features, like splitting, into various Vocabulary objects. I want to make it as trivial as possible for an average programmer to create Vocabulary objects for their language of choice. Right now there are some prototypes doing Japanese, and I and the guys at Digital Garage have done some research on the similar Chinese problem. I am contemplating checking in Brian Hooper's ExtensionClass patch to the Splitter, so that the splitter can be subclasses in python. While more useful, I don't think this will gain much; the Splitter is very english centric and not very extensible (to solve, for example, the japanese problem) and subclassers would need to re-implement most of it in python anyway, so there is no big win. I think that the existing C splitter should be internationalized. I would like some suggestions on how people think the lexical analysis problem is solved for their particular language, and I'd like to discuss how to generalize the Splitter on the Interfaces Wiki: http://www.zope.org/Members/michel/Projects/Interfaces/Splitter Can someone post this to the ZIP list? I'm not on it at the moment... -Michel

Problems with Inheriting a contained ZClass.
by Brian McGinnis 06 Apr '00

06 Apr '00

Hello, Here is the scenario. I have ZClass A, which contains ZClass B. Now ZClass C is a subclass of A. >From within C I now try to create another ZClass D and I want to make D a subclass of B. Simple right. The problem is that D ZCLASS create form doesn't display ZClass B as class from which I can subclassed from. Is there some secret to getting this to work or is this something that can't or shouldn't be done. Thanks in advance, Brian McGinnis

RE: Week of the year

Zopsters, In case anyone cares, <dtml-var expr="((ZopeTime().dayOfYear())/7) + 1"> gives you the week of the year and will allow for tests to see if DateTime's occur in the same week. I was just looking to see if it was in a module. All my best, -- Jason Spisak 444(a)hiretechs.com

I've put together a brief summary of the Java security model for comparison with Zope's present and future security models: http://www.zope.org/Members/jim/ZopeSecurity/JavaSecurityModel This is based on pretty limited research. If I've gotten anything wrong or missed any important points, please add comments or corrections. (Note that the above URL points at a wiki page, which you can edit if you are a member of zope.org.)

add optional "folder" argument to ZClass.createInObjectManager() ?
by bruce＠perens.com 06 Apr '00

06 Apr '00

Hi, I propose to add an optional argument to ZClass.createInObjectManager() that specifies the ObjectManager instance in which the newly-created object will reside. Currently, the ObjectManager in which an object is to be created is found through acquisition. This breaks when sub-objects are created in the constructor of their container object. For example: I have a Purchase object containing Item objects. In method PurchaseClass_add(), I create the Purchase object using PurchaseClass.createInObjectManager(). That goes fine. Then I create its contained objects using ItemClass().createInObjectManager(). Instead of going inside of the PurchaseObject, they go in the folder that contains the PurchaseObject. No manipulation of name spaces by <dtml-with> will change this - the ObjectManager is found through acquisition, not the name space. Currently, the only way out of this is to create an external method and call _setObject() directly. You can't do it from DTML at all. I propose to add a "folder" argument to createInObjectManager() so that the folder can be specified directly. The modified method appears below, please compare it to the version in ZClass.py . I have a few questions about this: 1. Am I missing an easier or more elegant way to do this? 2. Would this circumvent security in some way? 3. Can I get this change, or something that has a similar effect, into a future version of Zope? Thanks Bruce def createInObjectManager(self, id, REQUEST, RESPONSE=None, folder=None): """ Create Z instance. If called with a RESPONSE, the RESPONSE will be redirected to the management screen of the new instance's parent Folder. Otherwise, the instance will be returned. """ i=mapply(self._zclass_, (), REQUEST) if not hasattr(i, 'id') or not i.id: i.id=id durl=None if folder is None: if hasattr(self, 'Destination'): d=self.Destination if d.im_self.__class__ is FactoryDispatcher: folder=d() if folder is None: folder=self.aq_parent if not hasattr(folder,'_setObject'): folder=folder.aq_parent folder._setObject(id, i) if RESPONSE is not None: try: durl=self.DestinationURL() except: durl=REQUEST['URL3'] RESPONSE.redirect(durl+'/manage_workspace') else: return folder._getOb(id)

Zopsters, I looked in DateTime, and didn't see this. Is there a way to get week of the year? As in: This week is week number 18th week of the year. I don't want to code it if it's done already. All my best, -- Jason Spisak 444(a)hiretechs.com
