title: Django AbstractUsers create_user not working properly
body: <p>I have my models defined as:</p>
  
  <pre><code>class MyUser(AbstractUser):
      created = models.DateTimeField(auto_now_add=True)
      name = models.CharField(max_length=256)
      phone = models.IntegerField()
  
      USERNAME_FIELD = 'email'
      REQUIRED_FIELDS = ['username', 'name', 'phone']
  
  MyUser._meta.get_field_by_name('email')[0]._unique=True
  </code></pre>
  
  <p>now when I am calling create_user by sending all the arguments in the form
  my view.py looks like</p>
  
  <pre><code>def new_user(request):
      email = request.POST.get('email','')
      phone = request.POST.get('phone','')
      name = request.POST.get('name','')
      password = request.POST.get('password','')
      confirm_pass = request.POST.get('confirm_password','')
      if password and confirm_pass and password == confirm_pass:
          try:
              user = MyUser.objects.get(email=email)
          except MyUser.DoesNotExist:
              user = None
          if user:
              message = 'User with the following email id already exists'
              return render(request, 'signup.html', {'message':message})
          else:
              user = My.objects.create_user(email, email, name, phone, password)
              user.save()
              login(request, user)
              return render(request, 'details.html', {'username':request.user.username})
      else:
          message = 'Paaswords does not match each other'
      return render(request, 'signup.html', {'message':message})
  </code></pre>
  
  <p>Now each time this function executes it shows me the following error</p>
  
  <blockquote>
    <p>create_user() takes at most 4 arguments (6 given)</p>
  </blockquote>
  
  <p>I could'nt understand why is create_user not working.</p>
