Error Message

NoReverseMatch at /well_list/

Reverse for 'contextual' with keyword arguments '{'api': '9933124422'}' not found. 1 pattern(s) tried: ['well_list\\/contextual/$(?P<api>[\\w-]+)/$']

我真的不喜欢这个 . 从我得到 {'api': '9933124422'} 的非空值的事实来看，我认为我正确地从 {% url 'eric_base:contextual' api=well_instance.api %} 注入了字典，但它仍然给我一个错误 . 请帮忙！

    您可以将 TemplateView 更改为 DetailView ，因为 TemplateView 没有 get_object 方法 . 例如在你的情况下：

    class ContextualMainView(TemplateView):
    template_name = 'contextual_main.html'

    至;

    from django.views.generic import DetailView
from django.shortcuts import get_object_or_404

from eric_base.models import WellInfo


class ContextualMainView(DetailView):
    template_name = 'contextual_main.html'
    model = WellInfo

    def get_object(self):
        return get_object_or_404(self.model, api=self.kwargs['api'])

    See also this docs:

    在讨论之后，实际问题就在这里 . 字符 $ 应该用于最终网址，如果您有另一个包含网址，则不应使用该字符 .

    re_path(r'^contextual/$', include('eric_base.urls'))

    至;

    re_path(r'^contextual/', include('eric_base.urls'))
