To meet your initial goal, I do not think the BeforeFilter middle ware is required. What we need is just a template context processor.

Write a context processor as following:

#file: context_processors.py

def sample_context_processor(request):
   return {'ss':'ssssssssss'} #or whatever you want to set to variable ss

then add the context processor to TEMPLATE_CONTEXT_PROCESSORS list

#file: settings.py 

TEMPLATE_CONTEXT_PROCESSORS = (
    'myproject.context_processors.sample_context_processor',
)

You need to specify that you accessing request in the template. If you do just {{ss}} the variable does not exist since it an attribute of request (you did request.ss = 'ssssssssss', right?). So do {{request.ss}} in your template and it should work.

The OP asked for how to do this with middleware but I found this question without needing that requirement. The currently accepted answer is outdated and the edit queue is full.

As of Django 1.10, the TEMPLATE_CONTEXT_PROCESSORS setting has been moved to the context_processors option of TEMPLATES.

context_processors is a list of dotted Python paths to callables that are used to populate the context when a template is rendered with a request. These callables take a request object as their argument and return a dict of items to be merged into the context. It defaults to an empty list.

# context_processors.py

def sample_context_processor(request):
    return {'key': 'value'}

# settings.py

TEMPLATES = [
    {
        'OPTIONS': {
            'context_processors': [
                'myproject.context_processors.sample_context_processor',
            ],
        },
    },
]
