README

Family module is an extension to Subscriptions module providing parent/child relation between subscriptions. Parent subscription is able to trigger generation of child subscriptions via family_requests.

WARNING: Module is close-to-production quality, but expect some major breaking changes in the future (e.g. dropping of redundant tables, changing master/slave names).

Installation

Add remp/crm-family-module via repository or package to your composer.json file and install it to your CRM skeleton.

Enable installed extension in your app/config/config.neon file:

extensions:
	# ...
	- Crm\FamilyModule\DI\FamilyModuleExtension

Usage

Family module needs to know which subscription types are meant to be parents and what subscription types should the child subscriptions have.

To do that, please seed the relations via FamilySubscriptionTypesRepository::add() method:

• donationMethod. Available values are:
  • copy: Child subscriptions will copy start/end date of its parent.
  • fixed_days: Child subscriptions will start at the time of activation and last fixed amount of days (implementation is currently not available).
• count. Number of child subscriptions to create when parent subscription is created.
• is_paid. Indicator used to flag whether child subscriptions should be counted as paid or not.

Anytime new master subscription is created, handler will create requests with codes that can be shared with other users so they can activate their access.

These codes can be accessed via two channels:

• As activation URLs in customer zone. You can enable the default widget in your own module by attaching following widget to the placeholder:

  namespace Crm\DemoModule;
  
  class DemoModule
  {
      public function registerLazyWidgets(\Crm\ApplicationModule\Widget\LazyWidgetManagerInterface $lazyWidgetManager) {
          $lazyWidgetManager->registerWidget(
              'frontend.subscriptions.top',
              \Crm\FamilyModule\Components\FamilyRequestsListWidget\FamilyRequestsListWidget::class,
              300
          );
      }
  }

• As family codes via API. You can access all available family codes with parent's account token via /api/v1/family/list API. These codes can be then activated via /api/v1/family/activate API.

ExtendFamilyExtension

You can use ExtendFamilyExtension subscription type extension method to extend your family/company subscriptions.

If CRM is creating new subscription with subscription type with this extension method, it tries to find all actual family subscriptions. If there is one, new subscription is appended after the actual. Otherwise the new subscription starts immediately (ignoring other non-family subscriptions).

The extension is registered automatically. If FamilyModule is enabled, you should be able to select it in your subscription type form.

Renewal of child subscriptions

If the parent user account renews family/company subscription and new subscription starts at the same time as the previous one ends, child accounts are given new (renewed) subscriptions too. It's done automatically by event handler \Crm\FamilyModule\Events\NewSubscriptionHandler.

This time gap between subscriptions can be configured within your main config. For example if you want to allow renewal only 7 days after end of the subscription:

services:
	# ...
	familyNewSubscriptionHandler:
		setup:
			- setSubscriptionsTimeGap('7 days')

You can also prevent copying activated family requests at all, by adding meta keep_requests_unactivated=1 to payment meta table.

Dynamic count of child subscriptions

If you don't want to have static count of generated child subscriptions defined within family_subscription_types.count, you can set your family subscription's value count to 0 and define number of child subscriptions to generate within payment item count. Conditions:

• Type of payment item is \Crm\SubscriptionsModule\PaymentItem\SubscriptionTypePaymentItem::TYPE.
• Subscription type of payment item is family subscription type which is defined within family_subscription_types table with value 0.
• Payment item count is non zero.

Example of payment item set while creating payment from within admin interface:

In this case, handler \Crm\FamilyModule\Events\NewSubscriptionHandler generates 7 child subscriptions.

Custom type and count of child subscriptions

If you want to have opportunity to define own combination of subscription types and their count you can do it by creating customizable subscription type with following steps:

• Define payment items for master subscription as \Crm\SubscriptionsModule\PaymentItem\SubscriptionTypePaymentItem::TYPE which will represent slave subscription types.
• Payment items must have meta (payment_item_meta) information with key subscription_type_item_id and value that refer to slave subscription type.
• Create family subscription type (family_subscription_types) with master subscription and previously defined and slave subscription type let null.

Admin interface in case of customizable subscription types is selected handles differently - display additional options for subscription type count and price.

Example of creating the payment of family subscription with customizable subscription type:

By the creating of payment for family subscriptions the payment items are created according counts and prices entered in admin form. In this case, handler \Crm\FamilyModule\Events\NewSubscriptionHandler generates 6 child subscriptions (5 of WEB type and 1 of KLUB type).

API documentation

All examples use http://crm.press as a base domain. Please change the host to the one you use before executing the examples.

All examples use XXX as a default value for authorization token, please replace it with the real tokens:

• API tokens. Standard API keys for server-server communication. It identifies the calling application as a whole. They can be generated in CRM Admin (/api/api-tokens-admin/) and each API key has to be whitelisted to access specific API endpoints. By default the API key has access to no endpoint.
• User tokens. Generated for each user during the login process, token identify single user when communicating between different parts of the system. The token can be read:
  • From n_token cookie if the user was logged in via CRM.
  • From the response of /api/v1/users/login endpoint - you're free to store the response into your own cookie/local storage/session.

API responses can contain following HTTP codes:

If possible, the response includes application/json encoded payload with message explaining the error further.

Work in progress...

Fixed days child subscriptions. Sometimes you might want to allow your users to generate child subscriptions independent of the master subscription that will last fixed amount of days. We plan to work on the implementation allowing to specify this in the family_subscription_types.

Dynamic count of child subscriptions. This will allow the ability to use single parent-child relation to generate dynamic number of child subscriptions based on a setting of parent subscription.
