如何使用 Rest Framework 在 Django 中序列化 OneToOne 关系？

Question

我有一个 class PersonProfile 和一个 class 人物。在 class Person 中，我与 PersonProfile 建立了 OneToOne 关系。我如何序列化它？

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

class Person(models.Model):
    profile = models.OneToOneField(PersonProfile)
    enviroment = models.ForeignKey(Enviroment, related_name="persons")

Answer 1

您可以创建自定义序列化程序字段来创建您的自定义 PersonSerializer。您可以添加字段以从 Enviroment.

获取值

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
                 )

您也可以使用serializers.ModelSerializer

class PersonSerializer(serializers.ModelSerializer):
   #-------------------------

Answer 2

我最近偶然发现了类似的东西，这就是我序列化与 PersonProfile 具有 OneToOne 关系的 Person 的方法。

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
