Wrong data passed to the nested serializer

[sommelon]

Describe what you are trying to accomplish

I'm trying to create a nested object with a foreign key relation.

Relevant models

I'll illustrate the error on the models Phone and Student from the testapp

Relevant serializers

class NestedStudentSerializer(DynamicFieldsMixin, serializers.ModelSerializer):
    class Meta:
        model = Student
        fields = '__all__'

class NestedPhoneSerializer(DynamicFieldsMixin, NestedModelSerializer):
    student = NestedField(NestedStudentSerializer)
    class Meta:
        model = Phone
        fields = '__all__'

Request body

{
    "number": "0909090900",
    "type": "personal",
    "student": {
        "name": "John Depp",
        "age": 45,
        "course": 2
    }
}

What's the result?

Data that gets passed to the nested serializer is converted to the native representation and I get this error.

{'course': ['Incorrect type. Expected pk value, received Course.']}

Versions django = "==2.2.24" djangorestframework = "==3.12.2"

I created a fork with a test here
