Python source install problem
by Oliver Wrede 18 Jan '00

18 Jan '00

Hi. I try to follow Alans kind instruction on http://www.zope.org/Members/alanpog/zmysqlda_steps I downloaded the source of everything. I used the source release of MySQL-3.22.25, because I ran into compile problems with newer versions. After configuring and making python I do a "make install" on the python source and after a while get following error: ./python /usr/local/lib/python1.5/compileall.py /usr/local/lib/python1.5 ./python: error in loading shared libraries: libmysqlclient.so.6: cannot open shared object file: No such file or directory make: *** [libinstall] Error 127 What is the special problem here? Can you help me? What version of MySQL are you using? I have to run the latest MySQL-3.22.30 on my machine. Is that conflicting here? (I changed the path in Python-1.5.2/Modules/Setup to point to the 3.22.25 distributions mysql lib&include files....!) Oliver .. Oliver Wrede .. owrede(a)khm.de .. Academy of Media Arts, Cologne ..

Zope design: the liberal use of subclassing?
by Darran Edmundson 18 Jan '00

18 Jan '00

One component of our budding academic site is a searchable database of publications authored by department members. Publications come in various flavours: journal articles, conference proceedings, books, book chapters, etc. All of these share certain properties while others are unique. Question: In terms of ZClasses, is it best to create an abstract Publication ZClass with common data and methods and then subclass the various flavours? In addition to publication details, I also want the option of encapsulating the data files, be it in PDF, MSWord, ASCII, TeX format, etc. Question: Rather than create a slew of File-like products in the root Product folder, should I again create an abstract class and subclass for each Mime type a la the PDF example used in: http://www.zope.org/Members/lstaffor/zProperties The same applies for People, variants of which include staff, students, alumni, visitors, etc., with the difference that people can migrate from one class to another (student to alumni). Summary Question: Generally speaking, rather than create a slew of ZClasses in the root Product folder, should one liberally subclass? Advice on these critical design decisions is most appreciated. Darran.

Sounds like inheritance. > Question: In terms of ZClasses, is it best to create > an abstract Publication ZClass with common data > and methods and then subclass the various flavours? It's a philosophical issue, but I would say that soulds like a good plan. > In addition to publication details, I also want > the option of encapsulating the data files, be it in > PDF, MSWord, ASCII, TeX format, etc. You want Zope to *interpret* their content somehow? Or just have nifty labeled File objects? > Question: Rather than create a slew of File-like > products in the root Product folder, should I again > create an abstract class and subclass for each > Mime type a la the PDF example used in: > http://www.zope.org/Members/lstaffor/zProperties Zope's file object allready has mime-typeablity and storage, if you don't want to parse/interpret the contents of a special file I don't see why you can't just use the stock file object. > > The same applies for People, variants of which > include staff, students, alumni, visitors, etc., > with the difference that people can migrate from one > class to another (student to alumni). Do you want these people objects to also participate in authentication/authorization? In this case you should go with standard Zope user objects and Roles. -Michel

You can also set an env variable in your rewrite rules (in fact, setting AUTHENTICATED_USER in the rewrite rule IS an env var. -Michel

re: SQL Unions.
by Brenton Bills 18 Jan '00

18 Jan '00

Hi people, I have been attempting to do an SQL union from an ZSQL Method with MysqlDA as my back end database. The only problem is I cant seen to get it to work. Are unions a bad thing? Should I be using something else. Eg. Get all the brands we have in our database. select brand from tableofitemsoftype1 union select brand from tableofitemsoftype2 group by brand. >From what I understand this would get all of the brands and group them together and place them in a single column results table?

problem creating ZClasses inside ZClasses
by Andy Pahne 18 Jan '00

18 Jan '00

Hi there, I know we had this thread already a few weeks ago - and a possible solution to my problem: When I try to create a ZClass inside another existing ZClass, the inner ZClass does not show up in the global product add-list. And also the inner ZClass does not appear in the list of possible subobjects. (The Zope developers guide tells me it should automatically). I searched the mailing list at eGroups, but I was not able to find the thread. Does anybody remember this discussion or he name of the thread? Thanks in advance, Andy Pahne ap(a)net22.net
