simple use case for rotating images
by David Bear 16 Apr '08

16 Apr '08

We are finding that flash is used to generate simple slide shows. I'm thinking it would be 'better' to use an ajax like method and zope to serve up a set of standard images. Anyone know of examples? I completely new to ajax and have looked at a few ajax libraries. So far they all see overkill for what I want. -- David Bear College of Public Programs at ASU 602-464-0424

Problem with DTML and JOINS(ZSQL)

Dear all, I am developing a web application for a biological research institute down here in india. I have some problem in using JOINS. The below is the queries i used, *SQL query **File name : drug* select drug_name,dtype from bio_info_schema.drug order by dtype *File name:drug_gene_details* Note : i used both the sql queries seperately, but neither one worked.

try clause in external method
by Garry Saddington 15 Apr '08

15 Apr '08

I have the following external method which takes an input .csv file and enters the data into a database by calling a ZSQL method. There may be errors in the input file and so I am trying to catch them and insert each bad row in a different table. The errors are detected by table constraints on the table definition and should be reported by the Psycopg connector. However no correct rows are entered and only the last error row is entered. Can anyone see what I am doing wrong in this script? def timetabler(self,REQUEST): import csv,string f=REQUEST.form["TTEXPORT.CSV"] from cStringIO import StringIO filebody=StringIO(f.read()) r = csv.DictReader(filebody("day","periodstart","periodend" ,"year","teachgroup","teacher" ,"subject" ,"set" ,"room")) for row in r: try: self.insertintoiclasses(**row) except: self.insertimporterrors(**row) dtmlMethodName="manage_import_from_timetabler" return self[dtmlMethodName](self,self.REQUEST) regards garry

Upgrade to 2.7.2 results in all content unavailable
by Wes Modes 14 Apr '08

14 Apr '08

I upgraded to Zope 2.7.2 and all of my content can't be seen by Zope. Honestly I'm not sure what the previous version I was running was (nor am I sure how to find out). Now, every page results in Site Error An error was encountered while publishing this resource. Resource not found Sorry, the requested resource does not exist. Check the URL and try again. Resource: Zope GET There is effectively no more web interface. I've verified that the database still seems to be there in [instance]/var/Data.fs and hasn't been touched since the update. I tried going through some of the steps in the Troubleshooting and Debugging page http://www.zope.org/Documentation/Books/ZDG/current/TestingAndDebugging.stx I can do a ZPublisher.Zope('/manage') in python and see that it returns a "Resource not found" page. Interestingly, my log which was being written to /var/log/zope started writing to the default location after the install. I feel like there isn't enough here to determine whether there is a bug or whether I've mucked something up myself. But perhaps some gentle guidance would help me determine whether there is a bug or just my own ignorance. Was there a config file that got overwritten in the update? Where would it be? Perhaps there are some clues in the lines written to the log file upon startup.

File objects AttributeError:alt
by Palermo, Tom 14 Apr '08

14 Apr '08

I've recently upgraded my Zope version from 2.7.6 to 2.9.8. I've recently discovered that older File objects are generating an AttributeError: alt whenever I call manage_changeProperties() on those File object instances. I'm aware of the change to lib/python/OFS/Image.py that removed the alt class attr from the File class. I thought my File objects would have automatically updated too but, apparently not. I just tried doing the following: objs = context.ZopeFind(context.this(), obj_metatypes=['File'], search_sub=1) for k,v in objs: if hasattr('alt',v): delattr('alt',v) The above code didn't seem to do anything to fix the issue. Any suggestions would be greatly appreciated. Sincerely, Tom Palermo
