Hi I have say 3 folders with following ids folder1 folder2 folder3 Now I show this list to the user in a comno box. User selects folder which results in displaying of the contents of that folder. Say the select box name is category i.e <select name="category"> now when the user selects one of the category what I do is <p tal:define="category request/form/category"> </p> <table> <tr tal:repeat="item category/objectValues"> <td tal:content="item/id">Id</td> <td tal:content="item/title">Title</td> </tr> </table> It gives me a key error .What should I do to correctly traverse the folder __________________________________ Celebrate Yahoo!'s 10th Birthday!

root folder hangs on Contents in manager iface
by John Hunter 07 Mar '05

07 Mar '05

I have a Zope-2.7.3 installation running on linux. I can no longer access the contents of the root folder in the manager interface using http. I see the left frame which shows acl_users, Control_Panel, etc, and when I click on any of them I see the views you would expect in the right frame, eg the Contents and Undo tabs. But when I click on http://localhost/manage_workspace, my browser hangs (tested on IE under windows XP and Firefox on linux). I can ftp into the root dir and do an ls and see the contents. The attempt to access manage_main just hangs there with a "Waiting for localhost" message in the status bar. I am not running a firewall. I shut down my 2.7.3 install and did clean install of 2.7.4 to a new dir (build notes below) and I got exactly the same problem running 2.7.4 from a clean install! So I thought something may be wrong with my python site-packages dir, which I temporarily hid by renaming it to site-pacakges.hide, but this was no help. Perhaps I have a bad system lib? Any ideas?

firewall and passive ftp
by Michael.Kaplan＠t-online.de 07 Mar '05

07 Mar '05

Hi, I have a problem using Zope-ftp with our firewall. With passive ftp one cannot know wich ports are being used for communication. Port 8021 is open and works. Ftp on the local machine works as well (passive and active). Opening all high ports on the firewall is not an option. Is it possible to specify (for example in zope.conf) which ports are allowed for passive ftp (like PassivePortRange 30000 40000 for other ftp servers), so that we can reconfigure the firewall for these ports? If not, are there any other ways of solving this? Thanks in advance for all help! Michael

I am missing something... (sorry) : to create : tree={'a':{'b':1,'c':2},'d':4} How would I do using OOBTrees ? Is this right ? tree2=OOBTree() tree2.update({'b':1,'c':2}) tree=OOBTree() tree.update({'a':tree2,'d':4}) The problem is that when in a ZPT I access tree (being an attribute of some of my objects), I get Security problems to access tree2.

No fear, they act mostly like mappings themselves ;) Take a look at <zope>/lib/python/BTrees/Interfaces.py to see what you can and cannot do. jens _______________________________________________ Zope maillist - Zope(a)zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev ) ********************************************************************** This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.

Form action with Python script and arguments
by Henk Jansen 07 Mar '05

07 Mar '05

I have two problems when I want for pass <FORM ...> information into a Python Script: 1) Besides passing the FORM data, I also need to pass an extra argument into the Python script that was passed (as <URL>?arg=argval) by the URL. A thing like: <FORM action=my_py_script(arg=<dtml-var argval>) doesn't work. Neither does: <FORM action="my_py_script(arg=<dtml-var argval>") What's the proper syntax for passing extra arguments to a Python script in a FORM action? 2) How do I access the FORM data in a Python script? I've tried "import cgi" but a call to cgi.FieldStorage() was met by a message that I wasn't authorized to make this call ... Thanks, --Henk

I just realized it as I was typing :) It's just that I have never used BTrees, while I have been using PersisentMapping for a while. I will have a try. Thanks.

If I don't misunderstand this completely you're basically trying to emulate a tree by nesting mappings. You should be using a "real" tree instead, maybe a BTrees.OOBTree? jens _______________________________________________ Zope maillist - Zope(a)zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev ) ********************************************************************** This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.

Nested PersistentMappings and security
by Pascal Peregrina 07 Mar '05

07 Mar '05

Hi, Here is my problem : I have a Zope object that defines a PersistentMapping attribute. The PersistentMapping can also have PersistentMapping values for some keys. I mean : MyObject MyObject.containers is a PersistentMapping And MyObject.containers[somekey] can also be a PersistentMapping In a management ZPT of MyObject, I try to loop on the MyObject.containers keys to display key/value pairs. I get : ... Module Products.PageTemplates.ZRPythonExpr, line 47, in __call__ __traceback_info__: container_data['description'] Module Python expression "container_data['description']", line 1, in <expression> Module AccessControl.ZopeGuards, line 71, in guarded_getitem Unauthorized: You are not allowed to access 'description' in this context (container_data is the value - a PersistentMapping - of one of the MyObject.containers keys) My questions are : + how can I remove Security checking on all MyObject.containers values ? + is there a better type of object to use instead of nesting PersistentMappings ? Thanks.

I have recently found a SFTP server product for zope > called SFTPGateway but have been successful in getting it operating yet. you need to connect to your backends directly, I think. at least thats what we do. define a tunnel to your backend server, like $ cat .ssh/config Host host.name.com LocalForward 18021 localhost:8021 LocalForward 18080 localhost:8080 LocalForward 18088 localhost:8088 then ssh to host.name.com, and point your webdav-client to localhost:18088; you can easily test the above setup if you point your browser to http://localhost:18080/ BTW, if your apache is "only" doing the ssl-proxy job, you might want to look into something leaner like pound (http://apsis.ch/pound) which in my opinion is much easier to maintain, and gives you a load-balancer as a bonus. Good luck, Sascha
