MIMETag.py patch
by Ava 29 Nov '99

29 Nov '99

Hello, I found myself having a need to send mail with the ability to customize stuff like disposition, name, filename, encoding, etc. I modified the MIMETag to allow the use of type_expr, disposition_expr, encode_expr, name_expr, filename_expr, and skip_expr attributes in the mime and boundary tags. * type_expr, disposition_expr, encode_expr, and name_expr work like type, disposition, encode and name, except that they take expressions instead of names. * filename_expr allows to give the filename of the attachment. Note that the filename attribute is included only if the disposition attribute is set, and that in the header, the filename attribute is attached to the Content-Disposition: header, just like the name attribute is attached to the Content-Type: header. I don't know if it is ok, but it seems to be the way Netscape Messenger and Microsoft Outlook do it. * skip_expr allows to skip an attachment if the skip_expr evaluates to true. Here is an example. document is a FileUpload object. <dtml-sendmail mailhost=MailHost> to: you(a)anywhere.com from: me(a)nowhere.com subject: this is the subject <dtml-mime type=text/plain> Thanks for you input. <dtml-if "document.filename"> The file you attached is <dtml-var "document.filename"> <dtml-else> You did not attach any file </dtml-if> <dtml-boundary disposition=attachment filename_expr="document.filename" name_expr="document.filename" skip_expr="not document.filename" type_expr="document.headers['Content-Type']" encode=base64><dtml-var "document.read()"></dtml-mime> </dtml-sendmail> Please send me any comment on this work.

Calling from an Overriding function
by Itamar Shtull-Trauring 28 Nov '99

28 Nov '99

I'm trying to override manage_beforeDelete(self,item,container) in a python class that inherits CatalogAware. The overriding manage_beforeDelete calls the base class function: from Products.ZCatalog.CatalogAwareness import CatalogAware class Workflow(CatalogAware): def manage_beforeDelete(self,item,container): """ """ ... CatalogAware.manage_beforeDelete(self, item, container) I get this error message: Error Type: TypeError Error Value: unbound method must be called with class instance 1st argument -- Itamar S.T. itamars(a)ibm.net

Using asyncore in external methods
by Petru Paler 28 Nov '99

28 Nov '99

Hi, I have an external method which calls a function from a module. That module opens a couple of sockets and polls on them. The problem is that 'socket_map' from asyncore.py is global, so things conflict with ZServer's use of asyncore. Which is 'the right way' to use asyncore with Zope ? -Petru

A product, Zope 2.1.0b2 - when I try to add an instance, I get :- Error type: cPickle.PicklingError Error value:: Cannot pickle objects.

Lobby: Renderable ZClasses
by Lalo Martins 27 Nov '99

27 Nov '99

Kevin Howe wrote a version of my ``Renderable base ZClass'' which plugs directly into the ZClass system. Background info: a Renderable ZClass is one with control of what happens when you <dtml-var some_object_of_this_class>. Kevin's version is really cool, but it patches stuff outside Products/Renderable, so I won't distribute it as the ``official'' Renderable Product. Still, I'd like to lobby for its inclusion in Zope itself. How it works: when you create your ZClass, you select ``Renderable'' as one of the base classes. Then (in Kevin's version) in the Basic tab you select some method to be executed when people <dtml-var some_object_of_this_class>. My BannerAd Product and Kevin's ActiveImage Product both use Renderable. AFAIK, both work with my version and Kevin's. []s, |alo +---- -- I am Lalo of deB-org. You will be freed.

Is the first not chinese? As i understand it, chinese is a multibyte character set, we have not done any work to explicitly support them. I'm not even sure if these issues have been worked out in Python yet. -Michel

HP E-speak and XML-RPC
by Ross J. Reedstrom 26 Nov '99

26 Nov '99

Hey Zopistas: Just ran across this from cnet (via slashdot): "HP releases code to e-commerce software" It's about HP's 'Espeak' web commerce/interaction/standard gizmo-what-have-you. From 30,000 feet, the intent looks like something that could be fulfilled with some defined XML-RPC. Anyone here know enough about the two to know how they would interact/compare? Does Espeak define a wire protocol? Would this be something to fold into Medusa? Uninformed minds want to know! Ross -- Ross J.
