创建模型实例

Question

我有两个模型，(Doctor & Patient)，Doctor 模型是父母模型，如何使Service_doctor 字段成为Doctor 模型的实例，以便我可以将Doctor 的名称添加到Patient 的模型中使用for循环在 HTML 模板中。这就是我想表达的意思；

模型.py

class Doctor(models.Model):
        Doctor_Name = models.CharField(max_length=200)

        def __str__(self):
        return self.Doctor_Name

class Patient(models.Model):
        Name = models.CharField(max_length=200)
        Telephone = models.CharField(max_length=100, unique=True)
        Service_doctor = models.ForeignKey(Doctor, on_delete=CASCADE)
        def __str__(self):
        return self.Doctor_Name

视图.py

def Newpatient(request):
    if request.method == 'POST':         

        Name = request.POST.get('Name')
        Telephone = request.POST.get('Telephone')
        Service_doctor = request.POST.get('Service_doctor')

        formdata = Patient(Name=Name, Telephone=Telephone, Service_doctor=Service_doctor)
        formdata.save()

        return render(request, 'Adm.html')

任何帮助表示赞赏。

Answer 1

这将在患者下创建一个新记录：

dr = Doctor.object.filter(id = pk)

patient = Patient(
       name = 'John Doe'
       telephone = '123456786'
       service_doctor = dr
       )
