Django Introduction

Django is a high-level Python web framework that enables developers to build robust and scalable web applications quickly. It encourages clean and pragmatic design by emphasizing reusable and maintainable code.

Step 1: Installing Django

To start using Django, you need to install it. Use the following command:

            pip install django

To confirm that Django has been installed successfully, type:

            django-admin --version

Step 2: Creating a Django Project

Once installed, you can create a new Django project using the following command:

            django-admin startproject myproject

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

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

Step 3: Running the Development Server

Navigate to your project folder and run the development server:

            cd myproject
            python manage.py runserver

After running this command, open your browser and go to http://127.0.0.1:8000 to see the default Django welcome page.

Step 4: Creating a Django App

Django organizes code into apps. To create an app, use the following command:

            python manage.py startapp myapp

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

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

Step 5: Writing a View

In the views.py file of your app, define a simple view function:

    from django.http import HttpResponse

    def home(request):
        return HttpResponse("Hello, Django!")

Step 6: Configuring URLs

Add the new view to your project's URL configuration. Open urls.py in the project folder and update it:

    from django.contrib import admin
    from django.urls import path
    from myapp.views import home

     urlpatterns = [
        path('admin/', admin.site.urls),
        path('', home, name='home'),
    ]

Now, navigate to http://127.0.0.1:8000 in your browser to see "Hello, Django!" displayed on the page.

Step 7: Next Steps

This is just the beginning! With Django, you can:

  • Define models for database interaction
  • Use Django's powerful admin interface
  • Implement templates for dynamic HTML
  • Handle forms and user authentication
