Hi
I have a few properties on an class specefied in declarative that are
mapped to a select, but I have only figured out how to map them
individually. I'd like to be able to specify the select only once, and
then pick what property maps to which field name, and make sure they
load simultaneously, by using deferred. Is this possible?
Here is my model:
class Product(Base):
__tablename__ = "products"
product_id = Column(Integer, primary_key = True)
name = Column("Name", String)
score = column_property(select(["score"],
product_id == literal_column("al_id"),
from_obj = ["product_data"]),
deferred = True)
n_pro_reviews = column_property(select(["pro_reviews_count"],
product_id == literal_column("al_id"),
from_obj = ["product_data"]),
deferred = True)
n_user_reviews = column_property(select(["pro_reviews_count"],
product_id ==
literal_column("product_id"),
from_obj = ["product_data"]),
deferred = True)
