Django Python rest framework, No 'Access-Contr

Question

I have researched and read quite a few Stackoverflow posts on the same issue. None have resolved my issue.

My problem is that I am getting the "...No 'Access-Control-Allow-Origin' header is present on the requested resource..." error in my console.

I am using:

Chrome Version 57.0.2987.133 Firefox Version 52.0.2

Python 2.7 Django 1.11a1

AngularJS

I am using MAMP to serve my front-end Angular stuff, and the django server for the backend stuff.

In my django settings I have included the cors middleware and tried both the whitelist approach and just setting all to true:

MIDDLEWARE = [

    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'corsheaders.middleware.CorsMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',

]

CORS_ORIGIN_ALLOW_ALL = True

On google chrome I still get this error:

localhost/:1 XMLHttpRequest cannot load {my endpoint url}. Redirect from {my endpoint url} to {my endpoint url with a } has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin {requesting url} is therefore not allowed access.

It works appropriately on Firefox, and I can't figure out why it won't work for google chrome. I haven't tried any other types of browsers. Any help will be very appreciated, thank you.

Make sure use 127.0.0.1 NOT localhost because when using localhost browser may look up an IPv6 address... or set up localhost to explicitly to 127.0.0.1 at /etc/hosts
