I am trying to write a convenience wrapper something like:
def wrapper(self, arg_a=None, arg_a=None):
query = self.session.query(Table_A).\
filter(Table_A.col_a == arg_a, Table_A.col_b == arg_b).\
all()
...
The actual query is much longer, none the less to handle the case where
the optional input is left out, the query needs different logic. Without
eval
and string formatting, how does one safely accomplish this?
Thanks,
jlc
