ZClasses and SQL Result classes.

Is it possible, or going to be possible, to wrap the results of an SQL query in a ZClass instance, rather than a python one? Anthony

help :( ... entire site disappeared
by Daniel M. Drucker 16 Jun '99

I reinstalled Zope2, having saved my var directory to another location. I shut down zope properly before saving that directory. Now, when I put the files from the old 'var' into the new 'var', the new Zope2 doesn't see them and just gives the default view with acl_users, control panel, and standard_*. Have I lost everything? What happened? Why doesn't it recognize my Data.bbb?

ZORB3 Errors
by J Kinsley 16 Jun '99

16 Jun '99

After posting this error yesterday and getting no reply, I decided to verify that it was not due to something left over from a previous installation. I dumped my entire installation into another directory and untarred Zope-2.0.0a2 into an empty directory. Then did the following: $ python w_pcgi.py $ ./start Upon entering the root manage view, the first thing I noticed was the QuickStart which I had never seen before. I then went to Control_Panel/Database/manage_cacheParameters and no error. Next I tried Control_Panel/Database/manage_cacheGC and again no error. At that point I thought I had solved the problem and backed out to Control_Panel when I noticed there was no restart button. Remembering that the Restart button was part of ZServer, I shutdown the Zope process and went back to look at the start file. There I changed python serve.py to python z2.py and restarted. Now upon entering the root manage view, the first thing I noticed was QuickStart was no longer visible. I proceeded to the Control_Panel/Database/manage_cacheParameters and there was the TypeError exception again. I backed out and tried Control_Panel/Database/manage_cacheCG and again there was the TypeError exception. Here again is the traceback output which is exactly the same for both cases. exceptions.TypeError Traceback (innermost last): File /opt/www/zope/lib/python/ZPublisher/Publish.py, line 255, in publish_module File /opt/www/zope/lib/python/ZPublisher/Publish.py, line 161, in publish File /opt/www/zope/lib/python/ZPublisher/mapply.py, line 154, in mapply (Object: cacheParameters) File /opt/www/zope/lib/python/ZPublisher/Publish.py, line 98, in call_object (Object: cacheParameters) File /opt/www/zope/lib/python/App/special_dtml.py, line 120, in __call__ (Object: cacheParameters) File /opt/www/zope/lib/python/DocumentTemplate/DT_String.py, line 514, in __call__ (Object: cacheParameters) File /opt/www/zope/lib/python/App/CacheManager.py, line 109, in cache_length (Object: Control_Panel) File /opt/www/zope/lib/python/ZODB/DB.py, line 272, in cacheSize TypeError: too many arguments; expected 1, got 2 The problem starts in App/CacheManager in cache_length() where it determines we are not using BoboPOS2 and tries to return db.cacheSize(). When using serve.py, we are using BoboPOS2 and thus the error in ZORB/DB.py is not encountered. At this point, I have no idea how to go about solving the problem. I have looked at the code and cannot immediately find anything wrong with it, but as I stated before, I have only been using Python for a few months so I may be overlooking something. Also, why does QuickStart show up using BoboPOS2 and not with ZORB3? Is anyone else using ZServer and getting these errors or am I the only one who seems to have this problem?

Hi, Just looking for a simple DTML example of how to use the string functions. I wish to check to see if the first and last characters of a sequence-key are a pipe character or not. Thanks, ------- Regards, Graham Chiu gchiu<at>compkarori.co.nz

2.0.0a[12] Cache Prameters / Flush Cache TypeError
by J Kinsley 16 Jun '99

16 Jun '99

I am getting a strange TypeError in both the 'Cache Parameters' and 'Flush Cache' tabs of the 'control_panel'. I had initially seen this error in 2.0.0a1 back when I first installed Zope (1.x.x never worked because I run Python1.5.2). I had forgotten about it until a little bit ago when I encountered it again in 2.0.0a2. I have searched both the Collector and the list archives and have found no mention of this error, so I am assuming it is restricted to my configuration. Below is the traceback which is exactly the same for both functions. Zope has encountered an error while publishing this resource. exceptions.TypeError Traceback (innermost last): File /opt/www/zope/lib/python/ZPublisher/Publish.py, line 238, in publish_module File /opt/www/zope/lib/python/ZPublisher/Publish.py, line 108, in publish File /opt/www/zope/lib/python/ZPublisher/mapply.py, line 104, in mapply (Object: cacheParameters) File /opt/www/zope/lib/python/ZPublisher/Publish.py, line 97, in call_object (Object: cacheParameters) File /opt/www/zope/lib/python/App/special_dtml.py, line 112, in __call__ (Object: cacheParameters) File /opt/www/zope/lib/python/DocumentTemplate/DT_String.py, line 405, in __call__ (Object: cacheParameters) File /opt/www/zope/lib/python/App/CacheManager.py, line 104, in cache_length (Object: Control_Panel) File /opt/www/zope/lib/python/ZODB/DB.py, line 267, in cacheSize TypeError: too many arguments; expected 1, got 2 I cannot seem to figure out why this is happening from the given information. However, I've only been using Python for two months and Zope for two weeks, so I may be over looking something. System Parameters: Zope-2.0.0a2 Python-1.5.2 RedHat-6.0 Linux-2.2.9 Regards, Jarrod Kinsley

FTP and apache?

I'm using Zope 2 (a2) + apache, on port 9673. FTP starts up fine on port 9221 if I use ZServer, but if I use apache (I'm using the prebuilt Zap, copied from my Zope1 installation) FTP doesn't start up. What might I be doing wrong? dmd

Will their be a non client-server version of ZODB3 which offers concurrency that will be a part of the non-commercial, open source part of Zope? Jimmie Houchin

RE: [Zope] Split the list again?

I didn't say I didn't _understand_, I just uttered my disputably subjective opinion that the rationale is utter bollocks. I accept that the statistical minority and the apparently devaluated authority of my opinion makes the difference of a pebble on a beach in this forum, and will forthwith resign to the fact that I'm obviously the newbie that you imply, and that I, as a sometime user, have no business talking about user-friendliness. I'll just go back to my BASIC programs now and ponder on the intricacies of the command "print", thanks. :) I second the idea of going NNTP. -- Alexander Staubo http://www.mop.no/~alex/ "`Ford, you're turning into a penguin.
