ZPatterns bug: typo in Transactions.py
by Steve Alexander 14 Sep '00

14 Sep '00

ZPatterns, latest released version. def abort_sub(self, transaction): In Transactions.py, aborting a subtransaction will fail because of a method signature mismatch. Was: def abort_sub(self, transaction): self.tpc_abort() Should be: def abort_sub(self, transaction): self.tpc_abort(transaction) I think there's something not quite right about the way ZPatterns is handling subtransactions, even with this patch, and the other one related to Transactions.py that I posted a while back. Is there any detailed documentation about how Zope transactions and subtransactions are supposed to work? -- Steve Alexander Software Engineer Cat-Box limited http://www.cat-box.net

Well, the first line above doesn't have quotes, so I assume you used "print". The second line does, so I assume you just evaluated it, in which case it takes the repr of the string and therefore quotes the backslashes by doubling them. > Can you explain why that makes sense please ;-) > Surely it'd be more useful to default to SOFTWARE_HOME including > '/lib/python' so that old code wasn't broken? Well, old code presumably wouldn't use INSTANCE_HOME, so it wouldn't arise. I don't know why that default was chosen. > And that'll work in INSTANCE_HOME (in either the base or instance parts) > Zope installs as well as non-instance home ones? It will work regardless of where the Product lives. "product_home" is a non-Zope-specific function which extracts the path of a module in a package from that module's global dictionary.

is INSTANCE_HOME broken on Win32?
by Chris Withers 14 Sep '00

14 Sep '00

Hello :-) I'm trying to make Squishdot work with INSTANCE_HOME nicely. However, the testing is going wrong on a normal Win32 Install... I had lots of lines that went something like: f=open('%s/Products/%s.dtml' % (SOFTWARE_HOME,file)) Which generates: E:\Zope\2.2.0\lib\python/Products/Squishdot/validArticle.dtml That's not very nice in itself but seems to work with Python's open... However, when I change them all to be like, for example: f=open('%s/Products/%s.dtml' % (INSTANCE_HOME,file)) I then get: 'E:\\Zope\\2.2.0/Products/Squishdot/validArticle.dtml' which is: - horrible - wrong - doesn't work ;-) Anyway, I'm looking for something like INSTANCE_HOME or SOFTWARE_HOME that: - works in an INSTANCE_HOME setup - works in a non-INSTANCE_HOME setup - works on both Unix and Windows.. Any ideas? cheers, Chris

Making some DTML Documents catalog aware
by Christian Couder 14 Sep '00

14 Sep '00

Hi everybody, I already posted this message to the zope(a)zope.org list but I had no answer. I have a Zope site with many DTML document and I would like to make them catalog aware because I want the web site users to be able to search the site. The web site users are already able to modify the site themselves and this functionality must be kept. I use the debian zope package version 2.1.6-5.2. My first thought was to create a new ZClass that inherit from both the CatalogAware and the DTML Document class but it seems to be quite difficult. First the How-To: DTML Zclass ID Bug Workaround helped a little, but when I try to map some DTML methods to some views in the "Views" tab of my class, no tab for the view are displayed for the class instance. I also searched the news and the documentation and it seems that many people faced some problems when inheriting from both CatalogAware and DTML Document. So now I suppose this is not the best way to solve my problem. Do some people have succeeded in something like this ? Thanks in advance for your answer. -- Christian COUDER christian(a)alcove.fr Ingénieur Informatique Libre Alcôve - http://www.alcove.fr/

ZPatterns guestbook example
by James Johnson 13 Sep '00

13 Sep '00

Hello, I ran across a previous post regarding a simple ZPatterns based example you were working on. Did you ever get it working? How about any other basic working example. I understand the concept I'm not sure on the implementation. What would help me the most is a simple step by step guide like this. Create product folder. Place a ZClass derived from dataskin. Go to the default rack and select the ZClass as storage. I understand I have choices where to put the methods depending on what I'm trying to achieve. I just want to "make" ZPatterns store a single property in the dataskin zclass. I've tried putting methods everywhere. I thought you placed them in the specialist and then called specialist.propertysheets.Mysheet.manage_whatever(). Now I'm thinking the specialist goes into the dataskin. I think I should be able to get a simple working example using a specialist,ZClass, and a factory to add the product to the add list.

Will the SkinScript How-to help me put together something that works?
by James Johnson 13 Sep '00

13 Sep '00

I can't seem to make ZPatterns do anything. Can somebody help me out. I don't need code help just a basic how-to structure a working example using real objects, like dtml methods, sql methods or whatever. I really want to use and support the Zope and ZPatterns system. Until then I'm going to keep trying.

Convert from HTML to DOC or from PDF to DOC.
by Juan Javier Carrera Obrero 13 Sep '00

13 Sep '00

Hi, We are trying to generate a document from Zope with a format no HTML. We have used the library "reportlab" (http://www.reportlab.com) to generate it in PDF format (with python). It is very useful, however we want now to generate it in DOC format (for Microsoft Word). I know that Microsoft Word opens a HTML document directly, but when I open a HTML document with Microsoft Word (v. 97), the document aspect is erased. Anybody to know any Zope product what allows to convert from HTML to Microsoft Word, or from PDF to Microsoft Word, or well, any similar way ? Thanks.
