Sorry-- Python 2.3.4 is what I meant. But this question would really apply to any version of python to be installed that applies to the system python. Thanks for the suggestions-- I do believe that I now know how to install multiple versions of python on one machine. I will test on a development machine prior to deployment on production.

Re: Hierarchical content
by Ken Ara 17 Jan '05

Greg, A nifty way to create a folderish hierarchy is by using the TopicIndex class of the DocumentLibrary product. You simply import a tabbed-indented outline such as that found here: http://zope.org/Members/Kaivo/DocumentLibrary/1.0/LegalTopicIndex.txt You can even leave out the numeric ids in the sample; sequential ids will be assigned automatically.

perhaps an rpm -Uvh rather than an rom -ivh is a better idea when upgrading? also try uising the built in tools for upgrading ... these are usually specific to your distribution .. mandrake have urpmi, suse have yast and redhat have something else? tariq -----Original Message----- From: hpinson(a)indepthl.com [mailto:hpinson@indepthl.com] Sent: 16 January 2005 04:43 To: zope(a)zope.org Subject: [Zope] Python 2.3.3 vs. Python 2.3.4 Hi.

form and zpt question
by Haim Ashkenazi 16 Jan '05

16 Jan '05

Hi I'm looking for a way to pass the values entered in a form (zpt) back to the same page after processing it in a python script. say I have this zpt: ---- <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html metal:use-macro="container/index_html/macros/page"> <td metal:fill-slot="body-content"> <h2>Add a new Client</h2> <p> In the form below, you can add New client. the "price" fields (if filled) will be used for calculations in the reports.<br> Please make sure that you check that the client do not exist in the list below! two names of the same client can cause problems when producing reports.<br> </p> <ul> <li>Already defined customers:&nbsp&nbsp <select name="customer"> <option tal:repeat="clients container/show_clients" tal:content="clients/name">Clients</option> </select> </li> </ul>  <p tal:condition="options/error_message | nothing"> <font color="Red"> ERROR:&nbsp <em tal:content="options/error_message">error here</em> </font> </p> <form action="add_client.py" method="post" onSubmit="return validateStandard(this);"> <table cellpadding="5"> <tr align="left"> <th>Customer name:</th> <td><input name="customer" ></td> </tr> <tr align="left"> <td>Price - on site:</td> <td><input name="onsite" size="5"></td> </tr> <tr align="left"> <td>Price - remote:</td> <td><input name="remote" size="5"></td> </tr> <tr align="left"> <td>Price - phone support:</td> <td><input name="phone" size="5"></td> </tr> <tr align="left"> <td><button name="submit" value="submit">Submit Customer</button></td> </tr> </table> </form> </td> </html> ------------------------ and this script: -------------------- ##parameters=REQUEST ##title= ## # parse input from "addclient" form and returns the result. req = REQUEST # if no name was specified if not req.customer: return container.addclient(error_message = "You must specify the customer's name") context.add_client(name = req.customer, onsite = req.onsite, remote = req.remote, phone = req.phone) response = container.clientsubmited(name = customer) return response ---------------------- in case of an error, it re-renders the template with the error above. this works fine, but I want it to keep the values already entered in the form, not to give me a blank form. one way to specify them when calling the template from the script, but in large forms this will result in a very long parameter list. is there one object that holds all the values that I can pass back to the template? thanx -- Haim

Apache and Zope
by Robert Hill 16 Jan '05

16 Jan '05

This question may be more appropriate for the Apache mailing list, but it is Zope-related so I figured I'd check here as well. I'm trying to set up Apache HTTP Server to run in front of three sites on my server. Two of which are Zope sites and one of which is a PHP app that is hosted by Apache. I've got three different URLs pointing to the IP address of the server. The setup is something like this: Zope Site 1 - Actual address: www.mysite.com:1234/zope1 Virtual Host: zope1.mysite.com (Zope is running on port 1234) Zope Site 2 - Actual address: www.mysite.com:1234/zope2 Virtual Host: zope2.mysite.com PHP Site - Actual address: www.mysite.com:7777 Virtual Host: php.mysite.com Now here's the frustrating part - I've got it working perfectly as long as I'm accessing these sites from the server. The problem is, whenever I try to access zope1.mysite.com or zope2.mysite.com from another machine, it sends me to php.mysite.com. Any ideas? Here's my virtual host configuration: NameVirtualHost zope1.mysite.com:80 <VirtualHost zope1.mysite.com:80> ServerName www.mysite.com RewriteEngine On RewriteRule ^/(.*) http://127.0.0.1:1234/VirtualHostBase/http/zope1.mysite.com/zope1/VirtualHo… [L,P] </VirtualHost> NameVirtualHost zope2.mysite.com:80 <VirtualHost zope2.mysite.com:80> ServerName www.mysite.com RewriteEngine On RewriteRule ^/(.*) http://127.0.0.1:1234/VirtualHostBase/http/zope2.mysite.com/zope2/VirtualHo… [L,P] </VirtualHost> NameVirtualHost php.mysite.com <VirtualHost php.mysite.com> ServerName www.mysite.com RewriteEngine On RewriteRule ^/(.*) http://127.0.0.1:7777/$1 [L,P] </VirtualHost>

ZODB packaging behaviour: bug or feature?
by Ausum Studio 16 Jan '05

16 Jan '05

(sorry about the HTML encoding of my previous post) Use case: Create a new Zope instance. Perform some changes and then pack the database to remove objects revisions older to 0 days. You want a clean instance to start with. Now create a cron job to daily pack the database to remove objects older to 14 days, and start to use your instance. Zope won't pack the database at all, and I guess it will be for the first 2 weeks, because it won't find revisions older to 14 days during that time. Is that normal behaviour? Telling by the interface text at the Database Management tab, it looks like the command would create a Data.fs.old file even though there weren't older revisions than the number set, meaning that by default the packing would create an exact copy of the current Data.fs (to keep all changes), at least until there were revisions to remove. The problem is that if you rely on Data.fs.old for backup purposes, you'll find that your 13th day Data.fs.old is exactly as that of day one. An even though you had never packed the database to 0 days, the problem would come up if, for any reason, you feel like it's time to manually pack the database to 0, in between those two weeks. Your cron job won't modify the existing Data.fs.old for the following two weeks. Am I missing something? Thanks in advance, Ausum

Complex SQL query
by Jos� Monte 14 Jan '05

14 Jan '05

Hit here. I'v 2 databases (GadFly) that have different data. I wish to join some data using a ZSQL method. I have something like: SELECT table1.colum1, table2.colum1 FROM table1, table2 WHERE table1.colum1 = table2.colum1 Until this step everything is working fine... The problem appears when I want to compare the result of the above query (taht is working ok) with some data that only exists in the table2 and in table1. I want to get some data from the table1 that I compare in table2 (table1.colum1 = table2.colum1) and them I only want the data that the in the table1.colum1 is equal to 1 and 2 and in the table2 where above 0 (zero) in the colum2 and the colum3 < than the actual date. I try to put something like: SELECT table1.colum1, table2.colum1 FROM table1, table2 WHERE table1.colum1 = table2.colum1 AND table2.colum2 > 0 AND table2.colum3 < <dtml-var expr="_.float(_.DateTime())"> AND table1.colum1 = 1 OR table1.colum1 = 2 This query is getting ZOPE to time out and it only works again with a restart... Can anyone help me with this? Thanks a lot, José Monte P.S. - sorry for my extremely bad english. _________________________________________________________________ Express yourself with cool new emoticons http://www.msn.co.uk/specials/myemo

RE: [Zope] Undo problem
by Pascal Peregrina 14 Jan '05

14 Jan '05

Ok, I am using Zope 2.7.3, which includes ZODB 3.2.4 In the code below, I am not doing any transaction handling by myself. When I modify A properties, the call to the B method (that modifies B PersistentMapping) is made from the method of A that actually modidies A pesistent data. So why wouldn't A and B object changes be part of the same transaction ? Is there any explicit code to make sure to remain in a single transaction ? Thanks.

When the change to A and B happens in the same transaction, then the undo must revert both changes. If it does not, you hit a bug. Note that in older Zope versions, invalidation messages were not sent correctly for "undo" (from ZEO).
