错误名称:字段名称user_username
对模型Profile
我正在构建我的编辑个人资料视图。
这是我的views.py
class ProfileEditAPIView(DestroyModelMixin, UpdateModelMixin, generics.RetrieveAPIView):
serializer_class = ProfileEditSerializer
def get_queryset(self):
logged_in_user = User.objects.filter(username=self.request.user.username)
return logged_in_user
def get_object(self):
queryset = self.get_queryset()
obj = get_object_or_404(queryset)
return obj.profile
def put(self, request, *args, **kwargs):
return self.update(request, *args, **kwargs)
def delete(self, request, *args, **kwargs):
return self.destroy(request, *args, **kwargs)
我可以正确获取user_id,但无论如何我无法访问其用户名字段
这是serializers.py
class ProfileEditSerializer(serializers.ModelSerializer):
class Meta:
model = Profile
fields = (
'user_username', <<<
'title',
'gender',
'birth',
'height',
'height_in_ft',
'profile_img',
)
models.py
class Profile(models.Model):
user = models.OneToOneField(settings.AUTH_USER_MODEL)
title = models.TextField(max_length=155, blank=True)
gender = models.CharField(max_length=10, choices=GENDER_CHOICES, default='u') # Recommend Factor
location = models.CharField(max_length=40, choices=LOCATION_CHOICES, default='ud') # Recommend Factor
birth = models.DateField(default='1992-07-23', blank=True, null=True) # Recommend Factor
height = models.CharField(max_length=5, default='undefined')
height_in_ft = models.BooleanField(default=True)
profile_img = models.ImageField(
upload_to=upload_location,
null=True,
blank=True)
为什么我们无法访问用户的用户名?我们如何解决这个问题?

您可以使用此方式从username
模型中获取User
。
class ProfileEditSerializer(serializers.ModelSerializer):
username = serializers.CharField(read_only=True, source="user.username")
class Meta:
model = Profile
fields = (
'username',
'title',
. . . .
)

尝试调用用户名,就像在模型中查看用户名一样。
更改:
fields = (
'user_username', <<<
'title',
'gender',
'birth',
'height',
'height_in_ft',
'profile_img',
)
收件人:
fields = (
'user',
'title',
'gender',
'birth',
'height',
'height_in_ft',
'profile_img',
)
但是,如果您希望它在json响应中显示为用户名,请使用:
class ProfileEditSerializer(serializers.ModelSerializer):
username = serializers.CharField(source='user')
class Meta:
model = Profile
fields = (
'username', <<<
'title',
'gender',
'birth',
'height',
'height_in_ft',
'profile_img',
)
