Django - Receiving error "too many values to unpack (expected 2)"

Question

In my website, I have created a custom user from the AbstractUser class. When I check if a user with the same username or email exists, I get a value error returned to me.

Here's my code: models.py:

class Account(AbstractUser):
    pass

    def __str__(self):
        return self.username

    def __unicode__(self):
        return self.username

views.py:

try:
   user = Account.objects.get(username=request.POST['username'])
   return render(request, 'users/signup.html', {'error': 'Username has already been taken'})
except Account.DoesNotExist:
           try:
               user = Account.objects.get(request.POST['email'])
               return render(request, 'users/signup.html', {'error': 'Email is not available'})
           except Account.DoesNotExist:
                        user = Account.objects.create_user(username=request.POST['username'], email=request.POST['email'], password=request.POST['password']) 
                        auth.login(request, user)
                        return redirect('home')

Error returned:

ValueError at /accounts/signup/
too many values to unpack (expected 2)

Does anybody have a solution? Thank you.

Read this line carefully

File "/Users/eesamunir/Documents/Projects/youtube-project/accounts/views.py" in signup
32.user = Account.objects.get(request.POST['email'])

Error occurs due to this, It should be a key, value pair, Account.objects.get(email=request.POST['email'])
