Description

As discussed {1} I propose following changes to natural keys (de)serialization documentation {2}:

1) mention requirement to use tuple also in natural keys/serialization section (currently this is only mentioned in deserialization).

  • For example: "A natural key is a tuple of values that can be used to uniquely identify an object instance without using the primary key value"

2) in the example model define Person first_name and last_name as unique_together.

  • For example: "class Meta: unique_together = (("first_name", "last_name"),)"
