Well, no problem:
I use a MySQL database connection through a Z Mysql Database Connection,
and I use this from my own product.
The code to access the database is partially stolen from Z SQL Method and
looks like this:
self.connection = connection
self.dbc = getattr(self, self.connection)
To submit queries I do the following:
DB = self.dbc()
result = DB.query("select wuh from wobba")
"connection" is a reference to a Z MySQL Database Connection (I think), which I got
the following way (stolen from ... ):
while self is not None:
if hasattr(self, 'objectValues'):
for o in self.objectValues():
if (hasattr(o,'_isAnSQLConnection') and o._isAnSQLConnection
if type(id) is not StringType: id=id()
if not have_id(id):
if hasattr(o,'title_and_id'): o=o.title_and_id()
if hasattr(self, 'aq_parent'): self=self.aq_parent
ids=map(lambda item: (item, item), ids.items())
Well, this is the way I do it right now.
I'm sorry if I give you a total overkill, but I truly have no clue how
this mechanism relly works, and I found absolutely no documentation from
the Zope site (which is a major flaw in Zope I think ...).
If you can comment something useful to this mess I would be quite happy,
otherwise ... well, it works ;-))
Bye, thanks and greetings,
