So i have to overwrite dApp.getConnectionByName.
Ok, tested that kinterbasdb gets the right thing.
But i have to test this outside of dabo to be able to tell if the
translation works as expected.
But thanks for the change as we now are able to give the backend all
params that we want to use.

Is this still state of the art? If yes, I think it would have to look
like this:
def getConnectionByName(self, connName):
"""Given the name of a connection, returns the actual
connection. Stores the connection so that multiple requests
for the same named connection will not open multiple
connections. If the name doesn't exist in self.dbConnectionDefs,
then an exception is raised.
"""
if not self.dbConnections.has_key(connName):
if self.dbConnectionDefs.has_key(connName):
ci = self.dbConnectionDefs[connName]
# This is changed:
self.dbConnections[connName] = dabo.db.dConnection(ci,
charset="utf8")
try:
ret = self.dbConnections[connName]
except KeyError:
raise dException.ConnectionNotFoundException, _("No
connection named
'%s' is defined") % connName
return ret
The base class method can't be called, because the changed line comes in
the middle. Right?
