我想将登录用户的 user_company 的值分配给新创建用户的 user_company 字段
I want to assign value of logged in user's user_company to the user_company field of the newly created user
当用户为客户端创建用户记录时,新客户端应具有当前登录用户的 User.user_company
值。
这里的问题,我想在视图中调用save()
时,将登录用户的User.user_company的值赋给新用户的clientuser.user_company
。
下面是带有 clientuser
对象的序列化程序。
class ClientSerializers(serializers.ModelSerializer):
password2 = serializers.CharField(style={'input_type': 'password'}, write_only=True)
client_name = serializers.CharField(style={'input_type' : 'text'}, required=True)
class Meta:
model = User
fields = ['email', 'username', 'password', 'password2', 'user_type', 'client_name']
extra_kwargs = {
'password': {'write_only': True}, #dont want anyone to see the password
'user_type': {'read_only': True},
}
def save(self):
clientuser = User(
#creating a user record. it will record company fk
email=self.validated_data['email'],
username=self.validated_data['username'],
user_type = 3,
first_name = self.validated_data['client_name'])
#validating the password
password = self.validated_data['password']
password2 = self.validated_data['password2']
if password != password2: #trying to match passwords.
raise serializers.ValidationError({'password': 'Passwords must match.'})
clientuser.set_password(password) #setting the password
clientuser.save() #saving the user
return clientuser
我试过使用
cur_usr = User()
param = 'user_company'
usr_comp = getattr(u, param)
print(f'usr_comp is {usr_comp})
print 语句在终端中打印 usr_comp is None
我也试过使用
curr_User_Company = User.user_company
user.user_company = curr_User_Company
它returns终端中的以下行
raise ValueError(
ValueError: Cannot assign "<django.db.models.fields.related_descriptors.ForwardManyToOneDescriptor object at 0x04B05F28>": "User.user_company" must be a "Company" instance.
这是我的用户模型
class User(AbstractUser):
email = models.EmailField(verbose_name="email", max_length=60, unique=True)
user_type_data = ((1,"sysAdmin"),(2,"CompanyAdmin"), (3,"Client"), (4,"Employee"))
user_type = models.IntegerField(choices=user_type_data, default=2)
user_company = models.ForeignKey('Company', on_delete=models.CASCADE, null=True, blank=True)
#if user is CompAdmin then company is the company he belongs to
#if user is Client then company is the company he is serviced by
#if user is Employee then company is the company he works for
#if user is sysAdmin then company is null
这是我的看法

if request.method == 'POST':
data = JSONParser().parse(request)
serializer = ClientSerializers(data=data)
if serializer.is_valid():
serializer.save()
return JsonResponse(serializer.data, status=201)

我不确定这是否有必要,但如果有必要,这里是我尝试通过 Postman 传递的数据示例
{
"email":"Maximillian@amgracing.com",
"username":"Maximillian",
"password":"AmgRacingBetterThanRedBull",
"password2":"AmgRacingBetterThanRedBull",
"client_name" : "MaximillianRacing"
}
也许你应该使用这个:
from django.contrib.auth import get_user
还有这个:
clientuser = User(
#creating a user record. it will record company fk
email=self.validated_data['email'],
username=self.validated_data['username'],
///
user_company = get_user(self.request).user_company /// this line get you user_company from logged user
终于想通了。我将 current_user 参数添加到 save()
函数并将 user_company 分配给 current_user.user_company
的值
def save(self, current_user):
usr_comp = current_user.user_company
clientUser = User(///
user_company = usr_comp)
在 ClientApi
视图中,这是我所做的
serializer.save(current_user = request.user)
当用户为客户端创建用户记录时,新客户端应具有当前登录用户的 User.user_company
值。
