If we have multiple developers collaborating on development, we might feel uncomfortable putting the details of the configuration of our database (potentially including passwords!) into our configuration management system.

Introduce a change to the schema to add a price to a line item. Make sure that the migration fills in this value. Modify the add_product method in the Cart model to capture this information from the Product. Modify the total_price method in the LineItem model to compute the sum using this value. Modify the _line_item partial to display this value.

Once you have this change working, deploy this change. Discuss
