Hi, I am reading the chapter about ZPT (2.5, Chapter 5) and trying this table in a file named 'index_html': <table border="1" cellpadding="5" cellspacing="0"> <tbody> <tr> <td class="header">Name</td> <td class="header">Type</td> <td class="header">Size</td> <td class="header">Last Modified</td> </tr> <tr tal:repeat="item container/files"> <td><a href="Sample.tgz" class="filename" tal:attributes="href item/getId" tal:content="item/getId">Sample.tgz</a></td> <td tal:content="item/getContentType">application/x-gzip-compressed</td> <td tal:content="item/getSize">22 K</td> <td tal:content="item/bobobase_modification_time">2001/09/17</td> </tr> </tbody> </table> And this python script named 'files': return container.objectValues('File') This is the result when I test it: <table border="1" cellpadding="5" cellspacing="0"> <tbody> <tr> <td class="header">Name</td> <td class="header">Type</td> <td class="header">Size</td> <td class="header">Last Modified</td> </tr> </tbody> </table> So, actually, the tal:repeat table row has disappeared for some reason. But there are folders, page templates, python scripts etc. residing in it.. What can be wrong? --------------------------------------------------------------------------- "When a man sits with a pretty girl for an hour, it seems like a minute.

Adding a zcatalog in 2.6
by Luton, Alex 11 Nov '02

11 Nov '02

Hi, I have a problem adding a catalog in zope 2.6 and above. When I go to add a new catalog in 2.5, I get a combobox to select the vocabulary, or zope creates one for me, as it specifies in the docs. If I try the same in 2.6 the combobox is missing, so I'm unable to create a working catalog anymore. I can't believe something this obvious is a bug, but I can't find any notes referring to such a change. I'm still quite new to zope, so apologies if I'm missing something here.

newbie portability question
by Scott 10 Nov '02

10 Nov '02

I'm new to Zope and have a newbie-worthy question about portability. If I develop a site with a mysql back end on my own box using the Z-server and then upload it to an ISP with a run-of-the-mill apache configuration, is it going to work without any extraordinary modifications? Thanks, SW

by Sebastian Queißer 10 Nov '02

Hi! How can I load the return of a function in a frame wich already exists and should only be updated similar to Zope's menu frame, when you delete an Object? Another questions is, if there's someone who had have problems with zope 2.6 and python 2.2. I get a warning, but I can't find any problems. Thanks Sebastian

zclass propertysheets
by Danny Morgan 10 Nov '02

10 Nov '02

OK, I've upgraded my Zope to 2.6 and it looks like the same error is occurring... Problem redescription: I am trying to create a simple zclass for storing and presenting information about individuals. Within a product 'sgNiceStreams' is the zclass 'sgPerson_zclass'. sgPerson has a propertysheet 'contactInfo' and a python script 'getInfo'. The script has only one line: return(context.propertysheets.common.contactInfo.getProperty('email')) which generates the following error and traceback: *============== AttributeError* Traceback (innermost last): Module ZPublisher.Publish, line 98, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 39, in call_object Module Shared.DC.Scripts.Bindings, line 252, in __call__ Module Shared.DC.Scripts.Bindings, line 283, in _bindAndExec Module Products.PythonScripts.PythonScript, line 315, in _exec Module Script (Python), line 1, in test - <PythonScript at /Control_Panel/Products/sgNiceStreams/sgPerson_zclass/propertysheets/methods/getInfo> - Line 1 Module OFS.PropertySheets, line 164, in getProperty Module ZClasses.Property, line 66, in v_self AttributeError: _zclass_ =============== For whatever reason, some propertysheet information is accessible. For example, when 'getProperty' is changed to 'propertyMap', a mapping is returned. code: return(context.propertysheets.common.contactInfo.propertyMap()) output: ({'id': 'fullName', 'type': 'string', 'meta': {}}, {'id': 'email', 'type': 'string', 'meta': {}}, {'id': 'telephone', 'type': 'string', 'meta': {}}) What is this mystery that I have spent much time on with little progress?

Re: user roles & authentication
by Paul Tiemann 10 Nov '02

10 Nov '02

I had the same experience, and after researching it a little, I found that if Zope is asked to perform an action (render a dtml method, call a python script, etc) and that action can be done by the 'Anonymous' role, then Zope doesn't even bother to look at the user's credentials, because it knows that the action is already allowed, no matter what other roles the user has. In those cases, I believe Zope performs the action, passing in a generic anonymous user instead of passing in the actual credentials. That caused trouble for me, when I wanted to call the getUser method and it was giving me the Anonymous user. BUT... If I remember right, you can get the user explicitly by using the 'AUTHENTICATED_USER' of your REQUEST. Here's a little bit of my code that I think might work for what you're asking. <dtml-call "REQUEST.set('roles',['Anonymous',]) <dtml-if AUTHENTICATED_USER> <dtml-call "REQUEST.set('roles',AUTHENTICATED_USER.getRoles())"> </dtml-if> This works for me, but while I'm only trying to be helpful, I might be both misunderstanding your needs, as well as feeding you false information, because I'm only as experienced in this part of Zope to get my own stuff working to my liking. I hope it helps, but If I'm wrong, somebody please correct me... :Paul > the problem is this: if one authenticates at a location > deeper than their user account, authorization should > apply up to the level of the account. it does - any > method requiring authorization is allowed to run between > the point of login and the user account - but when I test > with *any* of these routines between the point of login > and the user account it shows only 'Anonymous' - not the > expected roles. > > user.getRoles() > _.SecurityGetUser().getRoles() > user.has_role( roleName ) > > visiting /manage or any other objects which require > authorization works between the user account and the > point of login - in fact, after rendering an object > which would prompt for authorization if the only role > were *really* Anonymous the roles for that object and > ones it contains are fixed and show the expected > results with getRoles() and has_role(). > > this problem occurred with ZOPE 2.5.0 or 2.5.1, > and IE 5.5 or NN 7.0

variables in path expressions
by Mark Gibson 10 Nov '02

10 Nov '02

For your consideration: <span tal:omit-tag="" tal:repeat="thepage python:['pageA','pageB']"> <span tal:condition="nocall:here/thepage | nothing" tal:content="structure here/thepage"></span> </span> Basicaly, I want to test if 'pageA' exists, and if so, render it. I'd like to do something like tal:condition="nocall:here/$thepage | nothing", but this doesn't seem to work. Any ideas of how to do this? Thanks, Mark
