How to create a file and send it by e-mail ?
by Nicolas Georgakopoulos 11 Oct '05

11 Oct '05

Hello all, I'm developing using ZPT and I need to create a file (CSV format) but I'm having some problems: * 1. *I only know how to create files with python but I get an * Error Type: NameError* * Error Value: global name 'file' is not defined. * I think ZOPE doe's not allow python to create files for security reasons. Can I change this security policy or it will make my application unsafe? Is there another way to create a file using ZOPE API calls ? * 2.*When I create my file how can I send it as an attachment by mail ? (I already have setup my mail host object and I can send mail's successfully.) thanks for your time.. * *

Why do you think you need to? Is the csv data dynamically generated? If you need to store it, create a Zope File Object in the python script that processes submission from your ZPT. >>> * 2.*When I create my file how can I send it as an attachment by mail >>> ?

You'll want to build your own MIMEBase object and attach it to the result of rendering your Mail Template if you build your csv in a string. If you end up with a Zope File object or a ZPublisher FileUpload object, then you can just do: msg = context.my_mail_template.as_message( # insert your params here ) msg.add_file(your_file) There's plenty of examples in the readme.txt file, or in the tests folder... cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk

Zope Debugger 0.8.1 Released!
by Chris Withers 11 Oct '05

11 Oct '05

This release adds support for both Zope 2.7 and Zope 2.8. Zope Debugger is an enhanced version of pdb for use with Zope. It can be used simply by inserting the following lines in any python code you'd like to debug, including Script (Python)'s and FSPythonScripts: from Products.zdb import set_trace set_trace() It requires no changes to Zope, CMF or Plone or any funky interaction with any specific kind of editing software. All you really need to do is insert the snippet above and make sure your Zope instance is running in foreground mode. For more information, please see: http://www.simplistix.co.uk/software/zope/zdb cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk

Re: [Zope] Zope Debugger lets WingDbg fail to connect toclient
by Chris Withers 11 Oct '05

Hi Peter, Frey, Peter wrote: > > sorry, here it is. It is the the WingDbg Product, but you probably will be unable to install/use it as it depends on the WingIDE (at least part of it) to be installed on the server, too. And as WingIDE is not open source, I am not allowed to hand it on. Yeah, I don't need it to run, just wanted to take a look. The patching is a bit worse than I expected, it doesn't look like WinDbg makes any attempt to call back to the original version of the method it's patching, which is a bit sad :-( That said, I'd expect zdb not to work when WinDbg is installed, and not the other way round... I'm CC'ing in a support address I found for Wing-IDE in the hope that one of those guys will contact me. I believe zdb replaces a lot of the code they currently have in WingDbg, hopefully I can persuade them to use zdb instead, then everyone can be happy ;-) cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk

RE: [Zope] reading zope.config file for ClientStorage
by Mika, David P (Research) 11 Oct '05

11 Oct '05

I've taken a look at stepper and dug into the zope source again. It looks like both are relying on a startup script akin to zopectl to marshal everything correctly. I would rather not be using a startup script (besides I couldn't sort it out); this is what I have so far: from Zope.Startup import options, handlers opts = options.ZopeOptions() opts.configfile='c:\Zope-Instance-Test\etc\zope-with-zeo.conf' opts.load_schema() opts.load_configfile() unfortunately in the resulting options object, I'm not getting the stuff I need from the conf file, namely the ZODB storage stuff needed for ClientStorage. The schema file that is being used by ZopeOptions is Zope/Startup/zopeschema.xml. This only has a skeleton zodb_db section. It looks like the meat & potatoes are in ZODB/component.xml, but I don't see how that is actually pulled in. Any more ideas?

Any ideas? Have a look at the run.py file in Stepper: http://www.simplistix.co.uk/software/zope/stepper It shows you how to parse zope.conf without having to start Zope up... You may wish to wait for Stepper 1.3.0, though, which shows you how to do this for both Zope 2.7 and Zope 2.8... cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk

LocalFS problems with @import-ing stylesheets
by Paul Smith 11 Oct '05

11 Oct '05

Hi We've just upgraded to using LocalFS (LocalFS-1-3-andreas for the large file support) with Zope 2.7.2, and have been experiencing problems with accessing stylesheets via the @import command from within a LocalFS folder. eg: <style type="text/css" media="screen">  </style> where /site is the LocalFS folder. The problem only manifests itself using Mozilla browsers (Mozilla, Firefox, etc), and when using these browsers stylesheets are successfully requested (according to the Apache access logs) but are ignored within the page. The stylesheet validates, and works as expected if moved inline within the page, or when created as a Zope File object, rather than within LocalFS. This all worked fine on the previous versions of LocalFS we were using (1.1.0) with Zope 2.6.4. Any ideas if this is a Zope or a LocalFS thing?

Yes the client is not loggin in. (and since it will be a commandline script it is not supposed to do). If I hardcode some bogus data to be returned it works fine. But as soon as something in the catalog is searched it does not work. So the xmlrpc works. If I run the script from the browser (with default parameters) logged in as Manager it works. So the functionality works. But really searching for something through xmlrpc does not work. If I copy & paste the code in an (ZODB) Python script which I give the Authenticated proxy role it works perfect. So I suspect the conclusion is that the external method lacks that proxy role.... -- __________________________________________________ "Nothing is as subjective as reality" Reinoud van Leeuwen reinoud.v(a)n.leeuwen.net http://www.xs4all.nl/~reinoud __________________________________________________
