任何在post方法中访问动态url的直接方法

Question

在views.py

class ProcessMessage(TemplateView):
     template_name = 'chat/chat.html'

    def get_object(self):
        id=self.kwargs.get('pk')
        obj=None
        if id is not None:
            obj= User.objects.get(pk=id)

        return obj

    def get(self, request, pk=None,*args, **kwargs):

        obj=self.get_object()
        print(obj,pk)
        super(ProcessMessage, self).get(request, *args, **kwargs)
        return render(request, self.template_name, {'form': ChatForm()})

   def post(self, request, pk=None,*args, **kwargs):
        obj=self.get_object()
        pk=pk
        print(pk)
        print('obj is',obj)
        form = ChatForm(data=request.POST)

        # log = logging.basicConfig(level=logging.DEBUG)

        # print('post from index')
        if form.is_valid():
         //////something////

在urls.py中

app_name = 'chatbot'
urlpatterns = [
    path('demo', views.ProcessMessage.as_view(), name='index'),
    path('<uuid:pk>/demo', views.ProcessMessage.as_view(), name='index'),
]

我正在get方法中获取obj和pk的值，但我也想要post方法中的那些值（当前获取值是None）

我需要def Post方法中URL的id / pk来获取用户信息（不，我不想使用request.user）

模板：

{% extends 'chat/base.html' %}
{% load static %}

{% block head %}

    <script type="text/javascript" src="{% static 'chat/js/somejavascript.js' %}"></script>

    <style>

        body {
            overflow-x: hidden !important;
            -ms-overflow-x: hidden !important;
        }

        /* width */
        ::-webkit-scrollbar {
            width: 0;
            background-color: transparent;
        }


        .btn-rounded {
            border-radius: 30px;
            font-size: 12px;
            border-color: #3741e5;
        }

      .msg-btn{
          font-size: 10px !important;
          margin-bottom: 0;
          padding-top: 3px!important;

Answer 1

您的模板显示您正在将表单提交到不带pk的URL：

{% url 'chat:index' %}

例如，在反转URL时，您应该包括pk

{% url 'chat:index' pk %}

例如，您需要在模板上下文中包含pk

return render(request, self.template_name, {'form': ChatForm(), 'pk': pk})

[我看到您对ProcessMessage和/demo/使用了相同的视图/<pk>/demo/。我建议对两个URL使用不同的视图，我认为这将有助于避免出现此类问题。
