ZServer log format
by Itai Tavor 10 Sep '99

Hi, I want to ditch Apache and use ZServer directly... but I got Apache to write HTTP_AGENT and HTTP_REFERER to the access log file, which medusa doesn't do. I couldn't find a way to customize the logs in medusa in the docs and after a quick look through the code. Is it possible? Or can anyone point me to the place in the code to add a patch?

This worked great Bruce. Thank you. Althought this wouldn't solve the problem for creating packages to distribute, it does indeed solve my needs and so I am very very grateful : I can finally get on with building my app (after over 24 hours complete downtime trying to solve this). Am cc'ing the list because this deserves to to be in the archive and may prevent somebody else from wasting too much time.

Re: [Zope] ZCatalog, SQL database and PDF files

Did anyone have done something like that successfully? To people like me, a How-To is needed seriously! Also, one more question for combining ZCatalog and SQL Database searching -- do I really need to index the data in the SQL database into the ZCatalog when they are already indexed in the SQL database? Can I somehow link the ZCatalog to a SQL search interface so that when I search a ZCatalog, it will trigger the SQL search, and at the end combine the result into one report? Or, am I making it more complicated than it should be? Kam

Need ZCatalog help
by John Goerzen 10 Sep '99

10 Sep '99

Hi! OK, it looks like I've been doing things a stupid way by not using ZCatalog. I managed to find a ZCatalog.txt buried deep within the source, but I'm a bit stuck now. First. I created a ZClass in my own Application with my Events class. Do I need to delete it and recreate it so that it lists ClassAware as one of its meta types? When a class is ClassAware, how does it know into which catalog new items should go? I haven't been able to make the thing update catalogs automatically. What is the purpose of using the Contents tab of a ZCatalog to actually add items inside it? What are the pros/cons of doing this? Why are these objects not automatically cataloged? Where can I find a reference on the syntax of searching a catalog? Thanks, John

Calendar ZSIG?
by Andrew M. Kuchling 10 Sep '99

10 Sep '99

There seem to be several Zope-related applications where you want to deal with calendars and events. Some people want to display relatively static calendars of upcoming events such as conferences and shows; others want to write more dynamic scheduling systems where people can manage their scheduling; personally, I want to display historical database information, so you can say "Hey! Nothing's happened for a week!". The CalendarTag is quite useful, but it could be a good deal more flexible and the display could be improved in various ways. Philip J. Eby had several suggestions for a design for calendar events, in the thread starting from this post: http://www.zope.org/pipermail/zope/1999-September/009591.html Question: is there enough interest in scheduling to make it worth creating a Zope SIG for working on the topic? The initial deliverable might just be an enhanced version of Ty Sarna's CalendarTag that's a bit more configurable. Or should I simply discuss this on the already high-traffic Zope list, or zope-dev? (But zope-dev for development of Zope, not Zope add-ons.) Suggestions? -- A.M. Kuchling http://starship.python.net/crew/amk/ The road ahead can hardly help being strewn with many a mistake. The main point is to get those mistakes made and recognized as fast as possible! -- John A. Wheeler

Re: [Zope] Need ZCatalog help

Here I am talking to myself again :-) I have two more questions to go along with the below. I have made a ZCatalog up near the top of my tree named EventsCatalog. I have a method named getEventsByDate that now usses this. This method works fine if invoked directly, but if not, it claims it can't find EventsCatalog -- even if both the method and the caller are clearly below EventsCatalog in the tree, thus acquisition should step in. Here's the code: <dtml-with "_(myEventList=[])"> <dtml-in "EventsCatalog.searchResults({'when' : [startDate, endDate], 'when_usage' : 'range:min:max'})"> <dtml-call "myEventList.append(EventsCatalog.resolve_url('/' + EventsCatalog.getpath(data_record_id_), REQUEST=REQUEST))"></dtml-comment> </dtml-in> <dtml-return myEventList> </dtml-with> Now, it is aborting at searchResults. Secondly, the search string *may* be working, but I don't understand the syntax. What do the colons and the curly braces signify? Why is "_usage" significant? What exactly does 'range:min:max' indicate? Thanks! John Goerzen <jgoerzen(a)complete.org> writes: > Hi! > > OK, it looks like I've been doing things a stupid way by not using > ZCatalog.

I suspect the problem is that I wasn't using ZCatalog at all :-) Primarily because I still can't figure out how to make the darn thing work. But thanks to people in this group, I'm making progress :-) Once I get everything going, I'm going to have to join the documentation project, I think. -- John
