简单例子：
1 #自定义验证类 2 class Check_form1(forms.Form): 3 #user就是要验证的字段,这里对应前端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()表单验证,全通过返回True,有错误就false 18 result = obj.is_valid() 19 if result: 20 21 #{‘pwd‘: u‘12311‘, ‘user‘: u‘12311‘, ‘email‘: u‘123@11.com‘} 22 print(obj.cleaned_data) 23 else: 24 #打印错误字段 25 #如:<ul class="errorlist"><li>pwd<ul class="errorlist"><li>最小4位</li></ul></li></ul> 26 #返回json格式错误:obj.errors.as_json() 27 # {"pwd": [{"message": "\u6700\u5c0f4\u4f4d", "code": "min_length"}]} 28 print(obj.errors) 29 return HttpResponse("ok")
