Zope Documentation/Help - a suggestion
by Jon Edwards 17 Jun '01

17 Jun '01

Reading a lot of the recent posts about the need for more documentation, the thought struck me that there's already loadsa resources out there, but people don't know where to find them! So, what if people who have an interest/expertise in a particular area collected together useful links/resources (How-tos, articles, mailinglist posts) in one place, so that people could find them easily? As an example, I created a doc in my CMF Dogbowl Member's section with a list of lots of Windows-related links I've found on my travels. (I don't claim to be an expert, just someone who has collected lots of links! :-) http://cmf.zope.org/Members/joned/winstuff - Note, I've just submitted this for publication, so it may not yet be publicly available - it is Sunday, after all! Ideally, it should probably be a collection of CMF-link objects, which would then be searchable, discussable (and rateable in the near future!). But I didnt want to clutter up the Dogbowl at this stage, in case the idea didnt catch on! :-) Comments, suggestions, additions and corrections welcomed! Cheers, Jon

newbie: superuser login authorization failed
by Nicole Lallande 17 Jun '01

17 Jun '01

Source of installation binaries: http://starship.python.net/crew/jrush/Zope/Zope232.html - rpm install with zserver rather than apache pcgi install (I am still trying the rpm installation vs tarball.) OS: RH7.0 Python: python-1.5.2-27 Browser: NCommunicator 4.77 Resources: 1. mailing list archive: I found a thread written by Darci and Chris - Darci was having the problem of loging in as superuser - but then seemed to resolve the problem by stopping and restarting zope - which I did ad naseum. 2. zopedocs 3. zope help I know it isn't the information in the access file because I ran 'python zpasswd.py -u superuser -p mynewpassword -d localhost' - nada - 'Authorization failed' I have tried using NN6 - no joy. a look at the authfailed page source shows:  well - that went right over MY head! On the mailing list whenever anyone mentions having a problem with the rpm installation the response is try the tarball install. I really do not want to do that if I can avoid it so if there is anyone out there who can help me with this..please? TIA, Nicole -- ######################## Nicole Lallande nicole(a)nmlconsulting.com 760.753.6766 ########################

newbie q: error messages after install - RH rpms
by Nicole Lallande 17 Jun '01

17 Jun '01

Hi all, I have downloaded and installed all the files, and yes zope is running - when I tried localhost:8080/manage it did not work and so I changed it to localhost:8021/manage because that seems to be the port it is running on: python z2.py -p /var/zope/Zope.cgi -u zope -z /usr/share/zope -Z /var/run/zwatchdog.pid -w -f 8021 -m -l /var/log/zope so - after running that command I get: 220 mango FTP server (Medusa Async V1.12.4.1 [experimental]) ready. 500 'GET': command not understood. 500 'Connection:': command not understood. 500 'User-Agent:': command not understood. 500 'Pragma:': command not understood. 500 'Host:': command not understood. 500 'Accept:': command not understood. 500 'Accept-Encoding:': command not understood. 500 'Accept-Language:': command not understood. 500 'Accept-Charset:': command not understood. > at which point it just hangs. Apologies if this q has been addressed before but I did: try your documentation look through your archives.

DTML<->Python confusion (RE: [Zope] How to make a script return rendered dtml)
by Bjorn Stabell 17 Jun '01

17 Jun '01

I've spent hours, maybe days, being confused about this as well. According to the Zope API documentation and ZDP at http://zdp.zope.org/projects/zfaq/faq/DTML/959888072 http://zdp.zope.org/projects/zsnippet/snippets/DTMLTags/CallingDTMLMetho ds someDTMLMethod(_.None, _) should work. Because of the unclear/complex calling conventions and integration between DTML and Python I've had to keep some code in DTML. Other related questions are: How do you do dtml-with and dtml-let in a Python script? (I.e. put something on the namespace) How do you give positional (not keyword) arguments to a DTML method; is there any difference? When is __call__ called, when is __str__ called, and when is index_html called? Other basic functions worth knowing about for a class/object to be a good-behaving Zope object? When does RESPONSE need to be passed; it can always be gotten from the REQUEST, right? Calling a DTML method, when to use client and when to use REQUEST? Is calling with client and REQUEST the same as adding client to the namespace (REQUEST) and calling it with an client=None? Are namespace, _, REQUEST, and context just different names for the same thing? I've been dreaming about a FAQ answering all of this (and a bunch of ZClasses questions I have). Me thinks the ZDP should be integrated with Zope.org, and all Zope.org members given access to add FAQs (I am not allowed to add FAQs now). Ideally, somebody should be adding FAQs all the time, and the FAQ index should be posted regularly to zope-dev... Btw, I think http://zdp.zope.org/projects/zfaq/faq/DTML/959888072 gets the order of aMappingObject and aClient wrong in the first code line.

Login question
by Mike Groves 17 Jun '01

17 Jun '01

Hello, I've just started using Zope and am having great fun setting up a new site. However, I'm having a few problems setting up user login. I need the ability to allow users to log in and log out using forms, instead of the standard Zope user folder http authentification. I'm not using any of the content management/portal products (CMF etc.) and I've had a look at most of the products in the User Management section of zope.org including LoginManager, but I can't seem to work it out. Has anyone got a simple example showing me how to add users, and a simple login and log out form for either LoginManager, CookieCrumbler or anything else? Thanks very much for any help Mike Groves

script to dynamically update fields in SELECT
by Konstantinos Margaritis 17 Jun '01

17 Jun '01

Hi, I made this script because I wanted to dynamically update the contents of a SELECT field based on the choice in another SELECT. The contents are updated from a <dtml-in> call, in my case from a SQL query. It took me a while to create, and I thought that someone else could use it. Feel free to include it in a FAQ, guide, tips, etc. Comments about the script: * Create the arrays you want in Javascript to be populated by dtml-in. For some reason if I could not make it work if I used identation. keep it all on the same line. * I used a clone() function that I found in some other site to copy the wanted array in itemArray and create the SELECT object using itemArray. * This script uses DHTML show & hide functions. So I doubt it will work in older browsers (actually I don't even know if it will work on anything other than IE. But I plan to test it at least on Konqueror). Regards, Konstantinos Margaritis Script here ----------------- <html> <head> <script language="JavaScript">   </script> <style type="text/css"></style> </head> <body> <form> <select name="choice" onChange="showTable('table', this.form.tableKey, this.selectedIndex);"> <option value=-1>None</option> <option value=1>Games</option> <option value=2>Products</option> </select> <div id="table" class="myStyle"> <select name="tableKey"> </select> </div> </form> </body> </html> -----------------

dreamweaver and addresstranslation
by Robert Rottermann 17 Jun '01

17 Jun '01

Hi there, I try to use Dreamweaver together with WebDAV. After I changed all my dtml methods and documents to have an extension of .html I can load them into dreamweaver change them and save them back. Very nice indeed. Now my question: All my symbolic addresses like URL1 are translated to their physical address. so URL1 might become www.myserver.com:8080/directory/x This is fine and allows me to see the real thing (where as with ftp I only see the structure). However, when I send the data back, these address are not translated back to their symbolic counterpart. Is their a way to deal with that save of translating them by hand ?? thanks for your ideas Robert

Re: [Zope] Time-consuming External method blocks Zope execution
by shawn grant 17 Jun '01

17 Jun '01

I have been unable to get this method to work. I went to the Netscape page and tried their example. It didn't work with Netscape 4.75 on windows or linux (as well as IE and mozilla). Is this still a supported mimetype? Has anyone gotten this to work in or outside of zope?

dcoracle2
by Meilicke, Scott 16 Jun '01

16 Jun '01

Hello all, I'm trying to figure out what else is needed to use dcoracle2 besides zope. I have downloaded DCO2-NT-Beta3.ZIP and installed for use on my NT based 2.3.0 zope. When I restart zope, it reported missing oracle dlls. So I copied all of my oracle client (8.0.6) dlls to a folder in my dll path. Now when I start zope, I get the following traceback in the ZOracleDA product: Traceback (innermost last): File "D:\PROGRA~1\intranet\test01\lib\python\OFS\Application.py", line 528, in import_products product=__import__(pname, global_dict, global_dict, silly) File "D:\PROGRA~1\intranet\test01\lib\python\Products\ZOracleDA\__init__.py", line 91, in ? import DA File "D:\PROGRA~1\intranet\test01\lib\python\Products\ZOracleDA\DA.py", line 91, in ? from db import DB File "D:\PROGRA~1\intranet\test01\lib\python\Products\ZOracleDA\db.py", line 89, in ? import DCOracle2, DateTime File "D:\PROGRA~1\intranet\test01\lib\python\Products\ZOracleDA\DCOracle2\__init_ _.py", line 37, in ? from DCOracle2 import * File "D:\PROGRA~1\intranet\test01\lib\python\Products\ZOracleDA\DCOracle2\DCOracl e2.py", line 63, in ? import dco2 ImportError: DLL load failed: The specified procedure could not be found.
