RE: [Zope] Exsternal method quote

[ Projekt01, Roger Ineichen] What can I do if I whould return html code frome a external > method? It always quote the return string > Mostly, you should not return html from an external method. Return a string, list, or dictionary and create the html from that using dtml or zpt. That is what they are good at. There can be one exception, and that is if you use the external method to run an stylesheet to transform some xml into html. I do that, and I have never needed anything else but dtml-var. Of course, I still use an older version of Zope, but I do not think that has changed. Cheers, Tom P

newbie question CMF/Plone
by Fabien Nkundabagenzi 23 Oct '02

23 Oct '02

Hi, Can anybody tell me how to edit a portal_type (like File) to be able to add new properties (metadata) (for example: "geofocus") to the file using CMF/Plone ? Simply adding additional metadata doesn't seem to work. I tried modifying the File.py and the DublinCore.py scripts to include additional entries, and the file_edit_form as well. But when a try to add a File type, it returns the message : Dating not found in 'request/geofocus | here/Geofocus' What else should I do ? Thanks, Fabien.

But I suspect this is just because you gave a simplified example. See, the problem with your idea is more or less exactliy the same a with the squid solution: you will not see changes on a page immediatly, as the cached method can't really know if the context has changed (in case of your local_root thingy, what happens if you have changed the id of a folder higher up? Actually, because Accelerated Cache Manage can purge pages on the proxy, I think the solution you can get with squid is exactly the same as with your proposed solution - just some magnitudes faster. cheers, oliver

DTML Calendar tag problem
by Vitor Varalonga 23 Oct '02

23 Oct '02

Hi! I've just installed version 1.0.13 of the DTML Calendar tag on my Zope server. I was trying to build an example page, using this tag, and I noticed the HTML returned is not correctly constructed (a closing table tag is missing or misplaced) and everything looks messed up. Is anyone aware of this bug? kind regards, Vitor Varalonga

iptables locks out zope ftp
by Roel Van den Bergh 23 Oct '02

23 Oct '02

been on to this for a while but haven't found the solution yet Searching the net I found similar cases but with no answer :-( using iptables we can ftp to the server and access zope ftp through port 8021 but when the ftp program tries to open another port the ftp session is timed-out/blocked. When we disable the firewall we can ftp right into zope And yes we use passive mode Running zope 2.5.1 build from source, pyhon 2.1.3 build from source rpm, redhat 7.3 on dell powerapp 120 What's wrong?

size of image in LocalFS
by AM 23 Oct '02

23 Oct '02

Hi, I have a set of images in a LocalFS. I provide links to those images on another page and when a user clicks on those links a small window pops up that displays the image. Is it possible in anyway to figure out the size of the image in advance so that I can size the pop up window to be the same??

Thanks again for your help I downloaded Python 2.2.2 from www.python.org as my machine did not have Python 2.2 And i followed the step by step procedure you had suggested . When I tried to start zope with the command python2.2.2 z3.py it gave me the following error: Traceback(most recent call last): File "z3.py" line 72 in ? run() File "z3.py" in run XMLConfig(os.path.join(dir,'site.zcml'))() File " /Software/Zope3/lib/python/Zope/Configuration/xmlconfig.py",line 221, in __ init__ self.directives) File "/Software/Zope3/lib/python/Zope/Configuration/xmlconfig.py",line 276 , in xmlconfig parser=make_parser() File " /Software/Python-2.2.2/lib/xml/sax/__init__.py",line 93, in make-parser rave SAXReaderNot Available("No parsers found",None) xml.sax._exceptions.SAXReaderNotAvailable No Parsers found Is it because while doing the mak operation in Python I made an erro I used the command >> make makefile=MakeFile Or is there something else I am missing out?
