researchLines = models.CharField(max_length=200, blank=True)
loginName = models.CharField(max_length=50, blank=True)
class Person(models.Model):
profile = models.OneToOneField(PersonProfile)

You can create custom serializer fields to create your custom PersonSerializer.
You can add fields to get values from Enviroment.
class PersonSerializer(serializers.HyperlinkedModelSerializer):
interests = serializers.CharField(source='profile.interests')
researchLines = serializers.CharField(source='profile.researchLines')
loginName = serializers.CharField(source='profile.loginName')
# --- FIELDS FOR enviroment
class Meta:
model = Person
fields = ('interests', 'researchLines', 'loginName',
#-- enviroment fields
)
You can also use serializers.ModelSerializer
class PersonSerializer(serializers.ModelSerializer):

I recently stumbled upon something similar and here is what I did for serializing the Person which is in OneToOne relation with PersonProfile.
class PersonProfileSerializer(serializers.ModelSerializer):
class Meta:
model = PersonProfile
fields = __all__ # in your case since you are using all fields.
class PersonSerializer(serializers.ModelSerializer):
person = PersonProfileSerializer(required=True)
class Meta:
model = Person
fields = __all__
# Now override the default create method to create a new object.
# A similar overriding can be done for update as well.
def create(self, validated_data):
"""
Make necessary modifications as per your requirements
"""
person_profile = PersonProfileSerializer.create(PersonProfileSerializer(), validated_data)
person, created = Person.objects.create(profile=person_profile)
return person
