如何使用Rest Framework在Django中序列化关系OneToOne？ [英] How to serialize a relation OneToOne in Django with Rest Framework?

问题描述

我有一个类PersonProfile和一个类Person。
在人类中，我与PersonProfile具有OneToOne关系。
我如何序列化呢？

I have a class PersonProfile, and a class Person. In the class Person i have a relationship OneToOne with PersonProfile. How can i Serialize that?

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")

推荐答案

您可以创建自定义序列化器字段来创建自定义PersonSerializer。
您可以添加字段以从环境获取值。

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
                 )

您还可以使用 serializers.ModelSerializer

class PersonSerializer(serializers.ModelSerializer):
