关于 django:Python: //’module//’ 对象没有属性 //’logout_view//’

Python: ‘module’ object has no attribute ‘logout_view’

我目前正在尝试实现注销到我的 django 站点的功能，但在虚拟环境中尝试使用命令 python manage.py runserver 时出现以下错误：

这是我在 learning_log////users 目录中的 urls.py 文件：

from django.conf.urls import url
from django.contrib.auth.views import login

from . import views

urlpatterns = [
# Login page
url(r‘^login/$’, login, {‘template_name’: ‘users/login.html’},
name=‘login’),
# Logout page
url(r‘^logout/$’, views.logout_view, name=‘logout’),
# Registration page
url(r‘^register/$’, views.register, name=‘register’),
]

对上述文件的最新补充是：

1 2	# Logout page url(r‘^logout/$’, views.logout_view, name=‘logout’),

以下代码作为最新添加添加到了我的 views.py 文件的末尾：

from django.http import HttpResponseRedirect
from django.core.urlresolvers import reverse
from django.contrib.auth import logout

def logout_view(request):
"""Log the user out."""
logout(request)
return HttpResponseRedirect(reverse(‘learning_logs:index’))

这是我的 base.html 文件：

<p><center>[wp_ad_camp_2]</center></p><p>
Learning Log –
Topics –
{% if user.is_authenticated %}
Hello, {{ user.username }}.
log out
{% else %}
log in
{% endif %}
</p>

{% block content %}{% endblock content %}

这是对我的 base.html 文件的最新添加：

log out

在上述添加之前，代码运行良好。知道我这可能很容易解决，但是有人有解决这个问题的方法吗？我目前正在使用 Django 1.11.7 和 Python 2.7.14。

当您在 users//urls.py

中使用相对导入时

1	from . import views

这相当于

1	from users import views

但是，听起来您的 logout_view 在 learning_logs//views.py 中。如果是这种情况，那么您应该将导入更改为

1	from learning_logs import views

请注意，Django 有一个 logout 视图，因此您不必编写自己的视图。将您的导入和 URL 模式更改为：

1
2
3

from django.contrib.auth.views import logout

url(r‘^logout/$’, logout, name=‘logout’),

然后在你的设置中设置 LOGOUT_REDIRECT_URL 以便 Django 在注销用户后重定向到索引：

1	LOGOUT_REDIRECT_URL = ‘learning_logs:index’
