hi all,

created a custom app using Daniel Reis book Odoo 12 Development Essentials, now i want to remove/delete it completely with all entries in database too. i have deleted from user interface in browser but it contains models in database ( may be other entries too some where in database ), so how I can remove it completely?  i can have fresh environment and, i can give my VM to someone else to learn while following those steps in the same book.

regards

EDIT: odoo 14 third party development learning material is still hard to find.
