我目前有一個(gè)稱為服務(wù)的模型，顯示在這里...class Services(models.Model): service_sku = models.AutoField(primary_key=True) name = models.CharField(max_length=200, null=True) price = models.FloatField(null=True)forms.pyclass ServiceForm(forms.ModelForm): class Meta: model = Services fields = '__all__'基于上面顯示的代碼，我有兩個(gè)視圖，一個(gè)將創(chuàng)建上面模型的實(shí)例，另一個(gè)視圖將更新實(shí)例，如下所示def NewServices(request): form = ServiceForm() if request.method == 'POST': form = ServiceForm(request.POST or None) if form.is_valid(): form.save() return redirect('/') return render(request, 'accounts/new_services.html', {'form': form})def EditServices(request,pk): service = Services.objects.get(service_sku=pk) form = ServiceForm(instance=service) if request.method == 'POST': form = ServiceForm(request.POST, instance=service) if form.is_valid(): form.save() return redirect('/') context = {'form':form} return render(request, 'accounts/edit_services.html',context)模板如下<div class="row"> <div class="col-md-7"> <div class="card card-body"> <form action="" method="POST"> {% csrf_token %} {{form}} <hr> <input type="submit" name="Update"> </form> </div> </div></div>是否可以在我的模板表單中顯示 service_sku 的 readyonly，當(dāng)實(shí)例需要更新時(shí)以及 service_sku readonly 在創(chuàng)建實(shí)例時(shí)顯示為在模板中自動生成？

是的。您可以在表單中包含該字段，因此您可能應(yīng)該制作一個(gè)單獨(dú)的表單來更新：
class ServiceEditForm(forms.ModelForm):
service_sku = forms.IntegerField(disabled=True)
class Meta:
model = Services
fields = ('service_sku', 'name', 'price')
在表單中，您只需使用該新表單：
def EditServices(request,pk):
service = Services.objects.get(service_sku=pk)
if request.method == 'POST':
form = ServiceEditForm(request.POST, request.FILES, instance=service)
if form.is_valid():
form.save()
return redirect('/')
else:
form = ServiceEditForm(instance=service)
context = {'form':form}
return render(request, 'accounts/edit_services.html', context)
使用disabled=True[Django-doc]不僅可以確保該字段在客戶端被禁用，而且還可以防止有人發(fā)出惡意的 POST 請求。
