ZTopics and Zope2.2.0a1 don't mix
by Bill Anderson 21 May '00

21 May '00

Just thought I would let people know that ZTopics 1.0 and the Zope 2.2.0 alpha (and the CVS version of Zope it appears) do not play nice together. As long as you use standard zope item properties, or non-ZClass objects, it works fine. However, try to use any ZClass items and 'additional' properties, and it fails on an attribute error regardin 'Vocabulary'. Process: o Create catalog, call it 'Catalog' o Give a DTML Document a property of 'TopicName', value of 'Testing' o Add the property to the index and metadata tables in the catalog o Add the DTML Document to the catalog (via find) o Create A ZTopic give it a search for 'Testing' (with quotes!) in the TopicName field o Look at your ZTopic. it should appear fine. o Now create a ZClass, inherit from 'ZCatalog: CatalogAware' o Give it an index_html method to see something when you look at it (optional) o Give it a propertysheet, and a property 'TopicName' o Create an instance of your ZClass, make sure it has 'Testing' as the value for TopicName. o Now look at your ZTopic. All will not be well; it will gripe about the Vocabulary. o Now change the query to meta_type, and for whatever your ZClass' metatype is Now look at your ZTopic folder, all should be well. If anyone has a fix, I would appreciate it (and am sure Amos would accept a patch, I am looking into that part of it myself, but have gotten a bit turned around and may have to shelve it for the night :-( ).

Calling External Method...
by Eric L. Walstad 21 May '00

21 May '00

I am trying to invoke a C++ program from an external method. Platform is Linux. The C++ program returns HTML. Note that the Python function is working properly from the Python command line; That is, ExecCGI.xCGI("./websim") outputs all the expected html. I have placed the C++ program in the same folder as the ExecCGI module. The C++ program works from apache: here's an example of the program's output, which is what I'm trying to get into Zope: http://63.203.42.146/cgi-bin/websim ExecCGI module: import sys, os, string def xCGI( cmdLine ): """ Run an external command and return its standard output as a string. """ f = os.popen( cmdLine ) lines = f.readlines() status = f.close() if status: raise "CGI returned error: %d" % status[1] return string.join( lines ) External Method that calls the C++ program: Id ExecCGI Title Test Function name xCGI Python module file (without suffix) ExecCGI DTML Method that calls the External Method: <dtml-var standard_html_header> <h2><dtml-var title_or_id></h2> <dtml-let cmdLine="'./websim'"> <dtml-var "ExecCGI(cmdLine)"> </dtml-let> <dtml-var standard_html_footer> Traceback: Traceback (innermost last): File /usr/local/Zope/lib/python/ZPublisher/Publish.py, line 214, in publish_module File /usr/local/Zope/lib/python/ZPublisher/Publish.py, line 179, in publish File /usr/local/Zope/lib/python/Zope/__init__.py, line 202, in zpublisher_exception_hook (Object: ElementWithAttributes) File /usr/local/Zope/lib/python/ZPublisher/Publish.py, line 165, in publish File /usr/local/Zope/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: TestWS) File /usr/local/Zope/lib/python/ZPublisher/Publish.py, line 102, in call_object (Object: TestWS) File /usr/local/Zope/lib/python/OFS/DTMLMethod.py, line 150, in __call__ (Object: TestWS) File /usr/local/Zope/lib/python/DocumentTemplate/DT_String.py, line 502, in __call__ (Object: TestWS) File /usr/local/Zope/lib/python/DocumentTemplate/DT_Let.py, line 145, in render (Object: cmdLine="'./websim'") File /usr/local/Zope/lib/python/DocumentTemplate/DT_Util.py, line 335, in eval (Object: ExecCGI(cmdLine)) (Info: ExecCGI) File <string>, line 0, in ?

Refresh adds objects to Add list again
by Kevin Dangoor 20 May '00

20 May '00

Hi, I'm working with a very simple Product. Whenever I Refresh it, it shows up an additional time in the Add list. Is this expected behavior? I don't think I'm doing anything odd at all in the __init__.py or in the product itself. The __init__.py consists of basically just a single context.registerClass...

20 May '00

I want to use this: <dtml-call "manage_addImage(id=REQUEST['id'], file=REQUEST['file'])"> <dtml-call "RESPONSE.redirect( URL +'/success_html')"> but have the images placed into a folder in Apache. Can I send them directly? I have a local fs in the same folder as the above doc, should i send the images there, will the really end up in Apache?

Using ReportLab with Zope
by Richard Folwell 20 May '00

20 May '00

To sound out what, if anything, other people are doing in this area: I am interested in using ReportLab with Zope, to provide an improved printed version of web-published documents. What I want to do is fairly straightforward, to create a PDF file with: - a title/cover page with control information - a table of contents - the body of the document, with a technical document style header and footer (title, docref, revision, date, page x of numpages, etc) Indexing would be nice, but that involves much more complexity and is outside the scope of what I need right now. Currently I have documents published from Zope, sourced either as HTML (DTML documents) or XML, with the intention to also produce documents whose content will come mostly from a database (clearly straightforward in Zope). I think what I need to do is find some way of re-directing the output from Zope (what would normally go to the browser) to an external program, which uses ReportLab to generate the PDF file from the HTML stream, and returns the location of the file to Zope to pass to the browser as a re-direct (so the browser gives the user the option to view or download the PDF file). Is this correct? Is anyone already working in this direction? Any hints or tips? Richard

How to use WebDAV?
by Richard Folwell 20 May '00

20 May '00

I am trying to use WebDAV (so far under Win98). IE5/File/Open(check "Open as Web Folder") - "http://localhost:8080" So far so good. IE5 opens a folder with the Zope files and folders visible, and I can navigate through the folders. However it is not clear how to work with files. Right-clicking on a file gives potentially useful options to Open or Send To. Open simply renders the file as if served normally through Zope, Send To does nothing - I tried sending to a plain text editor (PFE), my favorite HTML editor (CoffeeCup) and NotePad. Nothing happens. What am I doing wrong? Thanks, Richard
