Hi devs, thanks for replies!
Michael: I asked probably wrong question. I know how to make property read-only in Python, but I wanted the property to be read-only at ORM level (so it will not appear in UPDATE). Mark: This is probably is solution to my problem. I'm trying to create an abstract wrapper for ordered-list records. I wanted to post example which describes what I'm doing, but I will create another topic when basic features will be working.
