I was also trying to accomplish this a while back. I managed to add the new class with a database connection and execute sql statements. My class had some stuff like this: def __init__(self,id,title,dbconn): self.id=id self.title=title self.dbconn=dbconn self.times={} def getProducts(self): stmt = 'select prdt_id as id, product as name from products' dummy, components = self.exec_sql(stmt) return components def exec_sql(self, stmt): "Execute a piece of SQL code -- Need to convert to some sort of ZSQL Method" db = getattr(self, self.dbconn) col_names, raw_results = db().query(stmt) col_names = map(lambda x: x['name'],col_names) return col_names, raw_results Now it worked... but here's my problem/question... These methods, while executing SQL, are not ZSQL Methods, which means I'm not getting any of the good caching and other bollocks. I was categorically unsuccessful adding ZSQL Methods to the class. Does anyone have any tips to how I could turn exec_sql into a ZSQL Method? Monty Ivan Raikov wrote:

Greetings,

For the past few days, I've been unsuccessfully trying to use a Zope ODBC connection from within a Python class.

I have the following situation:

1. A Python class, Order, which has this method:

def create (self, cust_id, connection_id = None, itemcode = None, quantity = 0):

while self is not None: if hasattr(self, 'objectValues'): for o in self.objectValues(): if hasattr(o, 'id'): if o.id == connection_id: self.connection = o

self.cust_id = cust_id self.itemcode = itemcode self.quantity = quantity query = 'insert into orders (cust_id, itemcode, quantity) values (%s, \'%s\', %s)' % (self.cust_id, self.itemcode, self.quantity)

if self.connection != None: self.connection._begin() result = self.connection.query (query) print result self.connection._finish()

2. A Zope class, TestOrder, which subclasses Order. Its constructor tries to invokes 'create', however upon executing the SQL query, Zope either dies and is restarted, or just sits there, doing nothing, until the HTTP connection times out. In either case, the new record is not written in the database.

3. Zope 2.1.7 Z ODBC DA 3.0.3 Solid dev kit 2.3 RedHat Linux 6.1 on i386

Please help.

Thanks, Ivan Raikov
