必填字段驗證程序在azure上的Django中不起作用

Question

我有一個簡單的註冊表單。人們可以填寫信息並提交表格時，數據應該存入數據庫。

該應用程序在我的本地主機上正常工作。我的表單中有一些必填字段。當我在本地主機上運行應用程序時，我嘗試提交沒有填寫必填字段的表單，然後顯示一個彈出窗口，並說**該字段不能爲空**，但是當我將其部署到我的天藍色門戶時，試圖挽救這個沒有填寫必填字段，然後它會產生錯誤：

    else:

    return render(request, 'registration/register.html',variables) 

Answer 1

您還沒有在任何地方撥打is_valid。它應該是：

if request.method == 'POST': 
    form = UserInformationForm(request.POST) 
    if form.is_valid(): 
     form.save() 
     return HttpResponseRedirect('/register/success/')
