  • form表单校验放在装饰器中，校验失败返回状态码422
  • 请求参数校验必须使用Form进行校验，具体参见Forms
  • 除文件或其他二进制数据外，返回的内容都是json格式的数据
class PersonsView(View):
    @login_required()
    @form_valid(PersonsGetForm)
    def get(self, request):
        data = request.valid_data
        q = Q()
        ...
        persons = Person.objects.filter(q)
