View source for Set up Login System in Django

=Update urls.py=

You will need to add the following to your urls.py file:

<syntaxhighlight lang=python>
from django.contrib import admin
from django.urls import path, include # might need to add just include
from django.views.generic.base import TemplateView # add this line

urlpatterns = [
    path('admin/', admin.site.urls),
    path('accounts/', include('django.contrib.auth.urls')), # add this line
    path('', TemplateView.as_view(template_name='home.html'), name='home'), # add this line
]
</syntaxhighlight>
=Update settings.py=

You should find the templates section of the settings.py file. You will need to set the 'DIRS':

<syntaxhighlight lang=python>
TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [os.path.join(BASE_DIR, 'templates')],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]
</syntaxhighlight>

=Create a templates folder=

find the 'manage.py' file in your app folder. The templates folder should be in the same location as 'manage.py':

[[File:Templates 1.gif]]

Create a file called base.html in the templates folder, and copy this code:

<syntaxhighlight lang=html>
<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <title>{% block title %}Django Auth Tutorial{% endblock %}</title>
</head>
<body>
  <main>
    {% block content %}
    {% endblock %}
  </main>
</body>
</html>
</syntaxhighlight>

Create a file in the template folder called home.html, and copy this code:

<syntaxhighlight lang=html>
{% extends 'base.html' %}

{% block title %}Home{% endblock %}

{% block content %}
{% if user.is_authenticated %}
  Hi {{ user.username }}!
{% else %}
  <p>You are not logged in</p>
  <a href="{% url 'login' %}">login</a>
{% endif %}
{% endblock %}
</syntaxhighlight>

Create a new folder inside the template folder called registration, and create a new file called login.html, then copy this code:

<syntaxhighlight lang=html>
{% extends 'base.html' %}

{% block title %}Login{% endblock %}

{% block content %}
<h2>Login</h2>
<form method="post">
  {% csrf_token %}
  {{ form.as_p }}
  <button type="submit">Login</button>
</form>
{% endblock %}
</syntaxhighlight>
