one external method calling another; what possibilities?
by Fred Yankowski 07 Oct '00

07 Oct '00

I'm using some example code that defines an External Method to process a form. That External Method calls another utility function to log some data. I'm not quite sure what choices I have for creating that utility function, so I created another External Method for it. Both functions are in the same Python source file in the Extensions folder. Anyway, the main external function calls the utility function like this: self.function2(arg1=valuex, arg2=valuey) I expected that function2 would have to be defined like this: def function2(self, **kwargs) but it turned out that that fails at runtime with a complaint about a mismatch between the number of arguments sent and expected (0 and 1, respectively). The following does work: def function2(**kwargs) So, why isn't function2 called as a method function? Was there some better way I could have implemented function2, rather than as an external method? Where is reference documentation on External Methods? I couldn't find anything other than a very cursory overview in one of the PDF'ed documents (I forget which). -- Fred Yankowski fred(a)OntoSys.com tel: +1.630.879.1312 Principal Consultant www.OntoSys.com fax: +1.630.879.1370 OntoSys, Inc 38W242 Deerpath Rd, Batavia, IL 60510, USA

Zope with Apache
by James Howe 06 Oct '00

06 Oct '00

I asked this question a couple of months ago but received no response, so I figured I would ask it again to see if anyone can answer the question... We are running Zope behind an Apache server. We've got things configured so that it mostly works. However, we noticed that the "breadcrumbs" list at the top of a workspace screen doesn't work correctly. For example, if I'm looking at the object /Foo/Bar/Baz, the list of items in the breadcrumbs might look like this: DTMLDocument at / Foo / Bar / Baz The links to Foo and Bar do not correctly take into account the extra item needed to tell Apache that the link goes to the Zope site. For example, the link to Foo needs to say something like http://foo.bar.com/Zope/Foo/manage_workspace instead of http://foo.bar.com/Foo/manage_workspace The tabs for the management screens work fine, however. In looking at what is happening, I believe the problem exists because the links in the breadcrumbs line are relative links. The link to "foo" would look like this: <a href="/foo/manage_workspace">Foo</a> instead of <a href="http://foo.bar.com/Zope/Foo/manage_workspace> When I open the page, the URL I give my browser is "foo.bar.com", but my Proxy settings in Apache redirect the request to "foo.bar.com:8080/Zope". When my browser sees the relative path, it prepends the "foo.bar.com" instead of "foo.bar.com:8080/Zope" because it doesn't know any better. I've managed to get around the problem by changing some code in the tabs_path_info method found in Management.py. Basically I modifed the code to prepend "BASE0" to each of the items in the breadcrumbs list. This way, I get absolute links instead of relative. However, I'm wondering if there is just some additional configuration I need to do in Apache to fix this problem without modifying Zope itself. Has anyone else encountered this and is this a bug in Zope, or is this simply a configuration issue that I need to resolve. If its a configuration issue, what would I need to change. Any help would be appreciated. Thanks. James W. Howe mailto:jwh@allencreek.com Allen Creek Software, Inc. pgpkey: http://ic.net/~jwh/pgpkey.html Ann Arbor, MI 48103

SiteAccess2, Zope 2.2.2, __no_before_traverse__
by Olivier Deckmyn 06 Oct '00

06 Oct '00

Hi all, What is the new way to apply the "__no_before_traverse__" using SiteAccess2 ? When I was younger, in SiteAccess1, I used to postfix my URL with this (ex : http://mysite:8080/__no_before_traverse__/manage ), so that SiteRoot did not apply ; this enabling to play with the management interface on a broken SiteAcces configuration... What is the "nowadays way to to this (TM)" ? Please help ! Thanx ! --- We are Micro$oft. You will be assimilated. Resistance is futile.

Fwd: Re: [Zope] Zope in Windows is faster than Linux ???

Are you using Zope behind apache under Linux? Or it's a direct request to ZServer? As I can see the files are not the same, try to bench exactly the same file...

You need to set an environment variable and restart zope, see the siteaccess2 documentation on zope.org for more details. -Simon
