Hello, im working with Django tutorial from Mosh.
Yesterday i’ve replaced my original “storefront” project with the storefront downloaded from resource files from course files.

Django is saying there is no product with id=1 (pk) found in the database.

Make sure you have run all your migrations and check your db settings are properly configured like db name, user password etc and server is running and all your models are properly defined.

Also check in pgadmin in the products table that there is a product with primary key 1 exists and you can connect and view that record in the table without errors
