I'm looking for the code that builds the key used in the identity_map of

if intellisense is scanning source code to determine what elements an
object has, then I don't see any way for it to do this unless you
actually typed in a new definition of some kind that laid out all the
attributes you'd like intellisense to know about. IMO such tools are
not practical
Hi , but how would you write query with this, this is what I want
class Cwle(Base):
__tablename__ = 'CardiacWaitListEntry'
wleid = Column('WaitlistEntryID',NUMERIC(18), primary_key=True)
qr = session.query(Cwle.wleid) <--- when I type Cwle. it will bring
intellisense with all columns
from sqlalchemy.orm import aliased as _aliased
def aliased(entity):
return _aliased(entity, name=entity.__table_alias__)
?

Hi, is possible to have "default" alias for table
class Cwle(Base):
__tablename__ = 'CardiacWaitListEntry'
__table_alias__ = 'CWLE'
I know you can do this
Cwle = aliased(Cwle, name='CWLE')
but this screw up any editor intellisense. Output of sqalchemy query would
be more readable
