Django Authentication and Authorization
Authentication and Authorization in Django?
Implementing user authentication and authorization is crucial for securing your Django web applications.
As for Django, it provides an in-built authentication system, thereby dealing with the issue of user account and permission management much smoothly.
Implementing user authentication:
Django provides built-in views and forms for user authentication, making it easy to set up login and logout functionality.
# urls.py
from django.urls import path
from django.contrib.auth import views as auth_views
from . import views
urlpatterns = [
path('login/', auth_views.LoginView.as_view(), name='login'),
path('logout/', auth_views.LogoutView.as_view(), name='logout'),
]
Using built-in authentication views and forms:
Django's built-in authentication views handle the login and logout process for you.
You can use them directly in your URL configurations.
login.html
<!-- login.html -->
<form method="post">
{% csrf_token %}
{{ form.as_p }}
<button type="submit">Login</button>
</form>
logout.html
<!-- logout.html -->
<form method="post">
{% csrf_token %}
<button type="submit">Logout</button>
</form>
Customizing authentication and authorization behavior:
You have the ability of configuring web-security in Django using classes and self-written middleware for authentication and authorization behavior.

from django.contrib.auth.decorators import login_required
@login_required
def my_view(request):
# Your view logic here
pass

class MyModelUpdateView(PermissionRequiredMixin, UpdateView):
model = MyModel
fields = ['field1', 'field2']
permission_required = 'myapp.change_mymodel'
