ZClasses and ZSQL
by David Kyte 08 Jan '02

08 Jan '02

Hi, Has anyone any experience of using ZSQL in ZCLASSES. I installed a connector in the ZCLASS within my product. The ZSQL method couldn't find the connector. I then placed the connector in the Product directory and the ZSQL method found it ok. I could then test the ZSQL method - works fine. I then tried to install my product and couldn't get the class to find the connector. I guess my problem is one object referring to another object in the ZCLASS. Can anyone enlighten me? Thanks Dave

pdf + external methods question
by Garry Steedman 08 Jan '02

08 Jan '02

Hello all, after _much_ wailing and gnashing of teeth, i am now happily churning out PDF reports via reportlab/ external methods, but i still have one irritation: i am using a tempfile.mktemp(suffix=".pdf") object to chuck the pdf into but am having trouble responsing this back to the browser cleanly. i am using this code (thx, messrs Washington + Penny!): c.save() self.REQUEST.RESPONSE.setHeader('Content-type', 'application/x-pdf') self.REQUEST.RESPONSE.write(open(mypdffile).read()) but the tempfile object seems to get mangled somewhere in the process and the client doesn't recognise the file as PDF because the PDF suffix gets lost somewhere... any help most welcome... if anyone wants to enlighten me regarding what ext methods can or should return, i would also be grateful! i would like to write a HOWTO on reportlab + zope once i've got this stuff finished... cheers, garry __________________________________________________ Do You Yahoo!?

Re: [Zope] Currency formatting from within Python Script
by complaw＠hal-pc.org 08 Jan '02

Is there an easier way to simply have a float display (round) to two decimal places, rather than monkeying around with the access restrictions? I can add the '$' to the string.

Zope Book review and Zope Linkfest available at www.skippingdot.net
by Shane McChesney 08 Jan '02

08 Jan '02

Hi all, Longtime listener, first time caller... I launched a site last month called Skipping Dot Net, subtitled "Building Next-Generation Web Services and Apps Without Paying The Microsoft Tax". As you might guess from that, it's all about advocating alternatives to MS technologies, especially open source approaches, and especially what I see as the really good ones like Python and Zope. I'm not a Python or Zope guru, not by a long shot, but I'm learning as fast as I can, because we're working to migrate all of our existing ASP/VB apps to Zope ASAP. As part of my learning process, I'm reading and reviewing every Zope book published, and I started that effort with a review of the (first) Zope Book by Amos Latteier & Michel Pelletier. That review can be found here: http://www.skippingdot.net/2001/12/20 If you think it might be of any use to you, feel free to give it a read. I'll be reviewing the Zope Web Application Construction Kit from Sams later in January and The Book of Zope from No Starch Press in February. In addition to those, there are three more Zope books coming out in the near future, for a total of six, and I'll review each of them as soon as I can get my hands on them and read them cover to cover. The list of upcoming books and my pile of other Zope links is at: http://www.skippingdot.net/2001/12/19 There's also a review of Programming Web Services With XML-RPC (O'Reilly) at: http://www.skippingdot.net/2001/12/14 I'm updating the linkfest regularly as I come across new resources, so if there's anything you think I should add, just let me know. I'm sure I'm missing plenty. In addition to Python and Zope, I'm covering XML-RPC, SOAP, RSS, Jabber, and weblogging technologies to the best of my abilities -- or more accurately, to improve my abilities. The intersections of all these things, like Zope & Jabber together, XML-RPC and Zope, SOAP on a Zope, are what I'm most excited about for my projects and my clients. Any feedback, links or advice that could help me get up to speed in these areas would be much appreciated. Thanks for your time and your mental bandwidth, Shane McChesney President, Wesearch Information Services Inc. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Contact Details: -- Email: shane(a)wesearchis.com Web Sites: -- http://www.wesearchis.com (Company home page) -- http://www.skippingdot.net (Regularly updated weblog) -- http://www.nooro.com (Professional web surveys) -- http://www.fetchserver.com (Enterprise RSS newsreader) -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-

DTML-stuff calling from Python Script
by bogdan＠iuveno-net.de 08 Jan '02

08 Jan '02

Hello. How to call an DTML Method from Python Script? It could be same as from DTML stuff: <dtml-var somewhere.script(value)> or <dtml-call expr="..."> But vice versa (dtml-method from script) always fails in anyway: ------------------------ print context.doc_here return printed ------------------------ Works, but just prints the source (not parses) ------------------------ return context.doc_here(_,_) ------------------------ Fails with "guarded_getattr" ------------------------ return context.doc_here(_) ------------------------ Fails with "standard_html_header" (key_error) ------------------------ return context.doc_here ------------------------ Works, but just prints the source (quoted, not parses) Anybody know how to call it? Documentation claims, that it should work. But it does not. P.S. Namespace defined as well. -- Sincerely yours, Bogdan M.Maryniuck
