Showing the read_only fields in the serializer in the post /swagger template in (ForignKeyFields)

[SamiTalebian]

class MatchSerializer(serializers.ModelSerializer):
winner = AthleteWinnerSerializer(read_only=True)
class Meta:
model = Match
fields = ['uid', 'round_one', 'round_two', 'round_three', 'winner']

In this example the winner is generated in the body of the post api like the example below :

{
"round_one": "3fa85f64-5717-4562-b3fc-2c963f66afa6",
"round_two": "3fa85f64-5717-4562-b3fc-2c963f66afa6",
"round_three": "3fa85f64-5717-4562-b3fc-2c963f66afa6",
"winner": {
"username": "string"
}
}
