This request is slightly off topic. I like the way attributes of Django models are defined. I'd like to use a similar approach for a pure Python, too. Unfortunately, I do not really understand the code that does all the magic in the django.db.models module. I don't think it is possible to use Django models without a database. Therefore, can anybody point me to some tutorial/documentation on how to do this kind of meta programming in Python?
I'd like to solve three problems at once. My naive approach to map a complex web of objects directly on Django model objects was unbelievable slow (with sqlite3) and painful to use because I had to be careful to add save() methods all over the place. Additionally, I need transactions to be able to revert partial modifications of single method calls. It is my current understanding that Django does not have this feature. As I don't need to access individual objects randomly, I could serialize my whole web of objects and store it into a single binary database field. I was able to create simple transaction management on objects with attributes, but I need of course not only monitor attribute modifications but also lists and dictionaries, that is mutable sequences. At the same time, I like how Django expresses relations between objects and automatically manages them. So I tried to come up with some custom relation class - and failed so far ;( -- Stefan Matthias Aust --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
