尝试启动服务器并出现错误行,如
NoReverseMatch at /polls/
Reverse for 'detail' with arguments '(1,)' not found. 1 pattern(s) tried: ['polls/<int:pk>/']
我的views.py
class IndexView(generic.ListView):
template_name = 'polls/index.html'
context_object_name = 'latest_question_list'
def get_queryset(self):
"""Return the last five published questions."""
return Question.objects.order_by('-pub_date')[:5]
class DetailView(generic.DetailView):
model = Question
template_name = 'polls/detail.html'
class ResultsView(generic.DetailView):
model = Question
template_name = 'polls/results.html'
查看索引,结果和详细信息
我的urls.py
from django.conf.urls import url
from . import views
app_name = 'polls'
urlpatterns = [
url('', views.IndexView.as_view(), name='index'),
url(r'^<int:pk>/', views.DetailView.as_view(),name='detail'),
url(r'^<int:pk>/results/', views.ResultsView.as_view(), name='results'),
url(r'^<int:question_id>/vote/', views.vote, name='vote'),
]
我的index.html
{% if latest_question_list %}
<ul>
{% for question in latest_question_list %}
<li><a href="{% url 'polls:detail' question.id %}">{{ question.question_text }}</a></li>
{% endfor %}
</ul>
{% else %}
<p>No polls are available.</p>
{% endif %}
我已经尝试了很多次,但是我没有解决方案,请帮帮我。

您正在混用url()
语法(使用正则表达式)和Django 2.0+中新的path()
语法。
确保您使用的教程与Django版本相匹配(例如Django 2.1或Django 1.11),然后确保urls.py与教程中的代码完全匹配。

对于使用正则表达式的人,下面的类似内容将起作用;
function groupArray(arr) {
const map = {};
arr.forEach(element => {
const [id, type, code, priority] = element;
map[code] = Array.isArray(map[code]) ? [...map[code], element] : [element];
});
return map;
}
const type_zero_group = groupArray(type_zero)
const type_one_group = groupArray(type_one)
const type_two_group = groupArray(type_two)
