Django-视图中的上下文处理器？

Question

Context processors in Django usually allow for a variable to be accessed by all templates. How do I access this variable in the views.py (backend) code?

Here is what I have tried:

def index(request):
    request_context = RequestContext(request)
    center =  request_context.get("center")

But I get "none" for the center variable.

And in the context processor code:

def center(request):
return {'center': '123'}

I have added the context processor's "center" function to the context processor list in settings.

Use decorators instead of context_processors . It will be really very simple for you. In views.py use @csrf_exempt before function from which you want to take a variable and use {% csrf_token %} on the end of a line in the template where you want to use that variable.
Official documentation on csrf decorators

If you need to see an example then check out this . Here in template/add_comment.html and views.py is using decorators.

NOTE :- you need to import csrf_exempt in views.py before using it like:-
from django.views.decorators.csrf import csrf_exempt
