Python Django编辑模型实例

我正在处理的Django项目列出了患者的详细信息，并允许用户编辑详细信息。我已经能够列出它，但是

views.py

没有链接到更新列表的url

视图.py：

    def update_patient(request, patient_id):
        patient = Patient.objects.get(id=patient_id)
        if request.method != 'POST':
            form = PatientForm(instance=patient)
        else:
            # POST data submitted; process data.
            form = PatientForm(instance=patient, data=request.POST)
            if form.is_valid():
                form.save()
                return HttpResponseRedirect(reverse('patient:patient',
                                            args=[patient.id]))
    context = { 'patient': patient, 'form': form}
    return render(request, 'patient/update_patient.html', context)

  class Patient(models.Model):
      patientID = models.CharField(max_length=20)
      firstName =models.CharField(max_length=20)
      lastName = models.CharField(max_length=20)
      age = models.IntegerField(max_length=None)
      SSN = models.CharField(max_length=15)
      address = models.CharField(max_length=200)
      date_added = models.DateTimeField(auto_now_add=True)

url(r'^patients/(?P<patient_id>\update\d+)/$', views.update_patient, name='update'),
