NoReverseMatch 错误 Django - UpdateView

Question

我有一个视图，用户可以创建/更新他们的帖子。但是，当用户完成编辑后，我希望他们返回帖子（摘要）。但是，某处有一个我找不到的错误。关于问题可能是什么的任何想法？

错误：1) 未找到带有参数“()”和关键字参数“{'id': 2}”的“aircraftdetail”的反向。尝试了 0 个模式：[]

2) 返回 HttpResponseRedirect(instance.get_absolute_url())

3) return reverse('aircraftdetail', kwargs={"id": self.id})

views.py

def AircraftUpdate(request, id=None):
    instance = get_object_or_404(Aircraft, id=id)
    form = AircraftForm(request.POST or None, instance=instance)
    if form.is_valid():
        instance = form.save(commit=False)
        instance.save()
        return HttpResponseRedirect(instance.get_absolute_url())
    context={"aircraft":instance, "form":form}
    return render(request,'aircraft_form.html',context)

Models.py

class Aircraft(models.Model):
    title = models.CharField(max_length=50, default="")
    image = models.ImageField(upload_to = 'static/image_upload', blank=True)
    cost = models.DecimalField(max_digits=8, decimal_places=3)

def get_absolute_url(self):
        return reverse('aircraftdetail', kwargs={"id": self.id})

Urls.py - 飞机

urlpatterns = [
  url(r'^detail/(?P<id>\d+)/$', views.AircraftDetail, name='AircraftDetail'),
  url(r'^detail/(?P<id>\d+)/edit/$', views.AircraftUpdate, name='AircraftEdit'),
  url(r'^$', views.AircrafList, name='aircraft'),]

Urls.py AviationSite（主）

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'aircraft/', include('aircraft.urls')),
    url(r'^login/', login_view, name="login"),
    url(r'^logout/', logout_view, name="logout"),
    url(r'^register/', register_view, name="register"),
    url(r'^aircraft/create/$', AircraftCreate),]

Answer 1

您的 URL 模式有 `name='AircraftDetail'（大写的 'A' 和 'D'）：

url(r'^detail/(?P<id>\d+)/$', views.AircraftDetail, name='AircraftDetail'),

这与您调用reverse 的aircraftdetail（全部小写）不匹配：

return reverse('aircraftdetail', kwargs={"id": self.id})

更改其中一个以使它们匹配（全小写在 Django 中更常见）。
