pip install django. (after this I usually use ln -s to link specific python site-package folder to vendor folder under the same django project.)

If you’re using Ubuntu linux for your django project, try following commands to setup your django project:

sudo apt-get install python3-pip
sudo apt-get install python3-venv
python3 -m venv django-project/vendor
cd django-porject
source vendor/bin/activate

安装Django：	pip install django  指定版本 pip3 install django==3.0

新建项目：	django-admin.py startproject mysite

新建APP :	python manage.py startapp blog

启动：python manage.py runserver 8080

同步或者更改生成 数据库：

python manage.py makemigrations

python manage.py migrate

清空数据库： python manage.py flush

创建管理员： python manage.py createsuperuser

修改用户密码： python manage.py changepassword username

Django项目环境终端： python manage.py shell

这个命令和 直接运行 python 进入 shell 的区别是：你可以在这个 shell 里面调用当前项目的 models.py 中的 API，对于操作数据的测试非常方便。

更多关于Django的命令在终端输入：python manage.py 查看

pip isntall -r requirements.txt

django settings.py setup:

ALLOWED_HOSTS = [your server ip address]
STATIC_ROOT = os.path.join(BASE_DIR, 'static')

run: python manage.py collectstatic

sudo apt-get install apache2
sudo apt-get install libapache2-mod-wsgi-py3
cd /etc/apache2/sites-available

configure your django vhost including aliases for your /static and /media folders, WSGI and python venv path.
And finally run 
$sudo a2ensite django-project
$sudo a2dissite 000-default.conf

$sudo service apache2 restart

django-admin startproject django_weber

python manage.py help

python manage.py startproject project_name

python manage.py startapp app_name

python manage.py makemigration

python manage.py sqlmigrate app_name migration_file_name (e.g. ecommence 0001)

python manage.py migrate

python manage.py createsuperuser

python manage.py runserver

python manage.py shell

from blog.models import Post
from django.contrib.auth.models import User

user = User.objects.get(id=1)

user = User.objects.first()
user = User.objects.last()

users = User.objects.filter(username='hok')

user = User.objects.filter(username='hok').first()
user.id
user.pk
user.username

user.post_set.all()
user.post_set.create(title='tltle', content='content')

pip isntall django-crispy-forms

If you’re using vscode for your python development IDE, remember to set

"python.autoComplete.extraPaths": ["/data/wwwroot/python/django_weber"],

in your settings.json file. This will help you to navigate through all your python modules.

Here’s Django official document to tell the difference between django-admin and manage.py: https://docs.djangoproject.com/en/3.0/ref/django-admin/

django-admin and manage.py¶

django-admin is Django’s command-line utility for administrative tasks. This document outlines all it can do.

In addition, manage.py is automatically created in each Django project. It does the same thing as django-admin but also sets the DJANGO_SETTINGS_MODULE environment variable so that it points to your project’s settings.py file.

The django-admin script should be on your system path if you installed Django via pip. If it’s not on your path, you can find it in site-packages/django/bin within your Python installation. Consider symlinking it from some place on your path, such as /usr/local/bin.

For Windows users, who do not have symlinking functionality available, you can copy django-admin.exe to a location on your existing path or edit the PATH settings (under Settings - Control Panel - System - Advanced - Environment...) to point to its installed location.

Generally, when working on a single Django project, it’s easier to use manage.py than django-admin. If you need to switch between multiple Django settings files, use django-admin with DJANGO_SETTINGS_MODULE or the --settings command line option.

The command-line examples throughout this document use django-admin to be consistent, but any example can use manage.py or python -m django just as well.
