Hello, I want to display the content of a site starting from a folder called 'Site' with a tree tag. I want also to render immediately inside the tree the documents with an ID=='PUBLIC_Doc'. In Zope 1.x I have a working dtml method like this:   <b></b>  ##      ##    Unfortunatly for me , with zope 2.1.6 i get an error when I try to render the 'PUBLIC_Doc' document: ..... PUBLIC_Doc !# Error type:AttributeError Error Message: Error Message:__call__ Error TB:Traceback (innermost last): File "/usr/lib/python1.5/site-packages/DocumentTemplate/DT_Try.py", line 221, in render_try_except result = render_blocks(self.section, md) File "/usr/lib/python1.5/site-packages/DocumentTemplate/DT_Util.py", line 335, in eval return eval(code,globals,d) File "", line 0, in ?

Re: [Zope] Why can't I subclass a ZSQLMethod?
by Ivan Raikov 03 Jul '00

What do you mean, you cannot get a view to it? I can change in the management area. I believe ZSQL methods are not supposed to provide the user interface; you use them the way you would use an external method. That means you have to create the form that sends the query parameters to the SQL method, and you have to write the DTML code that obtains the result set, and displays it accordingly. At least that's way I do it; there might be a better way, I don't know. Best, Ivan "Cary O'Brien" <cobrien(a)Radix.Net> writes: > I tried that.

Comments on 2.2 Help System
by Chris Withers 03 Jul '00

03 Jul '00

Apart from the 'Wow! Zope has Help!' comment: The API documentation is very useful. How do we feedback about it? (eg: why is there PropertySheet and PropertySheets?) When will it be complete? How do we submit docs to appear in it? What is the moderation process like? Sadly, the rest of the 'Zope Help' section needs a lot more structure to be useful. At the moment, the names don't even fit in their browser pane :( Perhaps something along the lines of the portal structure on zdp.zope.org would be useful for categorising these documents? If these are the 'help screens' you get when you click the help button, maybe they shouldn't be listed here at all? I have to say, I think the M$ help system on Windows might be a better model: 1. A Contents Page - kindof like the zdp portal listing, or a contents section of a book. 2. An index page - A list of all the documents in the help system, which seems to be largely what the 'contents' tab is now. 3. Search - which needs to be explained better than it is. Can boolean searching be used? Do I need to quote things? How do I search for dtml-in? (Maybe a help screen would be useful ;-) Maybe there should be links to the Contents Page as well as help on your current location from in the management interface? Finally, you should make it clear elsewhere that /HelpSys on your site will go to the Zope help system. Maybe this needs to be blockable, after all, why should www.mysite.com/HelpSys give the Zope help system, when I might want it to be my company's help system for their products? Which suggests that maybe the help system should be a separate product from Zope, running on its own server. For example, take a company which has LOTS of zope servers. The sysadmin would prefer to maintain one up-to-date copy of the Zope docs on a 'documentation server' which has documentation for all the Zope versions in use, rather than wastefully running the same number of documentation servers as there are Zope instances... ...heaven forbid, DC could actually run a master one of these at doc.zope.org which would be the most complete and up to date... Views? cheers, Chris

User Management Styles
by Chris Withers 03 Jul '00

03 Jul '00

Hi, I've noticed two styles for managing users in Zope. 1. Have one User Folder in the root of your Zope instance and then manage what users can do through Local Roles (PTK and Zope.org spring to mind) 2. Have user folders at each level of your content tree. This is as recommended in the ZCMG and otehr older docs. The question is, which method is better? My comments would be: 1 is better if the site is 'managed' by a system such as PTK or uses components such as LoginManager that are non-trivial to setup. 2 is better if you REALLY want to delegate authority for subfolders. The obvious one is Zope ISP's with more than one client per instance of Zope. Please not the 2 currently has serious problems (see the 'Every user should have the Anonymous role everywhere' thread) and I'm sure I remember readign about bugs with Local Roles (btu I expect they've all been fixed by now...)# Comments?

Access object inside a folder
by Sin Hang Kin 03 Jul '00

03 Jul '00

Hi, I have put objects inside a folder tabledef and would like to refer them : <dtml-in "_.getitem('tabledef').objectItems(['DTML Document'])" sort=id mapping> <dtml-var "_['sequence-item']" html_quote> </dtml-in> However, this does not work, But putting the objects in the current folder works without problems: <dtml-in "objectItems(['DTML Document'])" sort=id> <dtml-var "_['sequence-item']" html_quote> </dtml-in> I also try: <dtml-with tabledef> <dtml-in "objectItems(['DTML Document'])" sort=id> <dtml-var "_['sequence-item']"> </dtml-in></dtml-with> and some other combinations, all without success. How can I access the objects (DTML DOCUMENTS) inside a folder? Moreover, I would like to do the following: I have some properties of an object abc which have same name with the object ids in the tabledef folder, I would also lookup the objects' properties : <dtml-in propertyMap mapping> <dtml-with tabledef.id> <dtml-var help> <dtml-var taborder> </dtml-with> </dtml-in> Assume abc have a property address, then there should be a dtmldoc call address in tabledef, which have properties "help" and "tableorder". I would like to retrieve them. Can somebody help me with these? Rgs, Kent Sin --------------------------------- kentsin.weblogs.com kentsin.imeme.net

ZCatalog pointing to wrong object.
by Bart Holthuijsen 03 Jul '00

03 Jul '00

Hi all! I have been having some problems with ZClasses and the Catalog. I made a new Catalogaware External Product, based mostly on the Boring and Photo products. When I add an instance to a folder the Catalog is updated, but doesn't point to the right object. The product inherits from Catalogaware and Objectmanager (and some others). Example: In the folder "test" I add an XML Folder (the product) with name: "fold" and title: "no1". The Catalog shows a new object with name "test" and title: "no1". If I then add an XML Folder to test with name "fold2" and title "no2" the Catalog still only contains one object: test/no2. If I want to delete the objects I get some weird behavior. The first one goes without a problem, it removes the entry from the Catalog. The second gives an error message: "Error Type: ValueError Error Value: Uncatalog of absent id 'Test' " This can probably be explained by the fact that there was only one entry pointing to the Test Folder. Below I'll paste a bit of the XMLFolder.py file: from Products.ZCatalog import ZCatalog from Products.ZCatalog.CatalogAwareness import CatalogAware import OFS.ObjectManager import Acquisition import AccessControl.Role from Globals import HTMLFile # fakes a method from a DTML file from Globals import MessageDialog # provid from Globals import Persistent # makes an object stick in the ZODB manage_addXMLFolderForm = HTMLFile('XMLFolderAdd', globals()) def manage_addXMLFolder(self, id, title='', REQUEST=None): """Add an XMLFolder to a folder.""" self._setObject(id, XMLFolder(id, title)) if REQUEST is not None: return self.manage_main(self, REQUEST) class XMLFolder( CatalogAware, # Self indexing. OFS.ObjectManager.ObjectManager, # A Folderish object. Persistent, # Make us persistent. Yaah! Acquisition.Implicit, # Uh, whatever. AccessControl.Role.RoleManager # Security manager. ): """XMLFolder object. """ meta_type = 'XML Folder' # what do people think they're adding? manage_options = ( # what management options are there? {'label': 'Contents', 'action': 'manage_main'}, {'label': 'View', 'action': ''}, # defaults to index_html {'label': 'Security', 'action': 'manage_access'}, ) __ac_permissions__=( # what permissions make sense for us? ('View management screens', ('manage_tabs','manage_main')), ('Change permissions', ('manage_access',) ), ('Change XML Folders' , ('manage_edit',) ), ('View XML Folders', ('',) ), ) def __init__(self, id, title=''): """initialise a new instance of XMLFolder""" self.id = id self.title = title self.manage_addFolder('test','',0,0) Does anyone know what the problem might be, how I can get the Catalog point to the right object? I'm using Zope 2.1.4 on Windows NT.

ZClass beginners question
by Dierk Hoeppner 03 Jul '00

03 Jul '00

Hi, I want to connect our own proprietary database to zope. I know which features I want because I did an ordinary CGI-application already. I would like to use a ZClass. My question: For connecting to my database do I have to use external functions? The goal is to construct a product like thing that we could easily give away.
