Question

我正在用django编写一个应用程序。一切都工作正常，我一直在应用程序的另一页工作，然后我决定回到主页，我得到了这个错误。

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

一切都很完美，我无法理解为什么。如果我将模板更改为另一个模板让我们说hello.html整个网址响应得很好但是一旦我将其更改回index.html我就会得到同样的错误。任何帮助将不胜感激

form.py

from django import forms
from posts.models import Post

class PostForm(forms.ModelForm):


    class Meta:
        model = Post
        fields = [
            "title",
            "content",
            "image",
            "draft",
            "publish",
        ]

views.py

def index(request):
results = Post.objects.all().filter(draft=False).filter(publish__lte=timezone.now())
que = request.GET.get("q")
if que:
    results =results.filter(
        Q(title__icontains=que)|
        Q(content__icontains=que)).distinct()
paginator = Paginator(results, 8) # Show 25 contacts per page
pages ="page"
page = request.GET.get('page')
try:
    query = paginator.page(page)
except PageNotAnInteger:
    # If page is not an integer, deliver first page.
    query = paginator.page(1)
except EmptyPage:
    # If page is out of range (e.g. 9999), deliver last page of results.
    query = paginator.page(paginator.num_pages)
context = {
    "objects": query,
    "pages": pages
}
template = 'index2.html'
return render(request,template,context)

HTML

    {% extends 'base.html' %}
{% load staticfiles %}
    {% block content %}
    <h1>This is Home</h1>
    {% include 'messages.html'%}
    <form method="GET" action="">
      {% csrf_token %}
      <input type="text" name="q" value="{{ request.GET.q }}" placeholder="search" >
      <input type="submit" name="submit" value="Go!">
    </form>

    {% for obj in objects %}
  <h1>  <a href="{{ obj.get_absolute_url }}">{{ obj.title }}</a></h1><br>
  {% if obj.image %}
  <img src="{{ obj.image.url }}" alt="{{ obj.title }}" width="250" height="250"><br>
  {% endif %}

   {{ obj.content|safe|truncatewords:20 }}
    {{ obj.timestamp }}<br>
    {{ obj.updated }}<br>

    {% endfor %}
    <br>

    <div class="pagination">
    <span class="step-links">
        {% if contacts.has_previous %}

            <a href="?{{ pages }}={{ objects.previous_page_number }}{% if request.GET.q %}&q={{ request.GET.q }}{% endif %}">previous</a>
        {% endif %}

        <span class="current">
            Page {{ objects.number }} of {{ objects.paginator.num_pages }}.
        </span>

        {% if objects.has_next %}
            <a href="?{{ pages }}={{ objects.next_page_number }}{% if request.GET.q %}&q={{ request.GET.q }}{% endif %}">next</a>
        {% endif %}
    </span>
</div>

    {% endblock %}

模型中的绝对网址

def get_absolute_url(self):
        return reverse("more", kwargs={"slug": self.slug})

网址格式

url(r'^$', posts_views.index, name='index'),

rendring模板时django url错误
