Greetings: I know this has been posted several times but searching both nipltd and activestate archives comes up empty. What I am interested in doing is creating a single pixal border around a table or text block using dtml. Could some one repost the code snippet or provide a short explanation on how to do this with dtml as this neophite wants to exand on his zen...:) Many thanks for any info. -- Chris H The future remains Open......

Using fmt to format
by Peter Bengtsson 30 May '02

30 May '02

This works: <dtml-var amount fmt="%.2f"> But suppose I go: <dtml-let amountformat="'%.2f'"> This doesn't work: <dtml-var amount fmt=amountformat> Nor this: <dtml-var amount fmt="amountformat"> </dtml-let> I just get Error Type: TypeError Error Value: not all arguments converted With a dateobject it's easier thanks to the strftime() method of any date object. What about strings, ints and floats in DTML?? --- Outgoing mail is certified Virus Free.

Problems with ImageFile
by Juan Pablo Romero 30 May '02

30 May '02

Hello I'm trying to create an image using PIL within an external method. I followed the 'makeThumbnail' example, from the Zope book. This is some of the code: ---------------------- import Image, ImageDraw from StringIO import StringIO ... im = Image.new( ... ) ... sf = StringIO() im.save(sf, "JPEG") ... ---------------------- when executed within zope, this code gives an error message, saying something about "...'ImageFile' module has no attribute '_save'..." So I looked for ImageFile, and found that PIL (1.1.3) has his own ImageFile module: Zope-2.5.0-linux2-x86/lib/python2.1/site-packages/PIL/ImageFile.pyc (the one that should be imported within the 'save' method above), but instead, Zope's own ImageFile module gets imported: Zope-2.5.0-linux2-x86/lib/python/ImageFile.pyc What is the proper solution? Regards, Juan Pablo

users can't edit own pages
by Ian McMeans 30 May '02

30 May '02

Hi, I'm getting an odd security issue. I imagine it comes from misconfiguring something, because what is happening isn't the default behavior. I'm using CMF with plone. The issue is that users can't edit their own pages. Each user has a folder in /Members, and the default page that plone (or CMF?) generates for them is in their personal folder. They own that default page as well as their /Members/name folder, but they aren't allowed to modify either. When I log in as a user and try to go into the editing view (at /Members/membername/folder_contents), I get the error: Unauthorized: You are not allowed to access listFolderContents in this context A few lines up the stacktrace, there is: File C:\PROGRA~1\zope250\lib\python\Products\PageTemplates\ZRPythonExpr.py, line 49, in __call__ (Info: here.listFolderContents( contentFilter=filter)) File Python expression "here.listFolderContents( contentFilter=filter)", line 2, in f Now, I can explicity allow them to list folder contents by settings the security permissions (I have to enable listing for everyone in this case). However, this seems to be hiding the real problem, and I don't know what that problem is. Also, I don't want to have to enable every security setting in /Members just to allow the users to modify their personal pages.

File Upload
by Laurie Nason 30 May '02

30 May '02

Hi everyone, I have 2 questions: The lab that I work for will routinely have to upload files via HTTP of between 2MB and 40MB. We will be saving these as External files but this is not the problem. We can upload 2MB files pretty quickly (~3 seconds), but trying to upload an 8MB file takes about 50 seconds. This is true no matter whether I upload the file as an external one or just as a regular File. Therefore I am guessing that the problem comes from Zope's handling of large files and the definite probability that it is loading the file into memory first before saving it. I have seen other people who have had similar problems: http://lists.zope.org/pipermail/zope/2001-July/094581.html http://lists.ozzope.org/pipermail/ozzope/2001-October/000116.html but there don't seem to be any solutions posted. Is there any way of streaming the file into Zope? My second problem comes with the file once it is uploaded - I know that Zope adds a couple of extra properties to an uploaded file, but is there any way I can get at the original file - maybe removing the properties so that I can pass it into another program for processing?

[ANNOUNCE] ArielPartners releases CVSFile 0.8
by Craeg K Strong 30 May '02

30 May '02

This is the second public release of our CVSFile product. http://www.zope.org/Members/arielpartners/CVSFile CVSFile enables Zope content to be served out of files residing in CVS sandboxes, and provides access to common CVS functions through the web in the Zope Management Interface. This new release adds much requested features like * batch add capability -- add instances whole directories at a time! * tunable parameters for CVS commands, and * programmability you may now create instances using scripts rather than through the web GUI if you wish. There are even a set of detailed example scripts to help you get started! Why not simply use ZCVSFolder? Because CVSFile stores files in CVS as normal files, rather than as Python "pickles." This makes it easy to use the same content, held in CVS, in both Zope and non-Zope contexts. CVSFile extends ExternalFile, and therefore inherits all of its functionality. This new release requires ExternalFile version 1.0. This product is compatible with the popular ExternalEditor product. In order to upgrade your existing CVSFile 0.7 objects to version 0.8, you will need to run the repair() method. See the section on Schema Migration in the README.txt file for more details. It is very easy to do. Regards, --Craeg Strong

[ANNOUNCE] ArielPartners releases ExternalFile 1.0
by Craeg K Strong 30 May '02

30 May '02

This is the fourth public release of our ExternalFile product. http://www.zope.org/Members/arielpartners/ExternalFile This new release adds much requested features like * batch add capability -- add instances whole directories at a time! * extensible mimetypes -- you can now add new mimetypes and control exactly how they are to be displayed * can behave_like File -- non-image binaries now behave_like Zope Files, with much improved mime type handling. * programmability you may now create instances using scripts rather than through the web GUI if you wish. There are even a set of detailed example scripts to help you get started! This new release is compatible with CVSFile-0-8. It also extends its "workalike" capabilities. ExternalFile can now behave like any of the following: * DTMLDocument * DTMLMethod * Image * File Why not simply use ExtFile? Because ExternalFile supports pointing to a file "in situ" like a symbolic link, rather than copying it into some central repository directory. This may not seem like a big deal, until you consider that those files might be stored in a revision control system like CVS. ExternalFile gives you the ability to create a Zope object that points to a file in, for example, a CVS sandbox for its content. ExternalFile is usable by itself. It is also the base class for CVSFile. This product is compatible with the popular ExternalEditor product. Objects created using ExternalFile version 0.9 should work with no changes under version 1.0 that is, no special Schema Migration is necessary. Regards, --Craeg Strong

Does anyone know a way to browse the web through a zope server. The idea is to browse from a client appearing as if coming from the zope server machine's ip. Is this a squid/proxy thing? joshua

ZIPFolder
by eric.n.dunn＠bankofamerica.com 30 May '02

Saw a fix issue for "files ignored" problem at: http://zope.nipltd.com/public/lists/zope-archive.nsf/47ba74c812dbc5dd802568… I'm using "ZipFolder 0.2.2" and I still get the "ignored file" problem. Can I add code to the python? If so what should I add so I can upload files with spaces? If not, is is a ZOPE object type thing? Eric Dunn
