A and B are in the table, C isn't
If you just want to grab this value, you just need a standard Ruby
method in your model definition:
columnA + "-" + columnB
If you want to be able to write to this attribute as well, then you'll
have to write a method along the lines of
columnA, columnB = new_value.split("-")
although obviously there is some ambiguity with "strings-like-this".
Hope that helps,
