What if I don't have access to session? I receive obj (mapped SQLA
class instance) as an argument to a method.
What I actually would like to do is add a method to the class that does
the raw query like so:
class MyClass(object):
def __init__(self, arg1, arg2):
self.arg1 = arg1
self.arg2 = arg2
@property
def fetchOutsideAtts(self):
con = getConnection(self) # How do I do this.
con.execute(select fields from table where id = ?)
...
return atts
Is it possible to do this?
