Hi, I want to use a discriminator based upon a column of a related table. I found the relevant place in the docs http://docs.sqlalchemy.org/en/latest/orm/inheritance.html#joined-table-inheritance
"The discriminator column is only needed if polymorphic loading is desired, as is usually the case. It is not strictly necessary that it be present directly on the base mapped table, and can instead be defined on a derived select statement that’s used when the class is queried; however, this is a much more sophisticated configuration scenario" However this is not working for me, additionally I found this stackoverflow question which also encounters this problem to a tee. http://stackoverflow.com/questions/40862634/sqlalchemy-orm-polymorphic-on-from-relationship What is the correct method to have a discriminator based on a more complex select statement?
