在用django搭建博客时由于配置url.py文件错误出现如下异常：

Reverse for 'home' with arguments '()' and keyword arguments '{}' not found. 0 pattern(s) tried: []

初始url.py配置如下：

"""my_blog URL Configuration

The `urlpatterns` list routes URLs to views. For more information please see:
    https://docs.djangoproject.com/en/1.9/topics/http/urls/
Examples:
Function views
    1. Add an import:  from my_app import views
    2. Add a URL to urlpatterns:  url(r'^$', views.home, name='home')
Class-based views
    1. Add an import:  from other_app.views import Home
    2. Add a URL to urlpatterns:  url(r'^$', Home.as_view(), name='home')
Including another URLconf
    1. Import the include() function: from django.conf.urls import url, include
    2. Add a URL to urlpatterns:  url(r'^blog/', include('blog.urls'))
"""
from django.conf.urls import url
from django.contrib import admin
from article.views import home
urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^$', home),
    url(r'^(?P<id>\d+)/$','article.views.detail',name='detail'),
]

    url(r'^$', home,name='home'),#指定命名空间为’home'
    url(r'^(?P<id>\d+)/$','article.views.detail',name='detail'),
]

问题解决。
home.html文件如下：

<!--home.html-->
{% extends "base.html" %}

{% block content %}
<div class="posts">
    {% for post in post_list %}
        <section class="post">
            <header class="post-header">
                <h2 class="post-title"><a href="{% url 'detail' id=post.id %}">{{ post.title }}</a></h2>

                    <p class="post-meta">
                        Time:  <a class="post-author" href="#">{{ post.date_time |date:'Y /m /d'}}</a> <a class="post-category post-category-js" href="#">{{ post.category }}</a>
                    </p>
            </header>

                <div class="post-description">
                    <p>
                        {{ post.content }}
                    </p>
                </div>
                <a class="pure-button" href="{% url 'detail' id=post.id %}">Read More >>> </a>
        </section>
    {% endfor %}
</div><!-- /.blog-post -->
{% endblock %}

base.html如下：
