Feature requested here: https://meta.discourse.org/t/subscriptions-allow-users-to-purchase-one-time-products-multiple-times/173732/
There may be cases where a site admin wants to allow the repurchasing of a product. This implements the functionality by adding a repurchaseable toggle in the admin screen when creating a product. This saves an attribute to the Stripe product metadata.
When a user has already purchased an item with this toggle enabled, they will be able to purchase it again when browsing to `/s`.
Adds full support to create coupon/promo codes in the Admin > Plugins > Subscriptions section of the plugin. The Create Coupon button opens a form on the same page, and the active checkboxes toggle the active status of the coupon code.
This adds support for Stripe Promo Codes in the user checkout process.
Also adds a discounted field to User > Billing > Subscriptions to show the amount or percent discounted.
This does not currently add in support for creating promo codes in the Subscriptions interface (that will come at a later point in time). Instead a coupon can be created with a promo code right from the Stripe dashboard.
An implementation of refunds from the Admin dashboard. To refund, go to Plugins > Subscriptions > Subscriptions then click the `Cancel` button. You'll be presented with a modal. If you wish to refund only the most recent payment, check the box.
This only implements refunds for Subscriptions, not One Time Payments. One Time Payments will still need to be handled manually at this time.
Improves the subscription flow for anonymous users by making the routes available, and showing a login button. Clicking login from this page will save a `destination_url` cookie so that when logging in they're redirected back to the subscription page they were at.
The code in the plugin needed a dramatic cleanup. This refactor collapses the Plan/Product/Subscription controllers on the backend into one new controller: `SubscribeController`.
This reduces N+1 calls to the back end during the subscription process and simplifies use of the code.
I've also removed a bunch of dead code and refactored some logic into methods for easier readability. No feature/functionality changes in this commit; only refactoring. However, refactoring will allow for implementation of better anonymous user handling, so this is largely a foundation to enable making that change.
Previously, when a user canceled a subscription, the access would revoke
immediately on Discourse vs. at the end of the billing period. This
commit changes the behavior to remove membership at the end of the
billing period using Stripe's `cancel_at_period_end` attribute on the
Subscription object.
This commit now requires the setup of webhooks for subscription
processing to occur correctly.
Building off the foundation of using the Prices API, this PR adds the ability to create a one-time purchase plan for any product, which then can add a user to the specified plan group.
Some things to be aware of:
One-time purchases cannot have trials.
One-time purchases use the Invoice API instead of Subscriptions. Invoices are created then charged immediately.
Users should receive emails for these invoices directly from Stripe just like subscriptions.
Stripe has a newer API called Prices where you can create a price for any product and it can either be recurring or one-time. The easy part is existing Plans work with the Prices API by passing a Plan ID, but objects are returned in the slightly-different Prices API object format.
This commit is a refactor to the new API to handle the data in its new form, and lays the foundation for a one time payment plan to be added to any subscriptions product.
