# SolidusSubscriptions
[](https://circleci.com/gh/solidusio-contrib/solidus_subscriptions/tree/master)
A Solidus extension to add subscriptions to your store.
## Installation
Add solidus_subscriptions to your Gemfile:
```ruby
gem 'solidus_subscriptions', github: 'solidusio-contrib/solidus_subscriptions'
```
Bundle your dependencies and run the installation generator:
```shell
bundle
bundle exec rails g solidus_subscriptions:install
```
### Guest checkout
Subscriptions require a user to be present to allow them to be managed after they are purchased.
Because of this, you must disable guest checkout for orders which contain `subscription_line_items`.
An example would be adding this to the registration page:
```erb
<%# spree/checkout/registration.html.erb %>
<% if Spree::Config[:allow_guest_checkout] && current_order.subscription_line_items.empty? %>
```
This allows guests to add subscriptions to their carts as guests, but forces them to login or create
an account before purchasing them.
## Usage
### Purchasing subscriptions
By default, only Spree::Variants can be subscribed to. To subscribe to a variant, it must have the
`subscribable` attribute set to true.
To subscribe to a variant, include the following parameters when posting to `/orders/populate`:
```json5
{
// other add to cart params
subscription_line_item: {
quantity: 2, // number of units in each subscription order
subscribable_id: 1234, // which variant the subscription is for
interval_length: 1, // time between subscription activations
interval_units: "month", // plural qualifier for length (day/week/month/year)
end_date: '2011/12/13' // stop processing after this date (use null to process ad nauseam)
}
}
```
This will associate a `SolidusSubscriptions::LineItem` to the line item being added to the cart.
The customer will not be charged for the subscription until it is processed. The subscription line
items should be shown to the user on the cart page by looping over
`Spree::Order#subscription_line_items`. `SolidusSubscriptions::LineItem#dummy_line_item` may be
useful to help you display the subscription line item with your existing cart infrastructure.
When the order is finalized, a `SolidusSubscriptions::Subscription` will be created for each group
of subscription line items which can be fulfilled by a single subscription.
#### Example
An order is finalized and has the following associated subscription line items:
1. `{ subscribable_id: 1, interval_length: 1, interval_units: "month" }`
2. `{ subscribable_id: 2, interval_length: 1, interval_units: "month" }`
3. `{ subscribable_id: 1, interval_length: 2, interval_units: "month" }`
This will generate 2 subscriptions: the first related to subscription line items 1 and 2, and the
second related to subscription line item 3.
### Processing subscriptions
To process actionable subscriptions simply run:
```bash
$ bundle exec rake solidus_subscriptions:process
```
The task creates ActiveJob jobs which can be fulfilled by your queue library of choice.
We suggest using the [Whenever](https://github.com/javan/whenever) gem to schedule the task.
### API documentation
You can find the API documentation [here](https://stoplight.io/p/docs/gh/solidusio-contrib/solidus_subscriptions?group=master).
## Development
### Testing the extension
First bundle your dependencies, then run `bin/rake`. `bin/rake` will default to building the dummy
app if it does not exist, then it will run specs. The dummy app can be regenerated by using
`bin/rake extension:test_app`.
```shell
bundle
bin/rake
```
To run [Rubocop](https://github.com/bbatsov/rubocop) static code analysis run
```shell
bundle exec rubocop
```
When testing your application's integration with this extension you may use its factories.
Simply add this require statement to your spec_helper:
```ruby
require 'solidus_subscriptions/factories'
```
### Running the sandbox
To run this extension in a sandboxed Solidus application, you can run `bin/sandbox`. The path for
the sandbox app is `./sandbox` and `bin/rails` will forward any Rails commands to
`sandbox/bin/rails`.
Here's an example:
```shell
$ bin/rails server
=> Booting Puma
=> Rails 6.0.2.1 application starting in development
* Listening on tcp://127.0.0.1:3000
Use Ctrl-C to stop
```
### Releasing new versions
Your new extension version can be released using `gem-release` like this:
```shell
bundle exec gem bump -v VERSION --tag --push --remote upstream && gem release
```
