It could be done, but it would require changing the data structures since the weights would be applied at query time but would need to be stored at index time. Actually being able to weight objects arbitrary might be pretty interesting. It would allow you to pull tricks like Google and make certain results always rate high for certain queries. I'm not sure if that's what you were thinking but it could be a pretty cool trick. > Oh, and I'm noticing FieldedTextIndex uses Okapi ONLY ?

Doing both would be pretty complex and I didn't think it was worth the effort since I always use Okapi myself. I'm going to call YAGNI on this for now. > Phew, sorry, I'm babbling ...

Problem inserting <dtml-var sequence-item> using ZSQL method in a dtml-in tag
by Gabriela LÃ³pez Ruiz 14 Jan '04

14 Jan '04

Hi all, I'm here again. Now I have a problem trying to insert a group of records in a relational table. I'm using ZSQL and the fact is that in the second column (statement_template_id) I need to insert the actual value of the sequence-item. But I can't use it in the dtml-call tag. When I print it in the HTML table, the value is ok but I need to insert that value in the statement_template_id. How can I get the sequence_item value to insert it in the table? <dtml-in actual_boolean_value> <td><tr> <dtml-var actual_boolean_value><dtml-var sequence-item> </td></tr> <dtml-call "updateStatementValues( checklist_id=_['checklist_id'], statement_template_id=<dtml-var sequence-item>)"> </dtml-in> Thanks a lot for your suggestions. Gabriela. _________________________________________________________________ Charla con tus amigos en línea mediante MSN Messenger: http://messenger.latam.msn.com/

Cookie Crumbler - Help modifying source
by Samir Mishra 14 Jan '04

14 Jan '04

Hi all, I'm using Cookie Crumbler to authenticate users. On login failure, or success for that matter, Cookie Crumbler strips the request of all info. What I'd like it to NOT do is delete cookies I'm setting just before the user is required to login. I believe I'll have to modify the source code to be able to do this. I'm hoping someone could help me modify the source, and if there's a better way to go about achieving this, suggestions will be appreciated. Thanks in advance. Samir.

ZODB A storage error occured during transaction abort.
by Dennis Allison 14 Jan '04

14 Jan '04

Dieter, Your lucid description of the source of the "AttributeError: Surrogate instance has no attribute '_p_oid'" error in the mailing list archives explains what's happening, but I am at a loss to identify the method that registers the surrogate and does not have an _p_oid instance. My problem is trying to identify the source of the failure. There are a couple of external procedures used in the QLOG method which caused the conflict error, but nothing other than vanilla DTML nearby in the log. Do you have any suggestions for localizing the problem? This is all running on Zope 2.6.2b3, Python 2.3.1, RH7.3. ------------------------------------------------------------------- >From the error log: 2004-01-13T17:15:21 ERROR(200) ZODB A storage error occured during transaction abort.

Zope install/startup problems on Debian Sarge
by Goran Christiansson 14 Jan '04

14 Jan '04

Dear All, I have installed Zope on Debian Sarge (testing), but I cannot log into the ZMI. I got the package using "apt-get install zope", created an instance using: > zopectl init default > zopectl access default (I made a password using the zpasswd.py script) > zopectl restart The instance seems to start all right. On port 9673 I get the Zope introduction text. However, when I try to access /manage, I get a Error 500 page in my browser. The detailed log file contains: U 000000000 2004-01-14T21:51:01 System startup B 150241180 2004-01-14T21:51:06 GET /manage I 150241180 2004-01-14T21:51:06 0 A 150241180 2004-01-14T21:51:06 401 705 U 000000000 2004-01-14T21:51:07 System startup B 150240820 2004-01-14T21:51:15 GET /manage I 150240820 2004-01-14T21:51:15 0 A 150240820 2004-01-14T21:51:15 401 705 U 000000000 2004-01-14T21:51:16 System startup B 150240764 2004-01-14T21:52:10 GET /manage I 150240764 2004-01-14T21:52:10 0 Where should I start looking?

LDAP - Zope - ACLUsers &- Manage Local Roles
by Julian Clark 14 Jan '04

14 Jan '04

Hi List. I've recently recreated a zope installation that someone else built, in the process updating to zope 2.6 from 2.3.3 I'm not having much joy with LDAP + local roles upon the manage local role interface. I've discovered in the dtml source for listLocalRoles there is a try/except for overflow, which is being caught and therefore not bringing the list of users up. Does this mean that my ldap server is returning too many results? It works properly on zope 2-3-3 without a try/except statement. Is there something else I can do to stop the overflow error? I feel that with this out of the way, everything else will work properly (I hope) When I manually enter a user name and assign a local role, then attempt to test it, the LDAP log shows a successful authentication, however, I'm still getting unauthorized errors. :( this is an extract from the LDAP log.. (9) Mon 11:51: Checking julcla (9) Mon 11:51: julcla not found in user cache (9) Mon 11:51: Opened connection to ldap server (9) Mon 11:51: Closed connection to ldap server (9) Mon 11:51: julcla connect returned cn=Julian Clarke (julcla),ou=people,dc=b-online,dc=com,dc=au,o=internet (5) Mon 11:51: julcla user authenticated (9) Mon 11:51: Checking julcla (9) Mon 11:51: julcla found in user cache (7) Mon 11:51: julcla authenticated from cache (9) Mon 12:02: Checking julcla (9) Mon 12:02: julcla found in user cache (7) Mon 12:02: julcla authenticated from cache Which gives me the impression that I should be able to login from here. However, I am continuously prompted for username & password, which always fails, when I cancel, I get these errors...

Just so you know ;) This looks like you're not getting the plone css files from the server, which would happen if plone/zope sent you to the wrong URL for those files. Check the source code for the page to see where the server is sending you Please recheck the configuration in the ASP404 script. Also check that you only have one VirtualHostMonster in the root of your Zope (not inside plone. I don't know if it's a problem, but I haven't checked). If you're using a binary plone release, that has two web ports open, one for Plone and one for Zope (administrative port), check that you're connecting to the administrative port (i.e., you're accessing the port that gives access to the Zope root), and configure ASP404 to access the plone folder inside it. Cheers. -- Ideas don't stay in some minds very long because they don't like solitary confinement.
