manage_addclassname and internal ZClasses
by John R. Daily 13 Mar '01

13 Mar '01

I'm writing an internal ZClass, and I'm having problems with the manage_addclassname function. I modelled it on the classname_add DTML method created by default, and I can't claim that I fully understand what I'm writing, unfortunately. Most of the ZClass documentation, especially with regards to the manage_add* methods, pertains to external Python code. Here's a slimmed-down version of my manage_addFooClass(): --- foo = container.FooClass.createInObjectManager(id, context.REQUEST) foo.manage_changeProperties( { 'title' : 'some title' } ) return foo --- This is invoked by a test script like: --- foo = container.manage_addProduct['Foo'].manage_addFooClass(id) return foo.getId() --- The rub: the new title 'some title' is applied to the container of the new object, not the object itself. According to the documentation I can find on createInObjectManager(), the new object is supposed to be returned, and the other functionality I formerly had in this method seems to back that up. What's going on? Also, does anyone know of any internal ZClasses I can install that are as full-featured as external ones? Also, for subclasses, is it sufficient to define the manage_add* methods alongside the factories for those subclasses? It seems to work, but I've not gotten very far with my testing.

DTML method --> PythonScript
by Timothy Wilson 13 Mar '01

13 Mar '01

Hi everyone, I recently asked what the following DTML Method would look like as a PythonScript. Unfortunately, the answer given doesn't work. I've including the traceback below, and would appreciate any further ideas anyone has. Original SchoolMenuClass_add DTML Method: <HTML> <HEAD><TITLE>Add SchoolMenuClass</TITLE></HEAD> <BODY BGCOLOR="#FFFFFF" LINK="#000099" VLINK="#555555"> <dtml-with "SchoolMenuClass.createInObjectManager(REQUEST['id'], REQUEST)"> <dtml-call "propertysheets.Basic.manage_editProperties(REQUEST)"> <dtml-call reindex_object> </dtml-with> <dtml-if DestinationURL> <dtml-call "RESPONSE.redirect(DestinationURL+'/manage_workspace')"> <dtml-else> <dtml-call "RESPONSE.redirect(URL2+'/manage_workspace')"> </dtml-if> </body></html> The PythonScript that was suggested (with REQUEST and RESPONSE passed in the parameter list): REQUEST = context.REQUEST RESPONSE = REQUEST.RESPONSE schoolmenu = SchoolMenuClass.createInObjectManager(REQUEST['id'], REQUEST) schoolmenu.propertysheets.Basic.manage_editProperties(REQUEST) schoolmenu.reindex_object() if REQUEST.has_key(DestinationURL): return RESPONSE.redirect(DestinationURL+'/manage_workspace') return RESPONSE.redirect(URL2+'/manage_workspace') The resulting traceback:  -Tim -- Tim Wilson | Visit Sibley online: | Check out: Henry Sibley HS | http://www.isd197.k12.mn.us/ | http://www.zope.org/ W.

RE: [Zope] pythonScript huh?

Tom, You can find the api docs under the helpsys system. -Zope Help -API Reference .. .. PythonScript Also, a few notes from experience: 'self' has become 'context' If you define a function, it is only useful inside that PythonScript. You can only import a few modules, per the help page.

RE: [Zope] .html extensions

When I have a need for an extension (ie serving files for download), I tend to do this for a log file: /path/to/logfile?ext=.log IE4 and IE5 will try to guess mime types and if they fail, they look at the extension. The reason for the above notation is to make the object usable in Python, but to help IE figure out what I mean. Troy. I'd like to take this opportunity to thank everyone on the list who helps me with Zope and my many difficulties. Not many mailing lists are this helpful. -----Original Message----- From: Tino Wildenhain [mailto:tino@wildenhain.de] Sent: Tuesday, March 13, 2001 8:10 AM To: Philippe J Cc: zope(a)zope.org Subject: Re: [Zope] .html extensions Hi Philippe, the only reason for .html endings would be for editors to guess the filetype from it.

RE: [Zope] Problem refreshing a python product

Thanks for all the advice. I found the problem with the -D flag. Line 10 in __init__.py was: contructors = ( Should have been: constructors = ( Oops. Thanks for all the suggestions. I'm sure they'll come in handy in the future :) By the way, line 30 in ZProductManager.py didn't exist, though the product said that was the problem.

WebDAV + Dreamweaver
by Carl Blesius 13 Mar '01

13 Mar '01

I just got a response from dreamweaver support concerning the WebDAV problems with Zope!! they put the download to update dreamweaver WebDAV on this page http://www.macromedia.com/support/dreamweaver/ Next step is to get dreamweaver to open Zope files (files without extentions). I have already sent a request to dreamweaver (it would probably help if someone else did the same). Has anybody made progress with this in the meantime? I need a WYSIWYG editor and everyone at my university is already familiar with dreamweaver. Tips/Tricks? Greetings from Heidelberg Germany, Carl

.html extensions
by Chris Cioffi 13 Mar '01

13 Mar '01

Hi all, way back I saw a reference on how to make it look like Zope objects end in '.html'. This can be important for getting into search engines. I've got Apache proxying back to Zope, so I thought that mod_rewrite would be my friend, however Zope still generates URLs w/o the .html. Any help would be great. Thanks. Chris

Help, please.
by Andriy Levytskyy 13 Mar '01

13 Mar '01

To Whom it May Concern: System: Windows NT 4.0; Python 1.5.2 I have downloaded Zope-2_3_0-win32-x86.exe I have installed it as an administartor into "C:\Program Files\Zope"; instalation name is default (I think it is "WebServer"). I choose to start Zope manually. Zope seems to work for administartor. I changed the permitions on the zope folder (and subfolders) to allow 'full control' for my everyday user account "Joe". Now I log in as "Joe". I can start up zope process (via start.bat). I can load the initial screen at http://localhost:8080, but as I go to "Zope Management Interface", the Internet Explorer gives a message: Internet Explorer cannot open the Internet site http://localhost:8080/manage. Invalid argument" I would be greateful, if you can help me with this. With best regards, Andriy Levytskyy

Hello Phillip, thanks for your response. The problem is I've already got a FileUpload instance. (The user is uploading via a form,a bmp or tif) I'm converting(resizing etc.), saving to the filesystem(as tif)and then I'd like to convert to jpeg, return it to Zope and add it to the ZODB. Thanks Sven -- Sent through GMX FreeMail - http://www.gmx.net
