Beginners Confusion
by Russell Winter 04 Dec '05

04 Dec '05

Folks, I am trying to understand instances, any help or suggestions would be appreciated as I am obviously missing something. I would like to have each user having, either, their own Zope Server binaries (including CMF & Plone) in their home directories. Alternatively, as multiple Zope Servers on one machine will be quite a resource eater, (probably 20 main users) is it possible to have just one Zope Server and multiple instances of the database/CMF/Plone for the users? All user instances and content including the database entries would need to be accounted for in and installed in their own home directories to allow us to control and manage each user or groups bandwidth and quota's etc etc. Is this possible? If so, is there a how-to or something I have not found yet or some advice would be appreciated. I have several books on Zope now and none of them seem to describe instances or multiple user configurations in any detail. I am looking for each department/user/group to be able to manage, for the most part, their own web-services, but with us still managing the usual operating and application environments. Thanks a lot, regards, Russ

How do I override the default name of zdsock for the socket used by Zope? I see socket-name defined in Zope/lib/python/zdaemon/sample.conf but have no idea what this sample.conf is used for. -- John

[ANN] TextIndexNG 3.1.1 released
by Andreas Jung 03 Dec '05

03 Dec '05

I am pleased to announce the release of TextIndexNG V 3.1.1. TextIndexNG V 3 is a complete new implementation based on Zope 3 technologies and can be used both in Zope 2.8 or in Zope 3. What's new? - multi-field indexing and query support - multi-lingual support - configurable converters (through ZCML) - new indexing API (allowing you to hook your custom content types with TextIndexNG through Zope 3 adapters). Changes in V 3.1.1: - TextIndexNG3._apply_index() did not use the indexes default_encoding for converting non-unicode query strings to unicode - adapters for Plone content-types were not configured properly in adapters/configure.zcml - improved behaviour of the adapter for ATFile instances - minor fixes Requirements: - Zope 2.8+, Zope 3.1+ Download: http://sf.net/projects/textindexng Project page: http://opensource.zopyx.biz/OpenSource/TextIndexNG3 For installation and documentation issues refer to doc/README.txt from the archive. It's basically the same procedure as with former versions except you *need* to recompile the extension modules. Windows binaries of the required extension modules are currently not available (any volunteers?). TextIndexNG V 3 is published under the ZPL.

Hello, does anybody knows a different possibility to beware the bobobase_modification_time of the given object from the following code? def my_index_object(object, catalogs=['myPointerCatalog', 'mySearchCatalog']): for cat in catalogs: object.default_catalog = cat object.index_object() # set back to default object.default_catalog = 'Catalog' regards jens

exUserFolder will not redirect to login page
by Gaute Amundsen 02 Dec '05

02 Dec '05

Hi all. I have this problem with our zope based CMS system. No matter what i try I can not make the docLogin page appear when it should. If I go directly to it, it works fine, but otherwise the http auth poppup appears. I have started looking into exUserFolder, and putting in zLOG.LOG statements to try to figure out what is going on. The best description of what is _supposed_ to be going I have found is this: http://www.zope.org/Members/vladap/mysqlUserFolder/release-1.0.5/README Section -> "Zope authentication process" When i log just above "if user != None:" in validate at approx. line 1040 in exUserFolder.py I get: auth: None roles: None parent index.html user: Anonymous User I get this wether index html allows anonymous or not. Is this propper behavior? Where does roles come from? Should not that reflect the roles needed for access? If access is allowed all the other requests for images and so on have: auth: None roles: ('Manager', 'Anonymous') parent <bound method Image.id of <Image instance at 42aeb650>> user: Anonymous User I think our CMS has modified the permission system somewhat to allow access to some specific folders above acl_users, but I have not found those changes yet. (and the lead developer is very busy on something else, and don't remember) I don't know if this is relevant or not, either.. Anyway, it seems a crucial point must be towards the end of cookie_validate after "if not self.sessionTracking" at approx. line 930. If I override here and set roles = ('Manager'), i get to "raise 'LoginRequired'", and it seems like I should end up at acl_users/docLogin via docLoginRedirect.dtml, except that I go into a redirect loop because of the same override. Normally "if nobody.allowed(parent, roles):" is true, and "ob" is returned, which is 'Anonymous User', even if the file I am accessing is protected. Should not this be None in the last case? And if it returns anonymous, then who decides to ask the next acl_user upp the chain (who only knows http auth)? How about some way to trace down where roles come from? Am I on the right track here? I had a peek in ZPublisher/BaseRequest.py, but that only made me more confused.. All confused, and ready to give up now. Any and all explanations, tips, or good ideas appreciated.

How to Update files that are already uploaded
by Mike Jakowlew 02 Dec '05

02 Dec '05

Hi all, I'm trying to update a file thats already been uploaded. I can't figure out what command to use, "update_data"/"manage_upload"/"manage_edit". I've settled (so far) on manage_upload but it doesn't work. I get the error: Error Type: AttributeError Error Value: manage_upload my code: _________________________________________ # Takes the filename from a form searches my ZSQL method for the existence of the file, and then should update the file. REQUEST=context.REQUEST filename = REQUEST.form.get('file') filename=filename.split('\\')[-1] result=container.Show_filename_selected(filename=filename) if result: fname= container.Show_filename_selected (filename=filename).tuples()[0][3] context.manage_upload([filename,REQUEST]) return "File Exists... UPDATE: " + filename else: return "File Does NOT Exist: " + filename _________________________________________ What am I doing wrong? Am I using the wrong command? Thanks in advance, mjakowlew

MySql problems
by Dennis Allison 02 Dec '05

02 Dec '05

I have not yet completed differential diagnosis, but I was hoping someone had encountered a similar problem and could pass along a fix/workaround. The following program fails to do the writes -- import MySQLdb initdb='test' dbuser = 'root' dbpass = 'XXXXXX' host = 'localhost' connection = MySQLdb.connect( db=initdb, user=dbuser, passwd=dbpass, host=host ) cursor = connection.cursor() qd = "delete from test.data" cursor.execute(qd) qi = "insert into test.data values('ardvark', 'homework') " print qi cursor.execute( qi) q2 = "select * from test.data" cursor.execute( q2) res = cursor.fetchall() print res when run with Mysql-Python-1.2.1c under Python 2.4.2, but works just find with Mysql-Python-1.1.1 under Python 2.3.5. The tables are Innodb tables (that is, transactional). Running Zope with Python 2.4.2 and Mysql-Pyton 1.2.1c works just fine. Is there something special I need to do that I have forgotten? --

Short tutorial on I18n with Five
by Philipp von Weitershausen 01 Dec '05

01 Dec '05

I'm happy to announce that I've finally managed to document the internationalization (i18n) features that Five has brought to the Zope 2 world since version 1.1: http://worldcookery.com/files/fivei18n This short tutorial compares current Zope-2-based solutions to the i18n problem with the Zope 3 i18n framework. It also gives a few pointers on how to use the latter in Zope 2 applications through the means of Five. It is not a full-blown tutorial and it expects the reader to be quite familiar with i18n-aware software development in Zope already. Target audience is mostly people switching over their Zope 2 products to Zope 3 technology which i18n is a part of. The tutorial also serves as a documentation of a new Zope 2 core feature because Five 1.3 is included in Zope 2.9 which is thus the first Zope 2 version to come with built-in i18n support!
