Dear List, clicking on the new External Editor 0.5 symbols in the ZMI of my local zope on win 98 I just get short download window. That's it. Nothing else ... What am I doing wrong? In the explorer I configured the filetype in the open-field like so: "E:\Python22\pythonw.exe" J:\Zope\ZopeExternalEditor\zopeedit.exe "%1" ^ ^ Path to my python 2.2 Installdir of zopeedit-win32-0.5.exe this is my zope specification: Zope Version (Zope 2.5.1 (binary release, python 2.1, win32-x86), python 2.1.3, win32) Python Version 2.1.3 (#35, Apr 8 2002, 17:47:50) [MSC 32 bit (Intel)] System Platform win32 Thanks for your replies, Elena

handling microsoft characters
by Christopher N. Deckard 23 Aug '02

23 Aug '02

Hello, I'm curious as to how some of you handle non-ascii characters which come from Microsoft applications, in particular IE. I've got a system where people can enter text, the text is stored in properties. However, when you actually print out the string, there are non-ascii chars in it. For example, \x92 is the same as a single quote (') character, but in Microsoftese. This just caused a problem for me when trying to build an XML string to pass to a ParsedXML object. I had to create the string as a unicode string (u'') in order for it to work. Should I just always treat things in unicode? Thanks, -Chris

passing variable to dtml method -> sqlmethod
by zopelist＠robertson.net.nz 23 Aug '02

23 Aug '02

Greetings. I have a Z SQL Method that calls a select statement like so: select * from chart where <dtml-sqltest link op=eq type=nb optional multiple> I am calling this from a DTML method that formats the results. I need to call the method several times on a page, passing different values for link. I can send a value from the DTML method to the SQL method, but cannot work out how to send it from the dtml page. Do I have to start writing scripts here? Help appreciated. Don

Zope 2.5.0 and python 2.2.0 on Suse 8.0
by Jan Ulrich Hasecke 23 Aug '02

23 Aug '02

Hi, I have a server with Suse 8.0. The combination of Zope 2.5.0 and python 2.2.0 causes problems with the latest CMFPlone (see http://plone.org/collector/249 ) On my home server with Debian 3.0 (Zope 2.5.1 / python 2.1.3) I have no problems. What shall I do? Would you recommend to upgrade Zope to 2.5.1 and to downgrade python to 2.1.3? And what is the best way to do it on Suse? TIA juh -- Das Handwerk und sein goldener Boden http://www.sudelbuch.de/1999/19991105.html

Can't access a method 'in this context'
by Tim Hicks 23 Aug '02

23 Aug '02

I have a XronDTMLMethod with the following body: ---- <dtml-let zoffice="superValues(['ZOffice Converter'])[0]"> <dtml-call "zoffice.getConverterByName('AsyncZlaveClient').fireNextConversion(_)"> </dtml-let> ---- So, it finds the nearest 'ZOffice Converter' instance (in the acquisition chain), names it 'zoffice', then attempts to do the call in the middle line. My ZOffice class has the following method defined: ---- def getConverterByName(self, converterName): """ """ return self._pluginConverters[converterName].__of__(self) ---- self._pluginConverters is a class level dictionary with keys of converter names and values of converter instances. The converter instances inherit from Acquisition.Implicit. However, when I 'Trigger' the XronDTMLMethod, I get the following error: ---- Traceback (most recent call last): File "D:\Zlave\zope251\lib\python\Products\Xron\XronDTMLMethod.py", line 141, in trigger REQUEST=REQUEST, RESPONSE=RESPONSE, kw=kw) File "D:\Zlave\zope251\lib\python\OFS\DTMLMethod.py", line 127, in __call__ r=apply(HTML.__call__, (self, client, REQUEST), kw) File "D:\Zlave\zope251\lib\python\DocumentTemplate\DT_String.py", line 473, in __call__ try: result = render_blocks(self._v_blocks, md) File "D:\Zlave\zope251\lib\python\DocumentTemplate\DT_Let.py", line 76, in render return render_blocks(self.section, md) File "D:\Zlave\zope251\lib\python\DocumentTemplate\DT_Util.py", line 159, in eval return eval(code, d) File "<string>", line 2, in f File "D:\Zlave\zope251\lib\python\AccessControl\DTML.py", line 29, in guarded_getattr return guarded_getattr(*args) File "D:\Zlave\zope251\lib\python\AccessControl\ZopeGuards.py", line 58, in guarded_getattr return inst.aq_acquire(name, aq_validate, validate) File "D:\Zlave\zope251\lib\python\AccessControl\ZopeGuards.py", line 40, in aq_validate return validate(inst, obj, name, v) File "D:\Zlave\zope251\lib\python\AccessControl\SecurityManager.py", line 83, in validate self._context) File "D:\Zlave\zope251\lib\python\AccessControl\ZopeSecurityPolicy.py", line 145, in validate raise Unauthorized(name, value) Unauthorized: You are not allowed to access fireNextConversion in this context ---- So, my question; why can't I call this method of my converter object? cheers, tim

Zope3 Questions
by Thomas Guettler 23 Aug '02

23 Aug '02

Hi! Here some questions about Zope3: I asked them on the wiki[1] but noone replied 1. What version of ZODB does Zope3X use? 2. Which Python version will be recuired? 3. What changes will be done to the PropertyManager? 4. Will the class Folder store the content in BTree's? (BTreeFolder2) 5. Which changes will be done to ZCatalog? 6. Will the UserManagement be changed so that a role can include another role? 7. What changes will be done to the Permissions? 8. How useable is Zope3? 9. How can I store Properties which should be common to all instances of a class? Yes, there are special Zope3 mailinglist, but I am only subscribed to this one, and I think many others are interested in it, too thomas [1]: http://dev.zope.org/Wikis/DevSite/Projects/ComponentArchitecture/FAQ

Local File System v1.0 released
by jfarr 23 Aug '02

23 Aug '02

Finally, the long awaited next release of the LocalFS product! I've updated it to be a modern Zope product, but the essential guts are still the same rock-solid code that's been in the wild for 3-4 years now. There may still be a couple of new minor bugs, especially doc bugs in the help screens or admin pages. I appreciate any and all feedback, which is now even easier to give, since... LocalFS is now being managed on SourceForge. The LocalFS project page is at: http://sourceforge.net/projects/localfs/ >From here you can download releases, submit bugs or feature requests, or join one of the support forums. Here's what's new (from the change log): - Fixed regex deprecation warning. - Fixed possible IOError on module loadup trying to log exceptions. - Fixed acquisition problems with LocalFile and LocalDirectory objects. DTML rendered from the file system should now work just like DTML in the object database. - Fixed a permissions bug with the manage_upload() method. It was looking for the wrong permission. =( - Updated management pages to new Zope look and feel. - Removed redundant edit page and manage_edit() method. All properties are now edited through the properties page. - Added help system documentation. - Removed automatic text mode translation. All files are now copied as binary (with a nice little performance boost!) - Removed old, crusty win32wnet.pyd. - Changed manage_upload() to use a new strategy for determining the object id from the file path. First we check for Unix path seperators. If we find one we grab everything after the last one as the filename. Next we check for Windows and then Mac path separators and hope we never get a Unix path without a Unix path seperator but with one of these characters ('\' or ':'). Finally, if we never see any kind of path separator we just assume there is no path and use the whole thing as the filename. I think this should work for most browsers. :-/ - Changed object creation protocol. External adapters now receive an open file object instead of a blob of text. - Added get_size() and bobobase_modification_time() methods to LocalFile objects. - Added new manage_createDirectory() method to LocalDirectory objects (uses the 'Manage local files' permission). Big, huge thanks to all the people who have contributed ideas, code, and feature requests over the years. Hopefully it will all pay off when you download the new version! ----------- Also: Right now, I'm putting the wraps on LocalFS v1.1, which is a massive improvement over the current version. Just to give you a sneak preview of the changes: - Handles all major object types out of the box: Image, File, DTML Document / Method, Zope Page Template, Script (Python), ExternalMethod, ZSQL Method, even Database Connections! - Copy and paste from the object database to the file system and vice versa. - Local directories are now represented as Folder objects, so they should behave just like a normal ZODB Folder. - Because of this, object 'data' (e.g., the actual content bits in an image file) is fetched in a lazy manner. This means that the data is not loaded until the object is rendered, but all other object properties are available at all times. Remember, this is just a teaser! These features are not in version 1.0! Sorry, you'll just have to wait another week or two. =) Cheers, --jfarr

Are there any Python-based or Zope-based web mail applications similar to SquirrelMail or Courier's webmail? I need to access Courier via IMAP and POP3. Thanks, // mark -
