New SQLAlchemy Add Record Error - sqlalchemy

Question

Newbie to SQLAlchemy.
I'm having trouble adding a record. I modeled the add after the tutorial which passes multiple values (albeit hard coded values.) Attached is the routine and the error.
StackOverflow thinks my 'explanation to code' ratio is off, so I'm adding additional explanation so I can submit my query.
import pdb
from table import wrl
from sqlalchemy import or_, and_, desc, asc
from sqlalchemy import create_engine
from sqlalchemy.orm import sessionmaker
rs = create_engine('credentials', echo=True)
aws = create_engine('credentials', echo=True)
rs_session = sessionmaker(bind=rs)
aws_session = sessionmaker(bind=aws)
rs = rs_session()
aws = aws_session()
# pdb.set_trace()
y = rs.query(wrl).order_by(wrl.UUID_PK).first()
cat = y.Added_Timestamp #now we have the oldest record time stamp value
query_string = cat[:8]+"%" #now we have the oldest record's date i.e. substring(20111215_121212;1;8)
move_me = rs.query(wrl).filter(wrl.Added_Timestamp.like(query_string)).limit(10)
pdb.set_trace()
for x in move_me:
# pdb.set_trace()
wrl_rec = wrl(x.UUID_PK,
x.Web_Request_Headers,
x.Web_Request_Body,
x.Current_Machine,
x.Current_Machine,
x.ResponseBody,
x.Full_Log_Message,
x.Remote_Address,
x.basic_auth_username,
x.Request_Method,
x.Request_URI,
x.Request_Protocol,
x.Time_To_Process_Request,
x.User_ID,
x.Error,
x.Added_Timestamp,
x.Processing_Time_Milliseconds,
x.mysql_timestamp)
aws.add(wrl_rec)
aws.commit()
print 'added %s ' % x.UUID_PK
Traceback (most recent call last):
File "migrate.py", line 47, in <module>
x.mysql_timestamp)
TypeError: __init__() takes exactly 1 argument (19 given)
Any suggestions appreciated.

Answer 1

The problem is not really SA related. My conjecture is that your constructor (wrl.__init__(self, ...)) is either not defined, or does not take any positional arguments, which you are trying to specify when creating this object in wrl_rec.
So basically, the error message is pretty much indicating your problem.
On a side-note, does order_by(wrl.UUID_PK) really return the oldest record by the Timestamp as your comment few lines below indicate? Somehow I highly doubt that.
