from django.conf.urls import url 

from .views import blog_postListView, blog_postDetailView, blog_postCreateView 

urlpatterns = [ 

    url(r'^$', blog_postListView.as_view(), name='blog_post_list'),

基本HTML中，导航部分

<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1"> 
     <ul class="nav navbar-nav"> 
       <li> 
       <a href="/">Home</a> 
      </li> 
      <li> 
       <a href="{% url 'about' %}">About</a> 
      </li> 
      <li> 
       <a href="{% url 'contact' %}">Contact</a> 
      </li> 
      <li> 
       <a href="/blog">Blog</a> 
      </li> 
      <li> 
      {% if request.user.is_authenticated %} 
        <li><a href="{% url 'auth_logout' %}">Logout</a></li> 
       {% else %}

Answer 1

把下面一行在结束url_patterns列表像

urlpatterns = [ 
    #all other urls, 
    url(r'', include('blog.urls')), 
] 

OR

url(r'^blogdetail/', include('blog.urls')),
