Answer 1

I think you must have to share upper part of your view for more clarification.

But you can try this:

return render(request, template, {'context':context})

Answer 2

Must be either a client-side caching or Nginx caching ;)

(1) in the first case, the browser in not requesting an updated resource because it has been told that the previous resource is still valid;

To confirm this, try using Chrome in incognito and see what happens.

If this is the case, I would add the "never_cache" decorator to the Django views:

from django.views.decorators.cache import never_cache

class MyView(View):

    @never_cache
    def dispatch(self,request,*args,**kwargs):
        return super().dispatch(request,*args,**kwargs)

or, in a function based view:

@never_cache
def myview(request, ...):
   ...

Using the "never_cache" decorator, you instruct the browser not to cache the page, so whenever the user requires it, he's browser will in turn hit the server.

(2) if not, must be Nginx; check all nginx config files:

• /etc/nginx/nginx.conf
• /etc/nginx/sites-available/*.conf

and comment out any parameter containing "cache", then restart the service.

I would also turn off "sendfile" as suggested here: https://jeremyfelt.com/2013/01/08/clear-nginx-cache-in-vagrant/

by adjusting file /etc/nginx/nginx.conf as follows:

...
html {
    ...
    sendfile off;
    ...
