Django Rest Framework : how to specify a serializer to use different fields to create, update and get

I have a doubt with the serializers and so far I have not been able to solve it. I explain the doubt with the following example:

I have a User model and this model has the following attributes: username, password, first_name, last_name, age, gender. I also have a serializer, which is called UserSerializer. The UserSerializer should do the following:

My solution:

class UserSerializer:

    class UserCreateSerializer(serializers.ModelSerializer):
        class Meta:
            model = User
            fields = ['username', 'password', 'first_name', 'last_name']

    class UserGetSerializer(serializers.ModelSerializer):
        class Meta:
            model = User
            fields = ['age', 'gender']

    class UserUpdateSerializer(serializers.ModelSerializer):
        class Meta:
            model = User
            fields = ['password']

Question:

The question: is there any way to synthesize the three serializers into one, or what is the best solution for this problem?

Thank you very much.

Use write_only and read_only parameters in serializer fields to specify fields for creating and retrieving

class UserSerializer(serializers.ModelSerializer):
    username = serializers.CharField(write_only=True, required=False)
    password = serializers.CharField(write_only=True)
    first_name = serializers.CharField(write_only=True, required=False)
    last_name = serializers.CharField(write_only=True, required=False)
    age = serializers.IntegerField(read_only=True)
    gender = serializers.CharField(read_only=True)


    class Meta:
        model = User
        fields = ['username', 'password', 'first_name', 'last_name', 'age', 'gender']

If any field is optional, then you can add the required=False
