Ruby on Rails development from scratch (Windows) (vii)-Create online shopping page

In the previous essay, we created a maintenance list page for the products as shown:

This time we use the products list maintained above to create a shopping page for end users.

1. Create controller (Controller), named Store, we create it through the command line:

Depot> Ruby script/generate Controller Store Index

Open the Store_controller.rb file in the. rails_apps\depot\app\controllers directory and add code to it:

def index
@products = Product.salable_items
End

Of course, we also need to define the Salable_items method for product, open the Product.rb file in the Rails_apps\depot\app\models directory, and add code:

def Self.salable_items Find
(: All,
: Conditions => "date_available <= Now ()",
: Order => "Date_ Available desc ") End
