Chapter 1 Building A Blog Application

1. Installing Django

Installing Python3 on Mac:

bash 复制代码

pip3 install python3

Creating Virtual Environment:

bash 复制代码

python3 -m venv .venv

Installing Django with pip3:

bash 复制代码

pip3 install django

Creating your first project:

bash 复制代码

django-admin startproject blog

Let's take a look at the generated project structure:

These files as follows:

manage.py

A command-line utility to interact with your project. It is a thin wrapper around the django-admin.py tool.
blog/

Your project directory consists of the following files:
- init.py
  
  An empty file that tells Python to treat the blog directory as a Python module.
- settings.py
  
  Settings and configuration for your project. Contains initial default settings.
- urls.py
  
  The place where your URL patterns live. Each URL defines here is mapped to a view.
- wigs.py
  
  Configuration to run your project as a WSGI application.

Note that:
The generated settings.py file includes a basic configuration to use a SQLite database and a list of Django applications that are added to your project by default. We need to create the tables in the database for the initial applications.

Click New Terminal and run the following commands:

python 复制代码

cd blog

python 复制代码

python3 manage.py migrate

The tables for the initial applications have been created in the database.
