Furthermore, well-documented technologies ensure ease of adoption by developers beyond the framework’s creators. This assurance empowers developers, assuring them of Django’s usability across varied use cases without significant hurdles.
Distinguishing Django’s Framework Architecture
Django adopts the “Model, View, and Template” (MVT) framework as its architectural foundation, differentiating itself from the Model-View-Controller (MVC) framework where ‘C’ denotes “Controller.” Understanding the divergence between MVT and MVC frameworks and discerning their relative strengths becomes pivotal.
The principal distinction lies in Django’s unique approach, where the framework itself acts as the controller, handling all associated responsibilities. In essence, Django’s templates effectively manage controller-centric tasks, prompting curiosity about the roles of the three framework components.
Model
The model, functioning as the data interface, serves as the bridge connecting the user interface to the database. Responsible for data maintenance, it embodies the logical core driving the entire application and is closely linked to databases like MySQL and Postgres, among others.
View
Representative of the user interface, the view encompasses elements visible when navigating a website through browsers. It encompasses various components such as CSS, HTML, JavaScript, Jinja files, and other frontend technologies.
Template
Templates play a crucial role in simplifying the creation of web applications, especially for complex operations or functions. Comprising static sections of specific HTML output and specialized syntax dictating the insertion of dynamic data, templates facilitate the creation of dynamic web content. Such dynamic content often pertains to scenarios where personalized user-specific data is vital, seen in fintech transactions or social media posts.
Setting Up a Fundamental Django Project or App
Before delving into the technical directives, it’s essential to differentiate between Django projects and Django applications.
Django Project
A Django project serves as the overarching assembly of configuration files and applications, orchestrating the entire web application.
Django App
A Django application constitutes a standalone subset within the Django project, designed to execute specific business logic. A Django project can encompass anywhere from zero to multiple apps.
Django apps are distinct in that they operate independently of other apps, irrespective of whether they belong to the same or different Django projects. Consequently, theoretically, an app from one project can be seamlessly transferred to another, with or without alterations.
For instance, envision the Django project as an entire website and Django apps as discrete constituents within that site. These apps might include components for articles, fixtures, results, or ranking tables. Their interactions occur through meticulously documented public classes and accessor methods.
Creating a Django Project
Having grasped the concept of Django projects and apps, let’s navigate the steps involved in crafting a fundamental Django project.
To initiate a new Django project, execute the following command: django-admin startproject myproject.
Executing this command generates a foundational folder structure for your Django project, constituting five default files. This basic framework equips you to construct a single-page application.
Before progressing further, let’s delve into the roles of the five files within a Django project.
manage.py: This file functions as a handy shortcut facilitating interaction with your project via the command line. It enables the execution of management commands pertinent to your project, such as launching the server or synchronizing the database. To access a comprehensive list of executable commands using the manage.py file, input the following code in the command window: $ python manage.py help.
init.py: An empty file serving as a Python package, utilized for initiating package-specific code when the package or its module is imported.
settings.py: Containing the project’s comprehensive settings, this file manages the registration of created applications, static file locations, database configuration specifics, and more. It’s a pivotal file utilized extensively throughout the project’s developmental phase.
urls.py: Responsible for mapping routes and paths within a project, this file comprises all the project’s links and functions to invoke.
wsgi.py: Serving as a gateway interface for deploying the project in WSGI, this file facilitates communication between your Django application and the web server.
Another advantageous aspect of Django is its pre-installed web server, simplifying local project execution during the development stage. To test the project, use the command: python manage.py runserver.
Creating a Django app is a critical step within Django projects, aiding in the organization of source code. It’s important to note that running a Django app necessitates a Django project. After crafting a Django project, the creation of a Django app follows. Two methods facilitate this:
Firstly, utilize the django-admin command line utility by executing the following code: django-admin startapp <new app>. Secondly, leverage the manage.py file to implement the startapp command: $ python manage.py startapp <new app>.
Once the startapp command is executed, you’ll notice a freshly created folder bearing the name you designated—in this scenario, named “new app”—added to your existing folder structure. This new folder includes several other Python files integral to your Django app’s functioning.
During the development of your web application, a significant portion of your time will be spent within the Django app folder. While the settings.py folder will be frequently utilized, most of the functionality will be constructed within the Django app named “new app.”
Upon inspection of your directory at this stage, besides the initial five essential files covered during the Django project creation, you’ll encounter additional files serving specific purposes:
models.py: This file serves to declare the web application’s entities, allowing Django to interact with the web application’s database. Django automatically translates these models into database tables.
migrations/: This directory stores a collection of files that monitor modifications made to the models.py file. Its role is to ensure synchronization between the database and models.py.
admin.py: Functioning as a configuration file for the built-in Django app known as the Django Admin.
apps.py: A configuration file designed specifically for the app.
tests.py: This file is utilized to script unit tests tailored for the app.
views.py: Within this file lies the code logic of your app, managing the request/response cycle of the web application.
At this stage, you’ve successfully established a Django project encompassing a Django app. The subsequent steps involve delving into Django’s capabilities and ideating unique projects to develop using its framework.
What are the Applications of Django?
Django’s origins trace back to its initial development to power the web application of the Lawrence Journal-World, a newspaper publisher. This historical context highlights Django’s proficiency in handling extensive content, media files, and significant web traffic—a niche it initially catered to.
However, its capabilities transcend beyond the publishing industry. Developers swiftly recognized the broad potential of Django beyond content-heavy platforms. Consequently, they began leveraging this versatile framework to construct diverse applications ranging from e-commerce websites to travel and booking platforms, and even social media networks.
