我正在为一家医疗公司做一个CRUD，我试图从某个医生那里展示专业，但当他们有多个时我试图将这个对象作为一个列表（我得到它）
但是当我尝试将其传递给模板时，它会失败，我该怎么办？
这是我的观点
def UpdatePhysician(request,id):
physician = get_object_or_404(Physician, id=id)
employee = get_object_or_404(Employee, id=physician.employee.id)
person = get_object_or_404(Person, id=employee.person.id)
try:
address = get_object_or_404(Address, id=return_id(str(person.addresses.values('id'))))
except:
address = None
try:
email = get_object_or_404(Email, id=return_id(str(person.emails.values('id'))))
except:
email = None
try:
phone = get_object_or_404(PhoneNumber, id=return_id(str(person.phone_numbers.values('id'))))
except:
phone = None
try:
academic_degree = get_object_or_404(AcademicDegree, id=return_id(str(employee.academic_degrees.values('id'))))
university = get_object_or_404(University, id=return_id(str(employee.academic_degrees.values('university'))))
except:
academic_degree = None
university = None
physician_specialties = get_list_or_404(PhysicianSpecialties, employee_academic_degree__employee__pk=physician.employee.id)
for item in physician_specialties:
print(unicode(item.specialty))
physician_specialties_form = PhysicianSpecialtiesForm(request.POST or None, instance=physician_specialties)
specialties = Specialty.objects.all()
specialty = PhysicianSpecialties.objects.filter(employee_academic_degree__employee__physician__pk=id)
academic_degree = EmployeeAcademicDegree.objects.filter(employee__physician__pk=id)
person_form = PersonForm(request.POST or None, instance=person)
employee_form = EmployeeForm(request.POST or None, instance=employee)
physician_form = PhysicianForm(request.POST or None, instance=physician)
email_form = EmailForm(request.POST or None, instance=email)
address_form = AddressForm(request.POST or None, instance=address)
phone_form = PhoneForm(request.POST or None, instance=phone)
academic_degree_form = AcademicDegreeForm(request.POST or None, instance= academic_degree)
university_form = UniversityForm(request.POST or None, instance=university)
if (person_form.is_valid() and employee_form.is_valid() and physician_form.is_valid() and email_form.is_valid() and
address_form.is_valid() and phone_form.is_valid and physician_form.is_valid() and university_form.is_valid and
academic_degree_form.is_valid()):
person_form.save()
physician_form.save()
academic_degree_form.save()
new_address = address_form.save()
new_email = email_form.save()
new_phone = phone_form.save()
university_form.save()
if address == None:
PersonAddress.objects.create(person=person, address=new_address)
if email == None:
PersonEmail.object.create(person=person, email=new_email)
if phone == None:
PersonPhoneNumber.objects.create(person=person, hone_number=new_phone)
return HttpResponse('yesh')
return render(request, 'UpdatePhysician.html', {'person_form': person_form,
'employee_form': employee_form,
'email_form': email_form,
'phone_form': phone_form,
'address_form': address_form,
'physician_form': physician_form,
'specialty': specialty,
'academic_degree_form': academic_degree_form,
'academic_degree': academic_degree,
'university_form':university_form,
'specialties': specialties,
'physician_specialties_form': physician_specialties_form,
})
问题存在于
中physician_specialties = get_list_or_404(PhysicianSpecialties, employee_academic_degree__employee__pk=physician.employee.id)
for item in physician_specialties:
print(unicode(item.specialty))
physician_specialties_form = PhysicianSpecialtiesForm(request.POST or None, instance=physician_specialties)
