'is_authenticated'仍然总是在模板中返回false [英] 'is_authenticated' still always returns false in template

问题描述

以下是我的其他问题，因为它可能需要不同的答案。

我的模板中的代码总是返回false：

  {％if request.user.is_authenticated％} 
< p>我登录了< / p> 
 {％else％} 
< p>我是匿名的< / p> 
 {％endif％} 
  

我从文档中了解到，我需要包括django .contrib.auth.context_processors.auth在settings.py中的 TEMPLATE_CONTEXT_PROCESSORS 中，所以我已经这样做了，如下所示：

  TEMPLATE_CONTEXT_PROCESSORS =（
django.contrib.auth.context_processors.auth，
django.core.context_processors.debug，
django。 core.context_processors.i18n，
django.core.context_processors.media，
django.core.context_processors.static，
django.core.context_processors.tz，
django.contrib.messages.context_processors.messages，
django.contrib.auth.context_processors.auth，#Added 
）
  / pre> 
 
 
对于我的views.py，我使用 render_to_response（），但感觉这可能是导致问题。我还需要在上下文中从数据库传递一个用户，但添加了第三个参数 context_instance = RequestContext（request） 
  def public_profile（request，username_in_url）：
 user = User.objects.get（username = username_in_url）
 context = {
'user '：user，
} 
 
 return render_to_response（'public_profile.html'，context，context_instance = RequestContext（request））
  
为什么 request.user.is_authenticated 仍然返回false，即使用户登录？在views.py中使用相同的方法正常工作 。 
 
 
 如果request.user.is_authenticated（）：
返回render_to_response（'public_profile.html'，上下文）
 else：
 return render_to_response（'public_profile_anon.html'，context）
  
 
 
解决方案
  django.contrib.auth.context_processors.auth 说，这个上下文处理器定义了两个变量： user 和 perms 。而用户是
 
 
一个 auth.User 实例，表示当前登录的用户（或$ code> AnonymousUser 实例，如果客户端未登录）。
 
 
所以尽管在您的Python代码中，您可以访问 request.user 来执行检查，在模板中用户。 
 
 
 
您的具体案例的问题是您还会传递一个基于<$ code> user 的字典C $ C> username_in_url 。这与由 django.contrib.auth.context_processors.auth 定义的变量冲突。 
 
 
 
所以：
 
 
 
更改字典（你命名为 context ），以便用户具有不同的名称。 （并更改您的模板中的引用。）
 
 
 
 
更改模板以检查 {％if user.is_authenticated％} 。
 
 
 
 
This is following on from my other question, as it will likely require a different answer.


The code in my template is always returning false:
   {% if request.user.is_authenticated %}
      <p>I'm logged in</p>
   {% else %}
      <p>I am anonymous</p>
   {% endif %}
I understand from the docs that I need to include "django.contrib.auth.context_processors.auth" within TEMPLATE_CONTEXT_PROCESSORS in settings.py so I have done so as follows:
TEMPLATE_CONTEXT_PROCESSORS = (
    "django.contrib.auth.context_processors.auth",
    "django.core.context_processors.debug",
    "django.core.context_processors.i18n",
    "django.core.context_processors.media",
    "django.core.context_processors.static",
    "django.core.context_processors.tz",
    "django.contrib.messages.context_processors.messages",
    "django.contrib.auth.context_processors.auth", #Added
)
As for my views.py, I am using the render_to_response() but feel this may be causing the issue. I also need to pass a user from the database within the context, but have added the third parameter context_instance=RequestContext(request)
def public_profile(request, username_in_url):
    user = User.objects.get(username = username_in_url)
    context = {
        'user': user,       
    }

    return render_to_response('public_profile.html', context, context_instance=RequestContext(request))
Why does request.user.is_authenticated still return false even though a user is logged in? Using the same method within views.py works correctly e.g. 
if request.user.is_authenticated():
        return render_to_response('public_profile.html', context)
    else:
        return render_to_response('public_profile_anon.html', context)

解决方案
The documentation for django.contrib.auth.context_processors.auth says that this context processor defines two variables: user and perms. And user is

  
An auth.User instance representing the currently logged-in user (or an AnonymousUser instance, if the client isn’t logged in).
So although in your Python code you would access request.user to perform your check, in the template it is user. 

The problem with your specific case is that you also pass a dictionary that defines user on the basis of username_in_url. This clashes with the variable defined by django.contrib.auth.context_processors.auth. 

So:

Change the dictionary (which you named context) so that user has a different name. (And change references to it in your template.)
Change your template to check {% if user.is_authenticated %}.
