+this is my model (autogenerated from an existing database):
+class TrtMeasurements(models.Model):
+    observation = models.OneToOneField('TrtObservations', models.DO_NOTHING, primary_key=True)
+    measurement_type = models.ForeignKey(TrtMeasurementTypes, models.DO_NOTHING, db_column='measurement_type')
+    measurement_value = models.FloatField()
+    comments = models.TextField(blank=True, null=True)
+    class Meta:
+        managed = False
+        db_table = 'trt_measurements'
+        unique_together = (('observation', 'measurement_type'),)
 While this makes sense for a single unique primary key, it is the wrong behavior for a composite primary key.
