July 1999 - Zope - Zope lists

To all Zope mailing list readers

Hello, I'm a new member (been subscribed for three days only), but I have a couple of questions or suggestions: - Wouldn't it be worthwile if people answered even the most silliest questions on the list rather than sending ansers only to personal e-mail? I know I'm having exactly similar problems with others on matters of RH6+Apache authentication, ZQSL/MySQL blob insertion, namespace/namelookup problems, etc that have been asked on this list. I certainly would like to see the answers as well rather than repeat the questions and get the same ansers via e-mail. - If my above idea is bad (it probably increases volume quite a lot and may be a burden for advanced users), then perhaps the people getting personal e-mail answers could summarize the replies in a single list posting, so that others could see the answers too. Anyway, you people have already helped me out on several occasions just by writing on this list. I'm hoping I can learn more from you and eventually contribute something of my own. Best regards, Samu Mielonen PS As a beginner of both Zope and Python, I'm wondering if I should dive into Zope 1.x or 2.x for my learning and development work, esp. if I'm planning to have something up and running on the public web in two months time (wishful thinking, I know :) ? -- "Zone of proximal development - ...the conceptual space or zone between what a [human] is capable of doing on his or her own and what [he/she] can achieve with assistance from ... a more capable peer." - The Penguin Dictionary of Psychology

Treetag bug?
by Andreas Kostyrka 07 Jul '99

07 Jul '99

Hi! I've discovered with Zope 2.0.0a3, that the treetag doesn't create the [+]/[-] urls correctly: It leaves out any ? parameters, which doesn't work to well with SQL queries which need their parameters.

RE: [Zope] Binary data in Zope DTML documents
by Alexander Staubo 07 Jul '99

07 Jul '99

It shouldn't be your tab characters -- I tried adding tabs to a document in Zope 1.11.0pr1, and Zope returned the correct content type. The code to determine whether a document is binary can be found in OFS\content_types.py: find_binary=ts_regex.compile('[\0-\6\177-\277]').search When Zope detects binary data, it returns the content type application/octet-stream rather than text/html. Although as you can see, this won't be triggered by tabs, in my opinion the above regex is way too stringent: This has the unfortunate effect of treating documents with valid, non-binary ISO characters -- including international characters, the Euro, Pound and Yen symbols, TM, and old-style fractions. Sure, HTML character-reference entities can (and should?) be used instead of the actual characters, but that doesn't change the fact that the binary detection is just plain wrong. Btw, you should search your document carefully for the offending characters. Since it's unlikely that the tabs are triggering the problem, there ought to be others. For my own Zope installation I just commented out the binary check, though. In the end, I don't write that many binary DTML documents. :-) Unless anyone has objections, I'll post this to the Collector. -- Alexander Staubo http://www.mop.no/~alex/ "What the hell, he thought, you're only young once, and threw himself out of the window.

Changing tree icon colors
by Jeff Clement 07 Jul '99

07 Jul '99

My site uses the chocolate style sheet from w3.org and as such is fairly dark. I was wondering if there is a way to force the + and - symbols on trees to be a different color (ie. white) Thanks, Jeff 7/5/99 3:54:54 PM [ Jeff Clement / BlueSine Consulting] email: jeff(a)bluesine.tj web: www.bluesine.tj cell: 403.850.9180

Binary data in Zope DTML documents
by Phil Harris 07 Jul '99

07 Jul '99

Hi all, I have a database which has a field called content, this field is mostly text but has a few 'tab' chars in it. It seems that zope then treats this data differently and Netscape then tries to download the file rather tahn render it. IE though renders it correctly! Is it just me or does Zope do this sort of thing, that is, make a distinction when a file has 'binary' data in it. Any ideas? TIA Phil phil(a)philh.org

DTML / HTML and Emacs PSGML Mode
by Alastair Burt 07 Jul '99

07 Jul '99

Dear fellow Zopistas, I wonder if any of you are using Emacs psgml mode to edit DTML and HTML documents for Zope. Maybe you could give me a few tips. I have two questions in particular. They both arise from the fact that psgml only wants to generate syntactically valid sgml code: 1) Is there some trick to get psgml to work with files such as the following?  <h2></h2> <p> This is the  Document. </p>  Really, I want psgml to act as if the file is in an enclosing <body>. From the documentation, it seems that using the variable sgml-parent-document might help, but my attempts to generate such a parent document were not successful. 2) I do not understand how the <dtml-var> syntax fits into the HTML / XMLscheme of things. At first sight, it appears that, if I had a DTD that specified the dtml-var entities etc, then using psgml would be a really easy means to generate files in this syntax. Does such a DTD exist? If not, is it theoretically possible to capture the syntax with a DTD? --- Alastair

hello all, any ideas on why i get an error when i execute the following:  this is coming in from a form, with ENCTYPE set to multipart/form-data, but it throws up an error. Also does anyone know where there is a complete list of all the properties of the REQUEST object? Cheers in advance, Phil. --------------------------------------------------------------------- Phil Grove phil.grove(a)flg21.com Web Development 0113 2949494 flg21 http://www.flg21.com ---------------------------------------------------------------------

Experimental DTML syntax future???
by J Kinsley 07 Jul '99

07 Jul '99

Is the experimental DTML syntax <dtml-foo>&dtml-bar;</dtml-foo> added to DocumentTemplates last month going to be permanent or will it be hosed in the future? I find it preferrable over the standard syntax and would like to use it on a site, but I do not want to have to convert everything back at a future time. Thanks, Jarrod Kinsley

RE: [Zope] Basic ZServer/Zope Question - OBJECT's and Includes
by Alexander Staubo 07 Jul '99

You can easily build your own. Add an External Method that points to this function: import urllib def Include(Url): return urllib.urlopen(Url).read() Then, assuming you called the External Method "Include", call it up like so:  Simple. You can do more complex stuff with httplib if you need it. -- Alexander Staubo http://www.mop.no/~alex/ "What the hell, he thought, you're only young once, and threw himself out of the window.
