Output only the first or a particular record using TAL
by Julian Yap 14 Sep '05

14 Sep '05

Hi all, I wanted to create something of a header using TAL and a Z SQL Method. I have the following code where getCustomerLicenses is my Z SQL Method and it prints out the customer's full name with details: <tr tal:repeat="licenses container/getCustomerLicences"> <td><span tal:replace="licenses/full_name">full_name</span></td> <td><span tal:replace="licenses/serial_number">serial_number</span></td>  </tr> In it's simplest form, how do I retrieve just the full_name of the first record using TAL. I think I use tal:replace but I'm not sure. I was along the lines of something like this: <tr tal:define="x container/getCustomerLicences"> <td tal:replace="x/full_name[0]></td> </tr> But then I just get a TypeError. I guess if I get this working, I can start playing around with conditions but I'm stuck! Thanks, Julian Yap

mysql-python build error
by Sophia Grimm 13 Sep '05

13 Sep '05

I installed Plone 2.1 from the binary installer at plone.org and MySQL 4.1 from the binary at mysql.com. When attempting to build MySQL-python-1.2.0 on MOSX 10.4.2 client, I get this error: sh: line 1: mysql_config: command not found sh: line 1: mysql_config: command not found running build running build_py running build_ext building '_mysql' extension gcc -bundle -undefined dynamic_lookup build/temp.darwin-8.2.0-Power_Macintosh-2.3/_mysql.o -L/usr/local/mysql/include -lz -lmysqld -o build/lib.darwin-8.2.0-Power_Macintosh-2.3/_mysql.so /usr/bin/ld: can't locate file for: -lmysqld collect2: ld returned 1 exit status error: command 'gcc' failed with exit status 1 Obviously, it's looking for -lmysqld. I don't know where to change setup.py (or what to change it to) so this will work. Any tips are appreciated!! SG __________________________________ Yahoo!

Re: [Zope] Re: Zope iso-8859-1 to utf-8

Thanks Dieter, you are right, I was a little confused. I think that if my pages did not break so far it's because we use html entities for non standard characters... I will have to convert everything in a rush now to avoid issues :( -------------------------- (sent from my BlackBerry) -----Original Message----- From: Dieter Maurer <dieter(a)handshake.de> To: Pascal Peregrina <Pperegrina(a)Lastminute.com> CC: 'Max M' <maxm(a)mxm.dk>; zope(a)zope.org <zope(a)zope.org> Sent: Tue Sep 13 19:10:08 2005 Subject: RE: [Zope] Re: Zope iso-8859-1 to utf-8 Pascal Peregrina wrote at 2005-9-13 14:21 +0100: >I see...

The problem does not lie with the characters but with their codes. The code agrees between UTF-8 and iso-8859-1 for precisely the ASCII characters (unicode chars 0-127). Unicode characters 128-255 use 2 bytes in UTF-8 but 1 in "iso-8859-1". Unicode characters 256 and up can be represented encoded in "UTF-8" but not "iso-8859-1". > ... >Last thing, if ZMI is switched to UTF-8, then what is the difference between >ustring/string, etc properties ? "ustring" is a unicode string: stored inside Zope as unicode, sent to the browser UTF-8 encoded and expected to come back UTF-8 encoded. "string" is a plain (non unicode) string. It should use the encoding of your page (UTF-8, once you switched to UTF-8). -- Dieter ********************************************************************** 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.

About High Level Query Languages
by Enrique Arizón 13 Sep '05

13 Sep '05

I was browsing different solutions/products to query the Catalog with a high level language similar to SQL and it looks to be more than one solution: http://www.zope.org/search?SearchableText=Query+Language The question is whether an standard query language exists or not yet for Zope/Plone.

Zope 2.8.1 won't "make"
by Sophia Grimm 13 Sep '05

13 Sep '05

Just downloaded Zope 2.8.1 and I'm trying to install it on MOSX 10.4, which has XCode 2.1 installed. I'm following installation instructions on this page: http://www.plope.com/Books/2_7Edition/InstallingZope.stx#2-6 ./configure runs, but when I try to make, I get this error: makefile:54: *** target pattern contains no `%'. Stop. This happens regardless of the python or prefix I use as arguments when I configure. I've used Python 2.3.5 which comes with MOXS 10.4, and I've used Python 2.3.5 as installed by Fink. I don't understand what this error means. Any ideas, anyone? Thanks in advance. SG __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

Zope iso-8859-1 to utf-8
by Pascal Peregrina 13 Sep '05

13 Sep '05

Hi, I have been running a Zope installation for 2 years, so there are now lots of objects, properties, etc... I would like to know what are the possible issues I may have to face if I change the default encoding for iso-8859-1 to utf-8 in ZMI. Thanks.

RE: [Zope] MemoryError that brings my zope to its knees

That looks wierd... Has the instance been running for a while when you copied the content of the Cache Parameters tab ? I would have expected many more connections (instead of just 2). Can you give us your zserver-threads value (zope.conf) ? Thanks.

When we started having this problem the box only had 1GB of RAM so we replaced that RAM completely and put in a fresh 4GB of RAM to hopefully get rid of the problem. This box is also running 3 other Zope instances, but the other don't exhibit this problem. This instance has 15 plone site instances in it. The others only have a couple plone sites each.
