Django - URLS映射和调度程序的问题

Question

I'm learning Django and I would like to build an application with the calendar and tasks, where every task has a separate link via get_absolute_url . I've created a list of activities and url link to each of them, but when I pick one of them there is no reaction, not even an error message.

Please find my code below.

from django.db import models
from django.utils import timezone
from django.core.urlresolvers import reverse

class PublishedManager(models.Manager):
    def get_queryset(self):
        return super(PublishedManager,self).get_queryset().order_by('hour')

class Activity(models.Model):
    STATUS_CHOICES = (
        ('30 min', '30 min'),
        ('1:00 h', '1:00 h'),
        ('1:30 h', '1:30 h'),
        ('2:00 h', '2:00 h'),
        ('2:30 h', '2:30 h'),
        ('3:00 h', '3:00 h'),
        ('3:30 h', '3:30 h'),
        ('4:00 h', '4:00 h'),
        ('4:30 h', '4:30 h'),
        ('5:00 h', '5:00 h'),
    )
    title = models.CharField(max_length=250)
    slug = models.SlugField(max_length=250, unique_for_date='hour')
    body = models.TextField()
    hour = models.DateTimeField(default=timezone.now())
    created = models.DateTimeField(auto_now_add=True)
    updated = models.DateTimeField(auto_now=True)
    objects = models.Manager()
    duration = models.CharField(max_length=10, choices=STATUS_CHOICES, default='30 min')
    published = PublishedManager()

    class Meta:
        ordering = ('-hour',)

    def __str__(self):
        return self.title

    def get_absolute_url(self):
        return reverse('core_tm:activity_detail',
                       args=[self.slug])


from django.conf.urls import url
from . import views

urlpatterns = [
    url(r'^', views.activity_list, name='activity_list'),
    url(r'^(?P<activity>[-\w]+)/$',
        views.activity_detail, name='activity_detail')


from django.shortcuts import render, get_object_or_404
from .models import Activity

def activity_list(request):
    activities = Activity.published.all()
    return render(request, 'core_tm/activity/list.html', {'activities' : activities})

def activity_detail(request, activity):
    activity = get_object_or_404(Activity, slug=activity)
    return render(request, 'core_tm/activity/detail.html', {'activity' : activity})

List template:

{% extends "core_tm/base.html" %}

{% block title %}<h1>Lista aktywności</h1>{% endblock %}

{% block content %}
    {% for activnes in activities %}
        <h2>
            <a href="{{ activnes.get_absolute_url }}">
                {{ activnes.title }}
            </a>
        </h2>
        <p class="date">
            Data rozpoczęcia : {{ activnes.hour }}
            Czas trwania : {{ activnes.duration }}
        </p>
        {{ activnes.body|truncatewords:30|linebreaks }}
    {% endfor %}

{% endblock %}

Detail template:

{% extends "core_tm/base.html" %}

{% block title %}{{ activity.title }}{% endblock %}

{%block content %}
    <h1>{{ activity.title }}</h1>
    <p class="date">
        Data rozpoczęcia : {{ activity.hour }}
        Czas trwania : {{ activity.duration }}
    </p>
    {{ activity.body|linebreaks }}

{% endblock %}

You need to terminate your activity_list URL:

url(r'^$', views.activity_list, name='activity_list'),

Otherwise this will simply match all paths, including those that are supposed to point to your activities.
