AttributeError: LazyMap instance has no attribute '_product'

I have a Zope 2.8.8 for which I've developed a product that creates an object called Collection that is defined like this:: class Collection(BTreeFolder2, CatalogAware): implements(ICollection) meta_type = COLLECTION_METATYPE def __init__(self, id, **other_stuff): apply(BTreeFolder2.__init__, (self, id), {}) # set other_stuff When in the ZMI, if I try to create an object (eg. Image) using the dropdown I get 404 with: Cannot locate object at: http://localhost:8080/Site/collectionA/manage_addProduct/OFSP If I try to do it in code like this:: def _uploadPhoto(self, file): adder = self.manage_addProduct['Photo'].manage_addPhoto adder('photo', '', file, **photo_settings) Then I get this error:: ... File "/home/peterbe/zope/zope288/Products/Mest/ProductPhotoBase.py", line 122, in uploadPhoto self._addProductPhoto(photo_id, unicodify(comment).strip(), photofile) File "/home/peterbe/zope/zope288/Products/Mest/ProductPhotoBase.py", line 130, in _addProductPhoto photo_adder = self.manage_addProduct['Photo'].manage_addPhoto File "/home/peterbe/zope/zope288/lib/python/App/FactoryDispatcher.py", line 26, in __getitem__ return self.__bobo_traverse__(None, name) File "/home/peterbe/zope/zope288/lib/python/App/FactoryDispatcher.py", line 29, in __bobo_traverse__ product=self.aq_acquire('_getProducts')()._product(name) AttributeError: LazyMap instance has no attribute '_product' Any idea anyone? PS. I've enpseudo coded the code a bit to explain the problem clearer. -- Peter Bengtsson, work www.fry-it.com home www.peterbe.com hobby www.issuetrackerproduct.com

Has anyone generated barcodes output within DTML?

Hi, It is a simple question, has anyone generated barcodes output within DTML? I am just starting to reseach this and I know there are different formats. I tried googling but I did not find this type of integration. My customer prints out a shipping manifest and work like to add the barcode on this paper output. Thanks in advance, Larry

zope migration (plone related)
by chris h 05 Dec '06

05 Dec '06

Greets: Ive been handed an interesting challenge. A debian woody install inclusive of zope and plone died an unruley death due to hardware failure. All that remains is a backup of the data.fs Now its easy enough to reinstall woody and get everything up and running. However when I looked at the installed version of zope, python, cmf and plone (this is essentially a plone site for a dot org) they are extremely dated but at least are consistant with the version of zope which 2.5.1 Given that this collection is so old, Im wondering how difficult of a task it is to move this collection to more recent version of the same. From by basic and preliminary reading it does not look good as everything must be done incrementally to move the collection to the latest release of plone and associated dependencies. So I started thinking about the ZODB. Once restarted on a fresh woody install, and zope 2.5.1 there must be a way to extract only the user data from the ZODB or from plone itself (the later being very easy to do) Secondly once I have the user data there must be a simpler way to migrate this data to a more current release of zope/plone then in incremental stages as described in a few docs that I read. I dont mind doing the necessary homework but I was wondering if my understanding of the process is correct, am I missing something or are there short cuts that I have not reviewed or considered. Thanks for any references or advise sent this way. Best regards /ch

2nd edition of Zope 3 book available!
by Philipp von Weitershausen 02 Dec '06

02 Dec '06

I'm proud to announce that -- as the first Zope book ever -- my book titled "Web Component Development with Zope 3" has been released as a second edition and is now available from online and local bookstores. Like the first edition, the new book is targeted at all web developers who want to get into Zope 3 or learn more about Zope 3 and Zope 3 technology than they already know. It's accompanied by an extensive example application that's extended throughout the book. *Unlike* the first edition, the second edition is... - up-to-date. The book covers the latest Zope 3 release, Zope 3.3, which has only been released recently. All chapters, all examples, and the appendices have been revised to match the most current Zope 3 codebase. - bigger. Five (!) new chapters, all describing new features in Zope, have been added, many others were extended notably. In total, the book is more than 80 pages thicker than the old one -- at the same price as the old one. - better. With the second edition, the book has been completely revamped. My excellent reviewers from the Zope and Plone community have done a tremendous good job at improving the book's language and technical details. I also improved the didactics in various places. - for you! No matter if you're a Zope 3 developer or just starting to get into Zope 3, I suggest you keep the book under your pillow. Even as a Zope 2 or Plone developer, you'd be surprised how much Zope 3 technology you can now use in Zope 2 -- and this book tells you how! This makes it a must-buy especially for Plone developers as Plone 3.0 is using Zope 3 components for all new development. Find out more at http://worldcookery.com.

RE: [Zope] Zope newbie.... unicode problem

How do I get my hands on the template that has the >embedded Unicode characters? Usually, it is not the template itself. As the template contains text, it should (in principle) be unicode -- but Zope is still not that far. There are patches around to change this state and Zope 2.10 might support unicode templates (but I am unsure). Thus, usually, the template is not unicode and some dynamic parts (included via "tal:content|replace|attributes") are unicode. To analyse those problems (I have set Python's default encoding to my site encoding such that I do no longer see such problems) I would reproduce the problem in an interactive Python interpreter ("bin/zopectl debug" under *nix -- there are also solution for Windows, but you need to search for them yourself) and use "pdb.pm()" to find out all relevant details. -- Dieter
