I have a PostgreSQL function discounted_price(packages%ROWTYPE), where
packages is a table. I would like to add a property on the model
corresponding
to the packages table which returns the result of the discounted_price
function.
Currently I have this which works:
@property
def
Hmm, I've tried that and gotten the following error:
ProgrammingError: (ProgrammingError) function discounted_price(unknown) is
not unique
LINE 1: SELECT discounted_price('packages.*') AS discounted_price_1
^
HINT: Could not choose a best candidate function. You might need to
(‘packages.*’)) won’t quote like that:
from sqlalchemy import func, text
print func.discounted_price(text('packages.*'))
discounted_price(packages.*)
