Dynamic script loading
by Pawel Lewicki 17 Nov '03

17 Nov '03

Hello, I don't know if my question is more zopish or pythonish. I have a Zope product. I had to add the specific functionality which is needed very rarely. I would be glad to import external module only when it is needed, do the job and free my mind and extra memory it consumed. How should I do that? I have to admit that I don't find myself as an experienced Python programmer. I just discover depths of this incredible language while extending my Zope product. Maybe anyone would help me with some relevant links. Thanx in advance, Pawel Lewicki

Temporary Folder Content - Session Data
by Edward Pollard 27 Sep '03

27 Sep '03

Sometimes I feel really bad writing to the list for help. It's when I have very simple, very basic questions. I'm sure that the answer is somewhere, but I've not been able to find it. I'm having a thought that each of my Zope projects that uses sessions should use individual session containers. I had some problems when one of our student developers and I both shared the same variable names. Quite hilarious. However, it seems to be conventional wisdom to store session data containers in temporary folders, as the default session data container is. This of course goes away on a restart. Is there anyway to get them to stick, as the default session data container does? Thanks a ton Edward

External Editor stopped working for me
by Roger Fisher 12 Sep '03

12 Sep '03

I love the External Editor product - it's worked flawlessly on a Win98 system. I just moved to a Win/XP system. External Editor worked for about a week, but now for some reason always fails with: FATAL ERROR: {Errno 1] No such file or directory: C:\\Documents and Settings\\Roger\\Local Settings\\Temporary Internet Files\\Content.IE5\\mumble\object[1].zope I'm wondering why this worked for awhile, and now stopped. And for some reason, my actual directory structure now includes ...\Local Settings\Temp\Temporary Internet Files\Content.IE5 Not sure how the extra Temp got in there, or how to circumvent it. Thanks for any advice.

Integrating Zope with the file system
by Stan Baptista 18 Jul '03

18 Jul '03

Hi all, I want to integrate my Zope/Plone portal with files on the Lan. Does a product exist that: 1) Allows viewing/editing of (e.g.) Windows files w/out requiring that they be made Zope objects? 2) Does not have security holes since the files would be available via the Internet. 3) Provides text search capability, again, w/out requiring that they become Zope objects?

I have the following problems: I have installed Zope 2.6 which is on Linux Suse 8.2 with the installation tool of Linux. With python zpasswd.py inituser I have set users (this was done when I was logged in as root). When I give in the browser: http://localhost:8080/manage I get the login page for Zope, but when I login the it outputs the failure that I have no authorisation (when I was logged as user who I have created before). Can you help me, please? wbr Ali

WebDAV Metadata
by Holger Schmidt 04 Jul '03

04 Jul '03

Hi, --- Using WebDAV you are able to attach Metadata to a document by calling PROPPATCH and you can get this Metadata by calling PROPFIND ... Zope saves these Properties in the ZODB. Properties are handled by OFS.PropertyManager.PropertyManager and for the Presentation OFS.PropertySheets.PropertySheet is used ... --- I think it should be possible to "redirect" this Metadata, so a PROPPATCH would save the Metadata to 'MY' MySQL-DB and a PROPFIND would get it from 'MY' MySQL-DB ... Has anybody ever done something like this before? Any ideas how to manage this (in a product ...)? -- Thanks, Holger

create Catalog via PythonScript?
by Bill Seitz 04 Jul '03

04 Jul '03

I'm going to want to create catalogs in a number of folders. So I'd like a script - not only is it easier to edit than an External Method, but it uses acquisition so I can just put it at a top level and then use the calling URL to determine the location. But permissions are the problem: "You are not allowed to access ZCatalog in this context" Can this problem be overcome by something like what's in here: <http://www.zopelabs.com/cookbook/991933953> ?? thx __________________________________ Do you Yahoo!?

zope tal / external method woes continued...
by Jeffrey Hood 04 Jul '03

04 Jul '03

I (finally) got my permissions problem with my external method solved, by changing the ext method to return a list of lists: def getAll: rows = ... # get data from soap call results [] for row in rows results.append( row[0], row[1], row[2] ) return results this gets the data and returns it in a list of lists: [['1', 'Fido', '5.00'], ['2', 'Spot', '10.00'], ['4', 'Sparky', '24'], ['9', 'Buffy', '10'], ['10', 'Bobby', '50']] my tal code looks like the following: <p tal:content="here/getRecords"> </p> <table border="1" tal:define="data python:here.getRecords()"> <tr tal:repeat="record data"> <td tal:content="python:record[0]">record item 1</td> <td tal:content="python:record[1]">record item 2</td> <td tal:content="python:record[2]">record item 3</td> </tr> </table> Neither of the above work... on both counts, now I get: ------------------------------------------------------------------- Exception traceback Time 2003/06/30 15:32:49.218 US/Eastern User Name (User Id) Anonymous User (None) Request URL http://jhoodxp.hmcon.com:8081/jhood/show_records Exception Type TypeError Exception Value sequence index must be integer Traceback (innermost last): * Module ZPublisher.Publish, line 98, in publish * Module ZPublisher.mapply, line 88, in mapply * Module ZPublisher.Publish, line 39, in call_object * Module Shared.DC.Scripts.Bindings, line 252, in __call__ * Module Shared.DC.Scripts.Bindings, line 283, in _bindAndExec * Module Products.PageTemplates.ZopePageTemplate, line 228, in _exec * Module Products.PageTemplates.PageTemplate, line 95, in pt_render <ZopePageTemplate at /jhood/show_records> * Module TAL.TALInterpreter, line 200, in __call__ * Module TAL.TALInterpreter, line 244, in interpret * Module TAL.TALInterpreter, line 497, in do_insertText_tal * Module Products.PageTemplates.TALES, line 223, in evaluateText * Module Products.PageTemplates.TALES, line 217, in evaluate URL: /jhood/show_records Line 34, Column 8 Expression: standard:'records/item' Names: {'container': <Folder instance at 01EAAC68>, 'default': <Products.PageTemplates.TALES.Default instance at 008AFF6C>, 'here': <Folder instance at 01EAAC68>, 'loop': <SafeMapping instance at 01F62578>, 'modules': <Products.PageTemplates.ZRPythonExpr._SecureModuleImporter instance at 008B0024>, 'nothing': None, 'options': {'args': ()}, 'repeat': <SafeMapping instance at 01F62578>, 'request': <HTTPRequest, URL=http://jhoodxp.hmcon.com:8081/jhood/show_records>, 'root': <Application instance at 019B27C8>, 'template': <ZopePageTemplate at /jhood/show_records>, 'traverse_subpath': [], 'user': Anonymous User} * Module Products.PageTemplates.Expressions, line 206, in __call__ * Module Products.PageTemplates.Expressions, line 194, in _eval * Module Products.PageTemplates.Expressions, line 150, in _eval __traceback_info__: records * Module Products.PageTemplates.Expressions, line 353, in restrictedTraverse __traceback_info__: {'path': ['item'], 'TraversalRequestNameStack': []} TypeError: sequence index must be integer ------------------------------------------------------------------- It seems (to me with my limited python/zope knowledge) that the tal is looking for something other than a list of lists, and it can't handle it... although now at least I don't have security issues... Question is... what can I do ??? If I have to change the return value, what should it be, and if I can use it, how can I use it with tal... This is driving me mad, since I *really* would like to use Zope for a project, but this is almost getting too frustrating... Thanks in advance... JH jhood .a. hmcon .d. com
