versioned with pyenv-win from chocolatey. not using pipenv (more powerfull - combines pip and venv, > pipenv shell, to switch to venv, packages in another dir), using pyenv-win with venv. not using a .gitignore, to save state of small project, all dependencies tracked.

pyenv-win installation:

• Chocolatey:

Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object System.Net.WebClient).DownloadString('https://community.chocolatey.org/install.ps1')) choco install pyenv-win

• Add to system path:

  [System.Environment]::SetEnvironmentVariable('PYENV',$env:USERPROFILE + ".pyenv\pyenv-win","User") [System.Environment]::SetEnvironmentVariable('PYENV_ROOT',$env:USERPROFILE + ".pyenv\pyenv-win","User") [System.Environment]::SetEnvironmentVariable('PYENV_HOME',$env:USERPROFILE + ".pyenv\pyenv-win","User")

• Add to user path:

  [System.Environment]::SetEnvironmentVariable('path', $env:USERPROFILE + ".pyenv\pyenv-win\bin;" + $env:USERPROFILE + ".pyenv\pyenv-win\shims;" + [System.Environment]::GetEnvironmentVariable('path', "User"),"User")

• restart VSC, or shell.
• Switched > Set-ExecutionPolicy to Unrestricted, (not recommended, check other options)
• If resetting PS session:

  Get-Process -Id $PID | Select-Object -ExpandProperty Path | ForEach-Object { Invoke-Command { & "$_" } -NoNewScope }

Commands (python, PS):

python -m venv .venv .venv\Scripts\activate python -m pip install -U pip python -m pip install --no-cache-dir -U django --prefer-binary pip list (or use pip freeze > packages.txt) to capture - use with pip install -r to gen dependencies django-admin startproject storefront . - some names not available?

• manage.py mod takes settings into account (smart wrapper), avoids "settings not configured err (with djang-admin after creating project)"

python manage.py runserver 9000 - by default -p 8000 python manage.py startapp playground python -m pip install --no-cache-dir -U django-debug-toolbar --prefer-binary - refer to https://django-debug-toolbar.readthedocs.io/en/latest/installation.html

VSC (setting python interpreter shell): - ctrl + shift + p - > Python: Select Interpreter - copy from pipenv --venv, if using pipenv, if on venv, select from .venv dir /bin/python

Git: - git remote add origin git@OTonGitHub:OTonGitHub/CWM-Django.git - git branch -M main - git push -u origin main

Project Sturcture: - playground (startapp): - migrations/, admin.py, apps.py (config), models.py, tests.py, views.py (request handler, not like MVC view) - for django-debug-tools to work, response needs to be in proper html, with html tag, body tag etc - When modelling: - minimal coupling, - high focus (cohesion, unix philosophy)

Views.py: - handling requests and giving response, request handler. - similar to actions. - architecturaly, views is not the right name, as view is what user sees, in django, that is template.

VSC shortcuts: - ctrl + k s (save all) - ctrl + b (folder structure show hide) - ctrl + ` (terminal) - ctrl + p or ctrl + e (searc and go to file)
