Django self.request.POST.get() 返回 None

Question

我正在尝试为我的数据库创建一个搜索按钮。但是我的 self.request.POST.get('searched') 正在返回 None

表格：

<form class="d-flex" action="{% url 'asset_app_search' %}">{% csrf_token %}
        <input class="form-control me-2" type="search" placeholder="Søg" aria-label="Search" name="searched">
        <button class="btn btn-outline-secondary" type="submit">Søg</button> -
      </form>

我的views.py

class SearchView(generic.TemplateView):
    template_name = "asset_app/search.html"

    def post(self):
        searched = self.request.POST.get('searched')

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        searched = self.post()
        context['searched'] = searched
        context_entry_today = datetime.date.today()
        context_entry_overdue = datetime.date.today() - datetime.timedelta(days=90)
        context_entry_inspection_time = datetime.date.today() - datetime.timedelta(days=76)
        context['assets'] = models.Asset.objects.order_by('name')
        context['rooms'] = models.Room.objects.order_by('last_inspected', 'location', 'name')
        context['bundelReservations'] = models.Bundle_reservation.objects.order_by('return_date')
        context['loan_assets'] = models.Loan_asset.objects.order_by('return_date')
        context['to_dos'] = to_do_list_app.models.Jobs.objects.all()
        context['today'] = context_entry_today
        context['overdue'] = context_entry_overdue
        context['inspection_time'] = context_entry_inspection_time
        return context

以及正在发布的内容

您应该让表单发出 POST 请求，其中：

<form <b>method="post"</b> class="d-flex" action="{% url 'asset_app_search' %}">{% csrf_token %}
    …
</form>

因此您在 <form> 标签中指定 method="post"。

在您看来，您的 post 方法最终将不得不 return 一个 HttpResponse 对象：

class SearchView(generic.TemplateView):
    template_name = "asset_app/search.html"

    def post(self):
        searched = self.request.POST.get('searched')
        # …
        <b>return HttpResponse('<i>some message</i>')</b>
