Odoo: How to Inherit Controller

Sometime we need to modify a certain behavior when accessing odoo url (route). That time we need to do inheritance to odoo controller and then put our desired custom behavior when the url triggered. The way to inherit an odoo controller is slightly different than to inherit odoo object/model.

In this tutorial i will do inheritance on odoo route "/shop/checkout" which is the url route when doing website sale checkout, because i want to show some specific product information on the website that i cant call in the xml template unless i parse the data from python controller to xml view. Lets jump into it.

Here is the base controller

	from odoo import http, tools, _
	class WebsiteSale(http.Controller):
	@http.route(['/shop/checkout'], type='http', auth="public", website=True)
	def checkout(self, **post):
	# we have base code in here

Here is the inheritance controller

	from odoo.addons.website_sale.controllers.main import WebsiteSale
	class WebsiteSaleInherit(WebsiteSale):
	@http.route(['/shop/checkout'], type='http', auth="public", website=True)
	def checkout(self, **post):
	# use super to call prevously defined checkout methods so we not overriding the method but extend it.
	res = super(WebsiteSale, self).checkout(**post)
	# code your bugs in here ;)

in the example above i import base controller class (WebsiteSale) and use it as parameter on my new class (WebsiteSaleInherit). Thats it !!
