It has nothing to do with "looking cool" or anything like that. Using models.fields as class attributes in models class statement's body allow for the ORM to know what db fields and relations your table has - not what instance attributes a model instance will have. Well, not directly at least - of course the Model base case makes sure your instance will have corresponding instance attributes (for db fields), but note that these instance attributes are just plain python attributes, NOT the models.fields you defined at the class level. > And then behind the scenes they just hide that name variable somewhere and > create another name object-variable.

Python classes are objects too. And FWIW, s/ properties/attributes/, in Python 'property' is a builtin type used for simple computed attributes. Also and FWIW, Django is a Python framework, so "users" are supposed to be Python programmers. > That's one of things why python is broken, imho. Saying so just show your lack of understanding of Python's very powerful object model. It might not fit your brain, but that doesn't make it "broken" in any way. -- You received this message because you are subscribed to the Google Groups "Django users" group.
