reg:not able to open registration form web page

Hello Members, 

I am new to Django, and trying to create a mock Django registration page. I am using default Django "User" model to do that, and I am not customizing anything. Its a very simple form with 3 fields as follows:

'username','password','email'. Below are my python and html code details:

form.py

-------

from .models import User

from django import forms

from django.forms import ModelForm

class SignUpForm(forms.ModelForm):

   class Meta:

        model = User

        fields = ('username','password','email')

models.py

---------

from django.db import models

#from django.core.urlresolvers import reverse

from django.contrib.auth.models import User

class Registration(models.Model):

    user = models.OneToOneField(User, on_delete=models.CASCADE)

urls.py

--------

urlpatterns = [

  url(r'^register/$', views.SignUpFormView, name= 'register'),

]

views.py

--------

def SignUpFormView(request):

    user_form = 'SignUpForm'

    template_name = 'test.html'

    if request.method == 'POST':

        form = user_form(request.POST)

        if form.is_valid():

            form.save()

            #username = form.cleaned_data.get('username')

            #password = form.cleaned_data.get('password')

            #email = form.cleaned_data.get('email')

            #user.save()

            return render(request, template_name, {'form':form})

    else:

        SignUpForm()

    return render(request, 'user_info/about.html')

test.html

---------

{% extends 'user_info/base.html' %}

{% block body %}

{% block content %}

{% for error in form.errors %}

    {{ form.errors | default_errors }}

{% endfor %}

<form method="post">

    {% csrf_token %}

    {{ form.as_p }}

    {% for field in form %}

        <p>

      username:<br>

      <input type="text" name="username"><br>

      password:<br>

      <input type="text" name="password"><br>

      email:<br>

      <input type="text" name="email"><br>

      {% for error in field.errors %}

           <p style="color: red">{{ error }}</p>

    {% endfor %}

        </p>

    {% endfor %}

    <button type="submit" value="Submit">sign up </button>

</form>

{% endblock %}

{% endblock %}

My issue is, when trying to launch the "register" page, its not going inside "if" condition in views.py, rather its going directly to "else" condition. 

I am tried many things under my reach, but couldn't resolve the issue, and stuck for 2 weeks now. 

Any help would be appreciated.
