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 ConfigurationThe `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.

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：

base.html中{% url ‘home’ %}是出问题的关键所在，结局办法就是在views.py中添加命名空间指定名称为home。
