1.5.3.1 Full Code Listing

Here is a complete code listing so that you can experiment:

#!/usr/bin/env python

import sys; sys.path.append('../../../') # show python where the modules are

import web.database, web.database.object
connection = web.database.connect(
    adapter="snakesql", 
    database="database-object-multiple",
    autoCreate = 1,
)
cursor = connection.cursor() 

person = web.database.object.Table("Person")
person.addColumn(web.database.object.String(name="firstName"))
person.addColumn(web.database.object.String(name="surname"))
person.addMultiple(name="addresses", foreignTable="Address")

address = web.database.object.Table("Address")
address.addColumn(web.database.object.String(name="firstLine"))
address.addColumn(web.database.object.String(name="postcode"))
address.addSingle(name="person", foreignTable="Person")

database = web.database.object.Database()
database.addTable(person)
database.addTable(address)
database.init(cursor)

if not database.tablesExist():
    database.createTables()
    print "Created Table"
else:
    raise Exception('Tables not created')
john = database['Person'].insert(firstName='John', surname='Smith')
print john['surname']
print john['addresses']

database['Address'].insert(person=john, firstLine='12 Friendly Place', postcode='OX4 1AB')
database['Address'].insert(person=john, firstLine='3a Crazy Gardens', postcode='OX1 2ZX')

for address in john['addresses'].values():
    print address['firstLine']

connection.close() # Close the connection without saving changes

The output is:

Created Table
Smith
{}
12 Friendly Place
3a Crazy Gardens

You will need to delete the database file object-multiple.db each time you run the cose so that it can be recreated each time.
