I've read about examples on inheritance with rails.
Here is an example:
The way is to add a type field in the table.
So if I have an Animal class with an attribute name, I can inherit
from this class like:
Dog < Animal, Cat < Animal, and so on.
With the type field in the table I can do Dog.all, Cat.all having
automaticaly all dogs, all cats, etc.
But what if I want to add some other attributes to Dog or Cat classes?
In the example above all classes have only name attribute.
What if I want inherit from Animal extending attributes and adding,
for example, an attribute like canFly? for inherited classes?
