Django管理者にログインした後でKeyErrorがスローされました

Question

Django管理者にログインした後、かなり厄介なKeyErrorが発生しました。キー "user"を見つけることができません。それが役に立ったら、私は "User"というモデルを持っています。

これを修正するにはどうすればよいですか？私の設定に何か問題がありますか？私はDjango tutorialsに記載されているデフォルトの管理設定を使用しています。ここで

私のsettings.pyの一部である：あなたのTEMPLATE_CONTEXT_PROCESSORSにこれを追加すること

Answer 1

試してみてください。

django.contrib.auth.context_processors.auth

これは、テンプレートに利用できるuserオブジェクトを経由せRequestContext：https://docs.djangoproject.com/en/dev/ref/templates/api/#django-contrib-auth-context-processors-auth

Answer 2

Django 1.8以上：TEMPLATE_CONTEXT_PROCESSORShas been deprecated新しい「複数テンプレートバックエンド」の作業着陸のため。新しいTEMPLATES設定を使用している場合は、代わりに使用する必要があるエンジンでコンテキストプロセッサを設定する必要があります。この例では、それはそうのようにそれを設定することを意味：

TEMPLATES = [ 
    { 
     'BACKEND': 'django.template.backends.django.DjangoTemplates', 
     'OPTIONS': { 
      'context_processors': [ 
       'django.contrib.auth.context_processors.auth', 
       '..etc..' 
      ], 
     }, 
    }, 
] 

私はわざとそれをより明確にするためにエンジンのdictで利用可能な他のオプションをオフに残っています。
