1 #自定義驗證類 2 class Check_form1(forms.Form): 3 #user就是要驗證的字段,這裏對應前端name <input type=‘text‘ name=user> 4 user = fields.CharField() 5 pwd = fields.CharField() 6 email = fields.EmailField() 7 8 9 10 def test_form1(request): 11 if request.method == ‘GET‘: 12 return render(request,‘form1.html‘) 13 14 elif request.method == ‘POST‘: 15 obj = Check_form(request.POST) 16 17 #obj.is_valid()表單驗證,全通過返回True,有錯誤就false 18 result = obj.is_valid() 19 if result: 20 21 #{‘pwd‘: u‘12311‘, ‘user‘: u‘12311‘, ‘email‘: [email protected]
