Hi everyone,
I have a 'sqlalchemy.orm.query.Query' object from that how can i know
what model it uses
use column_descriptions:
http://docs.sqlalchemy.org/en/rel_1_1/orm/query.html?highlight=column_descriptions#sqlalchemy.orm.query.Query.column_descriptions
from sqlalchemy import create_engine
from sqlalchemy.ext.automap import automap_base
from sqlalchemy.orm import Session
from sqlalchemy import MetaData
engine = create_engine("sqlite:///chinook.db", echo = False)
metadata = MetaData()
model = 'employees'
metadata.reflect(engine, only=[model])
base = automap_base(metadata=metadata)
base.prepare()
map_model = base.classes[model]
session = Session(engine)
query = session.query(map_model.LastName,map_model.FirstName)
Here the model i am using is 'employees'. But how can achieve this by
using 'sqlalchemy.orm.query.Query' object in the program
(i.e. query = session.query(map_model.LastName,map_model.FirstName)).
