How to customize the user model?

Question

Django

Hello Toaster.
Judging by the documentation, you can make custom user registration.
https://docs.djangoproject.com/en/1.8/topics/auth/...
But, is it possible to completely write your own and generally remove the extra tables that django creates in the database? (a habit after Flask)
If not, then how can I store users in my table (own model) and, when registering, put there the specific data I need. I'm not interested in user groups / date and time of the last login and so on.
Z.Y. Developments:
forms.py

class RegistrationForm(forms.ModelForm):
  """
  Form for creating new user
  """
  name = forms.CharField(widget = forms.TextInput(attrs={'placeholder': 'Name'}))
  surname = forms.CharField(widget = forms.TextInput, label = "Surname")
  login = forms.CharField(widget = forms.TextInput, label = "Username")
  email = forms.EmailField(widget = forms.TextInput, label = "E-mail")
  pswd = forms.CharField(widget = forms.PasswordInput, label = "Password")
  pswd_check = forms.CharField(widget = forms.PasswordInput, label = "Repeat password")

views.py

def register(request):
  form = RegistrationForm()
  if request.method == 'POST':
    if form.is_valid():
      RegistrationForm.save()
  return render_to_response('details.html', {'form': form}, RequestContext(request))

urls.py

urlpatterns = [
  url(r'^admin/', include(admin.site.urls)),
  url(r'^register/', register),
]

details.html

<form action ="" method="POST">
  {% csrf_token %}
  Name: {{ form.name }} <br><br>
  Surname: {{ form.surname }} <br><br>
  Login: {{ form.login }} <br><br>
  Pass: {{ form.pswd }} <br><br>
  Check pass: {{ form.pswd_check }} <br><br>
  <button type="submit">Reg</button>
</form>

How now I should save the user in the table in a DB?

Answer 1

But, is it possible to completely write your own and generally remove the extra tables that django creates in the database? (habit after Flask)

Of course you can, from INSTALLED_APPS you throw out this:

'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',

And your database will be dry and comfortable :), and then write everything you need yourself.

Maybe this will work:
