python - Django 休息 : create CRUD operations for OneToOne Field

Question

我正在尝试为 OneToOne 字段创建基本的 CRUD 操作。用户在登录时不需要设置配置文件。如何在需要时创建/更新/删除配置文件(假设用户已经在数据库中)？

我的模型是来自 Django REST 的默认用户模型，并且:

class UserProfile(models.Model):
        user = models.OneToOneField(User)
        location = models.CharField(max_length=50,blank=True)
        title = models.CharField(max_length=80,blank=True)
        #picture = models.ImageField(upload_to='user_imgs', blank=True)
        website = models.URLField(blank=True)

我的 View 集是:

class UserViewSet(viewsets.ModelViewSet):
    queryset = User.objects.all()
    serializer_class = UserSerializer
    filter_fields = ['id', 'username', 'email', 'first_name', 'last_name']

class UserProfileViewSet(viewsets.ModelViewSet):
    queryset = UserProfile.objects.all()
    serializer_class = UserProfileSerializer
    filter_fields = ['user_id', 'location', 'title', 'website']

并序列化:

class UserSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = User
        email = serializers.EmailField()
        fields = ('id','username', 'email', 'first_name', 'last_name')


class UserProfileSerializer(serializers.HyperlinkedModelSerializer):
    user_id = serializers.CharField(source='user.id')

    class Meta:
        model = UserProfile
        fields = ('user_id', 'location','title','website')

我相信您希望将配置文件创建限制为当前登录的用户。您可以过滤当前用户的个人资料查询集，这样只有该用户的个人资料才能被登录用户访问。

class UserViewSet(viewsets.ModelViewSet):
    queryset = User.objects.all()
    serializer_class = UserSerializer
    filter_fields = ['id', 'username', 'email', 'first_name', 'last_name']


class UserProfileViewSet(viewsets.ModelViewSet):
    queryset = UserProfile.objects.all()
    serializer_class = UserProfileSerializer
    filter_fields = ['user_id', 'location', 'title', 'website']

    def get_queryset(self):
        return super(UserProfileViewSet, self).get_queryset().filter(
            user=self.request.user)

    def perform_create(self, serializer):
        serializer.save(user=user)

您将 user 字段设为只读，并保存在上述方法 perform_create 中，并始终分配给当前用户。

class UserProfileSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = UserProfile
        fields = ('user', 'location','title','website')
        read_only_fields = ('user',)
