Have you "CMF" ("CMFCore" would be sufficient) installed? Which version? Use 1.3.3 or 1.4.2. -- Dieter

How to pass arbitrary objects to a ZPT from Script(Python)
by Martin Diers 08 Nov '03

08 Nov '03

I am programming a purchase order system, using MySQL as a backend. I am new to Zope, but have much experience in RDBMS, some ASP.NET, etc. Currently firmly entrenched in Linux. I am attempting to develop a standard methodology for accessing my databases. I have created ZSQL methods for searching/insert/delete/update. I am using ZPT's. I have a single Script(Python) which processes data requests using an if,elif tree. The idea is simple: all data submit buttons are named btnDataCommand. The value of the button determines which action the script performs. Record ID's are passed via hidden form fields. I would ideally like to have this single python script perform all ZSQL method calls. To me it just makes sense to have all your update logic in a single script. Right now I perform inserts, deletes, and updates directly in this script. However, when it comes to fetching data and displaying it in a ZPT, I have hit a brick wall. Right now I am passing the ZPT a record ID, and having the ZPT call the ZSQL method to retrieve its own data. Example: elif datacommand == "Edit": vendorID = request.get("vendor_id") page = context.addeditVendor_html(record=vendorID) return page I would prefer something like this: elif datacommand == "Edit": vendorID = request.get("vendor_id") results = searchVendors_sql(VendID=vendorID) page = context.addeditVendor_html(dataset=results) return page My problem is this: How can I, from a python script, pass a result set which has been returned from a ZSQL method, on to a ZPT, so that I do not have to call the ZSQL method within the ZPT file which is displaying the data? I tried passing the result set as an option to the ZPT, but it shows up empty in the ZPT. The options container is not well documented, but apparently it is a simple tuple, and will not allow you to put an arbitrary object in the "value" side.

Connect to rdbms from a product
by mlong＠datalong.com 08 Nov '03

Hi, Are there any FAQ's, recipes, etc. that explain how to access a database from within a product. I am on a win2k os connecting to SQL2K. I tried looking at the source for ZODBCDA, exUserFolder and googling but have come away confused. I know that ZODBCDA is not recommended but I am building a prototype that if works will allow some dollars to be spent for a more robust solution. If someone could point me in the right direction I would appreciate it. Thanks, Mike

GRUF (Group User Folder) and exUserFolder ...
by Jason LeMonier 08 Nov '03

08 Nov '03

Hey, I'm trying to get GRUF 2.0 Beta and an exUserFolder. GRUF 2 supports multiple acl_users objects!! awesome! acl_users (gruf) Groups acl_users (normal/plone) Users acl_users (normal) Users01 acl_users (exUserFolder) Couple Problems: 1) "Normal" or simple Plone/Zope acl_users work fine and authenticate. External Users do not authenticate. (users are listed, and the same ex acl_users by itself works. 2) Recursion while trying to list users -- documented in readme: " To avoid this, just create a getUserNames() object (according to SimpleUserFolder specification) in the folder where you put your SimpleUserFolder in (ie. one of 'Users' or 'Groups' folders)." Well ... I'd love too, but from the ZMI: GRUFUsers at /Plone/acl_users/Users01 only object listed: acl_users But I'm unable to create a python script: "getUserNames" in this directory?? Bad Request -- the id "getUserNames" is invalid -- it is already in use. So ... I'm digging into the products and trying to figure out what function should be added or changed. Any help is always appreciated!! ciao, jason Jason LeMonier Software Engineer Retail Technologies International Office 916.605.7262 Mobile 415.595.0969 Fax 916-914-2132 jlemonier(a)RetailPro.com

RE: [Zope] changing port from 9673 default
by George Perry 08 Nov '03

JCC: For this application (where I have two dozen users who all know and trust each other working behind a well maintained firewall), I like your iptables suggestion better than setting up a proxy web server. I also appreciate Jamie Heilman's effort in taking the time to make sure I was aware of the security/stability issues of using a naked zope server. I tried changing the port to 8080 using /etc/zopectl/zopectlrc (per Jamie's suggestion that I was failing because I was trying to use a privileged port), and this silently failed (I still saw the zope intro page being served on port 9673). I apologize for only searching the last three month's of the list archive before posting. I appreciate your time and patience in responding to and educating me.

It will insist on being given a regular user to actually run as: read doc/SECURITY.txt. Another option is using your OS to do it:: /sbin/iptables -t nat -I PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8080 to get port masquerading from 8080 to 80 (although it won't work on localhost). This is an oft-discussed topic on the list, by the way. --jcc -- "My point and period will be throughly wrought, Or well or ill, as this day's battle's fought."

Dylan: Thanks for the suggestion. I have tried that unsuccessfully, but I was trying to redirect to the privileged port 80 - which Jamie Heilman has told me will not work unless I run Zope as root. This had worked when I had earlier installed the Linux version of Zope linked to at Zope.org. The Debian Zope packager appears to be working to make the Zope server controlled in a fashion similar to the method used by Apache.

Try this: $ locate z2.py Last time I checked, Debian put Zope in /usr/lib/zope Once you've found that, open it up and look for this line: HTTP_PORT=9673 Which you change to: HTTP_PORT=8080 And restart Zope.
