student folders
by Bill Kerr 19 Apr '02

19 Apr '02

I'm a school teacher and want to set up a folder structure of users in Zope consisting of school class names, such as 12ITSAS, and then individual folders at the next level down for each individual student, Student1, Student2, Student3 etc. I'm inexperienced with Zope but do have some background in programming. I would like the students to have read only and copy rights at the 12ITSAS level folder and manager rights in their individual, Student1, Student2 folders. In that way I can provide them with resources within the 12ITSAS folder that they can't change at that level but which they can copy and change at the level of their folders. I can't see how to do that efficiently using the Zope security model. When I provide students with Manager rights at the level of their individual folders (Student1, Student2 etc) then they can't access the 12ITSAS folder because that is at a higher level. And of course if I give them Manager rights at the 12ITSAS folder level then they can modify what I supply them and invade each others folders. Any assistance would be much appreciated. - Bill Kerr Woodville High School South Australia

Xron bug?
by Peter Bengtsson 19 Apr '02

19 Apr '02

Hello, I use Xron-0-0-10.tgz on Zope 2.5.0 Linux and I have created a Xron DTML Method that only works when I click the View tab. When I click the Trigger tab I get this error message: Traceback (most recent call last): File "/home/petbe/zope/zope250/lib/python/Products/Xron/XronDTMLMethod.py", line 141, in trigger REQUEST=REQUEST, RESPONSE=RESPONSE, kw=kw) File "/home/petbe/zope/Zope-2.5.0-linux2-x86/lib/python/OFS/DTMLMethod.py", line 136, in __call__ del self.__dict__['validate'] KeyError: validate I have had other successful Xron DTML Methods in this site. Here is the content of the Xron DTML Method:: Content-type: text/html <b>Arkivera:</b> <dtml-var "doArchiveEvents(['gskolan','doc',events_obj_container], ['gskolan','noidx','handelse_arkiv'])"> Best regards, Peter

Use the sour..... contribute to the ideas of how to improve documentation and information about Zope
by Heimo Laukkanen 19 Apr '02

19 Apr '02

Hi all again, from the last posts I have been really busy working, but now I spent a small event of time writing some content to the wikis about the documenttation. I will continue but please contribute and let's discuss what kind of things we would need to work on as a community. Log into the zope.org and then go to page: http://www.zope.org/Wikis/Docs/DocumentationBrainstorm Besides the raw ideas, you could also try to write stories about the perfect world from the perspective of different users. This is a great way to actually get information about what would the experience of the user learning to use Zope would need to be: http://www.zope.org/Wikis/Docs/UtopiaVision It is in the beginning stage, but please - contribute. And please also note the information that is already present: http://www.zope.org/Wikis/Docs/FrontPage -huima

Problem in the code, XUFTOOLS
by Heimo Laukkanen 19 Apr '02

19 Apr '02

I made just a quick hack to the code. In setMemberProperties I changes the saved value to be a string. I am not sure if this will cause any problems, but I doubt it. I also noticed a funny thing in your code compared to the MemberData code. XUFTools puts the full mapping into the properties, while MemberDataTool only puts those properties that are really defined in the tool. In the concrete use this means that with XUFTool now even information about the request gets stored in the member properties. -huima def setMemberProperties(self, mapping): '''Sets the properties of the member. ''' #just pass the properties over to acl_users.currentPropSource memberdatatool = self.getTool() propsource = memberdatatool.acl_users.currentPropSource username = self.getUserName() for key in mapping.keys(): propsource.setUserProperty(key=key, ---->here value=str(mapping[key]), username=username) #let the parent class take care of self._members MemberData.setMemberProperties(self, mapping)

How to suppress aquisition of an attribute in a Catalog
by Jens Wolk 19 Apr '02

19 Apr '02

Hi everybody, I have two custom classes: a folderish myFolder class and contentish myContent class. Objects of the myFolder class have the attribute folderAttribute. The objects of the myContent class do not have this attribute. myContent objects typically reside inside a myFolder object. For example, I have an object 'AFolder' of the myFolder class in which resides the object 'AContent' of the myContent class. AFolder.folderAttribute is 'it is me!'. In a catalog I created a field index 'folderAttribute'. Now, if I search the catalog for objects with folderAttribute = 'it is me!', the result set contains the AContent object, too, because it aquires the attribute from the containing AFolder object. Is there a way to suppress this behavior (apart from defining a 'dummy' attribute for myContent class or iterating through the result set and excluding all non-myFolder objects)? Thank you very much.

developing with zope, vim, cvs and cadaver
by dman 19 Apr '02

19 Apr '02

I've just recently learned zope, and it is great. Far better than J2EE, and faster to work with than plain old CGI. I've got a few difficulties, though. I use vim as my primary editor, and I would like to use cvs to backup my work. I can do this with ZPT and Script objects, but it is rather cumbersome to repeatedly upload the files through the web interface. In addition, I can't do that with ZSQL methods. As I was RTFMing, I discovered that I should be able to use cadaver to move files/objects between the local filesystem (where I use vim and cvs to work with them) and the ZODB. I can access ZPT and Script sources with cadaver, but I can't seem to upload changes with it. I also can't access or update ZSQL methods. Am I missing something really obvious, or is it just very difficult to develop a zope site using some traditional tools? TIA, -D PS. ftp isn't a viable option for this site -- Consider what God has done: Who can straighten what He has made crooked? Ecclesiastes 7:13

Anonymous ftp
by Chetan Kumar 19 Apr '02

19 Apr '02

Hi all How can anonymous ftp be disabled on Zope ? ftp on port 8021 (medusa) does not need any login/password !!!! It just lets anybody in. This will be noticed by any automatic security checking tool (I used nessus). However, it does not allow any listing/getting/putting of files. TIA Chetan

XUF Tools - unpickable error, anyone else having same?
by Heimo Laukkanen 19 Apr '02

19 Apr '02

Hi, My config: Zope 2.5.0 CMF 1.3 beta exUserFolder 10.8 XUF 0.0.91 ( version.txt btw says it is 0.90, fix that ,-) ) When I try to create new users in the CMF I get unpickable error with traceback below. The same happens on different propertysources. Propertysources themselves seem to work otherwise ok, as does the exUserFolder and CMF. Any ideas? -huima File /root/zopenew/Zope-2.5.0-linux2-x86/lib/python/ZPublisher/Publish.py, line 150, in publish_module File /root/zopenew/zope/Products/Localizer/__init__.py, line 65, in new_publish File /root/zopenew/Zope-2.5.0-linux2-x86/lib/python/ZPublisher/Publish.py, line 114, in publish File /root/zopenew/Zope-2.5.0-linux2-x86/lib/python/Zope/__init__.py, line 158, in zpublisher_exception_hook (Object: Intranet) File /root/zopenew/Zope-2.5.0-linux2-x86/lib/python/ZPublisher/Publish.py, line 102, in publish File /root/zopenew/Zope-2.5.0-linux2-x86/lib/python/Zope/__init__.py, line 172, in commit File /root/zopenew/Zope-2.5.0-linux2-x86/lib/python/ZODB/Transaction.py, line 233, in commit File /root/zopenew/Zope-2.5.0-linux2-x86/lib/python/ZODB/Connection.py, line 345, in commit (Info: (('Products.exUserFolder.zodbPropSource.zodbPropSource', 'zodbPropSource'), '\x00\x00\x00\x00\x00\x00N\xe3', '')) UnpickleableError: (see above)

tree widget question
by Dennis Allison 19 Apr '02

19 Apr '02

Anyone had experience using the tree widget to render mixed structures? I have a layout something like this -- >>>>>>> Folder Folder XML Folder XML Folder XML Folder XML Folder Folder Folder and so forth. I'd like to point the tree widget at the top level folder and have it render a set of stuff. When an XML (ParsedXML) folder is encountered, the branches method has to be different. (That was the effort of the day, getting tpValues to ignore implementation nodes. I did it by brain surgery on the Package source--a decision that will certainly come back to haunt me.) Presumably, the way to make it work is to use branches-expr and toggle between a folderish objectValues and a ParsedXML-ish tpValues. Anyone had any experience doing this? -d
