Using the Flask CLI

| programming | python |

Who knew that flask had a cli? Previously I used to just use manage.py just like Django does it to “do stuff”. The CLI is great, but again it follows the theme of kind of wanting you to install your flask app. (I really should do this). So in order to get your app to work you must point the FLASK_APP variable to the actual python file (not your app module). This is true even if you have a true python module. For instance.

export FLASK_APP = blog/blog.py
flask run
Works, while
export FLASK_APP = blog
flask run
Does not. Even though blog consists of:
blog/
  __init__.py
  blog.py

Ink in the Stomach

Something I believe very strongly, mostly from observing changes in myself, is that, once you’ve shoved your own hands deep in the entrails of a building, you’ve permanently altered your entire relationship with the world.
