Check for bad links?
by Paul Winkler 14 May '01

Hi, Does anyone know a free, Zope-friendly link checker? It's tedious hunting down bad URLs in my pages by hand. The link checking programs I've tried don't seem to like Zope... -- ................... paul winkler .................... custom calendars & printing: http://www.calendargalaxy.com A member of ARMS: http://www.reacharms.com home page: http://www.slinkp.com

ZExternalNews crashing things for my Connection
by Peter Bengtsson 14 May '01

14 May '01

I installed ZExternalNews and set up a couple of Managers in a test folder. Restarting Zope with -D in the DOS propmt, this is the first two lines: ZExternalNewsManager AutoUpdate started, will awake every 15 minutes. ZExternalNewsManager AutoUpdate started, will awake every 15 minutes. And after the usual info about hostname and such, this error message is printed: 2001-05-14T15:32:04 ERROR(200) ZODB Couldn't load state for '\000\000\000\000\0 0\002\243[' Traceback (innermost last): File C:\PROGRA~1\Zope\lib\python\ZODB\Connection.py, line 477, in setstate AttributeError: 'None' object has no attribute 'load' Zope works. And it is difficult to know if it's slowed or not because it's "too fast" here on my localhost. The errormessage comes from the Zope component lib/python/ZODB/Connection.py Do you have any ideas why this is so? Is it bad? What to do? If you need more details, tell me and I shall try. The usual: Zope Version Zope 2.3.0 (binary release, python 1.5.2, win32-x86) Python Version 1.5.2 (#0, Jul 30 1999, 09:52:18) [MSC 32 bit (Intel)] System Platform win32

RE: [Zope] ODBC DSN file
by Menard.Jean-Francois＠hydro.qc.ca 14 May '01

14 May '01

Thanks Thomas, good idea. I will use LocalFS to list all the files in my directory. All I need, is a way to change the DSN parameters on the fly to point to the needed Excel file. I don't want to create 100 DSN!!! That's why I wonder if Zope can use File DSN instead of Sytem or User DSN. Maybe there would be a way to import my Excel sheets without ODBC? I need them the way they are, not in CSV format or anything... But again, thanks for the tip! -----Message d'origine----- De : Thomas B.

I tried to create a File DSN, but Zope doesn't seem to detect it. With such a connection, I could change the connection string into the DSN file when needed. [Tom] If you always know where the files are located, you could use the LocalFS product. Or you could write a simple python external method.

HELP! Double outputs!
by Paul Zwarts 14 May '01

14 May '01

Oh woe is the day.... I'm totally frazzled by this. I have moved a test zope install to a unix server running another one. Both are configured for separate ports... I have a structure something like this <var logic> <var header> <var orderform> <var footer> (very basic description) What I get is: <var logic> - okay <var header> - okay <var orderform> - okay <var orderform> - not okay <var footer> This application lives on several test machines and none of them have any such problems. What duplicates is also very selective as well... Im not sure where to go for debug info... z2.py started with the -D optioin shows nothing. Apache shows nothing (even though the problematic zope is refferenced directly to ZServer through port 8085) The logging of REQUEST and SESSION reveal nothing. Putting in <dtml-var sequence-key> doesnt show an miscreant <dtml-in> that loops one two many. I am really lost.... Its Zope-232 with PGSQL703, PoPy 2.01 and the latest ZPoPy adapter. Perhaps there is a bug here or someone has expereinced the same thing? I cant be more than vague without writing an essay... But perhaps someone can tell me how to monitor the Zope stack? Thanks very much, Paz

I made a funny experience recently: One of our low load Zope installations went into this hanging state regularly. I had the impression, it happened every day. Then I activated a checker, that checks availability every 5 minutes. The problem went away. Since then, Zope never hung again. Maybe, Zope does not like to be lazy? Dieter

how to know the parent folder
by Arkaitz Bitorika 14 May '01

14 May '01

Hi all, I've got some ZClasses in folderish objets, and I'd like to know how can I get from each object which is the parent folder in which it is stored. I guess this a very simple thing, but I haven't found the way yet ;). Any hint? TIA, arkaitz.

RE: [Zope] ODBC DSN file
by Menard.Jean-Francois＠hydro.qc.ca 14 May '01

14 May '01

Thanks for your response! Yes, I could do that, but I would like to skip this step if possible, cause I will keep receiving data form Excel sheets for a while. What I would like to do is create a web interface to let users put the exel files in a directory on the server, import the data themselves, create some transfer directives, end export the result. So, would it be possible? -----Message d'origine----- De : Tino Wildenhain [mailto:tino@wildenhain.de] Envoyé : lundi 14 mai 2001 11:22 À : Menard.Jean-Francois(a)hydro.qc.ca; zope(a)zope.org Objet : Re: [Zope] ODBC DSN file Hi Jean-Francois, I would import the Excel-Sheets into an RDBMS first and then use this to access your data.

RE: [Zope] ZCatalog (2.3.1) won't acquire method from parent fold er?
by sean.upton＠uniontrib.com 14 May '01

14 May '01

A follow-up: After upgrading to 2.3.2, and further investigation, I have found I have a problem, and I have found a workaround. However, what I have discovered is that the problem is not one of acquisition; rather, it is an issue of ZCatalog not cooperating with my DTML methods, residing on disk as part of my Python product. So, in a slightly different light, here is my problem: if I use one of these DTML methods as an index, it has problems evaluating code because it (the Catalog) runs the method, but it will not successfully obtain the namespace of either the object I am trying to catalog / add, or the namespace of the acquisition parent of the newly created - just about to be indexed - object. The implication of this, is that while evaluating the DTML, there is a NameError raised for ANY call to a method within an object of the class you are trying to index; I did not try accessing properties, but I assume that they would suffer the same fate: evaluation of the DTML, being run by the Catalog as an agent, would fail to resolve the namespace of the object for which it is trying to index, and this would mean that any calls to methods/properties of the object from within the DTML would fail with a NameError, raising an exception that breaks any Catalog Aware object attempting to use a DTML method as a text index. My iterateText method resides as a python method BOTH in the class for the object I just added, and the parent folder (a custom class subclassed from OFS.Folder) I am adding the object to. My searchTextWeighted (the method I am indexing) was a DTML method on disk, referenced with searchTextWeighted = Globals.HTMLFile('dtml/searchTextWeighted', globals()) ...I changed this to a python method within the class, and this fixed the problem, but not in the way I necessarily want. What I am hoping to be able to do is create templates that get indexed, so that modifying an existing indexed 'field' does not require directly modifying the class itself, only the DTML methods to which the class refers to. Why won't ZCatalog use the namespace of the object it is attempting to index to run these methods, which belong to the class of those objects? It seems like if it did, there would be no problem doing what I originally set out to do. Is this a bug, or am I going about doing this the wrong way? Any thoughts would be greatly appreciated. For now, I can live with my workaround...

Running Zope 2.3.1; A ZCatalog instance that I have won't acquire a method from the parent folder it resides in; I get a NameError on the method. This is very strange. The method is called from another method whose results are supposed to be indexed. +Zope Root +Classifieds (Container, Subclassed from Folder, contains a method called iterateText(self, text, times)) Catalog (ZCatalog) I have a text index set up for a method called searchTextWeighted, which is a DTML template file on disk within a python product. Inside searchTextWeighted, I have the following DTML: <dtml-var expr="iterateText(getTitleExpanded(), 5)"> iterateText is a method of a python class that is subclassed from ZCatalog.CatalogAware and OFS.Folder.Folder: def iterateText(self, text, times): """Repeats output of text times # of lines for # of times""" result='' times=int(times) for item in range(times): result=result+text+'\n' return result I get a name error for iterateText upon trying to add a catalog-Aware class, when index_objects() is run (I just made this class Catalog-aware). This is weird, since, in terms of namespaces, iterateText is in a folder above the Catalog, and also above the item I am trying to ad, so no matter how you look at it, iterateText should be acquired, and not generate a Name Error. In testing this out, I am able to traverse to iterateText via URL in a browser with no problems. I assume that this is not related to the ZCatalog bug in 2.3.1 where the Catalog won't run a method requiring arguments. The method in the index, searchTextWeighted, passes all the arguments needed by iterateText in the DTML. So I am a bit confused here.

diploma about zope - need help -
by Isabelle Neunreither 14 May '01

14 May '01

hi, I've heard a lot about zope and so I decided to write my diploma about it: "Zope and XML: from studie to the prototype". My major problem at the moment is my inexperience with zope. I can program and work with zope, but I never integrated zope in a real project. The first aim of my study is to understand in which way and situation zope could be recommended for integration and use in companies. You would help me by answering different questions about your experience with zope, as well as about your experience with zope and xml. At the following address under "interviews/about zope", you will find a question form about zope. This form is translated in english, french and german. So I think everyone can answer it :-) http://141.100.43.117:8080/u/isabelle/diploma/zopexml/ Thanks a lot. I hope, I will become a lot of answers. Cheers, Isabelle
