Django 學習筆記 第一堂: 環境建置與框架特色

 

安裝 django 環境

# 基本套件安裝 ，先檢查有沒有裝 python3 & pip3

$python3 -V

$sudo apt install python3-pip

# 已安裝套件查詢

$pip3 list

Using Django inside a Python virtual environment

Install the tool using pip3:

＄sudo pip3 install virtualenvwrapper

# 加入 .bashrc

export WORKON_HOME=$HOME/.virtualenvs

export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3

export VIRTUALENVWRAPPER_VIRTUALENV_ARGS=' -p /usr/bin/python3 '

export PROJECT_HOME=$HOME/Devel

source /usr/local/bin/virtualenvwrapper.sh

# refresh env 變數

$source ~/.bashrc

Using a virtual environmentSection

There are just a few other useful commands that you should know (there are more in the tool documentation, but these are the ones you'll use regularly):

• deactivate — Exit out of the current Python virtual environment
• workon — List available virtual environments
• workon name_of_environment — Activate the specified Python virtual environment
• rmvirtualenv name_of_environment — Remove the specified environment.

# 新創一個虛擬環境名稱

netsys@netsys [django_test] $mkvirtualenv my_django_environment

#開好之後狀態就會呈現 (my_django_environment)，用用指令離開環境

(my_django_environment) netsys@netsys [django_test] $deactivate

#因為環境創過，之後就用 workon 去開

netsys@netsys [django_test] $workon my_django_environment

# 用 django-admin 開創一個 web

netsys@netsys$ mkdir django_test

netsys@netsys$ cd django_test

netsys@netsys [mytestsite]$ django-admin startproject mytestsite

### Django 網頁架構，可以用 tree　來檢視一下

netsys@netsys [django_test] $ tree ./mytestsite/

./mytestsite/

# 藉由更改 settings.py ALLOWED_HOSTS 的設定，允許 用public ip 連，不然他預設就是 127.0.0.1

ALLOWED_HOSTS = ['*']

#更改後就可以指定 ip 給他囉~(預設 port 8000)

$python manage.py runserver 140.113.220.167:8080

You have 15 unapplied migration(s). Your project may not work properly until you apply the migrations for app(s): admin, auth, contenttypes, sessions.

Run 'python manage.py migrate' to apply them.　　　　＃＃＃　　如果出現以上　　，就執行　　python manage.py migrate

Django version 2.1.5, using settings 'mytestsite.settings'

Starting development server at http://140.113.220.167:8080/

Quit the server with CONTROL-C  .........(只要有和網頁互動就會有 console log post 出來~~~~)

因為我再vm有轉NAT指定某個port給django，所以固定用8000給他。

$python3 manage.py runserver 10.0.2.15:8000
