authenticate() got an unexpected keyword argument 'username'

I am having a strange error in django while trying to authenticate my user.

here is the code:

views.py

from django.shortcuts import render_to_response
from django.http import HttpResponseRedirect
from django.template import RequestContext
from django.core.context_processors import csrf
from django.contrib.auth.forms import AuthenticationForm
from django.contrib.auth import authenticate, login

def authenticate(request):
    username = request.POST['username']
    password = request.POST['password']
    user = authenticate(username=username, password=password)
    if user is not None:
        if user.is_active:
            login(request, user)
            # Redirect to a success page.
        else:
            pass
            # Return a 'disabled account' error message
    else:
        pass
        # Return an 'invalid login' error message.

It keeps giving me this error:

Environment:

The code is using authenticate as a view name. That overwrites the reference to the imported function authenticate.

from django.contrib.auth import authenticate, login
#                               ^^^^^^^^^^^^

def authenticate(request):
#   ^^^^^^^^^^^^

Rename the view:

def other_view_name(request):

Or import the function as different name (also change call to the function):

from django.contrib.auth import authenticate as auth
...

user = authenticate(...) -> user = auth(...)

Or import django.contrib.auth and use the fully qualified name.

import django.contrib.auth
...

user = authenticate(...) -> user = django.contrib.auth.authenticate(...)
