Product Subsystem

The product subsystem is responsible for tracking all product-related data. Purchasable products are typically Programs and Course Runs. Pricing information is tracked as immutable data for the sake of historically accurate pricing for orders.

Data Models

@reversion.register(exclude=("content_type", "object_id", "created_on", "updated_on"))
class Product(TimestampedModel):
    """
    Representation of a purchasable product. There is a GenericForeignKey to a Course or Program.
    """
    content_type = models.ForeignKey(ContentType)
    object_id = models.PositiveIntegerField()
    content_object = GenericForeignKey("content_type", "object_id")

This will utilize django-reversion to version product data.

APIs

The API that would be primarily needed would be one to read back product data. It is presumed that data entry is done through django-admin:

• GET /api/v0/products/ -> returns a paginated list of products

• GET /api/v0/products/1/ -> returns a single product
