Start Django on PythonAnywhere

• Open PythonAnywhere Console;

• tools and ven

python3 --version
mkvirtualenv django3 --python=/usr/bin/python3.7
workon django3
pip install django
python3 -m django --version

• install sample code for dj4e

mkdir djProjects
cd djProjects
git clone https://github.com/csev/dj4e-samples
cd dj4e-samples
pip install -r requirements.txt
python manage.py check
python manage.py makemigrations
python manage.py migrate

python3 manage.py createsuperuser
python3 manage.py runscript gview_load
python3 manage.py runscript many_load

• build my own application

cd ~/djProjects
django-admin startproject mysite
vim ~/djProjects/mysite/mysite/settings.py
"""/ upate ALLOWED_HOSTS
ALLOWED_HOSTS = ['*']
"""

cd ~/djProjects/mysite
python manage.py check

• open my own web app
  • go to web tab
  • add a new web application, manually, get settings done
    • Source code: /home/SheldonLee/djProjects/mysite
    • Working directory: /home/SheldonLee/djProjects/mysite
    • Virtualenv: /home/SheldonLee/.virtualenvs/django3
  • edit /var/www/..._..._..._com_wsgi.py like this:

  import os
  import sys
  
  path = os.path.expanduser('~/djProjects/mysite')
  if path not in sys.path:
      sys.path.insert(0, path)
  os.environ['DJANGO_SETTINGS_MODULE'] = 'mysite.settings'
  from django.core.wsgi import get_wsgi_application
  from django.contrib.staticfiles.handlers import StaticFilesHandler
  application = StaticFilesHandler(get_wsgi_application())
  

  • click reload ....pythonanywhere.com

  • click my url sheldonlee.pythonanywhere.com

• syncro PythonAnywhere to github

cd ~/djProjects
git init

# after create an empty ropo on github:
git remote add origin git@github.com:sheldonldev/djProjects_onPyAnyw.git
git add .
git commit -a

ssh-keygen -t rsa -C my_email@domain.com
cat ~/.ssh/id_rsa.pub

git push --set-upstream origin master

• syncro github to local laptop

cd $hub/mysite_test
git clone git@github.com:sheldonldev/djProjects_onPyAnyw.git

• setup in local laptop
  • start a virtural env the same as PythonAnywhere

  export all_proxy=socks5://127.0.0.1:1080
  conda create --name dj_py37 python=3.7
  conda activate dj_py37
  
  export all_proxy=""
  pip install pysocks
  export all_proxy=socks5://127.0.0.1:1080
  pip install django
  

  • set IDE in pyCharm:
    • set interpreter to dj_py37;
    • enable django support in language and framework;
    • rightclick root dir, New - .ignor file - .gitignore;
• syncro local laptop to github

pip freeze -> requirements.txt
git add .
git commit -a
git push

• syncro github to PythonAnywhere

  cd ~/djProject
  git pull
  
  workon django3
  pip install requirements.txt
  

  • If you edit two places and push from one of the places, the push will work - but the push won’t work from the second place and pull won’t work either becausee you have local changes. If this is what you did, there is a simple workaround. On the system where you have un-pushed changes and want to do a pull before pushing, do this:

  git stash
  git pull
  git stash apply
  
  git add .
  git merge
  git pull
  

• reload application in the Web tab and visit it.
