Don't need answers like "but gopher is old, ugly, etc", "we > will loose all fomatting, etc", etc. ZServer (aka medusa) is protocol agnostic; I would look at the Request/Responses there, plus their equivalents in lib/python/ZPublisher, and try to fold in Python's gopherlib module with them (check out ZServer/medusa/http_server.py, as well). > Thanks, > > /dario :)) > > read all about it: > gopher://gopher.heatdeath.org/00/the%20gopher%20manifesto.txt Tres. -- =============================================================== Tres Seaver tseaver(a)digicool.com Digital Creations "Zope Dealers" http://www.zope.org

What version of Python Methods - no - Scripts for 2.2.4?
by Ronald L. Roeber 14 Dec '00

14 Dec '00

Quesrion(s): Is the recommended install of Python Scripts for Zope 2.24 this? http://www.zope.org/Members/4am/PythonMethod even though it appears to be exactly one year old today (13-Dec)? This is also the date in the CHANGES.txt file in 2.3_a1 PythonScripts directory. Can I just copy the PythonScripts product from my 2.3_a1 Products directory to the appropriate location on a 2.24 server or should I use the PythonMethod from above? Are there implications for upgrades from Methods to Scripts? Am I missing something(s)? (probably) Please advise. Sorry to be so confused. Thank you. ron...

Sorry for the late reply, I don't check this list until after work. If you have X windows and you have fonts in the bdf or pcf format you can use the script that comes with PIL called pilfont.py to create fonts. Also, I took a few of my fonts, formatted them, zipped em up, and put them in my zope.org member folder. <a href="http://www.zope.org/Members/byron/fonts.tar.gz">http://www.zope.org/Members/byron/fonts.tar.gz</a> hope this helps.

Object adding strangeness
by Geoffrey L. Wright 14 Dec '00

14 Dec '00

So I've created a simple little product to dynamically manage CSS. It consists of three ZClasses and the arrangement looks something like this: STYLEn_containerClass \ \--> STYLEn_styleClass \ \--> STYLEn_stylePropertyClass The STYLEn_containerClass can contain a variable number of styles which can, in turn, contain a variable number of properties. I've also hacked the add method for the STYLEn_containerClass so that it creates a number of default styles. So far, this has all worked swimmingly, but I have run into one really strange issue that I can't figure out for the life of me. Basicly, the folder that contains the STYLEn_containerClass somehow(?) manages to aquire the title of the last instance of STYLEn_styleClass that gets created. So in the follow example, the title of the containing folder get renamed to "Header style" from whatever it happened to be before. Does anybody have an idea of why this might be happening? TIA for any answers or leads. My code is below: --- <dtml-comment>Create the "STYLEn" container.</dtml-comment> <dtml-with "STYLEn_containerClass.createInObjectManager('STYLEn',REQUEST)"> <dtml-call "propertysheets.STYLEn_containerClassPropertySheet.manage_editProperties(REQUEST)"> <dtml-call "manage_editProperties(REQUEST)"> <dtml-comment>Create header style</dtml-comment> <dtml-call "REQUEST.set('ts', ZopeTime())"> <dtml-call "REQUEST.set('id',_.str(_.int(ts)) + '-1')"> <dtml-call "REQUEST.set('title','Header style')"> <dtml-with "STYLEn_styleClass.createInObjectManager(REQUEST['id'], REQUEST)"> <dtml-call "REQUEST.set('element','h1')"> <dtml-call "REQUEST.set('style','header')"> <dtml-call "propertysheets.STYLEn_styleClassPropertySheet.manage_editProperties(REQUEST)"> <dtml-call "manage_editProperties(REQUEST)"> <dtml-with "STYLEn_stylePropertyClass.createInObjectManager('font-family', REQUEST)"> <dtml-call "REQUEST.set('value','arial, sans-serif')"> <dtml-call "propertysheets.STYLEn_stylePropertyClassPropertySheet.manage_editProperties(REQUEST)"> <dtml-call "manage_editProperties(REQUEST)"> </dtml-with> <dtml-with "STYLEn_stylePropertyClass.createInObjectManager('font-size', REQUEST)"> <dtml-call "REQUEST.set('value','16pt')"> <dtml-call "propertysheets.STYLEn_stylePropertyClassPropertySheet.manage_editProperties(REQUEST)"> <dtml-call "manage_editProperties(REQUEST)"> </dtml-with> <dtml-with "STYLEn_stylePropertyClass.createInObjectManager('font-style', REQUEST)"> <dtml-call "REQUEST.set('value','normal')"> <dtml-call "propertysheets.STYLEn_stylePropertyClassPropertySheet.manage_editProperties(REQUEST)"> <dtml-call "manage_editProperties(REQUEST)"> </dtml-with> <dtml-with "STYLEn_stylePropertyClass.createInObjectManager('font-weight', REQUEST)"> <dtml-call "REQUEST.set('value','bold')"> <dtml-call "propertysheets.STYLEn_stylePropertyClassPropertySheet.manage_editProperties(REQUEST)"> <dtml-call "manage_editProperties(REQUEST)"> </dtml-with> <dtml-with "STYLEn_stylePropertyClass.createInObjectManager('color', REQUEST)"> <dtml-call "REQUEST.set('value','#000000')"> <dtml-call "propertysheets.STYLEn_stylePropertyClassPropertySheet.manage_editProperties(REQUEST)"> <dtml-call "manage_editProperties(REQUEST)"> </dtml-with> </dtml-with> </dtml-with> <dtml-comment> Now we need to return something.

stupid file upload question
by Joh Johannsen 14 Dec '00

14 Dec '00

OK, there is a How-To on that, which is helpful, by benno But it says: "In you python external method you can now reference REQUEST.form['attached_file'] as a normal file. You can perform things such as read() on the object. " Now in my Python external method, I can reference things like: REQUEST.form['attached_file'].filename and that is fine. But what is the syntax for actually reading the file? From the above quote I thought it was as simple as x=REQUEST.form['attached_file'].read() but that doesn't work... Either that or some way to get at the name of the file on the server. The above 'filename' is just giving me the name of the file on the client side, I have no idea where it is on the server. Thanks, JJ

Lost with navigation using objectValues
by Stephane Bortzmeyer 13 Dec '00

I just try to automatically get a list of subfolders, following the example in the ZopeBook <http://www.zope.org/Members/michel/ZB/SimpleExamples.html>. Here is my code, in a DTML method in the root folder: <ul> <dtml-in expr="objectValues('Folder')"> <li><a href="<dtml-var absolute_url>"> <dtml-var title_or_id></a></li> </dtml-in> </ul> If I call it from /index_html, it works fine. If I call it from any other document anywhere, I just get <ul></ul> (so I'm sure the method has been called) but nothing else as if objectValues sent nothing (no need to say that I *have* subfolders an I also tried without the 'Folder' restriction, with the same result). Any advice? Zope RPM 2.2.2 on RedHat 6.2.

After much playing around I determined that the problem was Python 2.0. I downgraded zope to 2.2.4 and still had the identical problem with python 2.0. Then when I downgraded python to 1.5.2 the problem finally went away.

This is a Python feature: If both arguments are integers, the division is performed as an integer division. Use "3.0/2" or "3/2.0" or "float(3)/2" to get a floating point division. Dieter
