Zope-2.1.0b2 fails on access to management screen
by Jim Cain 19 Nov '99

I am running Zope through Apache, and when I access /manage, I get the following error each time: Traceback (innermost last): File "/opt/Zope/z2.py", line 583, in ? asyncore.loop() File "/opt/Zope-2.1.0b2-src/ZServer/medusa/asyncore.py", line 107, in loop poll_fun (timeout) File "/opt/Zope-2.1.0b2-src/ZServer/medusa/asyncore.py", line 66, in poll x.handle_error() File "/opt/Zope-2.1.0b2-src/ZServer/medusa/asyncore.py", line 321, in handle_error self.close() File "/opt/Zope-2.1.0b2-src/ZServer/PCGIServer.py", line 261, in close p.more() # free up resources held by producer File "/opt/Zope-2.1.0b2-src/ZServer/Producers.py", line 108, in more getattr(self.logger, self.method)(self.bytes) File "/opt/Zope-2.1.0b2-src/ZServer/PCGIServer.py", line 229, in log_request time.gmtime(time.time()) TypeError: illegal argument type for built-in operation Zope dies after this. I have tried both the source and Intel binary versions and get the same error. Cheers, Jim

Hi all. Does anyone know how to bind Zope to port 80? I mean, is it possible to do it straight trough zope or do I have to do it some other way..?

Michael: I "ain't no expert" on Apache but since you're stuck I'll flail with you! Look carefully (and hopefully grok) the Rewrite rules. It sounds like the directory is being rewritten incorrectly. > I'm reposting because I got no responses to this, and we're stuck. > > I would greatly appreciate any light you can shed on whether > Zap should > work with its cgi-bin like standard apache does, and how to > troubleshoot > problems.

Iteration over Z SQL Method resultset using fieldnames from TinyTable ??? Cannot figure this...
by Petri Savolainen 19 Nov '99

19 Nov '99

Hello, I am wondering how do I get an iteration over all the SQL fields that a Z SQL Method returns- simultaneously picking up the field names from a Tinytable that same Z SQL Method uses to get the data in the first place? I've got a SQL Connection to Postgres all set up, a TinyTable containing fields I want to query, and a Z SQL method called "GetCompanies" containing: SELECT <dtml-in QueryFields> "<dtml-var fieldname>" <dtml-if sequence-end> <dtml-else>, </dtml-if> </dtml-in> FROM companies; In which, fieldname is the variable containing the fieldnames I want, in the TinyTable. Great this far- it returns a nice table. But- if I want to format this, by iterating over "GetCompanies" (in a separate DTML Method), and adding some formatting there, I know just a "hardwired" way, as in: <dtml-in GetCompanies> ...formatting stuff... <dtml-var myfieldname> ...more formatting... </dtml-in> Because I know "myfieldname" is a name of a database field I know exists, and thus ends up in the namespace of "GetCompanies", as an attribute (correct???) Now, the problem is, what if I want to iterate over the data in GetCompanies, but don't know any fieldnames, I just know I can get them from the same old Tinytable?????? Would much appreciate- embarrassingly, I've spent hours trying to figure this simple thing out... I guess I have to list all that exists in the namespace of GetCompanies Z SQL Method (all the attributes?), then filter out the standard stuff ---> what is left is a collection of field names it has data for??? But how?? Thanks! Petri

Does the report parse the URL to determine >the search parameters, or is there a hidden method that I don't know about. The items in the form get stuffed into the REQUEST structure automatically via the normal HTTP post/Zope process. Then you can pass the REQUEST structure into the searchResults() method and the ZCatalog searchResults() method will match up any attributes in REQUEST with the set of columns you chose to index on when you created the HouseCatalog, and where there is a match in name, it will use it. This -can- be dangerous if you use generic-sounding columns in your catalog, as it can pick up unintended search criteria using items that already exist in REQUEST. You're safe with 'price' and such. There is also some risk with empty fields, where field=(empty) means match all such items, not ignore the field. In your case you would change the line in your example below:  into something like:  if your search criteria is specified via attributes in the REQUEST structure, say using the REQUEST.set type of arrangement or if you prefer explicit specification of such, like:  or even:  This will search for a house in the specified price range -AND- if it resides in -ONE OF- the specified states. This form gives you more control albeit at the cost of more complex code. Note that within the in-loop, as a performance speedup by ZCatalog, you will have access to those catalog fields that you specified in your metadata schema when you created the catalog, *NOT* those fields you indexed on. You can also retrieve the item itself, via the HouseCatalog.getobject(data_record_id_) method, or just it's URL, via the HouseCatalog.getpath(data_record_id_) method. __________________________________________________ Jeff Rush <jrush(a)taupro.com> Tau Productions Inc.
