Hi!
I got this class arrangement:
class Document(Base):
doc_number = Column(:)
doc_date = Column(:)
:
class Invoice(Document)
class CashOrder(Document)
class BankTransaction(Document)
It's joined table inheritance, Document has a table with discriminator etc.
So, I need to iterate through Documents and at each iteration I have to get
"real" object (i.e., Invoice instance). Right now all I got is a collection
of Document objects that contain only doc_number & doc_date fields, nothing
else. I've though that a discriminator field can somehow be of help - if
only I could establish a non-ambiguous link between string it contains and a
class. Any thoughts? Thanks!
