This UnDockerizes Nick’s snakeeyes app from his Flask SASS course
To start create a virtual environment called ‘test’
Copy the contents of a folder from the course to a new folder called _test
pip install -r requirements.txt
If ‘Click’ is part of the requirements then run setup.py via pip: pip install —editable . This installs whatever is in setup.py and allows it to be edited without constantly ‘pip install’ing the new version. (I think that’s what it does…)
Make sure SERVER_NAME is set in the config.settings.py file or tests will fail. For dev set it to ‘localhost:5000’ or whatever port you are using
The app can be run from the app root folder with: python ./snakeeyes/app.py
The command line for testing with cli commands is: snakeeyes flake8 snakeeyes test snakeeyes cov For help on commands available use: snakeeyes
Even though Nick was using python2.7 in docker, I am using python 3.5 If this fails at some point I will check Nick’s compatibility video and code base. I am going through the course gradually so as not to come up against too many errors at one time.

Flask
Flask requires templates to be in the templates folder which is relative to the application folder (where you run the app). But I think each app in a blueprint can have its own templates folder…
DON’T do this anymore: app.run(debug=True)
DO THIS instead: $ export FLASK_APP=/path/to/file.py $ export FLASK_DEBUG=True $ flask run
** according to the creator of flask: flask-sqlalchemy - yes! flask-restful - not so much! to many opinions which can get in your way. voluptuous - yes!
