Answer 1

[
    {
        "id": 1,
        "key_name": "first cat",
        "display_name": "first cat",
        "images": [
            {
                "image": "http://localhost:8000/ImagesCat/Screenshot_from_2022-12-21_18-16-28.png"
            },
            {
                "image": "http://localhost:8000/ImagesCat/Screenshot_from_2022-12-29_13-41-31.png"
            }
        ]
    }
]

this is how I get response if you want to make like yours then you have to override list method

from rest_framework import serializers

from app.models import Cat_Image, Cat_Breed_Detail


class CatImageSerializer(serializers.ModelSerializer):
    class Meta:
        model = Cat_Image
        fields = '__all__'


class CatImageSerializer2(serializers.ModelSerializer):
    class Meta:
        model = Cat_Image
        fields = ['image']


class CatDataSerializer(serializers.ModelSerializer):
    images = CatImageSerializer2(read_only=True, many=True)

    class Meta:
        model = Cat_Breed_Detail
        fields = ['id', 'key_name', 'display_name', 'images']

Answer 2

i just override the serialize data like this :

for d in seri.data:
         d.update({'images': [nest_d['image'] for nest_d in d['images']]})
