selling products associated with dates
In my specific example i'm selling courses. You can buy 3 types of course bronze, silver and gold. The courses are always the same but will occur on different dates.
It seems sensible to create 3 product types: bronze, silver and gold. Then create a product display for each new course with a product reference field to add the 3 product types, the product display content type will have a date field. In this way it can be used in calendars and simplifies the product creation process.
My problem is - when someone adds a product to the cart it doesn't contain the date of the course, as this isn't part of the product, only the product display.
Am I doing this the right way, if so how can i get product display fields into the cart and into the order.
