Make it possible to sign up - 30 days of Django

Making it possible for users to sign up is very easy thanks to the built in authentication system in Django. Let's begin with creating a new Django app for users:

$ python manage.py startapp userprofile

And then we need to append it to a list in the "settings.py" file.

INSTALLED_APPS = [
    ...
    'userprofile',
]

Django comes with a built in database model for users, so this app will only be used for views and templates. Open up userprofile/views.py, it should look like this:

from django.contrib.auth import login
from django.contrib.auth.forms import UserCreationForm
from django.shortcuts import render, redirect

def signup(request):
    if request.method == 'POST':
        form = UserCreationForm(request.POST)

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

            login(request, user)

            return redirect('frontpage')
    else:
        form = UserCreationForm()
    
    return render(request, 'userprofile/signup.html', {'form': form})

Most of this code should hopefully start looking familiar and make sense now?
We import a method from Django for logging in the user, and a form for creating the user. If the form is valid, we store the form in a variable called "user", then we log in the user and redirect to the front page.

Next step then is to create the folder for the template (templates/userprofile) and the template inside "signup.html". It should look like this:

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

{% block content %}
    <div class="edit-tasks">
        <h1>Sign up</h1>

        <form method="post" action=".">
            {% csrf_token %}

            {{ form.as_p }}

            <button>Sign up</button>
        </form>
    </div>
{% endblock %}

So yet again, a very simple template where we render a form.

The last step then is to create a url file and also appending it in the main urls.py file. Create a file called urls.py in the new userprofile app:

from django.urls import path

from . import views

urlpatterns = [
    path('sign-up/', views.signup, name='signup'),
]

And then add it in the main urls.py file:

from django.urls import path, include

urlpatterns = [
    path('', include('userprofile.urls')), # New
    path('', include('task.urls')),
    path('', include('category.urls')),
]

Try to create a user and see what happens. In the next part, we will handle log in and making a few checks if the user is authenticated or not.
