CustomUserModel 没有 user_doctors

Question

我有临床操作的详细页面。我想让它仅可供与此操作相关的工作人员和医生使用 ManyToManyField 进行访问

为此，我这样做了

class OperationPanelView(LoginRequiredMixin,View):
    login_url = reverse_lazy("doctor:login")

    def get(self,request,id):
        operation = OperationModel.objects.get(id=id)

        if request.user.user_doctors not in operation.doctor.all():
            if DoctorModel.objects.filter(user = request.user).exists():
                return redirect("doctor:panel",request.user.id)
        elif request.user.is_staff == True:
            return redirect("disease:panel",operation.id)

        context = {
            "operation":operation,
        }
        return render(request,"operation_detail.html",context)

，如果 request.user.user_doctors 与此操作的医生不相关，那么它会将用户重定向到他们自己的面板。 如果 request.user.user_doctors 与手术医生相关，则页面将打开。

但如果用户是工作人员并给出了此错误，则不起作用：

RelatedObjectDoesNotExist at /disease/panel/1
CustomUserModel has no user_doctors.
in line 35: if request.user.user_doctors not in operation.doctor.all(): 

然后我添加此条件：

        if request.user.user_doctors:

但这也给出了相同的错误

DoctorModel：

class DoctorModel(models.Model):

    BLOOD_TYPE_CHOICES = [
        ("A+","A+"),
        ("A-","A-"),
        ("B+","B+"),

        ("AB-","AB-"),
    ]
 
    GENDER_CHOICES = [
        ("Male","Male"),
        ("Female","Female"),
    ]

    blood_type=models.CharField(choices=BLOOD_TYPE_CHOICES,max_length=10, null=True,blank=False)
    born_date = models.DateField(null=True,blank=False)

OperationModel：

class OperationModel(models.Model):
    name = models.CharField(null=True,blank=True,max_length=45)
    description = models.TextField(null=True,blank=True)
    disease = models.ManyToManyField(DiseaseModel,related_name="disease_operations")

    patient = models.ForeignKey("patients.PatientModel",on_delete=models.DO_NOTHING,related_name="patient_operations")
    is_active = models.BooleanField(default=True)

CustomUserModel：

class CustomUserModel(AbstractUser):
    username = None
    is_accepted = models.BooleanField(default=False)
    email = models.EmailField(_("email address"),unique=True)
    USERNAME_FIELD = "email"
    REQUIRED_FIELDS = []
    objects = CustomUserManager()

    class Meta:
        db_table = "user"
