DB: class to multiple rows mapping (aka rails 'osproperty')
Hi,
Has anyone implemented some sort of automatic class to dynamic table
mapping ?
The idea is to have a single table capable of storing various unrelated
classes. Some sort of Extreme polymorphism.
I''ve used this with other languages. E.g. osproperty in Java. The idea
is the following
In the DB
create table dynamicobjects (
id int,
object_type varchar(255),
key_name varchar(255),
value_type int,
value_int int,
value_char varchar(255),
value_longchar text,
...
primary key (id, object_type, key_name)
)
then I could map any in...
