I'm new in ZOPE and then have some questions: 1) What the difference between DTML documents and DTML methods? (both are display it contents, to both may transmit parameters, what else?) 2) How I retrieve name of the previous document that has been browsed before this? Thanks in advance.

Zope with alternate python

How do you change Zope to run with an existing python installation instead of the one that comes packaged with the Windows distribution? Thanks.

This is a known bug in 1.11.0pr 1 that has been fixed in Zope 2.0.0a1. Image objects declared the width and height properties to be integers (to Zope, not to python, which is loosly typed), and when it figures out the width and height up uploaded files, it stores them as strings. The new 1.11.0pr1 property displaying code hits it's head on this when it tries to display these 'integers'. The properties are now declared as string. This way you can also change the width and height properties to a percentage (like 100%) of the browser size. -- Martijn Pieters, Web Developer | Antraciet http://www.antraciet.nl | Tel: +31-35-6254545 Fax: +31-35-6254555 | mailto:mj@antraciet.nl http://www.antraciet.nl/~mj | PGP: http://wwwkeys.nl.pgp.net:11371/pks/lookup?op=get&search=0xA8A32149 ------------------------------------------

HELP: ZPyGreSQLDA doesn't work, db.py does.
by Evan Simpson 29 May '99

29 May '99

I've got Zope 1.10.2 working great on a RedHat 5.1 i386 box, with Python 1.51, PostgreSQL 6.3.2, and the latest ZPyGreSQLDA from zope.org. If I run Python in the Products/ZPyGreSQLDA directory, I can do the following: >>> import db >>> c=db.DB('zope nobody') >>> c.query('select * from person') ([{'width': 4, 'name': 'name', 'type': 't'}, {'width': 5, 'name': 'phone', 'type': 't'}, {'width': 6, 'name': 'salary', 'type': 'n'}, {'width': 8, name': 'children', 'type': 'i'}], [('fred', '555-1212', 0.0, 0)]) >>> I can run queries to my heart's delight, but when I fire up Zope the Product is broken, with: ZPyGreSQLDA Import Traceback Traceback (innermost last): File "/home/evan/Zope-1.10.2-src/lib/python/OFS/Application.py", line 395, in import_products product=__import__(pname, global_dict, global_dict, silly) File "/home/evan/Zope-1.10.2-src/lib/python/Products/ZPyGreSQLDA/__init__.py", line 89, in ? import sys, os, Globals, DA File "/home/evan/Zope-1.10.2-src/lib/python/Products/ZPyGreSQLDA/DA.py", line 91, in ? from db import DB File "/home/evan/Zope-1.10.2-src/lib/python/Products/ZPyGreSQLDA/db.py", line 89, in ? import _pg, regex, sys, types ImportError: /home/evan/Zope-1.10.2-src/lib/python/Products/ZPyGreSQLDA/_pgmodule.so: undefined symbol: PQsocket I compiled _pgmodule.so with -DNO_PQSOCKET.

It's very easy though, go to the pipermail archive, sort the month of May by author and look for Amos. On Tue May 6th he posted his ZClass tutorial rough draft. -Michel > _______________________________________________ > Zope maillist - Zope(a)zope.org > http://www.zope.org/mailman/listinfo/zope > > (For developer-specific issues, use the companion list, > zope-dev(a)zope.org - http://www.zope.org/mailman/listinfo/zope-dev ) >

Zope comes with a handful of python extensions written in C for speed. Although we provide binary releases for stable, beta and pre-releases, we do not provide binaries for alpha quality code. If you are running Linux, you must run the wo_pcgi.py script to compile the extensions (you must have gcc and the c library installed, which comes by default for most versions of Linux and other *NIX OSes, you must also have Python 1.5.2 installed). If you are runnign Windows, you will need a C compiler. The long and short of it is, we want you to use the alpha code if you like living on the bleeding edge and running into and helping fix bugs. Otherwise, we recommend you use one of our stable releases. The current stable release is 1.10.2, and there are precompiled binaries for Linux, Solaris, and Windows. It's possible someone on the list can get you a precompiled BSD version. I beleive we plan on supporting BSD binaries in future releases, but I'm not the one to say for sure. -Michel
