如何在django中注销？

Question

html code

{% if request.user %}
    <a href="{% url 'main:logout' %}">
        Выход
    </a>
{% else %}
    <a href="{% url 'main:registration' %}">
        Регистрация
    </a>
{% endif%}    

settings.py

LOGIN_REDIRECT_URL = 'main/index'

views.py

def logout(request):
    logout(request)

urls.py

from django.conf.urls import url
from . import views
from django.conf import settings

urlpatterns = [
    url(r'^logout/$', views.logout, {'next_page': settings.LOGOUT_REDIRECT_URL}, name='logout')
]

what's wrong?

Answer 1

Django 2.0 it looks like it switched to a class based view

from django.contrib.auth.views import LogoutView

url(r'^logout/$', LogoutView.as_view(), {'next_page': settings.LOGOUT_REDIRECT_URL}, name='logout'),

Answer 2

You are using your custom logout view which doesn't take next_page parameter. You should add it as parameter to your view and pass to django logout call, or just use django.contrib.auth.logout

eg in urls.py:

from django.conf.urls import url
from django.conf import settings
from django.contrib.auth.views import logout

urlpatterns = [
    url(r'^logout/$', logout, {'next_page': settings.LOGOUT_REDIRECT_URL}, name='logout')
]

Answer 3

首先导入django logout，只需在视图文件顶部的from django.contrib.auth import logout中写入

Answer 4

For me, the url 'logout' was being used elsewhere, despite Django loudly complaining if I removed the 'logout' url from urls.py (I am using Django 1.11). I have no idea why/where/how. My hacky working solution was to use a different url, 'signout':

    url(r'^signout/$', logout, {'next_page': settings.LOGOUT_REDIRECT_URL}, name='logout'),
