def index(request):

    return render(request,'index.html',{'features': features})

#=-------register function-------

def register(request):

    if request.method == 'POST':

        username = request.POST.get('username')

        email = request.POST.get('email')

        password = request.POST.get('password')

            auth.login(request, user)

            return redirect('/')

        else:

            return redirect('login')

    else:

You have this statement:

    user = User.objects.create_user(username=username, email=email, password = password)

Just before this statement, you need to insert a statement that will enable you to examine the value of the "username" statement. Something like this:

    print(username)

    user = User.objects.create_user(username=username, email=email, password = password)

This might or not might work properly with Django. What most Python programmers would do instead is this:

    import pdb; pdb.set_trace()

    user = User.objects.create_user(username=username, email=email, password = password)

but for that you need to know how to use pdb. It's quite simple though tricky at first. Eventually you will need to learn it, however, so now would be a good time. Search the web.

Hi Raj,

Error is showing due to the blank value in user name, please try to print username before registration if it's blank please check form fields. 

Once done you can directly login your account with 

"auth.login(request,user)

Hi, 

Thanks for the response, I have tried to print the username before creating the user, but it did not work. I have also tried to use pdb that also didn't work.

How to do it can give proper instructions??

I have searched about it on google but have not received any relevant answer.
