Exploring Django's Third-Party Packages: Top Libraries You Should Know

#django #python #programming #tutorial

Django is a high-level, open-source Python web framework designed to help developers build web applications efficiently. It is maintained by the Django Software Foundation.

Django encourages the use of reusable modules and follows the "batteries included" approach, offering a comprehensive suite of features and functionalities out of the box. Django also follows the model-view-controller (MVC) architectural pattern, emphasizing the reusability, maintainability, and rapid development of web applications.

In this article, we will look at the top libraries that should be known. So, let's embark on a journey to explore Django's third-party packages and discover the top libraries that will elevate our Django development experience to new heights.

Django Packages: An Overview

Django Packages play a significant role in expanding the capabilities of the Django web framework. They are third-party libraries or modules that developers can integrate into their Django projects to enhance functionality, streamline development, and save time. These packages are built by the Django community and provide additional features, tools, and utilities that complement the core Django framework.

The Django Packages community is a central hub for discovering, evaluating, and sharing these third-party packages.

Categories of Django packages include and are not limited to Authentication, API Integration, Content Management, Form Handling, Search, Database, Testing, and Deployment.

Top Django Third-Party Packages

Django REST Framework (DRF)
Django REST Framework is a famous, powerful, and flexible toolkit for building Web APIs in Django. It provides a set of reusable components and tools to simplify API development, including serialization, authentication, permissions, and view sets.

DRF is suitable for developing RESTful APIs with Django, enabling easy creation and management of API endpoints. It supports various authentication schemes, including token authentication, session authentication, and OAuth2.

DRF offers features like serialization, content negotiation, pagination, filtering, and validation, making API development efficient and consistent. To install this package using pip :

pip install djangorestframework
Enter fullscreen mode Exit fullscreen mode

After installing, add 'rest_framework' to the INSTALLED_APPS list in the Django project's base settings.

# settings.py
INSTALLED_APPS = [
    ...
    'rest_framework',
    ...
]

REST_FRAMEWORK = {
    'DEFAULT_AUTHENTICATION_CLASSES': [
        'rest_framework.authentication.TokenAuthentication',
        'rest_framework.authentication.SessionAuthentication',
    ],
    'DEFAULT_PERMISSION_CLASSES': [
        'rest_framework.permissions.IsAuthenticated',
    ],
}
Enter fullscreen mode Exit fullscreen mode

DJ-Database-URL
DJ-Database-URL is a package that allows easy configuration of database settings in Django projects using environment variables or URLs. It provides a convenient way to manage database settings, especially in production environments where URLs typically provide database connections.

The package supports popular database backends, including PostgreSQL, MySQL, SQLite, and others. Run the following command to install the package using pip:

pip install dj-database-url
Enter fullscreen mode Exit fullscreen mode

After installing the package, set the DATABASE_URL environment variable or provide the database URL directly in the Django project's settings.py. Then import and use dj_database_url.config() to parse the database URL and configure the database settings. Below is an example

# settings.py
import dj_database_url

DATABASES = {
    'default': dj_database_url.config(default='sqlite:///:memory:')
}
Enter fullscreen mode Exit fullscreen mode

WhiteNoise
WhiteNoise is a package that allows the efficient serving of static files in Django applications. It replaces the default Django development server for serving static files, providing better performance and caching.

WhiteNoise is suitable for deploying Django applications to production, where serving static files efficiently is essential. It also helps handle high-traffic situations by serving static files directly from the application server, reducing the need for additional infrastructure.

pip install whitenoise
Enter fullscreen mode Exit fullscreen mode

After installing, add 'whitenoise.middleware.WhiteNoiseMiddleware' to the MIDDLEWARE list in settings.py.

# settings.py
MIDDLEWARE = [
    ...
    'whitenoise.middleware.WhiteNoiseMiddleware',
    ...
]

STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles')
STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage'
Enter fullscreen mode Exit fullscreen mode

Django Cors Headers
Django Cors Headers is a package that enables Cross-Origin Resource Sharing (CORS) headers in Django applications. It is useful when building APIs or web applications that need to handle requests from different domains. It also helps overcome the browser's same-origin policy and allows communication between front-end applications and backend APIs hosted on different domains.

By configuring CORS headers, access permissions can be controlled and the security of our Django application is ensured. To get started with this package,

pip install django-cors-headers
Enter fullscreen mode Exit fullscreen mode

After installing, add 'corsheaders' to the INSTALLED_APPS list in the Django project's settings. Also, add 'corsheaders.middleware.CorsMiddleware' to the MIDDLEWARE list in settings.py. For example

# settings.py
INSTALLED_APPS = [
    ...
    'corsheaders',
    ...
]

MIDDLEWARE = [
    ...
    'corsheaders.middleware.CorsMiddleware',
    ...
]

CORS_ORIGIN_ALLOW_ALL = False
CORS_ORIGIN_WHITELIST = [
    'http://example.com',
    'https://example.com',
]
Enter fullscreen mode Exit fullscreen mode

Django Filter
Django Filter is a package that simplifies the process of filtering querysets in Django based on user-defined parameters. It provides a set of filter backends and filter fields to easily create customizable filters for model-based querysets.

Django Filter is useful when building applications that require advanced filtering options, such as search functionality or filtering based on specific model fields. The package offers various filter options including exact matches, range queries, lookup filters, and custom filter methods. To install,

pip install django-filter
Enter fullscreen mode Exit fullscreen mode

Then add 'django_filters' to the INSTALLED_APPS list in the Django project's settings.

# settings.py
INSTALLED_APPS = [
    ...
    'django_filters',
    ...
]
Enter fullscreen mode Exit fullscreen mode

To configure or use, we will need to define filter classes by subclassing django_filters.FilterSet and specify the model and fields to filter. For example,

# models.py
from django.db import models

class Book(models.Model):
    title = models.CharField(max_length=100)
    author = models.CharField(max_length=100)
    publication_date = models.DateField()

# filters.py
import django_filters

class BookFilter(django_filters.FilterSet):
    title = django_filters.CharFilter(lookup_expr='icontains')
    author = django_filters.CharFilter(lookup_expr='icontains')
    publication_date = django_filters.DateFromToRangeFilter()

    class Meta:
        model = Book
        fields = ['title', 'author', 'publication_date']

# views.py
from django_filters.rest_framework import DjangoFilterBackend
from rest_framework import filters

class BookListAPIView(generics.ListAPIView):
    queryset = Book.objects.all()
    serializer_class = BookSerializer
    filter_backends = [DjangoFilterBackend, filters
Enter fullscreen mode Exit fullscreen mode
