Where do we have to inherit from when writing a persistent object? As I have seen, there are at least two choices: Persistence.Persistent and Globals.Persistent Thanks, Mario. _________________________________________________________________ Send and receive Hotmail on your mobile device: http://mobile.msn.com

I'm a Zope Newbie. How do I determine the type of an object instance, so that I can distinguish between Folders and other types of object? Elliot --- Outgoing mail is certified Virus Free.

Re: [Zope] mailhost problem

The header handling in MailHost is broken. 2.6 will include a fix for that, which is more or less what you get in the enclosed patch. I would be great if you tried it out to see if it works better, Best regards Lennart Regebro, Torped http://www.easypublisher.com/ ----- Original Message ----- From: "Drew Nichols" <drew(a)mena.org.au> > Using mailhost.send ('message', 'to(a)email.com', 'from(a)email.net', > 'subject', 'anyEncoding') > screws up the mail headers by putting 'message' in between subject: and > content-transfer-encoding: > > is it just me?? > > using qmail on rh linux >

RE: [Zope] Accessing self in External Methods
by sean.upton＠uniontrib.com 02 Sep '02

02 Sep '02

When you say the file object is an attribute of your ZClass, what do you mean. What superclasses are you using? Are you getting a NameError? For your last question, have you tried getting self.__class__ in your external method to access the class; I don't know if this will accomplish what you are looking to do, but it seems worth a try? Sean -----Original Message----- From: ratem(a)censa.com.br [mailto:ratem@censa.com.br] Sent: Friday, August 30, 2002 10:28 AM To: zope(a)zope.org Subject: [Zope] Accessing self in External Methods Hi, I am using an external method to call wvWare and catalog a M$-Word file content. The file object is an attribute of my ZClass. The external method is called by a Python Script (PrincipiaSearchSource). I´d like to know how can I access the file atribute from the external method. I tryed directly: self.file, but it didn´t work. Does that mean ZClasses atributes are always private? How can I get this file object? Using getattr? One more question: how can I modify a class attribute inside the External Method? thanks, Rogerio _______________________________________________ Zope maillist - Zope(a)zope.org http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

Image handling
by Andreas Tille 02 Sep '02

02 Sep '02

Hello, I have to present a colored map accord to some database values. The values define a certain color for some reasons of the map. (Example: Assume a map of the world and color each country according to the density of people in this country.) My idea was to use an XPM graphic which has a quite simple text format and just define the color to display for each region. This reduces the task to draw a complicated shape to just loading a template image and setting some integer values for the colors. Anyway I wonder how to present this in Zope perhaps in a Zope product. I have to load the template from enywhere change the colors in it and display it in a reasonable format (perhaps using PIL to convert the resulting XMP to GIF to reduce bandwidth usage). I have no idea how to propagate the final image. Any ideas Andreas.

Hi, does anybody know how to set HTTP headers with TAL (if possible). I want to do HTTP caching with Apache as explained here: http://www.zope.org/Members/rbeer/caching . These the lines in DTML: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <dtml-call "RESPONSE.setHeader('Expires', _.DateTime(_.DateTime().timeTime() + 3600).toZone('GMT').rfc822())"> <dtml-call "RESPONSE.setHeader('Last-Modified', bobobase_modification_time().toZone('GMT').rfc822())"> <HTML> ... Thank you for your help. Mitja
