Problem with links containing non-ascii characters in StructuredText
by Maurits van Rees 30 Sep '05

30 Sep '05

Hi, I have a problem getting links to function in StructuredText when they have non-ascii characters in the title. - This will render as a link: "Zope website":http://zope.org/ - This will render literally: "Zöpe website":http://zope.org/ [Notice the diaeresis in the second case.] This can of course be solved by using html entities like 'ö'. But I have just started using utf-8 so I don't have to bother myself with writing html entities. There is probably a Python method that can translate 'ö' into 'ö', but I would like the resulting html code to be humanly readable utf-8 as well. I wouldn't mind iso-8859-1 as that's what it basically is in my case (I'm Dutch) but utf-8 seems the way to go. Anyway, here is a script that illustrates the problem. It has some extra non-ascii characters thrown in just to show that these characters don't give any problems outside of the links. ------------------ import Products.PythonScripts.standard print """ <html><head> <meta http-equiv="Content-Type" content="text/html;charset=utf-8" /> </head><body> """ text=""" Let's link to a "Zope website":http://zope.org/. Nó. Let's lïnk to à "Zöpe website":http://zope.org/. """ ppss=Products.PythonScripts.standard.structured_text print ppss(unicode(text, 'iso-8859-1').encode('utf-8')) # The following line has the same effect: #print unicode(ppss(text), 'iso-8859-1').encode('utf-8') print "</body>" return printed ------------------ Don't worry, this is not how I usually make my pages. ;-) This results in the following html source code: ------------------ <html><head> <meta http-equiv="Content-Type" content="text/html;charset=utf-8" /> </head><body> Let's link to a <a href="http://zope.org/">Zope website</a>. Nó. Let's lïnk to à "Zöpe website":http://zope.org/. </body> ------------------ That last failed link is obviously not as it should be. Does anyone know a solution? I failed to find one with Google. I wondered if it had to do with the diaeresis specifically, but the same thing goes wrong with e.g. 'Zópe'. BTW, I use the Debian Sarge version of Zope 2.7.

Using the set object within page templates
by Floyd May 29 Sep '05

29 Sep '05

How can I use a set object within a page template? When I attempt to create a set (e.g. tal:define="myset python:set(some_list)"), zope complains that the name 'set' is not defined. Thanks! fm

Using Singletons
by Doyon, Jean-Francois 29 Sep '05

29 Sep '05

Hello, Is there any support within the framework for singletons? What I call singletons are objects that are instanciated and persisted only once, or at least should be. I find myself wanting to use these in several instances, notably when I create a class/object that acts as a gateway to an external system of some kind (like a web service). I create an object that provides a pythonic/zope-ish API to the rest of my objects/product code. I often like to use a persistent object (vs. a regular python module/package) in order to take advantage of things like caching, or giving options for configuration through the ZMI. Given this use case, it would be nice to have Zope provide a framework to support such things. It could enforce the uniqueness of the object in the entire system (absolutely no way to add more than one), and maybe provide a global mechanism to "find" the object not needing to know where in the tree it is, what it is called, or using the catalog (rather expensive?). Maybe something like a singleton flag and registry of somekind? I can kind of achieve this partly by doing things like "visible=0" is my CMF registration for example, forcing a specific id, enforcing rules in the manage_add type methods, and so on, but it all seems so kludgy. Not to mention I always have to know the name of the object, and possibly even the path, to get to it ... Redundant when there's always only one! I'm not looking for solutions, but ideas and thoughts ... Although if someone knows of ways to do this nicely, maybe with a third-party product for example, I'd love to hear about it!

Zope Debugger 0.8.0 Released!
by Chris Withers 29 Sep '05

29 Sep '05

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

That solution was given to me by someone on the zope mailing list by the time Zope 2.8.0 was out :) -----Original Message----- From: Chris Withers [mailto:chris@simplistix.co.uk] Sent: 29 September 2005 09:26 To: Pascal Peregrina Cc: Luca Olivetti; plone-users(a)lists.sourceforge.net; zope(a)zope.org Subject: Re: [Zope] Zope Debugger 0.8.0 Released!

If what is intended with this code is to monkey patch some class, then I had a similar problem on 2.8.0 and I solved it by using setattr() instead of item assignment (and it works with 2.7.6).

SiteAccess (Enh. VHM) still needed, or merged to Zope?
by Jeff Kowalczyk 29 Sep '05

29 Sep '05

Most references I find (google, The Plone Book - McKay, Building Websites W/ Plone - Cooper) on virtual hosting Zope behind Apache recommend starting with sfm's SiteAccess enhanced Virtual Host Monster product: http://www.zope.org/Members/sfm/SiteAccessEnhanced/view Reportedly last updated 2001-08-19, is SAE really so mature that it has not subsequently needed updates or merited a merge into Zope's own VHM? I need to map the incoming URL "http://(*.)foo.com/new/*" to a Plone instance at "http://localhost:8080/foo/*" , and later change the inbound mapping to "http://(*.)foo.com/*" after customer acceptance. I'm guessing that this is the most vanilla virtual hosting requirement possible, and I want to use the simplest configuration to accomplish it. If the old SEH 2.1.0 is the recommended tool with Zope-2.8.1, I'm sure the existing docs will be enough to figure it out. Thanks.

Re: Output only the first or a particular record using TAL
by Julian Yap 29 Sep '05

29 Sep '05

Thanks Tres, Sascha and Jirka for your help. I used the following and it works great (without some formatting for clarity): <tr tal:define="customer container/getCustomerLicences" tal:condition="customer"> <td>Customer: </td> </tr> The above condition checks that 'customer' is not empty. I think I'll need to do some more reading up on "path expressions" and "python expressions". Still mentally confusing to me. Julian

Re: [Zope] Help with virtual hosting Zope on different ports

I was a little reluctant to try this, since I'm not that agile with installing unix applications, but I gave it a shot. It actually wasn't that hard to install, and the performance difference it makes on my rickety old box is astonishing! Thank you very much for this tip!
