As you start to simplify too much, being able to use and re-use something in different situations becomes very difficult. On the other hand, if you make things too general, they become too hard to use. :/ > So since I'm a glutton for punishment, why wouldn't a tag: > >  But then you lose control over things like borders, javascript event handlers, imagemaps, style sheet properties, and all of the billions of combinations of tags. If you're doing a graphic intensive site, I would imagine that you would want finer control over your images and to be able to take advantage of HTML that Zope-Image developers can't keep up with. WebObjects is engineered for these types of dynamic widgets, Zope (like ActiveServerPages) isn't. So while you don't get a single-line #var insert, you do get tight control when you need it. For example, I've tried a few times to come up with a SELECT list tag that would select a value already given by the user. Sounds simple, right? Not with the flexibility I've often found myself yearning for (having to compare a possibly set value against one or two other lists coming from multiple sources and setting the presentation value and the widget value). The only major widget we have is the tree tag. And, while it brings incredible simplicity to generating hierarchical "tree" objects in HTML, there have been many times where it's grown with new parameters and more new parameters and even more new parameters to cover more and more of the different ways Trees needed to be rendered. Again, this is a fairly general-purpose widget. Specific widgets like images or select tags are tips of very very big icebergs.

- Updated win32 PYD files
by David Ascher 07 Dec '98

I've added the cPickleCache.pyd file to the unofficial win32 patches located at: http://www.zope.org/Download/Contrib --david ascher PS: I'd suggest to email me w/ win32-specific bug reports due to the use of said patch, instead of the main list (after all, Zope isn't supposed to work on Win32 yet =)

I understand I'm looking for an easy solution, BUT... for example, in Frontier, yo ucan type something like: #image "blah.gif" And it will insert everything needed (including H/W tags). This works even if you happen to have things stored in a subdirectory if I recall (it's been a while). I know that most sites Zope has been used for probably aren't that graphically intense, but a lot that I work on are, and I'd be stuck with nearly a billion of these refernces or writing custom code that probably is identical to other people's custom code. For the object repository to be useful, it has to be able to SIMPLIFY my life, not complicate it :-) So since I'm a glutton for punishment, why wouldn't a tag:  Be allwoed to insert it's location in full, rathre than relative (which should never break anything I can thinik off off-hand), as well as it's ALT and H/W tags (which maybe should be stored in properties now that I think about it, and only updated when the image is inserted into the database/updated, lower overhead).

When you have Documents calling Documents its sometimes hard to keep things straight. Acquisition is part of the confusion, but I don't really think its the issue here. Basically you have an object docA calling another docB. The docB is told to execute a method that both it and docA implement. So it calls its own method. Really you would like to specify that it should call the method on DocA. This is hard to do, if you just specify the method name. I propose that there should be something analogous to the PARENTS list for Documents. Maybe is should be called CALLERS or DOCUMENTS or something. It should be a list of Documents, so that when index_html calls standard_html_header which calls mydoc, mydoc should be able do something like:  To call a method on index_html (the first CALLER). Thoughts? -Amos P.S. This facility would make the view dtml source widget on the Zope site work, as well :-)

It can be relative or absolute, just as with a normal html document. Maybe I'm missing the point... > Should I stop beating myself over the head yet? Yes, and help me write the Multi-Part Document Product, part of which was intended to help solve associated problems (and a shot at anchor cross-referencing in general also. :^) Kent.

PDF and Zope
by Oscar Picasso 05 Nov '98

05 Nov '98

Hi, I need to modify on the fly PDF file that are stored in a ZODB. The basic idea is to use these PDF files as templates and add to them some texts and drawings generated by some external method or with DTML scripts. I tried Pavlos ZpdfDocument product. It's very nice to generate PDF code from HTML or Structured text. However I need something more flexible. I took a look also at the PDFGen library. I think it could meet some of my requirements, especially the Canvas methods are very useful and easy. But here too it seems that you can only produce new PDF documents. As anyone tried to do the same thing (adding objects to PDF files)? Any pointer greatly appreciated. ****************************************************** Oscar Picasso picasso(a)videotron.ca ******************************************************

Newbie question: Unhandled requests.
by Hannes 10 Mar '97

10 Mar '97

We currently started to run our site using Zope behind Apache using ProxyPass, when testing from the outside it seems that there many (about one-third) of the requests that are not handled by Zope, the browser seems to recieve nothing, (means the browser times out), this behaviour does not depend on the complexity of the document templates, it is an overall phenomenon (including management screens etc...). When pressing reload the things get okay most of the times, but it is annoying.. Any help would be appreciated..... thanks in advance. H.Grund. please replay to grundhan(a)cs.tu-berlin.de
