django中的登录与退出

django中的登录退出开发，也是非常的简单，简单的配置，简单的继承，即可达到完美。
settings.py中：

LOGIN_URL = '/login/'
LOGIN_REDIRECT_URL = '/frontend/'
LOGOUT_URL = '/logout/'

urls.py中：

url(r'^login/$', 'django.contrib.auth.views.login', {'template_name': 'login.html'}),
url(r'logout/$', 'django.contrib.auth.views.logout_then_login'),

login.html中:

{% load url from future %}

{% block content %}

{% if form.errors %}
<p>Your username and password didn't match. Please try again.</p>
{% endif %}

<form method="post" action="{% url 'django.contrib.auth.views.login' %}">
{% csrf_token %}
<table>
<tr>
<td>{{ form.username.label_tag }}</td>
<td>{{ form.username }}</td>
</tr>
<tr>
<td>{{ form.password.label_tag }}</td>
<td>{{ form.password }}</td>
</tr>
</table>

<input type="submit" value="login" />
<input type="hidden" name="next" value="{{ next }}" />
</form>

{% endblock %}
