Re: sqlalchemy on IBM i.

Kevin Adler responded on Ryver (where I cross posted) and had me:

"pip3 install future"

That fixed the issue. Apparently there was an update to ibm_db_sa where
the
future module is needed, however the install.py script had not be updated
to
include it.

Hi Jim

sure looks to me like it's the import; it seems interesting to me that it
can't find module "future" rather than "future.utils" - almost like the
name
resolution is a problem.

I see you have "from ." in your other import statements so it seems there
is
some relationship to path in the import statements that I have not struck
in
my python scripts yet (all on windows)

I'm trying to get an sqlalchemy test to work and it stops with the
following:

bash-4.4$ python3.6 alchemy_test.py
Traceback (most recent call last):

line 26, in <module>
from future.utils import iteritems
ModuleNotFoundError: No module named 'future'

If I am readying this right, the module "future.utils" is part of the
sqalchemy package. The code calling it is:

import sqlalchemy
from sqlalchemy import *
import ibm_db_sa.ibm_db_sa
db2 =
sqlalchemy.create_engine('ibm_db_sa://python:pythonusr@xxxxxxxxxxxxxxx
:50000
/python')
metadata = MetaData()
users = Table('users', metadata,
Column('user_id', Integer, primary_key = True), Column('user_name',
String(16), nullable = False), Column('email_address', String(60),
key='email'), Column('password', String(20), nullable = False)
)
metadata.bind = db2
metadata.create_all()
users_table = Table('users', metadata, autoload=True,
autoload_with=db2) users_table

I think it's the import* that's causing the issue.

This is just a see if it can connect script and I lifted it from the
IBM page on sqlalchemy (which of course has no reference to IBM i)
