Question

当我尝试进入asset_list视图时，它挂在Option Explicit Sub numberfiller() Dim i As Long Dim maxrow As Long i = 2 maxrow = 100 With ThisWorkbook.Worksheets(1) While Not IsEmpty(.Range("A" & i).Value) And i < maxrow If Not .Range("A" & i).Value = .Range("A" & i - 1).Value + 1 Then .Range("A" & i).EntireRow.Insert shift:=xlDown .Range("A" & i).Value = .Range("A" & i - 1).Value + 1 Else i = i + 1 End If Wend End With End Sub上并抛出错误

get_absolute_url()

我正在网站上使用一堆此资产应用程序的实例，每个实例将基于标签属性提供一些不同的资产。 Apphooks运作良好，所有内容都附在cms中。在开始尝试细节视图之前，我已完成所有工作。我认为我有两个问题，一个是Reverse for 'asset_detail' with keyword arguments '{'id': 1}' not found. 1 pattern(s) tried: ['en/marketing/$/<int:id>/']，另一个是get_absolute_url

这就是我所拥有的

urls.py

urls.py

models.py

from django.conf.urls import url, include
from .views import AssetListView, AssetDetailView

app_name = 'assets'
urlpatterns = [
    # List View
    url(r'^$', AssetListView, name="asset_list"),
    url(r'^$/<int:id>/', AssetDetailView, name='asset_detail')

]

views.py

class Asset(models.Model):
    name = models.CharField(max_length=50, blank=False)
    description = PlaceholderField('asset_description')
    asset_category = models.ManyToManyField(Asset_Category, blank=True)
    tag = models.ManyToManyField(Tag, blank=True)
    product_category = models.ManyToManyField(Category, blank=True)
    product_series = models.ManyToManyField(Series, blank=True)
    product_line = models.ManyToManyField(Line, blank=True)

    url = models.CharField(max_length=250, blank=True, verbose_name='Video URL')
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)
    is_active = models.BooleanField(default=True)


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

asset_view.html

def AssetListView(request, *args, **kwargs):
    path = os.path.basename(os.path.normpath(request.path))
    print(path)

    page_obj = Title.objects.filter(slug=path).first()
    print (page_obj)

    for obj in Tag.objects.all():
        print (obj.name)
        if obj.name == page_obj.title:
            queryset = Asset.objects.filter(tag=obj.id)
            context = {
                'object_list': queryset,
            }
            return render(request, 'asset_view.html', context)  

    queryset = Asset.objects.all()

    context = {
        'object_list': queryset,
    }
    return render(request, 'asset_view.html', context)



def AssetDetailView(request, *args, **kwargs):
    return HttpResponse('<h1>AssetDetailView<h1>')

Answer 1

URL无效，您不能在此处插入$锚点，因为$表示字符串的 end 。此外，由于您使用url(..)，因此它应该是正则表达式，例如：

url(r'^(?P\d+)/$', AssetDetailView, name='asset_detail')

请注意，PEP-8建议以小写形式编写函数名称，并在单词之间使用下划线。因此，我建议将函数重命名为asset_detail_view和asset_list_view。

ReverseNotFound-无法将详细信息视图连接到列表视图
