I attempted to send the following directly to the author of the subject How-To, but the mail bounced, so I thought I might post it here, just in case he might see it... I just wanted to thank you for posting your How-To on accessing a ZSQL Method from an External Method. I had just gotten to the point in my project where I needed to do just that, and was scratching my head wondering how to do it. I finally decided to take a look through the Zope site How-To's and ran across yours. It was exactly the information I was looking for, and very clearly written. Thank you very much! I'm sure it has saved me hours and hours of frustration poring through the Zope docs trying to figure it out. I'm still fairly new to Python, but the only part of your How-To that, IMHO, might be written a little more simply is the code fragment in the "What is res?" section: fields2index={} fieldnames=res._schema.items() for i in range(len(fieldnames)): fields2index[fieldnames[i][0]]=fieldnames[i][1] which might read more clearly as: fields2index = {} for name, index in res._schema.items(): fields2index[ name ] = index Just a suggestion. In any case, thanks again for posting your "lifesaver" How-To... Regards, Dave Morrill
