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

But there is usually no need for such an >approach. Somehow you're trying to do something the wrong way round. What I'm trying to do is change the line in question to this: stuff = stuff + '<span metal:use-macro="here/en-us/Quotes/' + `randrange(1, len(self.objectValues()), 1)` + '/macros/quote" ></span><br />\n' So it generates a random number. Now, that's the "easy" scenario, and for that I originally had just a Page Template. However, next up I need to be able to accommodate another folder which requires: 1) walking the folder, opening each subfolder 2) creating a tuple of the folder (or numerical representation) plus the number of the quote 3) randomly choosing a quote from all the subfolders Ideas? Perhaps I should instantiate a page template in the ext. method. How would I do that? TIA, Javier ____________________________________________________________________________________ Do you Yahoo!?

Why doesnt' this work?

Hello; I have this code that works fine in a Page Template: <html> <body> <table width="100%" align="center" class="text" border="3" cellspacing="5" bgcolor="#E694FE" bordercolor="#D24BFA" bordercolorlight="#DD77FB" bordercolordark="#C512FA"><tr><td> <span metal:use-macro="here/en-us/Quotes/10/macros/quote"></span><br /> <div align="center"><span class="text"> <a href="All_Quotes.pt" target="_top"><b>Show me all the quotes!</b></a> </span></div> </td></tr></table> </body> <html> But when I try to make it work in an External Method like this: stuff = '<html>\n' stuff = stuff + '<body>\n' stuff = stuff + '<table width="100%" align="center" class="text" border="3" cellspacing="5" bgcolor="#E694FE" bordercolor="#D24BFA" bordercolorlight="#DD77FB" bordercolordark="#C512FA"><tr><td>\n' stuff = stuff + '<span metal:use-macro="here/en-us/Quotes/10/macros/quote"></span><br />\n' stuff = stuff + '<div align="center"><span class="text">\n' stuff = stuff + ' <a href="All_Quotes.pt" target="_top"><b>Show me all the quotes!</b></a>\n' stuff = stuff + '</span></div>\n' stuff = stuff + '</td></tr></table>\n' stuff = stuff + '</body>\n' stuff = stuff + '<html>\n' it doesn't show the quote from this line: <span metal:use-macro="here/en-us/Quotes/10/macros/quote"></span><br /> but it shows the rest of the table and the link at the end. Why is that? Have I lost the context along the way? How do I preseve the context going into an External Method?

7373----- Original Message ---- From: Maciej Wisniowski <maciej.wisniowski(a)coig.katowice.pl> All of that worked, but so much for being "simple". Upon re-analysis, what I need to do is call a Script (Python) from within a page template but still retain the container.REQUEST from the previous call. That is, page template X calls page template Y which calls Script (Python) Z and Z needs the container.REQUEST of X. Is that possible?
