Re: [Zope] convert python to dtml

Why do you want to recode into DTML? I think that is piece of good code and much faster than DTML. You could try following replacing (original line of your code, follows with DTML code), but not tested: > rec = context.test_select_sql() <dtml-call "REQUEST.set(rec , test_select_sql())"> > print "Fields definitions" Fields definitions > recordset = rec.dictionaries() <dtml-let "recordset = rec.dictionaries()" > rownum = 1 <dtml-call "REQUEST.set(rownum,1)" > for record in recordset: <dtml-in recordset> > print "Row %d" % (rownum), "check", record Row <dtml-var rownum>, check <drml-var sequence-item><br> > rownum = rownum + 1 <dtml-call "REQUEST.set(rownum,rownum+1)" </dtml-in> and so on on the rest of code. > for key in record.keys(): > print key, "=", record[key] > print "-" * 80 > return printed

Need to programmatically change image content
by John Schinnerer 03 Sep '04

03 Sep '04

Hello, I need to programmatically replace the 'content' (e.g. the image file data, if I grok correctly) of an Image object with new data via file upload from web form. I imagine I could just delete the existing object and then add the new one... Is that the best/easiest way, or is there some slick way to replace the image file data for a given Image object? thanks, John S. __________________________________ Do you Yahoo!? Yahoo!

SystemError: NULL object passed to Py_BuildValue
by Olivier Laurent 09 Aug '04

09 Aug '04

I have this weird error comming up at random intervals: SystemError: NULL object passed to Py_BuildValue It occurs in a Plone site but I don't think it's related to Plone. I have no access to some error log or to the Control Panel since it's showing me the Plone login form whenever I want to access to restricted information. Thanks to the event.log, here is the traceback: - - - - - - - - 2004-06-03T17:33:19 ERROR(200) SiteError http://www.my_site.net/login_form Traceback (most recent call last): File "/usr/local/lib/zope2.7/lib/python/ZPublisher/Publish.py", line 104, in publish if transactions_manager: transactions_manager.commit() File "/usr/local/lib/zope2.7/lib/python/Zope/App/startup.py", line 221, in commit get_transaction().commit() File "/usr/local/lib/zope2.7/lib/python/ZODB/Transaction.py", line 233, in commit ncommitted += self._commit_objects(objects) File "/usr/local/lib/zope2.7/lib/python/ZODB/Transaction.py", line 348, in _commit_objects jar.commit(o, self) File "/usr/local/lib/zope2.7/lib/python/ZODB/Connection.py", line 413, in commit state=object.__getstate__() SystemError: NULL object passed to Py_BuildValue - - - - - - - - Python version: 2.3.3 (#1, May 18 2004, 08:35:20) [GCC 3.2.2 20030222 (Red Hat Linux 3.2.2-5)] Zope version: 2.7 Plone version: 2.0-rc6 Any clue on what's going on.

How to get exact requested URL (was: Current location: is my script reliable?)
by Tonico Strasser 13 Jul '04

13 Jul '04

If you need the exact URL that was requested by the browser including *) trailing and double slashes and *) query strings, then the attached script is for you. Example usage: tal:define="location here/location" tal:attributes="href string:$location#documentContent" I've tested it with several Zope versions and vhost setups. Related issues: Skipnav loads new page <http://plone.org/collector/2775> base tag differs from actual url <http://plone.org/collector/2988> VIRTUAL_URL <http://collector.zope.org/Zope/1252> Need "actual URL" method <http://collector.zope.org/Zope/1308> HTH Tonico ## Script (Python) "location" ##bind container=container ##bind context=context ##bind namespace= ##bind script=script ##bind subpath=traverse_subpath ##parameters= ##title= ## request = context.REQUEST server_url = request['SERVER_URL'] path_info = request['PATH_INFO'] query_string = request['QUERY_STRING'] path_info = path_info.split('VirtualHostRoot')[-1] # This is needed with Zope.cgi (don't know why). if path_info.startswith('//'): path_info = path_info[1:] if query_string: query_string = '?%s' % query_string location = server_url + path_info + query_string return location

confused on permissions and roles
by John Hunter 09 Jul '04

09 Jul '04

I have a class that inherits from RoleManager (via Folder). It defined additional roles, including 'Administrator'. I would like the Administrator to be able to view management screens and create objects of certain types, but not be able to delete or rename objects of certain types. I tried using a ClassSecurityInfo instance as follows (I've removed the copy/delete objects part for simplicity and am just focusing on the view management screens part) class Myfolder(Folder): """ The base folder for the product """ meta_type="Myfolder" __ac_roles__=('Manager', 'Administrator', 'Researcher', 'Reviewer') security = ClassSecurityInfo() security.declareObjectProtected() security.declareProtected('View management screens', 'manage') # ..snip my methods ... security.setPermissionDefault('View management screens',('Manager', 'Administrator')) But a user with just an Administrator role could not view the myfolder/manage screen I also tried using __ac__permissions__ class Myfolder(Folder): """ The base folder for the product """ meta_type="Myfolder" __ac_roles__=('Manager', 'Administrator', 'Researcher', 'Reviewer') __ac_permissions__= ( ('View management screens', ('manage','manage_main'), ('Manager', 'Administrator'), ), ) with the same result. In both cases if I visit the Security tab of that folder (as a Manager) none of the default check boxes for the various roles and permissions have been altered; ie, the one for "View Management Screens" still has "Acquire Permissions Settings" checked. My specific question is, what am I doing wrong? My more general question is what is the interplay between using ClassSecurityInfo and __ac__permissions__? Should both be set, or should the latter be used to handle everything? Thanks, John Hunter zope 2.7

Catalog - exclusive-or?
by Paul Winkler 06 Jul '04

06 Jul '04

Hi, I have a bunch of objects (CMF content but I don't think that's relevant to the question) which are conceptually closely related - they are different versions of the same content. I want to be able to ensure that a search returns at most one of the related objects. I can't think of any way to do this with stock ZCatalog, and I've been looking at Dieter's AdvancedQuery but can't quite sort it out there either. The semantics I want are like this: given a FieldIndex F, an object o, and a query parameter foo, o is a match if o's value for F is foo or o's value for F is "default" AND there are no relatives of o whose value for F is foo I think I could implement this with a bunch of post-processing of the query results, but that seems likely to be slowwww. any ideas? -- Paul Winkler http://www.slinkp.com

LocalFS 1.3 for Zope2.7.1 released
by Andreas Heckel 06 Jul '04

06 Jul '04

EasyLeading.org is happy to announce the release of LocalFS 1.3-andreas. LocalFS lets you deliver static files from your local file system. The new version uses a filestream_iterator implementation introduced with Zope2.7.1. The major enhancement is to allow LocalFS to serve static files from the filesystem without first needing to read all file data into memory or explicitly chunking data from static files out via RESPONSE.write (both of which are slower than just letting medusa itself handle the output via a native producer). If LocalFS can't import filestream_iterator it uses the old method to serve files. Therefore it is backward compatible to Zote2.6 and Zope2.7.0 This is free software and you can download it at: http://www.easyleading.org/Downloads/ Greetings Andreas Heckel
