How to change DRF API SlugRelatedField Response template - django

Question

I have managed to create a working model with 2 different serializers, depending on what we are doing. Right now, ReadTitleSerializer returns the below JSON object:
[
{
"id": 1,
"category": {
"id": 1,
"name": "Movies",
"slug": "movie"
},
"genres": [
{
"id": 1,
"name": "Drama",
"slug": "drama"
}
],
"name": "Drama Llama",
"year": "1998-02-02",
"description": null,
"rating": null
}
]
And this is the response from WriteTitleSerializer:
{
"id": 1,
"category": "movie",
"genres": [
"drama"
],
"name": "Drama Llama",
"year": "1998-02-02",
"description": null,
"rating": null
}
How can I make WriteTitleSerializer respond similarly to ReadTitleSerializer? I am using SlugRelatedField in WriteTitleSerializer because the JSON input should be a list of slugs.
Input JSON
{
"name": "Drama Llama",
"year": "1998-02-02",
"category": "movie",
"genres": [
"drama"
]
}
serializers.py
class ReadTitleSerializer(serializers.ModelSerializer):
category = CategorySerializer()
genres = GenreSerializer(many=True)
class Meta:
model = Title
fields = '__all__'
read_only_fields = ('category', 'genres')
class WriteTitleSerializer(serializers.ModelSerializer):
category = SlugRelatedField(
slug_field='slug',
queryset=Category.objects.all(),
required=True
)
genres = SlugRelatedField(
slug_field='slug',
queryset=Genre.objects.all(),
many=True,
required=True
)
class Meta:
model = Title
fields = '__all__'
