django - 没有反向匹配的登录视图 [英] django - no reverse match for login view

问题描述

基本上我想看看用户登录表单页面，但我得到：

 渲染时捕获NoReverseMatch：反转为''django.contrib.auth.views.login'与参数'（）'和关键字参数'{}'未找到。 
  

我的urls.py文件：

  from django.conf.urls.defaults import patterns，include，url 
 
 urlpatterns = patterns（''，
 url（r'^ accounts / login / $'，'django.contrib.auth.views.login'），
）
  

我的settings.py（INSTALLED_APPS）

  INSTALLED_APPS =（
'django.contrib.auth'，
'django.contrib.contenttypes'，
'django.contrib.sessions'，
'django.contrib.sites'，
'django.contrib.messages'，
' django.contrib.staticfiles'，
）

<编辑：我意识到我在看错了事情。错误发生在模板文件中：

  {％if form.errors％} 
< p>您的用户名和密码不匹配。请再试一次。< / p> 
 {％endif％} 
 
< form method =postaction ={％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 =submitvalue =login/> 
< input type =hiddenname =nextvalue ={{next}}/> 
< / form> 
  

专门针对这一行：

 < form method =postaction ={％url'django.contrib.auth.views.login'％}> 
  

解决方案

尝试这个：

  url（r'^ accounts / login $'，'django.contrib.auth.views.login'），
  

编辑后：

  form method =postaction ={％url django.contrib.auth.views.login％}> 
  

编辑
在设置。 py django文件，此行：

APPEND_SLASH = False

告诉您的反向网址是否以斜线完成。然后

  APPEND_SLASH = True 
 url（r'^ accounts / login /'，'django.contrib.auth。 views.login'）
  

应该也可以。

I am just trying out django and following the documentation for authentication.

Basically I want to take a look at the user login form page, but I am getting:

Caught NoReverseMatch while rendering: Reverse for ''django.contrib.auth.views.login'' with arguments '()' and keyword arguments '{}' not found.

My urls.py file:

from django.conf.urls.defaults import patterns, include, url

urlpatterns = patterns('',
    url(r'^accounts/login/$', 'django.contrib.auth.views.login'),
)

My settings.py (INSTALLED_APPS)

INSTALLED_APPS = (
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.sites',
'django.contrib.messages',
'django.contrib.staticfiles',
)

EDIT: I realized I was looking at the wrong thing. The error occurs in the template file:

{% 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>

Specifically for the line:

<form method="post" action="{% url 'django.contrib.auth.views.login' %}">

解决方案

Try this:

url(r'^accounts/login$', 'django.contrib.auth.views.login'),

And after your edit:

<form method="post" action="{% url django.contrib.auth.views.login %}">

EDIT in settings.py file of django, this line:

APPEND_SLASH = False

tells whether your reverse url finish with slash or not. Then

APPEND_SLASH = True
url(r'^accounts/login/', 'django.contrib.auth.views.login')

should work as well.
