Marcelo – Django

Django is a high-level Python web framework that encourages rapid development and clean, pragmatic design. It’s designed for building web applications quickly and seamlessly. In this tutorial, we will guide you through the installation and setup process of Django, and show you how to create a basic web application using Django.

First, you will need to have Python installed on your system. You can download Python from the official website (https://www.python.org/). Once Python is installed, you can proceed to install Django.

To install Django, open a command prompt or terminal and run the following command:

pip install django

This will install Django on your system. Once Django is installed, you can create a new Django project by running the following command:

django-admin startproject myproject

This will create a new directory named myproject with the following structure:

myproject/
    manage.py
    myproject/
        __init__.py
        settings.py
        urls.py
        wsgi.py

Now, navigate to the myproject directory and run the following command to start the Django development server:

python manage.py runserver

This will start the development server locally, allowing you to view your Django application in a web browser at http://127.0.0.1:8000/. You should see the Django welcome page if everything is set up correctly.

Next, let’s create a new Django app within our project. Run the following command to create a new app named myapp:

python manage.py startapp myapp

This will create a new directory named myapp with the following structure:

myapp/
    migrations/
    __init__.py
    admin.py
    apps.py
    models.py
    tests.py
    views.py

Now, let’s create a simple view in myapp/views.py:

from django.http import HttpResponse

def index(request):
    return HttpResponse("Hello, World!")

Next, we need to map this view to a URL in myproject/urls.py:

from django.urls import path
from myapp import views

urlpatterns = [
    path('', views.index, name='index'),
]

Now, restart the development server by running:

python manage.py runserver

Navigate to http://127.0.0.1:8000/ in your web browser, and you should see the message "Hello, World!" displayed on the page.

Congratulations! You have successfully created a basic Django web application. This is just the beginning, as Django offers a lot of powerful features and functionalities for building complex web applications. I recommend exploring the official Django documentation (https://docs.djangoproject.com/) to learn more about Django and its capabilities.

I hope this tutorial was helpful in getting you started with Django. Happy coding!
