Apparently, the script needs to be called *before* the folders. I had put it at the end. Okay, that works, so now how do I incorporate it? I'm running into trouble here. I've rewritten the following line several times, and several times gotten it wrong. Perhaps you could steer me right? <div align="center" tal:define="mycontext python:`here.traverse_subpath`" tal:condition="here/hasSearchEngine(mycontext)"> TIA, Javier ____________________________________________________________________________________ Do you Yahoo!?

From: Jonathan <dev101@...> >What version of zope are you running? (I am running zope 2.9.2 on a linux box). 2.7.8 I didn't put it in 'root' since root isn't automatically called. I put it in a folder called 's' which is automatically called, then I also explicitly called it in the URL. Obviously, if the fn weren't found, Zope would have complained. It was in fact found.

Permissions problem
by Jose Carlos Balderas Alberico 11 Dec '06

11 Dec '06

Greetings. I'm having a few problems with a mini application I recently developed with Zope. It has to do with the permissions settings. The idea behind my application is that it will only be used by one person. This person has his own username and password (there is an ACL Users folder within my application's folder, with this person's name, password and role). My applicaction's directory hierarcy is as follows: ---- Application main folder. ---- Pages ---- Lib ---- Python ---- SQL methods The Application main folder has "View" permission for the role to which the user in the ACL Users folder belongs. Everything seems to work right at first. This user is able to access the index page of the application,... but when he tries to navigate to a specific page (let's call it "main_gestion_html", he gets an insufficient permissions message. The problem may lay in the fact that "main_gestion_html" uses data session variables, and most important of all, python methods from another application (let's call it ZVVB2), which is located outside the Application main folder. I tried creating a new ACL user in this other ZVVB2 folder... but I still get the same access denied message. I really need help on this. I've been stuck with this for the last few days and I don't know what else to try. Any input will be highly appreciated. Thank you so much for your time. Jose Carlos.

Page template issue?
by Eron Lloyd 10 Dec '06

10 Dec '06

Hi all, I believe I've stumbled on a significant bug, but wanted to check before reporting to the collector. When attempting to edit a page template through WebDAV (in my case using KDE/Quanta+), I get an error, and Zope's error_log reports the following error: Traceback (innermost last): - Module ZPublisher.Publish, line 115, in publish - Module ZPublisher.mapply, line 88, in mapply - Module ZPublisher.Publish, line 41, in call_object - Module Products.PageTemplates.ZopePageTemplate, line 295, in PUT TypeError: pt_edit() takes at least 3 arguments (2 given) Editing DTML methods, scripts, and SQL methods works fine. I've tried this in both 10.0 and 10.1. Anyone else having similar issues? Thanks, Eron

Correct location for robots.txt in virtual-hosted zope sites?
by John Schinnerer 09 Dec '06

09 Dec '06

Aloha, I have not been able to google up an answer to this, not for zope sites v-hosted behind apache anyhow. Do robots correctly find a file object named 'robots.txt' (containing text specifying the desired robot rules) if it is put in the root folder for a zope site v-hosted behind apache? For example apache points all requests for http://siteone.com/ to a folder named siteone.com in my zope 2.8.8 instance. If I put a robots.txt file in the siteone.com folder in zope, do the robots find it, as they would if it were a simple static HTML site? If not...how is this handled for zope sites v-hosted behind apache? thanks, John S. -- John Schinnerer - MA, Whole Systems Design ------------------------------------------ - Eco-Living - Whole Systems Design Services People - Place - Learning - Integration john(a)eco-living.net http://eco-living.net

Return code for Authentication error
by Sébastien VINOT 09 Dec '06

09 Dec '06

Hello, I try some tests with my zope (2.9.4-final on Debian) and Python about accessing private pages. I'm using the examples on page http://www.voidspace.org.uk/python/articles/authentication.shtml with the HTTPBasicAuthentication. Unfortunately that does not work. I set the View Permission to "Member" to one page. Of course I cannot access it if I'm not authenticated. I use the code below (extracted from the URL I gave above) but I only receive the "Please login page". How can I do ? The code : import urllib2 theurl = 'www.someserver.com/toplevelurl/somepage.htm' protocol = 'http://' username = 'johnny' password = 'XXXXXX' # a great password passman = urllib2.HTTPPasswordMgrWithDefaultRealm() # this creates a password manager passman.add_password(None, theurl, username, password) # because we have put None at the start it will always # use this username/password combination for urls # for which `theurl` is a super-url authhandler = urllib2.HTTPBasicAuthHandler(passman) # create the AuthHandler opener = urllib2.build_opener(authhandler) urllib2.install_opener(opener) # All calls to urllib2.urlopen will now use our handler # Make sure not to include the protocol in with the URL, or # HTTPPasswordMgrWithDefaultRealm will be very confused. # You must (of course) use it when fetching the page though. pagehandle = urllib2.urlopen(protocol + theurl) # authentication is now handled automatically for us
