使用Django模板标签的Mako模板(Mako templates using Django template tags)

 我想你将使用Django的默认用户模型作为OneToOneField与您的自定义用户模型。 用户模型不需要其他序列化程序。 由于额外的字段将在CustomUser中，因此仅为自定义用户编写序列化程序就足够了。 
 
from django.contrib.auth.models import User
class CustomUser(models.Model):
    user = models.OneToOneField(User)
    # Add your extra fields here.
 
 这是你如何做到的： 
 
CustomUserSerializer(serializers.ModelSerializer):
    username = Serializers.CharField(source='user.username')
    email = Serializers.EmailField(source='user.email')

    class Meta:
        model = CustomUser
        fields = ('username', 'email', 'extra_fields_from_CustomUser',)
 
 值得庆幸的是， source允许您轻松访问OneToOneField，以便您不需要任何其他内容。 

I guess you're going to use Django's default User model as an OneToOneField with your custom User Model. You don't need another serializer for User model. Since extra fields will be in CustomUser, it's enough to write a serializer for only Custom User.
 
from django.contrib.auth.models import User
class CustomUser(models.Model):
    user = models.OneToOneField(User)
    # Add your extra fields here.
 
This is how you do it:
 
CustomUserSerializer(serializers.ModelSerializer):
    username = Serializers.CharField(source='user.username')
    email = Serializers.EmailField(source='user.email')

    class Meta:
        model = CustomUser
        fields = ('username', 'email', 'extra_fields_from_CustomUser',)
 
Thankfully, source lets you to reach your OneToOneField easily so that you don't need anything else.
