initlevel at initialization of product with aq_parent
by Nico de Boer 19 Jul '02

19 Jul '02

Hi all, I'm working on a product that renders treemenu's for websites. Now I have to get an initlevel as starting point for my menu. But the function getInitLevel doesn't work in the __init__ method, because acquisition doesn't work here. Following Casey's example at www.zopelabs.com/cookbook/995468614 I got to the following: def manage_addSiteNav(self, id, title=''): """Add a SiteNav to a folder.""" self._setObject(id, SiteNav(id, title, self.getId(), self)) if self.REQUEST is not None: return self.manage_main(self, self.REQUEST) def __init__(self, acquiredObjectName, container, id, title='', initlevel= 0): """initialise a new instance of SiteNav""" self = self.__of__(container) # Create an acquisition wrapper acquiredObject = getattr(self, acquiredObjectName) # Acquire the object self.id = id self.title = title self.initlevel = self.getInitLevel() def getInitLevel(self): """returns the initlevel""" initlevel = 0 parent = self while 1: if hasattr(parent,'aq_parent'): parent=parent.aq_parent initlevel = initlevel + 1 else: break return initlevel - 1 But what is acquiredObjectName in this context?

[ANN] ZWeather 0.2
by Jerome Alet 19 Jul '02

19 Jul '02

Hi, I'm proud to announce ZWeather v0.2 (which now works correctly) ZWeather is a Zope Weather applet available under the GNU GPL. Just add a ZWeather instance for each location you want to get the weather, fill in the four letter Metar location code (find one near your location in the file Locations), and that's it. Weather info is cached for 15 minutes, unless you modify the location code. By default only a subpart of the available weather info is displayed, but much more methods are available, read the source to learn more. To learn more about it, see an online demo, or download it, please go to: http://www.librelogiciel.com/software/ NB : You'll also need the pymetar v0.2 module from Tobias Klausmann and myself, available from : http://unattached.i-no.de/english/linux.php bye, Jerome Alet

Disappearing manage_options Tab
by Barry Berenberg 19 Jul '02

19 Jul '02

I'm trying to create my first Python product in Zope, and I'm running into a strange problem. Basically I have two manage_options tabs (Edit and View). The Edit tab is a simple form to change the title property (I'm starting out very simple). The problem is that the Edit tab disappears after I submit the changes, and then reappears if I go back to folder the object is contained in and select the object again. To eliminate newbie mistakes as the cause of the problem, I uploaded the Addressit Product from the Zope Bible (the earliest version from Chapter 7, again to keep it simple). The problem occurs with that product, too. I'm running Zope 2.5.1 with Python 2.1.3 on Windows 2000 (binary distribution). I also have a Mac (OS X 10.1.5) with the same versions of Zope and Python, and both the Addressit Product and my own product work normally there (the Edit tab doesn't disappear). So I suspect some problem with the Windows binary distribution. Has anyone else seen this problem? Should I try getting a different distribution? Or is it safe for me to ignore the problem? Thanks, Barry Berenberg mailto:berenberg@alum.mit.edu

LocalFS and <dtml-tree>
by Aseem Mohanty 19 Jul '02

19 Jul '02

Hi , I have a LocalFS instance that gives access to a folder on my disk. Now I would like to display the contents of any desired folder in the tree style on a page. The code that I have is: <dtml-let tree_root="ex_files_storage[REQUEST.folder]"> <dtml-tree Name=tree_root> <dtml-var getId> </dtml-tree> </dtml-let> This unfortunately does not display anything, just a blank page. I also tried the <dtml-tree> tag to be like this: <dtml-tree Name=tree_root branches="fileValues"> that kind of works in that I only get list of all folders in the "REQUEST.folder" directory without the + signs that allow you to expand and see if the folder has any sub-folders, even if they exist... just a list of ids of folders in the requested folder the reason i tried it the former way first is that LocalFS has the "tpValues" function defined, so I asssumed everything would be great. What am I doing wrong here?? How can I get a tree view of the contents of the folder in LocalFS?? Finally will the dtml-tree view show individual files in the folders or do I have to specify the leaves parameter and write my own stuff to show that??

LocalFS busted on Zope 2.5.1?? - NOPE!
by Tony McDonald 19 Jul '02

19 Jul '02

Hi all, Just a heads-up. It seems LocalFS is broken under 2.5.1. Creating a new instance works fine, but then trying to view the instance leads to the following; Error Type: TypeError Error Value: filtered_meta_types() takes exactly 1 argument (2 given) Traceback is: Traceback (innermost last): File /home/zope/Zope-2.5.1-src/lib/python/ZPublisher/Publish.py, line 150, in publish_module File /home/zope/Zope-2.5.1-src/lib/python/ZPublisher/Publish.py, line 114, in publish File /home/zope/Zope-2.5.1-src/lib/python/Zope/__init__.py, line 159, in zpublisher_exception_hook (Object: AAA) File /home/zope/Zope-2.5.1-src/lib/python/ZPublisher/Publish.py, line 98, in publish File /home/zope/Zope-2.5.1-src/lib/python/ZPublisher/mapply.py, line 88, in mapply (Object: main) File /home/zope/Zope-2.5.1-src/lib/python/ZPublisher/Publish.py, line 39, in call_object (Object: main) File /home/zope/Zope-2.5.1-src/lib/python/App/special_dtml.py, line 61, in __call__ (Object: main) File /home/zope/Zope-2.5.1-src/lib/python/DocumentTemplate/DT_String.py, line 473, in __call__ (Object: main) File /home/zope/Zope-2.5.1-src/lib/python/DocumentTemplate/DT_Util.py, line 159, in eval (Object: filtered_meta_types(AUTHENTICATED_USER)) (Info: filtered_meta_types) File <string>, line 0, in ? TypeError: (see above) Is this just an artifact of my zope installation, or is this generic to LocalFS on 2.5.1? Anyone got any clues? *voice from the peanut gallery* "I do" I figured this out before I hit send, so here's the fix. Edit main.dtml in LocalFS and remove all references to AUTHENTICATED_USER. Eg <dtml-in "filtered_meta_types(AUTHENTICATED_USER)" mapping sort=name> Goes to <dtml-in filtered_meta_types mapping sort=name> There's a few other lines in there with AUTHENTICATED_USER in main.dtml, so make sure you get all of them... LocalFS is quite an old product, but it still keeps rolling along :) Tone. -- Dr Tony McDonald, Assistant Director, FMCC, http://www.fmcc.org.uk/ The Medical School, Newcastle University Tel: +44 191 243 6140 A Zope list for UK HE/FE http://www.fmcc.org.uk/mailman/listinfo/zope

simple z-class problem
by Ben Avery 19 Jul '02

19 Jul '02

Hi, I'm having intermittent problems with the simplest z-class within a new product, through the ZMI. I'm going through the stages of 1) I create a new product, CalendarEvent. 2) inside Test, I create a z-class, id: CalendarEvent. 3) inside this, I add some property sheet with some properties through the properties tab. 4) finally, I change the default view to propertysheets/Prop/manage from the dropdown list. Now when I try to create an instance of it in a development folder, I get the constructor form, but then a NameError: *Error Type: NameError* *Error Value: global name 'CalendarEvent' is not defined* trace below: Traceback (innermost last): File /export/home/Zope-2.5.1/lib/python/ZPublisher/Publish.py, line 150, in publish_module File /export/home/Zope-2.5.1/lib/python/ZPublisher/Publish.py, line 114, in publish File /export/home/Zope-2.5.1/lib/python/Zope/__init__.py, line 159, in zpublisher_exception_hook (Object: CalendarEvent_factory) File /export/home/Zope-2.5.1/lib/python/ZPublisher/Publish.py, line 98, in publish File /export/home/Zope-2.5.1/lib/python/ZPublisher/mapply.py, line 88, in mapply (Object: CalendarEvent_add) File /export/home/Zope-2.5.1/lib/python/ZPublisher/Publish.py, line 39, in call_object (Object: CalendarEvent_add) File /export/home/Zope-2.5.1/lib/python/OFS/DTMLMethod.py, line 127, in __call__ (Object: CalendarEvent_add) File /export/home/Zope-2.5.1/lib/python/DocumentTemplate/DT_String.py, line 473, in __call__ (Object: CalendarEvent_add) File /export/home/Zope-2.5.1/lib/python/DocumentTemplate/DT_With.py, line 61, in render (Object: CalendarEvent.createInObjectManager(REQUEST['id'], REQUEST)) File /export/home/Zope-2.5.1/lib/python/DocumentTemplate/DT_Util.py, line 159, in eval (Object: CalendarEvent.createInObjectManager(REQUEST['id'], REQUEST)) (Info: REQUEST) File <string>, line 2, in f NameError: (see above) I have done this exact procedure before, with success. Now it doesn't work. I've rebooted the zope server. I'm using Zope 2.5.1, Python 2.1.3 on Solaris 2.7. Has anyone else seen this, or can anyone tell me what I'm doing wrong?
