Question

对HTML＆amp;表格在这里

http://www.django-rest-framework.org/topics/html-and-forms/

我有以下名为dashboard / widget_detail.html

的模板

{％load rest_framework％}

<html><body>

<h1>Profile - {{ widget.name }}</h1>

<form action="{% url 'widget-detail' pk=widget.pk %}" method="POST">
    {% csrf_token %}
    {% render_form serializer %}
    <input type="submit" value="Save">
</form>

</body></html>

以下观点 -

class WidgetDetail(APIView):
    renderer_classes = [TemplateHTMLRenderer]
    template_name = 'dashboard/widget_detail.html'

    def get(self, request, pk=None):
        widget= get_object_or_404(Password, pk=pk)
        serializer = WidgetSerializer(widget)
        return Response({'serializer': serializer, 'widget': widget})

    def post(self, request, pk=None):
        widget= get_object_or_404(Widget, pk=pk)
        serializer = WidgetSerializer(widget)
        if not serializer.is_valid():
            return Response({'serializer': serializer, 'widget': widget})
        return redirect('widget-list')

这些是通过以下网址进行的 -

urlpatterns = [
    url(r'^widgets/$', views.WidgetList.as_view()),
    url(r'^widgets/(?P<pk>[0-9]+)/$', views.WidgetDetail.as_view()),
]

尝试访问该网址时，我获得了以下追溯 -

Exception Type: NoReverseMatch at /dashboard/
Exception Value: Reverse for 'widget-detail' with arguments '()' and keyword arguments '{u'pk': ''}' not found. 0 pattern(s) tried: []

我知道它失败了，因为它正在寻找一个pk但是我使用这个表格来发帖，因此PK不会存在。我错过了什么？

您需要为您的网址命名：

urlpatterns = [
    url(r'^widgets/$', views.WidgetList.as_view(), name="widget-list"),
    url(r'^widgets/(?P<pk>[0-9]+)/$', views.WidgetDetail.as_view(), name="widget-detail"),
]
