如何从 Django 序列化程序中的 jwt 令牌访问请求的用户对象?
How to access requested user object from jwt token in django serializers?
After user-registration, user wants to post data into Client model ( OnetoOne relationship with User model ). So, I want to access the requested user object inside the serializer-class to create a new row in Client model associated with the requested user.
models.py
class Client(models.Model):
user= models.OneToOneField(User, on_delete=models.CASCADE, null=False, blank=False)
sex = models.CharField(max_length = 6, blank=False, null=False)
location = models.CharField(max_length = 30, null = False, blank = False)
views.py
class ClientRegister(GenericAPIView):
def post(self, request):
user = request.user
serializer = ClientSerializer(data= request.data)
if serializer.is_valid():
serializer.save()
return Response(status= status.HTTP_201_CREATED)
else:
return Response(data= 'Invalid Form', status= status.HTTP_400_BAD_REQUEST)
serializers.py
class ClientSerializer(serializers.ModelSerializer):
class Meta:
model = Client
fields = ['sex', 'location']
def create(self, validated_data):
sex = validated_data.get('sex')
location = validated_data.get('location')
user = #------ Want requested user object here ------#
if user.is_client:
client = Client(user=user, sex=sex, location=location)
client.save()
return client
I have manually added user oject into the data in serializer = CientSerializer(data=request.data)
.
But, It didn't work. Please, tell me how to pass it from views.py
or how to access it in serializers.py
.

class ClientRegister(GenericAPIView):
def post(self, request):
data = request.data
user = request.user
#add user in key
data['user']=user
serializer = ClientSerializer(data=data)
if serializer.is_valid():
serializer.save()
return Response(status= status.HTTP_201_CREATED)
else:
return Response(data= 'Invalid Form', status= status.HTTP_400_BAD_REQUEST)
序列化器:
class ClientSerializer(serializers.ModelSerializer):
class Meta:
model = Client
fields = '__all__'
当您在 post 视图方法中执行 serializer.save 时传递用户
def post(self, request):
u = request.user
serializer = ClientSerializer(data= request.data)
if serializer.is_valid():
serializer.save(user=u)
return Response(status= status.HTTP_201_CREATED)
else:
return Response(data= 'Invalid Form', status= status.HTTP_400_BAD_REQUEST)
或者您可以阅读有关将上下文从视图传递到序列化程序的信息,在这种情况下,您可以传递所需的数据,例如 -
serializer = ClientSerializer(context = {'request':request}, data=request.data)
然后你可以在你的序列化器中有你的请求对象,你可以得到request.user或者直接在上下文中传递它。
views.py
class ClientRegister(GenericAPIView):
def post(self, request):
user = request.user
serializer = ClientSerializer(context={'user':user}, data= request.data)
if serializer.is_valid():
serializer.save()
return Response(status= status.HTTP_201_CREATED)
