在HTML&此处表单
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>
下面的视图-
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()),
]
当尝试访问URL时，我得到以下回溯-

我知道它失败了，因为它在寻找pk，但我用这个表格发帖，所以pk不会存在。我错过了什么？
您需要命名您的URL：
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"),
]
