ZClass Date Fields
by Craig 24 Aug '00

24 Aug '00

I'm sure you've heard this question before, so bare with me. I went through the ZClass tutorial and got everything working right except Date properties. Lets assume, for example, that my ZCLass is called CDClass. When I create a new CDClass instance (using the addForm), it always uses the default date for Date properties instead of the ones I've entered in the form. A co-worker of mine has had the same problem but we have not yet discovered why. Thoughts? Solutions?

Can't compare apples to apples. (document_id != id_of_my_document)
by T.J. Mannos 24 Aug '00

24 Aug '00

Hi, there, I have a DTML document called "apples". A call to <dtml-var document_id> gives the string "apples" However, a <dtml-if "document_id == 'apples'"> returns false. Am I missing something? I've tried _.str(document_id) and even _.string.strip(_.str(document_id)). Thanks, T.J.

Simple Directory of URLs problem (Waaa)
by Peter Be 23 Aug '00

23 Aug '00

Roug Installing your Simple Directory of URLs gives me this message when I start up Zope on window98. "that is not valid. This should never happen. (Waaa)." There is something wrong with the permissions I guess but I can't see the error message it generates because either I'm stupid or MS DOS PROMPT is to short on lines. If it was Linux I could at least have scrolled upwards to see the whole error message. I can see that the error must occur in PermissionMapping.py I run Zope 2.2.1b1 on Windows98. The tgz file I downloaded contained three files. __init__.py, version.txt and product.dat. Is that correct? The problem is, that I can't see or Add the Simple URL object from my Add dropdown list. Why is that? I have so far never had any problems with this setup. (I think) It is a development server, so I can knock it off and start again if I have to. I have followed the Installation instructions, and I have successfully installed your product previously on Zope 2.1.6 Cheers, Peter

Re: [Zope] Microsoft SQL Server Access under Linux?
by Anthony Baxter 23 Aug '00

Use Sybase. Sybase even provide the client libs for download for *ahem* evaluation. MS SQL == Sybase wearing a pair of bad Groucho Marx glasses/nose/mustache (aka an annoying management GUI) Or FreeTDS, but last time I looked that wasn't threadsafe.

Re: [Zope] newbiz : zope connection

HTTP is a connection less protocol (to be precise, HTTP 1.0). Thus, a priori, there is no notion of connection: A user is only connected to the server for the duration of a single request. The connection is closed as soon as the request is completed. Zope 2.2 has a facility in its Control Panel where you can see, how much requests are currently in work. This gives you the 'currently' connected users. To get more information, you would analyse ZServer's log file: "var/Z2.log". It contains an entry for each HTTP request. There are tools to analyse such a log file. Search the mailing list's archive for suggestions for such tools.

Re: [Zope] How to test if an object exist

I hope, you are not, because the method cannot raise a (NameError,folder1). Anyway, if your problem is in Python code, the traceback contains precise line number information for the problem. In order to test, whether an object O can access another object o, you can use: "hasattr(O,'o')". In your example: if hasattr(self,'folder1'): return 'Object exists' This will not test, that 'folder1' is contained in "self" but that a 'folder1' is accessible (acquired) in "self". In order to test for direct containment, you would use "self.aq_base" instead of "self". Dieter

For a DTML method(!), "id" is the id of the object of which the method is used as a method. In your case, this is the folder. In some cases, you would use "this().id". This gives you the id of the "top level" DTML object. In your case, this would be "index_html". Dieter

Re: [Zope] processing dtml in external method
by Dieter Maurer 23 Aug '00

23 Aug '00

Scott Shepherd writes: > I have an external method that returns a string containing dtml, but > I want it to evaluate the dtml and return the result. How do I do > that? "evaluating dtml" means calling it. The "__call__" of DTML methods, or, more generally, DocumentTemplates, has two positional parameters, "client" and "REQUEST", and an arbitrary number of keyword parameters. "client" is "None", a single object or a tuple of objects, "REQUEST" is "None" or a mapping, the keyword parameters are anything. The parameters determine, what bindings (i.e. name -> value mappings) are available in the DocumentTemplate's namespace. If there are conflicts, the higher priority source wins. The priority order is as follows (highest priority first): * keyword parameters * attributes of client (I am not sure about the relative priority in the case of more than one clients. I believe to remember that later clients have higher priority) * the mapping. Dieter

Using crontab instead of rc.d
by George Osvald 23 Aug '00

23 Aug '00

Hello everyone! My ISP where I have my web page, is running freeBSD 4.0. I do not know a lot about it. I know how to use crontab to start ZOPE at certain time how ever how do I use crontab to check on the script that is already running? Starting ZOPE again when it's running produces an error message and I do not know if that was a healthy solution. to start it I would be using something like: 5 * * * * root ./start This would start the script every five minutes. Now how do I check if the script is running after it's been started and if it wasn't to restart it again. Also I was thinking to run ZOPE in DEBUG mode. That way it stays attached to the terminal (crontab I guess). I know about z2.pid. Nevertheless I find ZOPE down quite often every time they do something at the ISP. I asked them what to do and they told me to use crontab to check the script and restart it. For some reason they don't want me to use rc.d If I could guarantee to remove the z2.pid every time ZOPE goes down, I could apparently include something like this: if [ -x /home/virtuals/account/zope/z2.pid ] then // exit(0) fi 5 * * * * root ./start to check if the file is present and if not to run the script. That can't be done when ZOPE exits abnormally though. Is this setup at all possible? Regards, George Osvald
