使用 django rest framework api 更新用户配置文件

Question

我想创建一个 API，用户可以在其中更新他们的个人资料。就我而言，用户可以更新他/她的用户名和密码。要更改他/她的个人资料，API 链接应为/api/change/usernameOfThatUser。当我在链接中使用不存在的用户名时，我仍然得到 userProfileChange API 页面，并且输入框没有填充以前的数据。我该如何解决这个问题？

serializers.py

User = get_user_model()

class UserProfileChangeSerializer(ModelSerializer):
    username = CharField(required=False, allow_blank=True, initial="current username")
    class Meta:
        model = User
        fields = [
            'username',
            'password',
        ]

    def update(self, instance, validated_data):
        instance.username = validated_data.get('username',instance.username)
        print('instance of username',instance.username)
        return instance 

views.py

class UserProfileChangeAPIView(UpdateAPIView):
    serializer_class = UserProfileChangeSerializer
    lookup_field = 'username'

urls.py

  url(r'^change/(?P<username>[\w-]+)$', UserProfileChangeAPIView.as_view(), name='changeProfile'),

也许尝试在您的 views.py 中执行类似的操作？

from rest_framework import generics, mixins, permissions

User = get_user_model()

class UserIsOwnerOrReadOnly(permissions.BasePermission):
    def has_object_permission(self, request, view, obj):
        if request.method in permissions.SAFE_METHODS:
            return True
        return obj.id == request.user.id

class UserProfileChangeAPIView(generics.RetrieveAPIView,
                               mixins.DestroyModelMixin,
                               mixins.UpdateModelMixin):
    permission_classes = (
        permissions.IsAuthenticated,
        UserIsOwnerOrReadOnly,
    )
    serializer_class = UserProfileChangeSerializer
    parser_classes = (MultiPartParser, FormParser,)

    def get_object(self):
        username = self.kwargs["username"]
        obj = get_object_or_404(User, username=username)
        return obj

    def delete(self, request, *args, **kwargs):
        return self.destroy(request, *args, **kwargs)

    def put(self, request, *args, **kwargs):
        return self.update(request, *args, **kwargs)

这将根据 url 中传递的用户名为您提供用户的所有现有数据。如果用户名不存在，则会引发 404 错误。您还可以更新或删除对象。
