I'm going to go down the SQL path.
The intermediate model doesn't change the DB schema in your case. A models.ManyToManyField already implicitly creates a table in the DB to hold the m2m relation. The intermediate model just makes this explicit. The only thing this changes in your code is that you can't do "my_datapoint.sensors.add(my_sensor)" anymore. You need to always create (and delete) a DatapointSensorRel explicitly. Erik -- You received this message because you are subscribed to the Google Groups "Django users" group.
