Hello, I try to cache.ram a lambda represent function like Massimo suggest in this post :
http://www.mail-archive.com/[email protected]/msg52736.html My problem is that there record where the field to be represent is empty... I was using the and/or trick before like this that was working ok : db.table1.create_by.represent=\ lambda value: (value!=None and "%(initials)s" %db.auth_user[value]) or 'None' But now, I want to speed my app a bit with cache.ram... This work great as long as the field have been filled : represent=lambda id: cache.ram('%id' %id, lambda:db.auth_user(id).initials, 3600) I try many different things, like : represent=lambda id: cache.ram((id!=None and '%id' %id, lambda:db.auth_user(id).initials) or 'None', 3600) # NOT WORKING CAUSE : TypeError: 'int' object is not callable represent=lambda id: cache.ram('%id' %id, lambda:db.auth_user(id).initials if id!=None else 'None', 3600) # NOT WORKING CAUSE : TypeError: %d format: a number is required, not NoneType Also try with function... Any idea... Thanks Richard
