What exactly are "sufficient permissions" ? Thanks, Derek Wilson -----Original Message----- From: Dylan Reinhardt [mailto:zope@dylanreinhardt.com] Sent: Friday, October 10, 2003 11:27 AM To: Derek S.

It seems reasonable, by default, that you wouldn't want to allow just *anyone* to examine your user folder. :-) Since you *want* non-default behavior, give this method a proxy role that has sufficient permissions. Once you've got that, you may want to restrict access to this method, granting use of it only to authenticated users, for example. HTH, Dylan

getting a list of users from ACL_USERS
by Derek S. Wilson 10 Oct '03

10 Oct '03

**trying again** I need to get a list of users in ACL_USERS to create a form where people can assign stuff to different users. Here's the code for the display... <SELECT NAME="AssignedTo"> <dtml-in "acl_users.getUserNames()"> <OPTION LABEL="<dtml-var sequence-item>" VALUE="<dtml-var sequence-item>"><dtml-var sequence-item></OPTION> </dtml-in> </SELECT> But when I try it using a regular (non-manager/owner) it says: Error Type: Unauthorized Error Value: You are not allowed to access getUserNames in this context When I use the site manager, it works fine... What could be wrong? What permissions need to be set so that authenticated users can use "getUserNames" in this context? Thanks, Derek Wilson

sorting results by time
by Katie Legere 10 Oct '03

10 Oct '03

I'm pretty new to Zope and am trying to sort results by time. I have a perfectly working <dtml-in> that is going through files and g them in reverse but I would like to filter out ones older than 10 days... I've tried: <dtml-if "bobobase_modification_time < '2003/09/30 15:11:04.697 GMT-4'"> New message posted after '2003/09/30 15:11:04.697 GMT-4'<br> <dtml-else> old message posted before '2003/09/30 15:11:04.697 GMT-4'<br> </dtml-if> But it definately isn't comparing the times properly.

Counting sessions in Zope
by Gitte Wange 10 Oct '03

10 Oct '03

Hello, I have implemented some Session-based login to Zope - works very nice :-) The reason for doing the logins by sessions, is because I hope to then be able to count how many users are logged-in (or how many sessions there are - I know that there can be a delay on the expiration of the sessions). But how do I count the sessions? Is it possible? I have looked at Session Data Manager but it doesn't seem there is a function for this in that object. Where to look ? -- Gitte Wange Technical Manager Email: gitte(a)mmmanager.org Web: http://www.mmmanager.org Tlf: +45 36 46 20 02 Everything is fine except I have about 8,564 questions about how to integrate the client side scripting, server side scripting, and all things in between. -- Joseph Griffin: Zope mailing list, Setting up Zope.

Design around conflict errors
by Jeff Youel 10 Oct '03

10 Oct '03

I've created an object to record some information (datetime, url, username) for each file downloaded from the site for later searching (CMF 1.3.1, Zope 2.6.1). To do this, I have a BTreeFolder with a private ZCatalog and put an new instance of a DownloadRecord object (my own object that just has string members holding the fields to be queried later) into the folder when the file is requested. I'm running into conflict errors; I think because the download record object is added to a single folder so concurrent downloads on different threads are competing trying to modified the folder. Because the downloads will take a while (they're 1-5 MB), the transaction is not committed until the download is complete. With a large download it seems that window for conflicts is large. I've been googling and reading about conflict errors but haven't found a solution yet. I've tried committing the a sub-transaction but that didn't help. I'm thinking of committing the default transaction before sending the file, but I'm not sure of the implications of doing that. Any ideas? Thanks, Jeff

VirtualHostMonster and FTP
by Luke Duff 10 Oct '03

10 Oct '03

I'm able to add mappings in VirtualHostMonster to point *.mysite.com to /Sites/MySite successfully as far as HTTP goes. I'm wondering if there's any way to get it working with FTP. I still have to ftp to mysite.com and change the dir to /Sites/MySite. My mappings are like this: *.mysite.com/Sites/MySite I'm not running zope behind Apache or IIS, just the straight zope server. Thanks, Luke Duff

URL redirection, maintaining arbitrary path?
by Ian Beatty 10 Oct '03

10 Oct '03

Greetings. I'm in the process of porting a website over to Zope/Plone, and find it necessary to do some reorganization of my site's URL structure. In order to break as few old links as possible, I'd like to put in some redirects. I've found information on how to redirect one particular URL, but what I'd like to do is this kind of thing: have *any* request of the form http://my.server.com/x/a/b/... get redirected to http://my.server.com/x/newPiece/a/b/c where the path that comes after "x/" in the original URL (if anything) is preserved at the end of the "new" URL. In other words, I'm mapping an entire tree of my site to a new location. Is this possible? Any suggestions?

Help: terrible problem
by DTE webmaster 10 Oct '03

10 Oct '03

Hi, I had Zope instaled in a machine running SuSE 8.1 Zope 2.6.1 was compiled using Python 2.1 Now, we bought a new server and installed RedHat 9 I've made a tarball from the old server and uncompressed it in the new one. If i run Zope with Python 2.2.2 (bundled with RedHat) i've got two warnings and Zope starts. But the access to the site holds on until timeout. I 've compiled Python 2.1 and i got an error saying there was no _socket.so I've copied it from the old to the new server and then it complained about not finding libssl.so.0.9.6 I've resolved the issue with a symbolic link. Same thing for libcrypto. Well, this time Zope starts without errors, but there again is so slow unitil timeout. What is going on ? Please help. Thank you in advance for your time and patience. Warm regards, Mário Gamito
