I have a declarative model as below
class User(Base):
__tablename__ = 'users'
__table_args__ = {
'schema':'internal',
'extend_existing': True,
'mustexist': True
}
The table has a column named 'registration_date'. Since I am working with
pandas I'd like to wrap this in a pandas timestamp when using it.
Ideally something like this would be possible:
def registration_date(self):
return pd.to_datetime(self.registration_date)
But this causes a name collision between the mapped column and this new
method so trying to query the column via User.registration_date will not
work as this returns the method instead of the queryable attribute. The
natural solution would be to rename the method but that isn't ideal as I
want all my users to have the same idea of a registration date. Is this
possible in sqlalchemy?
