PHP Document file not found
by Ulrich Wisser 27 Feb '02

Hello, we try to produce jpg pictures from a PHP Document. It works fine, generaly speaking, but sometimes it fails: Error Type: IOError Error Value: [Errno 2] No such file or directory: '/tmp/1014800341_1.out' How can that happen? When there is an error in PHP it still writes to the .out file, it just doesn't display any picture. But here the whole output is missing. Any ideas?

product for simple editing (no HTML)
by Miles Fidelman 27 Feb '02

27 Feb '02

Hi Folks, I'm considering using Zope to set up a site for a small organization. What I'd like to be able to do is delegage management of specific pages, or sections within pages, to individuals who do not have HTML skills. So.. I'm looking for something that works within the Zope environment, where a designated individual: - goes to a specified URL - logs in - enters ascii text - hits save - sees a preview - hits submit to send the change to somebody for approval Nice additions would be: - a simple way to insert paragraph breaks - some basic WYSIWYG editing Can somebody point me at such a beast? Thanks much, Miles Fidelman ************************************************************************** Network Technology Corporation PO Box 600618 Miles R.

Forcing someone to download a .html file
by Peter Bengtsson 27 Feb '02

27 Feb '02

I have a little method in my product class that when called returns an XML file and Internet Explorer asks if you want to Open it or Save it. That's almost what I want and it working in IE(5or6) is only important. It's just one windows user who will need this. What I want ultimatly is that when editing "foo.html" in the ZMI there will be the option of downloading it "Click to download foo.html". Clicking that will automatically show the little Save/Open dialog for download. Ideally Here's the code:: def Download(self, REQUEST, RESPONSE): """ Download the document source and PUT it forward """ doc_src = self.document_src(REQUEST, RESPONSE) from whrandom import random id = "File"+ `random()*10`[2:4] suffix = 'xml' f=StringIO() f.write(doc_src+'\n') RESPONSE.setHeader('Content-type','application/data') RESPONSE.setHeader('Content-Disposition', 'inline;filename=%s.%s' % (id, suffix)) return f.getvalue() That works fine but I don't want to save it as .xml because that makes it difficult to open in Dreamweaver. Using 'html' for the suffix makes IE trying to open it immediatly. Desperate for some helpful advice or hints. Peter

Re: [Jython-users] Jython and Zope

I'm new to Python > so go easy on me. :) As far as I know (and I've been looking -- still am), there's no direct support for Jython in Zope. However, Jython is strictly a *client-side* technology and Zope is strictly *server-side* -- so in principle, there isn't much overlap. You could use DTML Methods/ Documents and File objects to hold the Jython code and the interpreter. What would be kind of cool, though, is a Zope product to encapsulate a Jython applet as a Zope object. I think it ought to: 1) Provide a syntax-sensitive editing interface (can we just use the one currently provided for Python scripts? I'm not sure if the syntax is similar enough. I mean -- is the syntax checker aware of standard modules (which may differ) or just legal Python syntax (which should be the same)? Actually, it occurs to me that this may not really be a "syntax checker" -- is it actually just importing the module and reporting the traceback from that? In which case, this is really the same as #3 below. 2) Automatically provide the wrapper code to deliver the Jython interpreter applet and generate the correct <applet> tags, etc. This would be akin to what Zope does for images. 3) It might be good to actually pre-compile into a .jar file (or whatever is appropriate -- I'm a Java/Jython newbie, so go easy on _me_ too ;) ), on the server. Probably one should do this whenever the program is edited on the server, and report errors/traceback from the program. This probably has to be done from an unrestricted Python module (which may in turn call other programs on the server, such as jythonc), so that means putting it in as an External method, or (better) including it in a Zope Product. With Jython, there's an obvious cache-optimization problem -- you want to make sure you only download the core/interpreter part once, and the applets separately. You also want to avoid triggering various security problems with client-side code, which seem to happen when you evaluate/execute strings inside of Python. This probably ought to be done on the server if it can't be avoided (?). It seems to me that there's enough repetitive work here to justify making a special product to simplify it. If you had this, I think you could just edit a Jython client-side method in Zope, save it (which would compile and store on the server), and then embed it into a DTML document, using <dtml-var myJythonObject>. I was thinking of waiting until the O'Reilly book on Jython comes out (I'm not experienced at Java, so I don't think the other book is going to help me so much), and then having a go at writing such a product myself, since I want to do a fairly large amount of Jython stuff with Zope. My attraction to this is the beauty of having both server and client programmed in the same programming language (Python), instead of having to learn and interface between two different ones. This would also reduce the burden of deciding where to draw the line between server- and client-side components, since they would then be relatively easy to port back and forth. So ... Has anyone already done this (and I'm just not so good at finding it), or is anyone interested in collaborating / discussing this with me?

hi, i heard about "manage_change_history" is there someone who can tell me how i could create a list of all history versions of a dtml document ? like dtml-in manage_change_history version number user date content of DTML Document /dtml-in I already use <dtml-if manage_change_history> <dtml-in manage_change_history mapping> <dtml-if sequence-start> <dtml-var user_name> </dtml-if> </dtml-in> </dtml-if> but this gives me only "one" user_name back :-(
