Project have some sub-apps:
app_core- (which has core fucntionalities of project.)app_order- (in which we store orders according to the user subscription.)app_subscription- (in which we can create subscriptions and user can subscribe a subscription after paying for it.)
Project has some constraints which we need to follow:
- user must have a subscription to create an order.
- user can have only one subscription at a time.
- subscription considered to be end, when
orderedfield is equal tocan_orderfield.
