You may be right, but I have found a lot of other posts on Internet that
they complain about "belongs_to". It does not bear the correct meaning for
all cases. For example:
class Product
belongs_to :status
end
.....Awful. No, the Product does not "belong" to a Status. It "has_a"
status.
Also, "belongs" usually means that a "composition" relationship, such that
if Status were to be removed, the corresponding Product would have to be
removed too.
Another example:
class Product
belongs_to :type
end
....Awful again. The product Types preexist the Products and a Product does
not belong to a type. "is of" a type.
Certainly, the "belongs_to" as a DSL does not describe the domain on the
particular cases.
Thanks for letting me know that my workaround will work. I will have the
second thoughts on whether to use or not. I have read the article by Dave.
Thanks for that reference too.
