Django Accessing Session Variable from within Context_Processor function -

i setting session variable inside view as:

def festival_theme(request, year, month, day, slug):     festival = project.objects.get(category__name=__('festival'), slug=slug)      request.session['_active_festival_id'] = festival.id      return render(request, 'web/festival/theme.html', {'festival':festival,}) 

than inside context processor function want session variable's value. how can achieve this?

i have tried:

#context_processors.py def festivals(request):     s = sessionstore()     activefestivalid = s['_active_festival_id']     allfestivals = project.objects.filter(category__name='festival').order_by('-date')     return {'allfestivals':allfestivals} 

you should able access session using request.session in context processor.

#context_processors.py def festivals(request):     activefestivalid = request.session.get('_active_festival_id', none)     allfestivals = project.objects.filter(         category__name='festival').order_by('-date')     return {'allfestivals': allfestivals}
