Introduction:
Django is a powerful development framework. It helps developers quickly build high-quality web applications. This article will introduce in detail how to use Django commands to create a new project and give specific code examples.

1. Install Django

Before starting to create a Django project, we first need to install Django on the computer. You can install the latest version of Django in the terminal through the following command:

pip install Django

2. Create a project

1. Open the command line interface and enter the directory where you want to create the project.
2. Create a new Django project using the following command:

django-admin startproject myproject

This will create a folder called "myproject" in the current directory and generate a Django project in it basic structure.

3. View the project structure

After the project is successfully created, you can view the directory structure of the project through the following command:

cd myproject
ls

After running the above command, you will see something like Based on the following directory structure:

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

• manage.py: A command line utility for executing various Django commands.
• myproject/: This folder is the main directory of the project and contains files and sub-applications related to project settings.
• __init__.py: An empty file that tells Python that the directory is a Python package.
• settings.py: Contains project settings and configuration, such as database connection, static file path, etc.
• urls.py: Define the URL routing rules of the project.
• wsgi.py: An entry point for deploying your project to a WSGI-compatible server.

4. Run the project

1. Use the following command to enter the project directory:

cd myproject

2. Run the following command to start the Django development server:

python manage.py runserver

After running successfully, you will see output similar to the following:

Starting development server at http://127.0.0.1:8000/
Quit the server with CONTROL-C.

3. Enter http://127.0.0.1:8000/ in the browser, You will see Django’s default welcome page.

5. Create an application

The Django application is a component of the project and can be regarded as a sub-module of the project. The following will demonstrate how to create an application named "blog":

1. Use the following command to create a new application in the project directory:

python manage.py startapp blog

This will Create a folder named "blog" in the project directory, which contains the basic structure of the application.

2. Add the newly created application to the INSTALLED_APPS list in the myproject/settings.py file:

INSTALLED_APPS = [
    ...
    'blog',
]

Six , Writing views

Django’s views process user requests and return corresponding functions. A simple view example will be shown below:

1. Write the following view in the blog/views.py file:

from django.http import HttpResponse

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

2. In blog/urls.pyAdd URL routing rules to the file:

from django.urls import path
from . import views

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

7. Run the application

1. Run the following command to start the Django development server:

python manage.py runserver

2. Enter http://127.0.0.1:8000/blog/hello in the browser, you will see the "Hello, Django!" page.
