Q:

Multiple databases in Pyramid

Firstly, I'm new to Python.
Now that that's out of the way. I'm trying to access data on 2 different databases and display information on one view.
http://docs.pylonsproject.org/projects/pyramid_cookbook/en/latest/pylons/models.html#multiple-databases
This^ seems incomplete after the first paragraph. I have the first database working and complete, and it works great. Now I'm trying to incorporate a second database.
I can't find anywhere what my development.ini file should look like if I have a second database. I have this:
sqlalchemy.url = mssql+pyodbc://[databasestuffsredacted]

and I figured something like
db2 = mssql+pyodbc://[seconddbstuffsredacted]

(both databases use the same type and driver) From a previous stack overflow question, this was mentioned:
DBSession2 = orm.scoped_session(orm.sessionmaker(extension=ZTE())

But, how in the world does that talk to my second database. I'm missing a crucial piece here that I think should have been in the document above after the first paragraph. 

A:

you can write it in a module
engine= create_engine('postgresql://user:pswd@localhost/db1')
DBSession = scoped_session(sessionmaker(extension=ZopeTransactionExtension()))
DBSession.configure(bind=engine)

engine2= create_engine('postgresql://user:pswd@localhost/db2')
DBSession2 = scoped_session(sessionmaker(extension=ZopeTransactionExtension()))
DBSession2.configure(bind=engine2)
