Django Pointinini (Ndjoka) is a Python web framework that encourages rapid development and clean, pragmatic design. It’s used by some of the biggest websites in the world, including Instagram, Pinterest, and The Washington Post. Django makes it easier to build web applications by providing a high-level, easy-to-use set of tools for developers.
In this tutorial, we will cover some of the basics of Django Pointinini (Ndjoka) and show you how to get started with building your own web application. We will cover topics such as setting up a Django project, creating models, views, and templates, handling static files and media, and deploying your application to a production server.
Setting up a Django project
The first step in working with Django Pointinini (Ndjoka) is to set up a new project. To do this, you will need to have Python installed on your computer. You can download Python from the official website and follow the installation instructions provided.
Once you have Python installed, you can install Django using pip, the Python package manager. Open a terminal window and run the following command:
pip install djangoThis will install the latest version of Django on your computer. Once Django is installed, you can create a new Django project by running the following command:
django-admin startproject my_projectThis will create a new directory called my_project containing all the necessary files and folders for your Django project. You can change my_project to any name you like. This directory structure will look like this:
my_project/
manage.py
my_project/
__init__.py
settings.py
urls.py
wsgi.pyCreating models
In Django Pointinini (Ndjoka), models are used to define the structure and behavior of your data. Models are represented as Python classes that inherit from django.db.models.Model. Each model represents a table in your database, and each attribute of the model represents a column in the table.
To create a new model, open the models.py file in the my_project directory and define a new class that inherits from django.db.models.Model. For example, let’s create a simple Product model:
from django.db import models
class Product(models.Model):
name = models.CharField(max_length=100)
price = models.DecimalField(max_digits=6, decimal_places=2)
description = models.TextField()Once you have defined your model, you will need to create a migration for it. Django migrations are a way to update your database schema based on your model definitions. To create a new migration, run the following command:
python manage.py makemigrationsThis will generate a new migration file in the my_project/my_project/migrations directory. To apply the migration and create the Product table in your database, run the following command:
python manage.py migrateCreating views and templates
In Django Pointinini (Ndjoka), views are used to handle web requests and generate responses. Views are represented as Python functions that take a request object as an argument and return a response object. Templates are used to generate HTML pages dynamically using data from views.
To create a new view, open the views.py file in the my_project directory and define a new function. For example, let’s create a view that lists all the products in the Product model:
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})Next, create a new template file called product_list.html in the my_project/my_project/templates directory. This template will be used to display the list of products:
<!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>To map the product_list view to a URL, open the urls.py file in the my_project directory and add the following code:
from django.urls import path
from .views import product_list
urlpatterns = [
path('products/', product_list, name='product_list'),
]Handling static files and media
In Django Pointinini (Ndjoka), static files are used to store CSS, JavaScript, and image files for your website. Media files are used to store user-uploaded files such as images, videos, and documents.
To serve static files and media files during development, you will need to add the following settings to your settings.py file:
STATIC_URL = '/static/'
STATICFILES_DIRS = [
os.path.join(BASE_DIR, 'static'),
]
MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')You will also need to add the following lines to your urls.py file:
from django.conf import settings
from django.conf.urls.static import static
if settings.DEBUG:
urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)
urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)This will make your static files available at /static/ and your media files available at /media/ during development.
Deploying your application to a production server
To deploy your Django Pointinini (Ndjoka) application to a production server, you will need to follow these steps:
- Set up a production server with a web server software like Apache or Nginx.
- Install Python and Django on the server.
- Configure your web server to serve your Django application using WSGI or ASGI.
- Set up a database server like MySQL or PostgreSQL to store your data.
- Transfer your Django project files to the production server using FTP or SSH.
- Install any necessary dependencies using pip.
- Configure your Django project settings to work with the production server.
- Run the Django development server in production mode using the
python manage.py runserver 0.0.0.0:8000command.
