In the olden days we had a saying "It can be anything". This still holds true. I Just uploaded and downloaded a file via ftp.: 14,175,113 bytes transferred in 00:00:02, 7,087,556 bytes/sec That is on a 1 GHz machine with 512 MB ram. So basically Zope is fast enough. Others have confirmed this. So I think you need to describe your setup very accurately. It could even be a hardware problem. Perhaps a network problem. Or more likely a software configuration problem. When you download big files via. http, is that also only 10 KB/S? When you are running an ftp client on the server directly to zopes ftp port (8082 or whatever) is it still as slow? Do you proxy the ftp to port 21 through some software? Any special router hardware/softare in front of the Zope server doing nat'ing? etc. etc. regards Max M

handling SELECT 'onchange'
by Jim Anderson 01 Mar '04

01 Mar '04

I have source code that someone original wrote in javascript and which I'm attempting to get running in Zope by replacing the javascript code with DTML and an external python method but my code does not work. The HTML/DTML code looks like this: <SELECT name="myselect" onchange=<dtml-var expr="select_handler(value)"> > <OPTION value="choice1">choice1</OPTION> <OPTION value="choice2">choice2</OPTION> <OPTION value="choice3">choice3</OPTION> </SELECT> Question 1: Should this work? Question 2: Does it make sence to change the client side javascript code with server side DTML? It seems like it may be better to let the javascript code deal with the selection for efficiency. Jim

ERROR(200) SiteError http://localhost/manage_workspace
by Josef Meile 01 Mar '04

Hi, every time that I hit something on the ZMI (In Zope 2.7.0), I got this error on my event log: 2004-02-27T18:15:55 ERROR(200) SiteError http://129.132.39.139/manage_workspace Traceback (most recent call last): File "/usr/local/Zope/2.7.0/lib/python/ZPublisher/Publish.py", line 100, in publish request, bind=1) File "/usr/local/Zope/2.7.0/lib/python/ZPublisher/mapply.py", line 88, in mapply if debug is not None: return debug(object,args,context) File "/usr/local/Zope/2.7.0/lib/python/ZPublisher/Publish.py", line 40, in call_object result=apply(object,args) # Type s<cr> to step into published object.

True As expected it printed "True", so, I concluded that this error will be always there because m.find('/') is always true, so I think it would be most correct to do: if m.find('/')==-1: ----raise Redirect, ( --------"%s/%s" % (REQUEST['URL1'], m)) Regards, Josef

Can I store structured text in a relational DB?
by nwingfield＠dixon-hughes.com 01 Mar '04

01 Mar '04

I am maintaining a content management site that uses a very user-unfriendly rich text / html editor that allows users to format their content. The generated html is saved off in PostgreSQL and retrieved when the corresponding page is requested. The client is quite frustrated with this editor because it causes them so much grief. Is it possible to save structured text to the database instead, and translate it upon retrieval from the DB? I (and the client as well) think this would be a wonderful solution, but I don't know if it can done.

Adding instances of objects using manage_addProduct()
by post＠volker-hemmelrath.de 01 Mar '04

01 Mar '04

Hi, I am quite new to ZOPE. I am trying to dynamically add new objects into Zope from an External Method. (zope 2.6.3) Adding folders using for example: self.manage_addProduct['OFSP'].manage_addFolder('vhe2','kltest2') That works fine. But now I want to add dynamically a Product called 'ExtFile/ExtImage' (perhaps you know it). I downloaded and installed it. It works find within ZMI. I tried the following in the external method: self.manage_addProduct['ExtFile'].manage_addExtImage('xxx', 'XXXX', 'test xxx', '/home/volkerh/zope/IMGP0377.JPG', '', 'image/jpeg',0,'','', 0,0,None) That does not work. Obviously it does not find the product and the manage_addExtImage-method. Bevor I try to go on with it. Is the second example ok at all or what mistake. Does it has to be self.manage_addProduct['ExtFile'] or something else. Does anybody can show me a working template ? Thanks for any hint. Volker

Win32 Zope Instance
by Gál László 01 Mar '04

01 Mar '04

Hi! I've installed zope 2.7.0 to my windows, choosing to split instance and software home. Next I've installed all my products and python modules I needed, and put it together in one directory, rewriting the paths in all files (etc/zope.conf, bin/runzope). I also made a custom_zodb.py. (actually I want it to burn to cd-rom then) Finally I uninstalled the original zope, cleared all zope-related stuffs but this directory, and it works! It works even I rename that directory. BUT: If I copy it to another machine (where zope was never installed), I've got the following traceback: E:\>"\zope\bin\python.exe" "\zope\lib\python\Zope\Startup\run.py" -C "\instance\ etc\zope.conf" E:\zope\bin\lib\fcntl.py:7: DeprecationWarning: the FCNTL module is deprecated; please use fcntl DeprecationWarning) Traceback (most recent call last): File "\zope\lib\python\Zope\Startup\run.py", line 49, in ? run() File "\zope\lib\python\Zope\Startup\run.py", line 18, in run opts = _setconfig() File "\zope\lib\python\Zope\Startup\run.py", line 41, in _setconfig opts.realize(doc="Sorry, no option docs yet.")

Yes, I could read a text file using External Method. Thank you. Elena. > elena(a)hpcf.upr.edu wrote: > >>I'm new to Zope.
