Hi. I found out what my problem is. in my code I please baseclass Item before Folder class ShpProjectClass(Item, Folder, Persistent, Implicit, CatalogAware): when I change the order, it worked normally class ShpProjectClass(Folder, Item, Persistent, Implicit, CatalogAware): but I don't understand why? could someone explain this to me? ----- Original Message ---- From: Allen Huang <swapp0(a)yahoo.com> To: Zope <zope(a)zope.org> Sent: Monday, March 12, 2007 10:31:27 AM Subject: Re: [Zope] have problem with managing objects within a external product Dear AJ, Thanks, but I still have some problems with creating a Folderish Object product I imported Folder from OFS.Folder but I wasn't able to add any products like File, Folder, Image with in my folderish object. my code looks like this--> class ShpProjectClass(Item, Folder, Persistent, Implicit, CatalogAware): id = 'ShpProject' meta_type = 'ShpProject' manage_options = ( {'label':'Contents', 'action':'manage_main'}, {'label':'Properties', 'action':'manage_editShpProjectForm'}, {'label':'View', 'action':'index_html'}, ) + Item.manage_options def __init__(self, id, projectDesc = 'Test Project'): """ Initialize a ShpProject Object """ self.id = id self.projectDesc = projectDesc def getProjectInfo(self): """ print a ShpProject Object Info """ return 'This project is called: ' + self.id + '.

For folderish content you derive from ObjectManager or for being on the safe side from OFS.Folder from OFS.Folder import Folder class MyType(Folder): meta_type= 'MyType' .....

Redirecting
by tonylabarbara＠aol.com 13 Mar '07

13 Mar '07

Hi; I have a Web site I'm building a shopping cart for that is built with a basic site template and an iframe where all the page-by-page info goes. I need to redirect the iframe to the address below, but when I use the current incantation, it replaces not just the iframe but the whole page! Can someone suggest a better idea? This is a python script: request = container.REQUEST response = request.RESPONSE response.redirect(request.BASE0 + '/EMarket/Our_Store/Main_frame.pt?category=' + category) TIA, Tony ________________________________________________________________________ AOL now offers free email to everyone.

Data.fs & MySQL DB Blown Up!
by tonylabarbara＠aol.com 12 Mar '07

12 Mar '07

Hi; Forgive the long (but necessary) background. I bought a new 500 GB hard drive for my server located on the other side of the world. I accidentally entered an erroneous command to copy everything from the old HD to the new one and ended up corrupting the OS. However, the *first* thing that happened was that command zapped my Data.fs. It was located on the new HD with a symlink for the entire var dir going from the old HD to the new one. Fast foreward to this week. I've built a new server and transplanted my 500 GB HD. I told the server farm to check it thoroughly because I suspected the hardware may have gotten corrupted. They swear they did check it thoroughly. I have 2 Zope instances. On one, I moved the var to the new HD with the symlink. I also moved my MySQL database to the new HD. I left them alone while I was working on the other Zope instance. Lo and behold, without my doing anything, suddenly the Data.fs on the Zope instance on the new HD got rewritten to 0 bytes and the MySQL database got completely nuked! My server farm tells me it has nothing whatsoever to do with the hard drive or the OS, that both are in perfect condition. I say that's nonsense! What do you think?

Installation problems
by Calder Coalson 12 Mar '07

12 Mar '07

Hi, I'm attempting to install Zope on Mac OS X and having problems. I'm sure the documentation is sufficient for most people, but I really don't understand how to run Zope. I performed the install instructions, (correctly, I think). I've got a Zope folder in my home directory, and a Zope-3.3.1 folder in /usr/local, but from what folder do you actually run ./start to start the server? It says your installation directory. i assumed that meant /usr/local/Zoper-3.3.1, but that didn't work. Then I tried ~/Zope: didn't work. And as a last desperate attempt, I tried ~/Zope/Zope: no results. In all cases I got: tcsh: ./start: Command not found. Help for the one stupid guy on this list will be much appreciated. ;-) Thanks, Calder Coalson

Two mysql / timestamp related fixes
by Gaute Amundsen 12 Mar '07

12 Mar '07

Hi. Just had som troubles when I added timestamp columns to a table. Commnets? my setup: Mysql: 4.1.20-log Zope Version: (Zope 2.7.5-1.fc3, python 2.3.4, linux2) 1 ) First I got a ValueError 'query' when using a very simple zsql method. (consisting of only "<dtml-var sql >") (I am not totally sure this is related to the timestamp column) I appled the fix to customDefaultReport.dtml mentioned in http://mail.zope.org/pipermail/zope-db/2005-June/004219.html < <a href="&dtml-URL;?query_start=&dtml-previous-sequence-start-number;&query=<dtml-var query url_quote>"> --- > <a href="&dtml-URL;&dtml-sequence-query;query_start=&dtml-previous-sequence-start-number;"> 25d24 < <a href="&dtml-URL;?query_start=&dtml-next-sequence-start-number;&query=<dtml-var query url_quote>"> 26a26 > <a href="&dtml-URL;&dtml-sequence-query;query_start=&dtml-next-sequence-start-number;"> This does not seem to be exactly the same fix as described in: http://www.zope.org/Collectors/Zope/1812 Should I have this problem in Zope 2.7.5-1.fc3? 2) ValueError: invalid literal for int(): 0- When trying to do a "select *" this is definitely connected to the timestamp column, because this change fixed it: diff /usr/lib/zope/lib/python/Products/ZMySQLDA/db.py /usr/lib/zope/lib/python/Products/ZMySQLDA/db.py~ 173d172 < conv[FIELD_TYPE.TIMESTAMP] = DateTime_or_None I have found no mention of this anywhere? Have anyone else had this problem Comments? Regards Gaute Amundsen
