Getting Started with Django and Basic Configuration

Django is a powerful and efficient Python web framework that follows the “Don’t Repeat Yourself” (DRY) principle, enabling developers to quickly build high-quality web applications. Today, we’ll explore Django’s basic configuration and core concepts!

Django installation and project creation

First, make sure you have a Python environment installed, then install Django via pip:

pip install django

Creating a new project is very simple:

django-admin start project myproject

This will generate a Django project structure named `myproject` in the current directory:

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

Detailed basic configuration

settings.py is the core configuration file for a Django project. Let’s take a look at some key settings:

# Application Register
INSTALLED_APPS=[
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'myapp', # your application name
]

# Database Config
DATABASES={
'default':{
'ENGINE':'django.db.backends.sqlite3',
'NAME':BASE_DIR/'db.sqlite3',
}
}

# Static File Config
STATIC_URL='/static/'
STATICFILES_DIRS=[BASE_DIR/"static"]

Create an application

A Django project consists of multiple applications. To create a new application:

python manage.py start app myapp

Each application has its own `models.py`, `views.py`, and `urls.py` files, implementing the MVC architecture.

Running the development server

Start the development server to view your project:

python manage.py run server
