Creating a session_data in another temp_folder
by Tim 04 Dec '02

04 Dec '02

I've been attempting to use the Zope 2.5 session objects within a self-contained product. I do not want to use /temp_folder, but rather this product has its own temp folder, and wants to control its own session_data parameters. I note in lib/python/OFS/Application.py (seemingly the only source of documentation <-;) that there is hard coding for creating the "session_data" transient object in /temp_folder. I have borrowed/modified chunks of that code and tried to insert it into my own product, but apparently I can't find the right place to insert it. Admittedly I'm hacking in the dark, more by trial and error than any understanding of Zope's workings. Could anyone point me in the right direction regarding how to ensure one's own product has its own temp folder with a session_data object in it, when it is created/refreshed? -- Tim Middleton | Cain Gang Ltd | Asios pummeled his thighs..."Father Zeus, x(a)veX.net | www.Vex.Net | you, even you, turn out to be a liar."

calling Oracle Stored procedure
by Michael Guerrero 04 Dec '02

04 Dec '02

All, This is my first attempt to call and oracle stored procedure. Here is my simple procedure: PROCEDURE MTEST ( p_apgt_id IN hdr.apgt_id%type) IS BEGIN insert into test (apgt_id) values (p_apgt_id); commit; END; -- Procedure I have created a 'Z Oracle Stored Procdure' called sqlproc_mtest that refers to my procedure. I also have a small dtml method to test the call: <dtml-var standard_html_header> <dtml-call "REQUEST.set('apgt_id',4444)"> <dtml-call "sqlproc_mtest(p_apgt_id=REQUEST.get('apgt_id'))"> <dtml-var standard_html_footer> When I try to view this, I get the following errors. Am I calling the procedure incorrectly? What is the best way to call an oracle stored procedure? Error Type: DatabaseError Error Value: (6550, "ORA-06550: line 1, column 14:\nPLS-00225: subprogram or cursor 'MTEST' reference is out of scope\nORA-06550: line 1, column 8:\nPL/SQL: Statement ignored") Traceback (innermost last): File /opt/Zope-2.4.0-src/lib/python/ZPublisher/Publish.py, line 223, in publish_module File /opt/Zope-2.4.0-src/lib/python/ZPublisher/Publish.py, line 187, in publish File /opt/Zope-2.4.0-src/lib/python/Zope/__init__.py, line 226, in zpublisher_exception_hook (Object: LockableItem) File /opt/Zope-2.4.0-src/lib/python/ZPublisher/Publish.py, line 171, in publish File /opt/Zope-2.4.0-src/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: atest) File /opt/Zope-2.4.0-src/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: atest) File /opt/Zope-2.4.0-src/lib/python/OFS/DTMLMethod.py, line 194, in __call__ (Object: atest) File /opt/Zope-2.4.0-src/lib/python/DocumentTemplate/DT_String.py, line 544, in __call__ (Object: atest) File /opt/Zope-2.4.0-src/lib/python/DocumentTemplate/DT_Util.py, line 230, in eval (Object: sqlproc_mtest(p_apgt_id=REQUEST.get('apgt_id'))) (Info: REQUEST) File <string>, line 2, in f (Object: guarded_getattr) File /opt/Zope-2.4.0-src/lib/python/Products/ZOracleDA/SP.py, line 150, in __call__ (Object: sqlproc_mtest) File /opt/Zope-2.4.0-src/lib/python/Products/ZOracleDA/DCOracle2/DCOracle2.py, line 1099, in __call__ (Object: MTEST.MTEST) File /opt/Zope-2.4.0-src/lib/python/Products/ZOracleDA/DCOracle2/DCOracle2.py, line 743, in execute DatabaseError: (see above) Thanks.

Query on WebDAV Lock Manager.
by Paul Naveen Raj Jeyaraj 04 Dec '02

04 Dec '02

Hi, While editing contents under zope, will it be locked by the WebDAV Lock Manager automatically or does it require some coding to implement the same? I created a sample DTML document and tried to edit it accessing through two browsers and was able to succeed. How can I block one user from editing the content when it is being edited by someone else? Please help if you have some idea on how to go about. Regards, Paul.

Newbie ZClass confusion
by toman 04 Dec '02

04 Dec '02

Hi, I'm a little confused about ZClass construction. I have a product 'Lucy' which has folderish ZClasses 'bob' and 'bill' in it. Each instance of a bob should be constructed with a bill named 'Willliam' in it. The default DTML method bob_add has the following snippet: <dtml-with "bob.createInObjectManager(REQUEST['id'], REQUEST)"> <dtml-comment> ... </dtml-comment> </dtml-with> Where and how do I construct the bill ? My naive thought was to put a <dtml-call "bill_add(id='William')"> in the dtml-with statement, but that doesn't seem to work. Suggestions? I've read 'The Zope Book' a couple times, looked through ZopeLabs and didn't see anything like this except for adding a folder, which isn't that helpful because they're a standard class and have various management methods defined for them. Ideas? J. Toman

Help! I need an old Debian package.
by Kyler Laird 04 Dec '02

04 Dec '02

Zope on our main server was upgraded to the Zope 2.5.1 recently. When I restarted, everything was broken. I have fixed the main problem, but now the TransparentFolder product isn't working. I'm screwed without TransparentFolder. I *really* need to get that working. I suspect I need to downgrade to a 2.4.x Zope. Anyone know where there's a Debian package of it? Thank you! --kyler

Simple worked example for ZPT forms
by Sam Hunting 03 Dec '02

03 Dec '02

Hi-- I'm finding the example of the form/action/response pattern in Chapter 9 of the Zope book a little opaque, because some of the pieces are missing and (as a newbie) I don't know which ones. Can anyone point me to a complete worked example? From the request form, through the scripted action, to the response. I'll take care of getting it into the book, if someone will post it here.

folder name problem
by Ben Avery 03 Dec '02

03 Dec '02

Hi, using Zope 2.6.0 with Python 2.1.3 on Solaris 7, I come across the following strangeness: I have a folder called 'hq'. Inside this I want to add another folder called 'manage'. there is nothing inside hq called anything like manage. When I try to add the folder, I am told that this is a bad request, because the id 'manage' is already in use. It clearly isn't in use in this folder. Is this some kind of reserved word in Zope? thanks Ben Avery YouthNet UK

Problem with next on SQL queries
by Blurg 03 Dec '02

03 Dec '02

Everytime I get a request on the database in Zope (MySQL) which receives more then 20 results, I can't click on the "next 20 results" link, and I get this error: Invalid request The parameter, query, was omitted from the request. Make sure to specify all required parameters, and try the request again. Ehm, I think Zope needs the query again, but it's not there in the link, the link points to http://usr-bin.com/123/manage_test?query_start=21 I think my Zope can't find the qeury_start object anymore or something? Thanks so far, Jurgen --------------------------------------------------------------------------- "When a man sits with a pretty girl for an hour, it seems like a minute.

LocalFS and catalogs
by Isokangas, Erik HTC/DE/FRA 03 Dec '02

03 Dec '02

Hi, I'm struggling a bit with the product LocalFS and hoping someone can point me in the right direction. LocalFS installs and seems to work fine out-of-the-box. However, I would like to catalog each file (and contents of each file) in the file system being served. The properties of my LocalFS object has a "catalog" option which claims to catalog files in the filesystem. However, this doesn't seem to do anything. I'm using Zope 2.6.0 on Suse8.0 Linux. I have a Zcatalog object installed with only two indices (fulltext, keywords) - no metadata fields currently defined. What is the process that LocalFS uses to catalog files in the filesystem? How does LocalFS know which catalog, indices, metadata to use, etc.? Thanks for your replies, Erik Isokangas

Making a Z Class and a Z Catalog get along - PropertyManager?
by Edward Pollard 03 Dec '02

03 Dec '02

I've managed to succesfully create my Z Class product so that it enters itself into the Z Catalog on creation. Hooray for me. Now, the goal of this task I'm undertaking is to allow web pages to have specific properties associated with them, and these properties are automagically searchable. That is why I made the Z Class which is based in PageTemplate, as it needs to behave pretty much like a page template, but have two properties that are searchable. Now, I've seen it mentioned in passing that the PropertyManager is not catalog aware, and as such I'm not so surprised to learn that the objects I create do not have their changes to their properies reflected in the Catalog. Where I saw this mentioned was a post to the effect of "Make sure you make PropertyManager catalog aware!" How do I make PropertyManager catalog aware, and only aware for this specific ZClass? As a more general question: Can anyone direct me to some Zope resources suitable for intermediate questions such as this? I have the Zope Book in front of me, but that only covers the basics, and I can't find much in the way of usefull information on Zope.org. (Or is that just me?) Anything else out there so I don't have to wander around asking silly questions? Ed
