Building a Django Application Video Tutorial

Welcome to this video tutorial on building a Django application. Django is a high-level Python web framework that encourages rapid development and clean, pragmatic design. In this tutorial, we will guide you through the process of creating a simple Django application from scratch.

Prerequisites

Before you start, make sure you have the following prerequisites:

Python installed on your system
Django installed (pip install django)
A text editor or IDE of your choice

Step-by-Step Guide

1. Setting Up the Project

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

django-admin startproject myproject

This will create a new directory named myproject with all the necessary files and directories for a Django project.

2. Creating an App

Next, create a new app within your project by running:

cd myproject
python manage.py startapp myapp

This will create a new directory named myapp with the basic files and directories for a Django app.

3. Defining Models

In your app directory, open the models.py file and define your models. For example:

from django.db import models

class Product(models.Model):
    name = models.CharField(max_length=100)
    price = models.DecimalField(max_digits=10, decimal_places=2)

This defines a simple Product model with a name and price field.

4. Creating Views

In your app directory, open the views.py file and define your views. For example:

from django.shortcuts import render
from .models import Product

def product_list(request):
    products = Product.objects.all()
    return render(request, 'product_list.html', {'products': products})

This defines a view called product_list that retrieves all products from the database and renders a template named product_list.html.

5. Creating Templates

Create a new directory named templates in your app directory. Inside this directory, create a new HTML file named product_list.html. Add the following content to this file:

<!DOCTYPE html>
<html>
<head>
    <title>Product List</title>
</head>
<body>
    <h1>Product List</h1>
    <ul>
        {% for product in products %}
            <li>{{ product.name }} - {{ product.price }}</li>
        {% endfor %}
    </ul>
</body>
</html>

This template displays a list of products with their names and prices.

6. Running the Development Server

To run the development server, navigate to your project directory and run:

python manage.py runserver

Open your web browser and go to http://127.0.0.1:8000/. You should see the product list displayed.
