problems with ftp and 2.3.0
by Oliver Frommel 16 Feb '01

16 Feb '01

Hello, there seems to be a problem with FTP in Zope 2.3.0 (on Linux Redhat 6.0). I can list the contents of the root dir (however the Zope console shows an error "PROBLEM(100) ZServer unhandled connect event"). If I want to change to certain subdirs I get "550 No such directory", if I try to list their contents the error message is "550 Could not list directory". These subdirs are just regular Folders but one of them contains custom ZClass instances while the other contains DTML Documents/Methods, Images, External Methods, a User DB, a Catalog, a MailHost and a MySQL DB Conn and a LocalFS (already patched) so i guess it _should_ be listable, right? Of course both Folders are listable in the HTML management interface. Other Folders in the root dir are listable too. Any idea what's wrong or how to debug the problem? Thanks --Oliver

Hi, Is it possible to do that? I'm thinking of a wizard to help people to build ZClasses. Cheers Dirksen __________________________________________________ Do You Yahoo!? Get personalized email addresses from Yahoo! Mail - only $35 a year! http://personal.mail.yahoo.com/

Re: [Zope] performance problem

Hallo, Unfortunatly this doesn't solve the problem, ...thanks anyway. After a view of a site which contains a URL + size of a pdf-doc(4MB), the memory usage of the process grows up to 4 MB more. I think ZOPE loads all object attributes (including data) to it's cache. So, if a searchengine spiders my site everything goes into the cache. I changed to store the docs in the LocalFS-Prod. to disable this caching behaviour :-( . I know there where some threads about caching and performance in this discussion-group but I cant find a solution for me. Is there a way to disable caching for products/attributes/objects ? I think this would be nice for some sites which have not too much requests but a large amount of data. Hope you can understand my english, thanks for any suggestions, Torsten. > Author: Torsten Gallmeister > Date: 01:19 PM Yesterday > > >hello, > > >could anybody help? > >Have a perforemance prob.

No Searchable Objects!

Hi; I can't make searchable objects! I either get an HTTP 500 error or I get >>> No searchable objects Traceback (innermost last): File /apache/Zope-2.2.4-linux2-x86/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /apache/Zope-2.2.4-linux2-x86/lib/python/ZPublisher/Publish.py, line 187, in publish File /apache/Zope-2.2.4-linux2-x86/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook File /apache/Zope-2.2.4-linux2-x86/lib/python/ZPublisher/Publish.py, line 171, in publish File /apache/Zope-2.2.4-linux2-x86/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: manage_addZSearch) File /apache/Zope-2.2.4-linux2-x86/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: manage_addZSearch) File /apache/Zope-2.2.4-linux2-x86/lib/python/Shared/DC/ZRDB/Search.py, line 100, in manage_addZSearch ValueError: (see above) <<< Wazzup?

content-type (was Re: export to excel)

> Here's some crude code to do what you want. Note that some lines are > broken by my emailer and excel may be picky about extra white space. > > yourMethodName.csv: > > Content-type: application/ms-excel <snip> Hi, I've developed some import/export functions myself taking database info to/from CSV and/or tab delimited text files. Originally, I just displayed the output to the user directly (in text form) but as I've seen from the past few messages, I can have it displayed directly in Excel. I have had success with this in IE but Netscape is giving me "jip"... Simplified version below: Id: exportDirectlyToExcel.csv Title: exportDirectlyToExcel.csv -+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ <dtml-in get_matrics_from> <dtml-var expr="export(_.this, classcode, matric)"> </dtml-in> -+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ When I open this document in IE it opens Excel automatically but it only opens the text representation when I open it Netscape. I presume that adding a content-type would remedy this but where and how do I add it? "Content-type: application/ms-excel" at the head of the page doesn't help. Including it in <HEAD><META> tags isn't helping either. Can anyone tell me the solution? Here's a sample output... 9728430, Lee, Reilly, lreilly, 8, 2, 0, 0, 0, 0, 0, 0, 0, *, *, 0, 0 9702709, Gordon, Macleod, gmacleod, 25, 0, 3, 0, 0, 0, 0, 0, 0, *, *, 0, 0 9702075, Alan, Hamilton, ahamilto, 7, 0, 0, 4, 0, 0, 0, 0, 0, *, *, 0, 0 9712346, Alec, Littlechild, alittlec, 5, 0, 0, 0, 5, 0, 0, 0, 0, *, *, 0, 0 9712347, Fernando, Ricksen, fricksen, 8, 0, 0, 0, 0, 6, 0, 0, 0, *, *, 0, 2 9712349, Arthur, Numan, anuman, 3, 0, 0, 0, 0, 0, 7, 0, 0, *, *, 0, 2 9712351, Chris, Sutton, csutton, 10, 0, 0, 0, 0, 0, 0, 8, 0, *, *, 0, 2 9712352, Claudio, Cannigia, ccannigi, 12, 0, 0, 0, 0, 0, 0, 0, 9, *, *, 1, 0 9712350, Henrik, Larsson, hlarsson, 9, 0, 0, 0, 0, 0, 0, 0, 0, *, *, 0, 0 What can I add to this to make Netscape realise it's an Excel file and open in accordingly?

RE: [Zope] ZClasses and automatic sub-objects
by Farrell, Troy 15 Feb '01

Yes, it is possible. I do it all day. My lines in the constructor are as follows: <dtml-call expr="propertysheets.StreamingEventProperties.manage_editProperties(REQUEST) "> <dtml-call expr="manage_addProduct['OFSP'].manage_addFolder('logs', 'Log Files')"> <dtml-call expr="manage_addProduct['OFSP'].manage_addFolder('analysis', 'Log File Analysis')"> If I may, I'll piggyback on your question. I have an ObjectManager derived ZClass. It has a folder 'logs' as above. Is it possible to Catalog the contents ('data') of a DTML method contained therein? -----Original Message----- From: Tim Moore [mailto:tmoore@tembel.org] Sent: Thursday, February 15, 2001 4:17 PM To: zope(a)zope.org Subject: [Zope] ZClasses and automatic sub-objects I have an ObjectManager-derived ZClass. I would like all instances of this ZClass to have a subobject added to them automatically at creation time. This subobject has a fixed id in each instance (in this case, I want to add Image objects with an id of "logo"). Preferably, this object would a permanent part of each instance...you wouldn't be able to delete or rename it in any instance, but you would be able to edit it (e.g., upload image data). So, essentially it would act analogously to a property sheet. Is this even possible? I asked this question a couple of weeks ago and never got a response. -- Tim Moore _______________________________________________ Zope maillist - Zope(a)zope.org http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

Zope will not see the '.'. It is inside a Python string. > the last because i don't find the an example how to use find right. "find" returns the index, the string is found at; "-1" if the string is not found. Thus, you want something like "find(...) >= 0". Be careful, however! It is not garanteed that "error_value" will be a string (in general). It might well be an instance, then "find" will raise a "TypeError". Dieter
