Django 1.4: Why is my context handler not working?

I recently upgraded a project from Django 1.3 to 1.4 and seems to have crashed my context processor.

In myapp/myapp/processors.py:

def currentPath(request):
    return {'current_path': request.get_full_path()}

In myapp/myapp/settings.py:

from django.conf import global_settings

global_settings.TEMPLATE_CONTEXT_PROCESSORS += (
    'myapp.processors.currentPath',
    'django.core.context_processors.request',
)

In any template it {{ current_path }}is expected - and updated the current path before updating. Now it is not processed at all. I am absolutely stuck here.

Just for kicks, don't you think this is the usual way:

- global_settings.TEMPLATE_CONTEXT_PROCESSORS += (
+ 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.contrib.messages.context_processors.messages',
     'myapp.processors.currentPath',
     'django.core.context_processors.request',
 )

This can eliminate your (useful-looking!) Link to global_settingsthe source of the problem.

Secondly, if you run

manage.py shell

does

from myapp.processors import currentPath

? ( , settings.py, context.py , models.py, , , settings.py).

Django 1.8 TEMPLATE_CONTEXT_PROCESSORS .

Deprecated since version 1.8:
Set the 'context_processors' option in the OPTIONS of a DjangoTemplates backend instead.

:

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [
            # insert your TEMPLATE_DIRS here
        ],
        'OPTIONS': {
            'context_processors': [
                # Insert your TEMPLATE_CONTEXT_PROCESSORS here or use this
                # list if you haven't customized them:
                'django.contrib.auth.context_processors.auth',
                'django.template.context_processors.debug',
                'django.template.context_processors.i18n',
                'django.template.context_processors.media',
                'django.template.context_processors.static',
                'django.template.context_processors.tz',
                'django.contrib.messages.context_processors.messages',
            ],
            'loaders': [
                # insert your TEMPLATE_LOADERS here
            ]
        },
    },
]

You should return a dict:

def currentPath(request):
    return {'current_path': request.get_full_path()}

You need to enable RequestContextcontext for processors to process.

You can use a rendershortcut to enable it automatically:

from django.shortcuts import render

def my_view(request):
   context = {}
   return render(request, 'mytemplate.html', context)

If you use classic views, it RequestContextwill be turned on automatically.
