SQLA Flask Demo: Planets Database Example -- DELETE Functionality (Poor Pluto)
In this video we continue are ongoing example of a one-table SQLA (SQLAlchemy) database with planets data. We add WTForms to create a form that will show the user a drop-down select with planet names (and ids behind the scenes) to allow the user to delete a record (planet). Because the data was being changed, we moved queries into all of the routes (data-tables and API) to ensure the data displayed was not stale.
