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)

Access to "week of the year"

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

Embeding docs with dtml
by Carlos Neves 05 Apr '00

05 Apr '00

Hi, i'm trying to embed a dtml document in a child folder with a dtml method, like this: - I have a class wich defines the property "DocBase" - I have a dtml document called "DocTest1" in folder "Docs" - I set the "DocBase" to "Docs.DocTest1" Now, I need to call the contents of the document pointed by "DocBase" from a method. No hardcoding besides the name of the class and the name of the property... Several aproaches have been tried, with no luck :( Can anyone help on this eval() ---- Carlos Neves cneves(a)ruido-visual.pt

product creation woes..

sorry for asking the list again, but i got no answers earlier, and i really need assistance on this one... How can i make a product include std_header and _footer when called ?? Tweaking JOhanc's IEmethod, i managed to return them from a redefined __call__ function, but this only works if standard_html_header doesn't try to call other methods.. If standard_html_header refers to other methods, i get name-errors, as if the methods didn't exist... what am i missing ? -- Geir Bækholt Hansen web-developer/designer geirh(a)funcom.com http://www.funcom.com def __call__(self, client=None, REQUEST={}, RESPONSE=None, **kw): """Render the document given a client object, REQUEST mapping, Response, and key word arguments.""" kw['document_id'] =self.id kw['document_title']=self.title if hasattr(self, 'aq_explicit'): bself=self.aq_explicit else: bself=self if client is None: # Called as subtemplate, so don't need error propigation! r=apply(HTML.__call__, (self, bself, REQUEST), kw) if RESPONSE is None: return r return decapitate(r, RESPONSE) r=apply(HTML.__call__, (self, (client, bself), REQUEST), kw) if type(r) is not type(''): return r if RESPONSE is None: return r hh=RESPONSE.headers.has_key if not (hh('content-type') or hh('Content-Type')): if self.__dict__.has_key('content_type'): c=self.content_type else: c, e=guess_content_type(self.__name__, r) RESPONSE.setHeader('Content-Type', c) std_html_header= apply(HTML.__call__, (self.standard_html_header, bself, REQUEST), kw) std_html_footer= apply(HTML.__call__, (self.standard_html_footer, bself, REQUEST), kw) out = std_html_header + r + std_html_footer return out

The Mysterious Key Error and Unrelated Searc Result Bug
by Michel Pelletier 05 Apr '00

05 Apr '00

Wow, what a mystery, you ready for this one? In lib/python/SearchIndex/Lexicon.py the set method of the Lexicon class, change: else: self._lexicon[intern(word)] = self.counter self.counter = self.counter + 1 return self.counter to else: self.counter = self.counter + 1 self._lexicon[intern(word)] = self.counter return self.counter <groans from the audience> Yes, simple programmer error folks. Funny thing is, someone pointed this out to me months ago and it's been fixed in the CVS the whole time, I just never put two and two together on the key error. So good news is CVS users are vaccinated against this bug! And yes, the rest of you have suffered senselessly this whole time. It was a bugger to track down though since when new documents are defined, new words come in groups (and all at first), so that their integers that they map to are close enough to each other to make the result *look* valid, it was only after a lot of unindexing and reindexing did the false word ids drift apart far enough for sporadic 'key' errors to pop up depending what search you did. Unfortunatly patching your 2.1 is more elaborate than just switching those two lines, you have to repair the damaged lexicon. Bad thing is there is no part of the Lexicon interface that lets you clear it. So you have to add that. This involves adding one method and patching another. First, make the first change above, and *in that same file* add this method to the Lexicon class: def clear(self): self._lexicon = OIBTree() Then, in lib/python/SearchIndex/UnTextIndex.py in the UnTextIndex class in the clear() method, add a call to clear in that method, like this:: def clear(self): self._lexicon.clear() self._index = IOBTree() self._unindex = IOBTree() Now update your catalog. You'll get a brand new spanking catalog that will NEVER key error on you again. If you don't know python and you don't know what you're doing, don't do this. Yes I'll release a patch for 2.1.6 and the fix is allready in the CVS. I need some confirmation on the fix first. There are at least a few people out there who won't be driven crazy by this bug anymore. Kudos go to Darran Edmundson for reproducing the bug in one step for me. Someone else made the connection that this also causes the Mysterious Unrelated Search Result bug but I can't open my mailbox right now to who to give that credit. -Michel

Problem with programmatic copy and paste
by Richard Taylor 04 Apr '00

04 Apr '00

We are trying to copy the contents of one folder into another using DTML. The code below produces the following exception: 'One or more items referred to in the clipboard data was not found. The item may have been moved or deleted after you copied it.' <dtml-let clip="manage_copyObjects(objectIds())"> <dtml-with Folder> <dtml-with "_.getitem(REQUEST['id'])"> <dtml-call "manage_pasteObjects(clip)"> </dtml-with> </dtml-with> </dtml-let> This works (mostly) if the getitem call is removed, and the objects are pasted into 'Folder' - which is an instance of a ZClass, which subclasses folder. I have seen a similar question to this in the archives of this list but I have not found an answer. Can anyone help?

I second this. >1. Is MessageDialog available to DTML Methods, and I have just not >found the trick? I have asked the same thing some time ago. >2. Would it be a lot of trouble to make it available? Methinks it's just a matter of importing it into globals... Can't think of any security issues either. Having MessageDialog available is useful for anyone trying to capture even a tiny part of the management interface Rik
