CatalogAware ZClass with File base class
by Fusion Group 02 May '00

02 May '00

I wanted to make my new File objects CatalogAware so I created a new ZClass with CatalogAware and File as my base classes (in that order). When I upload a new file, calling manage_addFile from my ZClass, it of course is not made available for my Catalog. I know I'm doing this wrong, but I'm starting to run out of time on this project and can't afford the luxury of fiddling until I figure it out anymore. I probably should have fiddled with Zope a little before I used it for a client's project, but it's too late now. Any help would be greatly appreciated Regards, Chad

Zope & Z39.50
by Eron Lloyd 02 May '00

02 May '00

Is there anyone that has been successful at using Zope and Python to access resources of another database (Like a Library Automation System) using the Z39.50 protocol? I haven't been able to find much of anything on this; I know Z39.50 is not widely used for general Web communication. I also wonder how hard it would be (if a solution doesn't exist) to implement this in Zope, possibly by building a Z39.50 protocol toolkit in Python and then plugging it into Zope. Eron

Zope vs Apache benchmarks
by Hugo Ramos 02 May '00

02 May '00

Yellow, I've tested Zope and Apache on the SAME MACHINE Because of the Zope rendering on all objects before serving the request I've done a php script that reads an .html file and serves the output. Command used: ab -n 100 -c 10 <url> I didn't like the results!!!! RESULTS: APACHE Server Software: Apache/1.3.12 Server Hostname: 192.168.0.128 Server Port: 80 Document Path: /ger.php3 Document Length: 47349 bytes Concurrency Level: 10 Time taken for tests: 0.370 seconds Complete requests: 100 Failed requests: 0 Total transferred: 4751600 bytes HTML transferred: 4734900 bytes Requests per second: 270.27 Transfer rate: 12842.16 kb/s received Connnection Times (ms) min avg max Connect: 2 13 26 Processing: 29 22 14 Total: 31 35 40 ----------------------------------- ZOPE Server Software: Zope/Zope Server Hostname: 192.168.0.128 Server Port: 8080 Document Path: /rfc.html Document Length: 47349 bytes Concurrency Level: 10 Time taken for tests: 1.736 seconds Complete requests: 100 Failed requests: 0 Total transferred: 4802954 bytes HTML transferred: 4782249 bytes Requests per second: 57.60 Transfer rate: 2766.68 kb/s received Connnection Times (ms) min avg max Connect: 0 26 163 Processing: 42 137 130 Total: 42 163 293 ---------------------------------------- I think Zserver didn't actually give a very nice image of Zope!!!

dtml-in ???
by Pierre Rougier 02 May '00

02 May '00

Hi, Finally, for printing my index_html method, I use the read_raw() method. but I still have a problem: <dtml-in "objectItems('DTML Method')" sort=id> <dtml-if "id == index_html"> <dtml-var "read_raw()" html_quote> </dtml-if> ... </dtml-if> ...... ...... </dtml-in> As u can see, I want to test if the methods I extract from the methods that exists have special names, to treat it in different manners. Problems is that the <dtml-if "id == index_html"> test does not seem to work.... It can sound a very simple syntax question, but how can I test the method name??? I tried the tag <dtml-var id> which gave me the good method names... Can u help me??? Thanks a lot Pierre

Re: [Zope] standard_error_message
by Ray 02 May '00

That's what I would think, but it doesn't seem to work. The header and footer work just fine, but not the standard_error_message. For example, I modified the root standard_error_message to contain the words "This is the root". Then created a folder called Testing, copied the same standard_error_message document into that folder and added the words "This was copied from..." in the beginning of the doc. I even restarted the server, just to be safe. When I still went to http://server/Testing/badfile, I got the error message from the root. That's why I figured, perhaps, when looking for the 'badfile', the namespaces were searched all the way down the tree. When it didn't find it anywhere, it just printed the error message from where it ended up, which was at the root. Makes sense to me.. Course I'm not sure how it all really works internally. -Ray ----- Original Message ----- From: "Christian Scholz" <cs(a)comlounge.net> To: "Ray" <zopelist(a)circle17.com> Sent: Monday, May 01, 2000 6:17 PM Subject: Re: [Zope] standard_error_message > Hi! > > On Mon, May 01, 2000 at 05:49:24PM -0600, Ray wrote: > > Quick question about error messages under Zope 2.1.0 under Linux: > > > > Is it possible to overload the standard_error_message document, or do all > > errors essentially come from the root of the tree?

ZSQL method problems in 2.1.6
by John Chandler 02 May '00

02 May '00

Further to the recent discussion about problems with 2.1.6, we applied the patch to a server this morning and it appears to have fixed most of the problems. However, we're still suffering from one: The upshot is that when a ZSQL method is called and there is a variable in the namespace that matches the parameter name case insensitively, the variable is automatically used in preference to an explicitly defined parameter. So, if I have a ZSQL method with a parameter ID called as thus: <dtml-in "zsql_foo(ID=parentID)"> it will use parentID *unless* ID, id, Id, or iD exist in the namespace, in which case they are used in preference. This is annoying. At first I put this down to the problems with nested dtml-ins still remaining, but after some checks this doesn't look to be the case. Anyone else noticing problems still?

Re: [Zope-dev] (no subject)

Yes and no. If you want this to happen on a standard property sheet view, no. But you can do anything you want if you make a custom property sheet. 1. Make a DTML method that has a form that uses the values on the property sheet. To make an INPUT password-like, use type="password". 2. To put the management tabs at the top, so it looks just like the other management sheets, start your DTML method with: <html><head><title><dtml-var id></title></head> <body bgcolor="#FFFFFF" link="#000099" vlink="#555555"> <dtml-var manage_tabs><p> 3. Under "views" in your ZClass, attach that method to whatever you want to name the management tab. hth, -- Jim Washington Sergey Trofimov wrote: > > Hello Zopistas. > > Is it possible to assign password-like text fields for string > properties in property sheet of ZClass?

ZopeFind and permissions?
by julio dinis 02 May '00

02 May '00

Hi Zopistas! I have a python method in a zclass that uses the same code ZCatalog uses in the feature "Find Items to This Catalog", in order to find some objects according to a search criteria I want. When a instance of my zclass uses this code it works ok. But I must be superuser. Dont get me wrong, this is not a permission problem because I dont get any netscape authentication window, the script executes but dont find nothing. But If I am superuser the script finds objects. Even with a user with manager role the dont find objects. I've tryed all proxy and permissions options to give manager, owner, etc, and nothing :-( I've even tryed with an external method, but If I'm not superuser the script executes in a silent strange way and dont return the objects it returns if I'm superuser. Any help? Thanks. Júlio ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com

RE: [Zope] "free" personal web sites that use Zope?

Sorry, Skip. I can't say as I've heard of any 'free' Zope hosting services. There was one for about $10 mo so a year of that is about the same price as a little league bat! Like they say in the sporting goods store, 'consider it an investment.'
