I've been told it's better practice to observe the ModelAddedNotification, instead of setting it up in a constructor. I guess the reason is that in case EOF needs to load the model again at some later time for some reason it will work. I switched our stuff to the notification way (was originally in constructor) and have no complaints.

We do this in our base application class constructor:


                NSMutableDictionary overrides = new NSMutableDictionary();
                EOModel model = 
EOModelGroup.defaultGroup().modelNamed("MyModel");
                overrides.takeValueForKey(dbURL, "URL");
                if (dbUser != null && dbPassword != null) {
                        overrides.takeValueForKey(dbUser, "username");
                        overrides.takeValueForKey(dbPassword, "password");
                }
EODatabaseContext dbContext = EODatabaseContext.forceConnectionWithModel(model, overrides, new EOEditingContext());

We have 4 different environments that we deploy to, development, test, staging, and production. We are using ant as our build tool.

For most of our environments we connect to a localhost database with a common password, but production is on an external server which has a more secure password. What is the best way to change the db connection at build time?

Example:
When I build for production, I want to make sure the connection is pointing to the correct server and the password is correct.

I know I can use ant to search and replace for connection string tokens in the Properties file, but is this the easiest way?
