在Django注销内置视图中添加extra_context [英] Adding extra_context in Django logout built-in view

问题描述

在 django / contrib / auth / views.py 有注销视图的定义：

In django/contrib/auth/views.py there is the definition of the logout view :

def logout(request, next_page=None,
       template_name='registration/logged_out.html',
       redirect_field_name=REDIRECT_FIELD_NAME,
       current_app=None, extra_context=None):

我想添加extra_context以摆脱我注销时出现的登出标题

I would like to add extra_context to get rid of the 'Logged out' title that appear when I log off

所以我试图在我的url confs：

so I'm trying this in my url confs :

(r'^accounts/logout/$', logout(extra_context={'title':'something else'}) ),

但是我得到这个错误：logout（）至少需要1个非关键字参数（0给定）
我做错了什么？
ps：
当我做

but then I get this error : logout() takes at least 1 non-keyword argument (0 given) what I'm doing wrong? ps: when I do

(r'^accounts/logout/$', logout ),

它可以工作，但后来我收到了注销文本...

it works, but then I get the 'Logged out' text...

谢谢，
Fred

Thanks, Fred

推荐答案

当你写 logout（extra_context = {'title'：'something else'}），你实际上是在URLconf中调用 logout 这不行。 任何URLconf元组都可以有一个可选的第三个元素，其中应该是一个额外的关键字参数的字典传递给视图功能。

When you write logout(extra_context={'title':'something else'}), you're actually calling logout right there in the URLconf, which won't work. Any URLconf tuple can have an optional third element, which should be a dictionary of extra keyword arguments to pass to the view function.

(r'^accounts/logout/$', logout, {'extra_context':{'title':'something else'}}),

或者，您可以编写自己的视图，调用注销传入你想要的任何参数 - 这通常是在更复杂的情况下扩展基于功能的通用视图。

Alternatively, you could write your own view which calls logout passing in whatever arguments you want -- that's typically how you would "extend" function-based generic views in more complicated cases.
