Selling Content with Drupal Commerce using Content Access and Roles

In this screencast we'll use Drupal's built-in access control mechanisms (using the Content Access module) to grant access to premium content to users who have a "premium" role.

Here's the recipe:

• Enable Content Access and the ACL (optional) module.
• Create a role called "premium"
• Create a content type called "Premium Content" and put some great content in it.
• Verify that users can only access the premium content if they have the premium role.
• Create a product representing the premium role.
• Create a rule that grants the premium role on order completion:
  • After updating an order
  • If the order state is Completed
  • And the order contains our premium product
  • Add a role to the user who is the owner of the order

That's really all there is to it.
