About Caching Only Anonymous Visits
To make sure that user navigation or widgets are not cached and shown for other users, it's important to cache only anonymous visits.
You can do that with this decorator:
# myproject/apps/utils/caching.py
from django.views.decorators.cache import cache_page
def cache_page_for_anonymous(timeout, **kwargs):
def decorator(view_func):
cached_view = cache_page(timeout, **kwargs)(view_func)
@wraps(view_func)
def wrapper(request, *args, **kw):
if request.user.is_authenticated:
return view_func(request, *args, **kw)
return cached_view(request, *args, **kw)
return wrapper
return decorator
Then cache the view as follows:
from django.shortcuts import render, get_object_or_404
from django.contrib.auth.models import User
from myproject.apps.utils.caching import cache_page_for_anonymous
@cache_page_for_anonymous(60 * 15) # Cache the view for 15 minutes
def user_profile_view(request, username):
user = get_object_or_404(User, username=username)
context = {
"user": user,
}
return render(request, "pages/user_profile.html", context)
