Recurring Subscriptions

There is a recurring column on the Subscription table. A boolean value represents what happens upon the expiration of a users subscription. If true, then a scheduled job will run a rake task attempting to rebill the user through Stripe, and if successfull, renew their subscription for an additional year.

Scheduled Job

There is a scheduled job on Heroku that runs rake update_todays_expired_recurring_subscriptions once a day.

Rake Task

rake update_todays_expired_recurring_subscriptions calls Subscription.update_todays_expired_recurring_subscriptions

Subscription.update_todays_expired_recurring_subscriptions

This method gets all subscriptions where the expiration date is today and recurring is true. It then iterates through, calling update_if_charge_succeeds on each subscription instance.

#update_if_charge_succeeds

Calls #charge_user and if the charge succeeds, the #renew_subscription is called.

#charge_user

If the subscription has a purchaser and the purchaser has a Stripe customer id, the renewal_price of the subscription is calculated and billed to the purchaser through the Stripe API.

#renew_subscription

Creates a new subscription by duping the last one.
