Hi,
Does somebody know why, I am getting an error on this function (inside a zope-product):
[sniped code below]
The error message is:
Error Type: TypeError Error Value: unsliceable object
It looks much more like a python error than a Zope error per se. Besides, without a traceback or at least a line number where the error ocurred, it is really hard do divine where the error could have happened. But let me give you some hints about your code below
def CreateProcessDirs(self,proposalid,runid): for i in self.objectValues(): id=i.id if callable( id ): id = id() RequestDir=os.path.join(dir,proposalid,runid,'process',id)
here, instead of the loop above, you could just have said for id in self.objectIds(): RequestDir=os.path.join(dir,proposalid,runid,'process',id) besides objectIds and objectValues, there is also objectItems, which you can use like: for id, object in self.objectValues(): ... do something with id and/or object ...
if os.path.exists(RequestDir): print 'pathname ( file or directory) exist',path else: os.system('mkdir -p '+RequestDir)
here you could use python's own makedirs, to obtain the 'mkdir -p' effect, like: os.makedirs(RequestDir) that would also make your code more portable, as Windows mkdir doesn't like -p much...
print "Make Directory: ",RequestDir return i
None of those tips should solve your problem, however. In any case, try to look at the html source of the page that had the error to give-us a traceback so that we can help you better. Regards, leo
