Usage:

to make use of django-userplus, you need to extend the model in your user model like so.

...
from userplus.models import UserPlus

class User(UserPlus):
    pass  # you can add other fields here.

django-userplus comes with signup and login forms out of the box, so in your views you can make use of the forms like so.

from userplus.forms import SignUpForm, SignInForm
from django.contrib.auth import authenticate

class SignUpView(View):
    def get(self, request):
        form = SignUpForm()
        ...

    def post(self, request):
        form = SignUpForm(request.POST)

        if form.is_valid:
            user = form.save()
            ...

class SignInView(View):
    def get(self, request):
        form = SignInForm()
        ...

    def post(self, request):
        form = SignInForm(request.POST)
        if form.is_valid():
            user = authenticate(**form.cleaned_data)
            if user:
                login(request, user)
                ...

Sign in with Username or Email :

To use django-userplus agnostic signin feature, add the following to your settings.py

...
AUTHENTICATION_BACKENDS = ['userplus.backends.UserPlusBackend']
...

This makes django.contrib.auth.authenticate username or email agnostic, i.e it would authenticate the user if she inputs her email or her username. So you can do this.

from django.contrib.auth import authenticate

user = authenticate(username='JohnDoe', password='MySecret')

or

from django.contrib.auth import authenticate

user = authenticate(email='[email protected]', password='MySecret')

If you use userplus SigninForm this already comes with a username_or_email field that auto-detects what the user has passed in.

User Activation key:

To set activation key on signup, add the following to settings.py.

...
USERPLUS_SET_ACTIVATION_KEY = True
...

you can also set an optional parameter for how long the key is valid for. This defaults to 2 days if not set;

...
USERPLUS_ACTIVATION_DAYS = 3  # valid for 3 days.
...

On Signup an activation key will then be set for the user. The user needs to activate this before she can login. After saving the user form on signup, an activation email can be sent like so.

...
user = form.save()
url = reverse('userplus_confirm_registration', kwargs={
                               'activation_key': user.activation_key})
user.email_user('Confirmation Email', url)

Password Validation:

Although django 1.9 comes with quite some useful password validators. You can also add Userplus pattern validator to enforce a stronger password. Simply add to the already existing AUTH_PASSWORD_VALIDATORS variable in settings.py.

...
AUTH_PASSWORD_VALIDATORS = [
    ...
    {
        'NAME': 'userplus.validators.PatternValidator',
    },
]

this would enusre the password contains uppercase and lowercase alphabet, Number and Special Character.
