python - Django template can't loop defaultdict - Stack Overflow
December 29, 2021 at 11:19:35 AM GMT+1 - permalink -django template does not like defaultdict, 2 solutions:
1) set default_factory to None
or
2) cast defaultdict to a simpledict"The template variable resolution algorithm in Django will attempt to resolve new_data.items as new_data['items'] first, which resolves to an empty list when using defaultdict(list)."

Django ALLOWED_HOSTS for Amazon ELB - Stack Overflow
June 10, 2020 at 4:54:02 PM GMT+2 - permalink -Another simple solution would be to write a custom MIDDLEWARE which will give the response to ELB before the ALLOWED_HOSTS is checked. So now you don't have to load ALLOWED_HOSTS dynamically.
The middleware can be as simple as:
project/app/middleware.py
from django.http import HttpResponse
from django.utils.deprecation import MiddlewareMixinclass HealthCheckMiddleware(MiddlewareMixin):
def process_request(self, request):
if request.META["PATH_INFO"] == "/ping/":
return HttpResponse("pong")settings.py
MIDDLEWARE = [
'corsheaders.middleware.CorsMiddleware',
'app.middleware.HealthCheckMiddleware',
'django.middleware.security.SecurityMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.common.CommonMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
...
