This might be a painfully bad idea, but it's gotten me curious. I have a generic object Node, which has a name attribute. Say for example that one of the names is "Widget".
What I'm wondering is, is there a way to manipulate ActiveRecord to make a class named Widget, that behaves exactly like a Node with the only difference being that all operations only work on the condition (name="Widget") is true? I can do a simple class Widget < Node to get it started, but I'm looking for what the next line would be, where I can specify the global condition. In all other cases,
History : The database itself is generated rather, well, generically by scanning a file where I don't know the nature of the content beyond simple node relationships (i.e. I don't know ahead of time all values for "name"). However, I'm thinking that after the flat data storage portion is taken care of I could go in and maybe write some sort of generator for myself that would build up the Ruby classes to deal with the database, and hide the whole thing.
