如何使用 DjangoRestFramework 序列化为多个模型 [英] How to serialize into multiple models using DjangoRestFramework

问题描述

我已经定义了一个用户配置文件模型，但想要有一个 api 端点来将所有用户数据保存到两个模型中.我的意思是，我正在使用用户模型，并且我有一个定义如下的用户配置文件模型

I have defined a user profile model, but want to have one api endpoint that saves all of the user data into both models. By that I mean, I am using the user model and I have a userprofile model defined as follows

class UserProfile(models.Model):
    user = models.OneToOneField(settings.AUTH_USER_MODEL)
    biography = models.TextField()

当我定义一个用于创建新用户的序列化程序时，如何让它将数据序列化到用户模型和 userProfile 模型中?

when I define a serializer for creating a new user, how do I get it to serialize data into both the user model, and the userProfile model?

推荐答案

你只需要为每一个定义一个序列化器，并将一个附加到另一个，如下:

You just need to define a serializer for each, and attach one to the other, as follows:

from rest_framework.serializers import ModelSerializer

class UserSerializer(ModelSerializer):
    """
    A serializer for ``User``.
    """
    class Meta(object):
        model = User


class UserProfileSerializer(ModelSerializer):
    """
    A serializer for ``UserProfile``.
    """
    user = UserSerializer()

    class Meta(object):
        model = UserProfile

然后您可以使用 UserProfileSerializer 更新(或执行其他操作)用户配置文件及其用户实例.

You could then use UserProfileSerializer to update (or perform other actions to) a user profile and its user instance.
