Django – Tu nommes cela vivre ?

Django is a high-level Python web framework that encourages rapid development and clean, pragmatic design. It is designed to make web development easier by providing reusable components and tools that help developers build scalable and maintainable web applications.

In this tutorial, we will walk through the process of setting up a basic Django project called "T’appelles ça vivre?" and deploying it to a server.

Step 1: Installing Django
Before you can start building a Django project, you need to install the Django framework on your computer. You can do this by running the following command in your terminal:

pip install django

This will install the latest version of Django on your computer. Once the installation is complete, you can check if Django was installed successfully by running the following command:

django-admin --version

Step 2: Creating a Django project
To create a new Django project, run the following command in your terminal:

django-admin startproject tappelles_ca_vivre

This will create a new directory called "tappelles_ca_vivre" with the necessary files and folders to set up a Django project. Navigate to this directory using the cd command and run the following command to start the development server:

python manage.py runserver

You should see a message indicating that the development server is running. You can now open your web browser and navigate to http://127.0.0.1:8000 to see the Django project’s default homepage.

Step 3: Creating Django apps
Django projects are made up of multiple apps that handle different parts of the project’s functionality. To create a new app within your Django project, run the following command in your terminal:

python manage.py startapp myapp

This will create a new directory called "myapp" with the necessary files and folders to set up a Django app. You can create multiple apps within a Django project to organize your code and functionality.

Step 4: Configuring the Django project
To configure the Django project, you can modify the settings.py file within the project directory. This file contains settings for the project, such as database configuration, middleware, and static files. You can also set up the URLs for your project in the urls.py file within the project directory.

Step 5: Building views and templates
Django uses a templating language called Django Template Language (DTL) to build dynamic web pages. You can create templates within your Django app’s "templates" directory and render them using views. Views are Python functions that handle web requests and return responses.

To create a view, define a function within the views.py file of your app and then create a template file within the "templates" directory. You can then map the view to a URL in the urls.py file of your app.

Step 6: Deploying the Django project
To deploy your Django project to a server, you can use a web hosting service that supports Django applications. You will need to set up a web server (such as Nginx or Apache) to serve the Django project and configure it to run the Django application using WSGI.

Once the Django project is deployed, you can access it using the server’s URL and test that everything is working as expected.

In conclusion, Django is a powerful web framework that makes building web applications in Python easy and efficient. By following the steps outlined in this tutorial, you can set up a basic Django project, create apps, configure settings, build views and templates, and deploy the project to a server. Django’s robust features and extensive documentation make it a popular choice among developers for web development projects.
