Potential PythonScript bug (was: Re: [Zope] question about manipulating zcatalog query results)

Re: [Zope] question about manipulating zcatalog query results
Dieter, I actually put the list in because one of the last suggestions in the archives to repair the problem had to do with enclosing the assignment in a list. The original code was essentially: if sorton == 'id': res=[(row.id.split().pop(), row) for row in results] res.sort() return res This doesn't work, either, in zope 2.7.4 or 2.7.5 with python 2.3.4 and 2.3.5 respectively, as far as I can see.

Re: [Zope] question about manipulating zcatalog query results
Chris, the relevant section of the script looks like this: zcat=context.Catalog if spontype == 'none': results = zcat(meta_type=mtype) else: results = zcat(meta_type=mtype,SB_sponsor_type=spontype) if sorton == 'id': res = [] rest = [] res = list(results) for row in res: rest.append(row.id.split().pop(), row) rest.sort() return rest this keeps garnering the 'global name _getiter_ is not defined under 2.7.5'...as you can see, the results have been transfered to a new list, so I'm not even looping and splitting the original query results (this was originally a much briefer script, but I've broken it down to see where exactly things were hanging up). If I pull the loop, or use a while loop and simply asign values from res to rest, then everything works fine, but as soon as I use that for loop, I get the _getiter_ error, and using split with the while loop (looks like: j = 0 while j len(res): k = res[j] kk = k.split().pop() rest.append(kk) j = j+1 ) I get AttributeError: split, or in the case of trying to play with the k string pulled from the list (by adding additional text, for example) I get Record objects do not support concatenation. I just can't see a way to play with the zcat query results without raising an error, and I'm dreadful confused... thanks again for looking into this ira On Apr 1, 2005 12:24 AM, Chris Withers [EMAIL PROTECTED] wrote: Ira Sher wrote: There is no call to _getiter_, of course, in the script, but whenever I use any for looping on the results, I get a variation of the above.

Re: [Zope] question about manipulating zcatalog query results
Chris,
a traceback for a script (testy in this case, called from
testyer_html, as I've broken out the problem area and have been trying
to work around it) using a for loop on a zcatalog result looks like:
* Module ZPublisher.Publish, line 101, in publish
* Module ZPublisher.mapply, line 88, in mapply
* Module ZPublisher.Publish, line 39, in call_object
* Module OFS.DTMLMethod, line 144, in __call__
DTMLMethod instance at 2b98350
URL: http://www.sarabandebooks.test/testyer_html/manage_main
Physical Path:/sarabande/testyer_html
* Module DocumentTemplate.DT_String, line 474, in __call__
* Module DocumentTemplate.DT_In, line 626, in renderwob
* Module DocumentTemplate.DT_Util, line 198, in eval
__traceback_info__: testy
* Module string, line 1, in expression
* Module Shared.DC.Scripts.Bindings, line 306, in __call__
* Module Shared.DC.Scripts.Bindings, line 343, in _bindAndExec
* Module Products.PythonScripts.PythonScript, line 302, in _exec
__traceback_info__: ({'traverse_subpath': [], 'container':
Folder instance at 2b923e0, 'context': Folder instance at 2b923e0,
'script': PythonScript at /sarabande/testy}, ('Author', 'id',
'none'), {}, None)
* Module Script (Python), line 16, in testy
NameError: global name '_getiter_' is not defined
There is no call to _getiter_, of course, in the script, but whenever
I use any for looping on the results, I get a variation of the above.
Any thoughts on this?
thanks again,
ira
