Why does ZPublisher Client screw up request path?
by Kyler B. Laird 15 Feb '01

15 Feb '01

I've been trying to follow the example at http://www.zope.org/Members/lstaffor/ZClientMethod for using ZPublisher Client to grab some info via HTTP. While this works for URLs like http://www.ecn.purdue.edu/~laird/test/set it fails for http://www.ecn.purdue.edu/Engr/ because __init__ has while url[-1:]=='/': url=url[:-1] I suggest that a "Don't mess with my path" flag be added. Since I'm calling this through an External Method, I can set the flag there so that users won't have to see it. Thank you. --kyler

External Method - "context" arg
by Tom Sheffler 15 Feb '01

15 Feb '01

The Zope book chapter "Advanced Zope Scripting" shows a method with an arg list like this: def makeThumbnail(context, original_id, size=128): When I create a method with the "context" arg, Zope complains that the parameter "context" was omitted from the request. THE REAL QUESTION::: Using a Python Method, it's easy to get the variables "context" and "travers_subpath." How do I get these two values when using an External Method. Thanks for any assistance.

re:[Zope] MySQL, PostgreSQL, etc
by Oliver Bleutgen 15 Feb '01

Just one small addition to many excellent points which were brought up in other postings. If maximum size of a row is of interest, be sure to check also this data out. IIRC, since version 7.1, postgresql's maximum row size is very big, (2 GB?), don't know wheter mysql is also capable of that. cheers, oliver

_mysql.so causes problem
by Peter Bengtsson 15 Feb '01

15 Feb '01

Infinite problems with MySQL and Zope and MySQL-python (which used to be called MySQLdb before right) - I downloaded the latest MySQL-python 0.3.3 - Followed the instructions carefully. Had to install the python-devel kit for Distutils. - # python setup.py build and install gave me a C parse error at line 1678 in _mysqlmodule.c which I fixed. Anyhow I now have a file called _mysql.so in /usr/lib/python1.5/site-packages/ <zopedir> ./start Complains the usual (common problem according to endless searches on the mailing list archive) Traceback (innermost last): ImportError: No module named _mysql So I copy /usr/lib/python1.5/site-packages/_mysql.so to <zopedir>/lib/python/Products/ZMySQLDA/ Now this is the error I get: 2001-02-15T13:00:06 ERROR(200) Zope Couldn't import Products.ZMySQLDA Traceback (innermost last): File /home/zope/Zope-2.3.0-linux2-x86/lib/python/OFS/Application.py, line 530, in import_products (Object: string) File /home/zope/Zope-2.3.0-linux2-x86/lib/python/Products/ZMySQLDA/__init__.py, line 91, in ?

ImportError: /home/zope/Zope-2.3.0-linux2-x86/lib/python/Products/ZMySQLDA/_mysql.so: undefined symbol: Py_InitModule3 In the mailing list archives I've seen this error before, but no concrete solution other than "check your paths to mysql" etc. Zope 2.3.0 RedHat 6.2 Mysql 2.23.32 Python 1.5.2 (with python-devel) Can somebody suggest a good _combination of versions_ to be used because the box hasn't been hooked up yet and we can reinstall a lot from scratch if necessary. Really really grateful for advice, Peter

MailHost problem after upgrading to 2.2.4
by Edwin Martin 15 Feb '01

15 Feb '01

I have upgraded my Zope to 2.2.4. Now my MailHost product will not work anymore. On the Zope website I can't find information to solve this. Before the upgrade, I had in the Zope-root a MailHost instance, which worked ok. After the upgrade, mail didn't work and when I clicked the MailHost instance, I got an error. I deleted the instance and now, when I'm addind a new MailHost instance, I get an error. I entered: Id: MailHost SMTP Host: <my-ip-number> SMTP Port: 25 When I look in Control Panel -> MailHost, I see a Help folder. This is the error I get after 'adding' a MailHost: <TD WIDTH="90%"> <H2>Zope Error</H2> <P>Zope has encountered an error while publishing this resource. </P> <P><STRONG>Resource not found</STRONG></P> Sorry, the requested Zope resource does not exist. --> <HR NOSHADE> <P>Troubleshooting Suggestions</P> <UL> <LI>The URL may be incorrect.</LI> <LI>The parameters passed to this resource may be incorrect.</LI> <LI>A resource that this resource relies on may be encountering an error.</LI> </UL> <P>For more detailed information about the error, please refer to the HTML source for this page. </P> <P>If the error persists please contact the site maintainer.

RE: [Zope] How to insert NULL values
by Farrell, Troy 15 Feb '01

15 Feb '01

Ok. Now for my next magic trick: I would try modifying the ZSQL method. Try something like: INSERT INTO introduzioni ( codice_fiscale, distretto, marca_precedente ) VALUES ( <dtml-sqlvar CODICE_FISCALE type="int">, <dtml-sqlvar DISTRETTO type="string">, <dtml-if "_str(marca_precedente) == ''"> NULL <dtml-else> <dtml-sqlvar marca_precedente type="string"> </dtml-if> <dtml-var sql_delimiter> This will Submit NULL (not 'NULL') if the string is empty. I didn't test this, so it might have a bug or two :) Note that your ZSQL method may be totally different, and I am just guessing at it based upon your parameters.
