RE: [Zope] Newbie Q: Error creating LocalFS

I'm getting something similar. Horrible errors with Python 2.3.3/Zope 2.7/latest LocalFS & LocalFS_Patched on a Linux system with 2.6 kernel, gcc 3.3.3, etc. I don't have this problem on As soon as I install a LocalFS object within a Zope folder, the folder becomes inaccessible. It generates some sort of gibberish error, and the error log indicates a "Not Found" error type. I can't access the folder through the management interface, but have to use the manage_UndoForm URL extension to get into the folder and undo the installation of the LocalFS object. Just tried this on my Win32 machine, with the same error - ============================ Site Error An error was encountered while publishing this resource. Resource not found Sorry, the requested resource does not exist. Check the URL and try again. Resource: sequence-odd Troubleshooting Suggestions * The URL may be incorrect. * The parameters passed to this resource may be incorrect. * A resource that this resource relies on may be encountering an error. For more detailed information about the error, please refer to error log. If the error persists please contact the site maintainer. Thank you for your patience. ============================ SOLUTION: perhaps - Did a search on this issue, saw http://www.my-zope.org/Members/kedai/News_Item.2003-12-30.2242 Tried LocalFS 1.1 and it seems to work on my Win32 machine. Don't have access to the Linux box so can't comment. Now the problem I'm having is that when I specify path as "." (ie, current directory) LocalFS doesn't map it to the $INSTANCE/var directory any longer. This is a bother, since all my previous path definition have been relative. Any way to fix this? Think I'll post it as a separate question on the list.

I wonder if anyone can shed any light on this, or point me in a different direction. I am really new to Zope, so forgive me if I'm doing something really obvious, or perhaps impossible. I want to use ZServer as a DAV server to my users' OS filestores (/home/user - FreeBSD 5.2). In the root of my Zope (2.7) I add a folder called dav, and I point my virtualhostmonster at it as 'dav.domain.com/dav/' (but I'm not getting this far so that shouldn't matter). Then in the dav folder I create a Local File System object (downloaded today from http://zope.org/Members/SmileyChris/LocalFS_Patched/0.3) called 'username' with a base of '/home/username/dav/' (a directory I just created and gave my Zserver process user ownership of). And when I click 'Add', it all goes horribly wrong and I get the error: "Site Error An error was encountered while publishing this resource. Resource not found Sorry, the requested resource does not exist. Check the URL and try again.

And from then on whenever I try to access the dav folder from the root I get a similar error. (Note, I tried adding the self.isAnObjectManager=1 test as detailed in a post of Thu Jan 8 12:26:24 EST 2004 to this list, but unless I have missed some step in editing a .py file, it hasn't had any effect) Help!!!

I have trivial class: <file MyClass.py>: from OFS import SimpleItem from Globals import DTMLFile def manage_addMyClass(self, id, REQUEST): "add" a=MyClass(id) self._setObject(id,a) if REQUEST: return self.manage_main(self, REQUEST) manage_addMyClassForm=DTMLFile('dtml\manage_addMyClassForm',globals()) class MyClass(SimpleItem.SimpleItem): "minimal object" meta_type='MyClass' def __init__(self, id): "init" self.id=id I can add objects of MyClass through ZMI. How can I add some object through my own interface: for example, on button click on DTML form? Regards, Serg.

database transaction problem
by martin f krafft 17 Mar '04

17 Mar '04

I am experiencing a problem with my Zope application, interfacing with PostgreSQL through PsycopDA. The problem is basically that a python script creates a new record in a database table, which is used by exUserFolder as a backend for authentication (thus containing the list of all users). When this completes, the script calls another script which tries to change ownership of a ZoDB object to the newly created user, which fails because "Only users in this site can be made owners." I think the problem is rooted in the fact that python scripts work on databases in transaction batches, and as the script has not finished, the transaction adding the user has not been committed. Other than issuing a manual COMMIT, how can I make sure that exUserFolder sees the changes made to a database while the script is still executing?

LocalFS Issues
by Samir Mishra 16 Mar '04

16 Mar '04

Apart from another issue I've been having with LocalFS, which I think I may have fixed by upgrading LocalFS to ver. 1.1, I'm experiencing other unexpected behaviour. When I add a LocalFS object and specify the path as "." (ie, current directory), LocalFS doesn't map it to the $INSTANCE/var directory any longer, and neither does it map it to $ZOPE. It's mapped to ..\$ZOPE. This doesn't seem safe either. It's a bother since I've always used relative paths for LocalFS. And when I try and edit (and only on edit) the path on an already existing LocalFS object from the Properties tab, I get the following error - =============== Site Error An error was encountered while publishing this resource. Error Type: AttributeError Error Value: _fs_read Troubleshooting Suggestions * The URL may be incorrect. * The parameters passed to this resource may be incorrect. * A resource that this resource relies on may be encountering an error. For more detailed information about the error, please refer to the error log. If the error persists please contact the site maintainer. Thank you for your patience. =============== Any way to fix this? Using Python 2.3.3/Zope 2.7/LocalFS 1.1 Thanks. Samir

RE: [Zope] LocalFS 1.2-andreas released
by Samir Mishra 16 Mar '04

16 Mar '04

I'm having a lot of problems with generic LocalFS/Python 2.3.3/Zope 2.7 and just installed your version. It seems to be OK, except that in the folder view, all the files in the directory show up twice, once with the real filename, and then again in a .FILENAME,z format, and with a size of 1K. Clicking on the second pseudo-file gives me a Zope object listing (as below) that looks like a cpickle object. Am I doing something wrong? Also, if using "." as path, the LocalFS maps to $ZOPE directory, I believe it should map to $INSTANCE/var (or $CLIENT_HOME). Files I upload don't have corresponding pseudo-files. Deleting the .FILENAME,z "files" (or object) does not seem to break anything and they don't reappear. Is this behaviour unique to my installation? Thanks.

RE: [Zope] classes in external methods

Try the template below for your classes. You can create objects of classes you write like this and return them via external methods to ZPTs and Scripts inside of Zope. from AccessControl import ClassSecurityInfo from OFS.ObjectManager import ObjectManager import Globals class Class1(ObjectManager): security = ClassSecurityInfo() def __init__(self): pass security.declarePublic('Func1') def Func1(self): return self.somedata Globals.InitializeClass(Class1) -----Original Message----- From: nwingfield(a)dixon-hughes.com [mailto:nwingfield@dixon-hughes.com] Sent: Wednesday, 17 March 2004 8:44 AM To: zope(a)zope.org Subject: [Zope] classes in external methods Since Zope's Python Scripts will not allow me to import the csv module, I wrote my own little class within an External Method. My class opens a CSV file and returns a dictionary representation of each line, one at a time. Now Zope pops up an authentication dialog when I try to call my External Method. Is there some way around this? Can someone also explain why Zope does this? I thought an External Methods was a failsafe way to write unrestricted Zope code without going all out and writing a product (which just doesn't make sense in this instance). Nathaniel

How to import CSV into SQL (gadfly)?
by Jaroslav Lukesh 16 Mar '04

16 Mar '04

Hi all, I have three CSV tables (together 120k) and I need import that data into some SQL database for different kind of views to data strored in tables. Because Gadfly is enough for that amount of data and I does not have installed any other SQL at production machine, I want to import CSV into gadfly. I was search over net, but does not find something usefull. Or it is possible to use TinyTables or something similar with power of SQL commands for that table structure? CREATE TABLE katalog ( poradi integer, kod_dest varchar, ... ) CREATE TABLE dest ( kod_dest varchar, ... ) CREATE TABLE pok ( poradi integer, kod_dest varchar, ... ) Do you have somebody experience or tips how to do that? Many thanks, -- Jaroslav Lukesh

Re: Ape and DBTab Configuration in Zope 2.7

>>you can try getting Ape from zope's cvs repository. Last time >>I did a checkout the cvs version was working with zope 2.7.

It always says > something is in the way when I add a ZODBMountPoint. > All the doks are not for zope 2.7, so I don't know what's wrong. > Some hints how to use ape for zope 2.7 would be great. If it's saying that something is in the way I think you already have an object on the mount path. (i.e. if you are trying to mount the ape storage at /fs, you can't have an object or folder already named "fs" at your zodb root.) So if you already have something named "fs", rename it, add the mount point, and then copy items from your renamed "fs" folder to the new folder. You might want to get a cvs checkout from Feb 1, 2004 as well. As far as I can tell that has the Python 2.3 fixes, but it's before Shane started adding changes for 0.8. I'm not sure how stable the cvs HEAD is right now. I can't really think of any general hints, but if you can post specific errors and questions to the list, people are generally willing to help :) Unfortunately, I think a lot of the Ape discussion has happened in private email, so it's been a lot of trial and error for me to get things working. Hopefully this thread helps the situation a bit. joseph
