Controllers

Controllers in Bast handle the logic of our app as stated in the MVC paradigm M - Model | V - View | C - Controller. To create controllers in Bast

$ panther create:controller MyController

This creates a MyController.py file in the controller directory. The skeleton for the MyController file is

from bast import Controller


class MyController(Controller):
    pass

You can then create any method and use the methods inherent in the controller class
