• Create a file named forms.html in templates > mainApp and add the following to it.

<!DOCTYPE html>
<html>
    <head>
        <meta charset="utf-8">
        <title>Sign Up</title>
        <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css">
    </head>
    <body>
        <div class="container">
            <h1>Sign Up</h1>
            <form method="POST">
                {{ form.as_p }}
                {% csrf_token %}
                <input type="submit" class="btn btn-primary" value="Submit">
            </form>
        </div>
    </body>
</html>

• In urls.py in Project Folder add the following line to urlpatterns:

    url(r'^signup/', views.signup, name='signup')

• In views.py in mainApp add the following function

def signup(request):
    form = NewUserForm()
    if request.method == "POST":
        form = NewUserForm(request.POST)

        if form.is_valid():
            form.save(commit=True)
            return users(request)
        else:
            print("ERROR: FORM INVALID")
    return render(request, 'mainApp/signup.html', {'form':form})

• Add the following to urls.py file under mainApp folder in urlpatterns list.

    url(r'^signup', views.signup, name='signup')

• Create a file named forms.py in mainApp and add the following code to it.

from django import forms
from mainApp.models import User


class NewUserForm(forms.ModelForm):
    class Meta:
        model = User
        fields = '__all__'

• Now the form is ready and connected to database. Run the server to test it in browser.
