RE: [Zope] How do I get product to return other than ZMI page?
by Bill Hewitt 29 Mar '04

29 Mar '04

I dont know if this is kosher, but I generally just add the following to my "add" method (Straight from Zope Product defaults) request.RESPONSE.redirect(instance.aq_parent.absolute_url() + '/?caller=Manager') ################################################################## [Notice that the above line calls index_html from the context of the parent directory with a content argument - the '/?caller=Manager' part. The argument part(2nd line) is where you would put the name of the file you want to return - it inserts your doc in the correct context for what you want to do(?).....] Probably a slicker way to do it, but this always works for me...] ################################################################## Good Luck WPH

executing external methods over nfs
by Lester Cram 29 Mar '04

29 Mar '04

I have written an external method that changes information in a file a bit like the write to file method. It uses import os and system calls for shell commands(the shell commands owner and group is abc) the script uses os.chmod 0777 on the file, alters it with the shell command and then os.chmod 644 It works when the file is anywhere on the local filesystem but not over nfs. Zope is started by root and the exernal method is owned by root. themethod.py is owned by root nfs is mounted as in fstab 10.10.10.10:/SHARE1 /nfs1 nfs addr=10.10.10..10,noauto 0 0 /nfs1 has root ownership and everything below this is 65534 (nobody) user and group with the relevant files read write lor the user and read for group and others there is no entry in etc/exports another shell based command (owner abc group abc )writes the initial files to nfs I beleve that the problem relates to file permissions but dont know how to fix it.Any help appreciated.

Zope, Apache & mod_proxy
by John Poltorak 28 Mar '04

28 Mar '04

Can someone remind me about how Apache needs to be set up to allow Zope to work with it? I did have it working, but found that the use of mod_proxy allowed Apache to be used as an open mail relay. Is this a known problem? -- John

Zope 2.7 FTP Bandwidth Limiter?
by Edward Pollard 28 Mar '04

28 Mar '04

We're experimenting with Zope 2.7, and are currently unable to get FTP transfers to go any faster that 10k/sec. This seems to be some sort of arbitrary limit, as we have plenty of bandwidth and horsepower available. Indeed, we can pretty much make as many FTP sessions as we want simultaneously, they just all go at 10k/sec. Was there some sort of limiter or throttle introduced somewhere along the lines that I am unaware of? --- Edward J. Pollard, B.Sc Webmaster, University of Lethbridge

zope string question, easy for pythonistas
by Joshua Newman 28 Mar '04

28 Mar '04

Hi all, I'm trying to compare an AUTHENTICATED_USER string to a variable which I named '2nd_smr' in this script to determine if it should be bolded in a big table and stick out for the user: <dtml-if "_.string.lower(_.str( AUTHENTICATED_USER)) in _.string.lower(_.str(2nd_smr))"> <b>2ndS <dtml-var 2nd_smr ><br></b><dtml-else> 2ndS <dtml-var 2nd_smr ><br></dtml-if> The above script won't save, and gives an error. The _.string.lower(_.str(2nd_smr)) expression is obviously the culprit and won't save unless I do ('2nd_smr') which saves but isn't what I want obviously, and ("2nd_smr") won't save. Did I screw up by naming a variable with a number as the first character? Is is salvageable with some funky syntax like: _.string.lower(_.str(_['{2nd_smr}'])) or do I have to just change the name of the variable? Thanks J

Pythonscript question
by drew nichols 27 Mar '04

27 Mar '04

Can i get methods dynamically from a pythonscript? getattr doesn't seem to work. I guess external methods would work, but can this be done? ##parameters=method=None ## def a(): return 'Hello' if method is not None: return getattr ( script, method )()

Thread in Zope 2.6.2
by Florian Reiser 27 Mar '04

27 Mar '04

Hello, I've tried to create a thread under Zope as it is described in Case 2 of http://www.zopelabs.com/cookbook/1058719806 . The code runs fine until the thread tries to commit the txn with try: get_transaction().commit() connection.close() except: pass In the call connection.close() I get the error ERROR(200) ZODB A storage error occured during object abort. This shouldn't happen. Traceback (innermost last): File C:\PROGRA~1\Zope-2~1.2\lib\python\ZODB\Transaction.py, line 401, in _commit_error File C:\PROGRA~1\Zope-2~1.2\lib\python\ZODB\Connection.py, line 658, in tpc_abort AttributeError: 'None' object has no attribute 'tpc_abort' What have I done wrong? With kind regards Florian Reiser
