Custom Django login form middleware - django

Question

I'm looking at a solution of implementing a modal pop-up login form to be used site wide in the navigation bar. I'm working with Django 1.11. Now, I'm defining a LoginFormMiddleware class as follows:
middleware.py
from django.http import HttpResponseRedirect
from django.contrib.auth import login
from django.contrib.auth.forms import AuthenticationForm
class LoginFormMiddleware(object):
def __init__(self, get_response):
self.get_response = get_response
def __call__(self, request):
return self.get_response(request)
def process_request(self, request):
from django.contrib.auth.forms import AuthenticationForm
if request.method == 'POST' and request.POST.has_key('base-account') and request.POST['base-account'] == 'Login':
form = AuthenticationForm(data=request.POST, prefix="login")
if form.is_valid():
from django.contrib.auth import login
login(request, form.get_user())
request.method = 'GET'
else:
form = AuthenticationForm(request, prefix="login")
request.login_form = form
This is all included in the standard way in settings.py in MIDDLEWARE = []. I also have 'django.template.context_processors.request' defined in TEMPLATES = [ { ... 'OPTIONS': { 'context_processors': [ *** ] } ] as I should.
Using {{ request.login_form }} in my templates as follows:
<div class="container">
{{ request.login_form }}
</div>
Yet nothing is being rendered - where it should? From browser inspector tools:
Can anyone advise me on what I am missing please?
Full middleware list:
MIDDLEWARE = [
'django.middleware.security.SecurityMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.common.CommonMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',
'wagtail.wagtailcore.middleware.SiteMiddleware',
'wagtail.wagtailredirects.middleware.RedirectMiddleware',
'thinkingplace.middleware.LoginFormMiddleware',
]

process_request is from the old-style, pre-Django 1.10 middleware. You are using new-style middleware so Django will not call that method.
You could move that code to the __call__ method before you call get_response.
def __call__(self, request):
# code that sets request.login_form
return self.get_response(request)
However, I’m not sure that using a middleware is the best approach here. I would consider creating a context processor that adds the login form to the template context, then submit login requests to a single login view.
