Question

模板

<form action="" method="post">{% csrf_token %}
    {{ form.as_p }}
    <input type="submit" value="Update" name="_save" />
</form>

形式

class LabelUpdateForm(forms.ModelForm):

    def clean(self):
        return self.cleaned_data

    class Meta:
        model = models.SlPannelli
        fields = '__all__'

查看

class LabelUpdateView(UpdateView):
    model = models.SlPannelli
    exclude=()
    fields = '__all__'
#    form_class = LabelUpdateForm  

    def form_valid(self, form):
        return super(LabelUpdateView, self).form_valid(form)
        return TemplateResponse(self.request, self.template_name, locals())

网址

url(r'^labelch/(?P<pk>\d+)$', views.LabelUpdateView.as_view(), name='label_update'),

我可以看到加载的数据用于更新，但是当点击更新按钮时，不断重定向到＆＃34; labelch /＆＃34;页面，无法保存更新的数据。

[解决]

url(r'^(?P<pk>\d+)/labelch$', views.LabelUpdateView.as_view(), name='label_update'),

无法理解为什么但是在URL中更改pk的顺序解决了所有问题！

@simone感谢您的建议，将来会记住！
