PimsPlay

TODO: Add description

Installation

If available in Hex, the package can be installed by adding pims_play to your list of dependencies in mix.exs:

def deps do
  [
    {:pims_play, "~> 0.1.0"}
  ]
end

Documentation can be generated with ExDoc and published on HexDocs. Once published, the docs can be found at https://hexdocs.pm/pims_play.

There is a queue of visit_pims_id. This queue is a cache (@ezyvet_invoice_queue) (what puts data in here)
The scheduler runs this task every 10 seconds Instinct.Scheduler.Task.EzyVetInvoice.run() Instinct.PIMS.process_ezyvet_invoice() Source.EzyVet.Sync.PVL.run()
THis will get 1 visit_pims_id out of the queue and call maybe_refresh_pvl If the queue is empty, it will refill the queue by re-fetching the list of visit_pims_ids
maybe_refresh_pvl will check the timestamp of the pvl data for that visit_id If it is expired, it will refresh it from the API. Otherwise it uses the cached version if it exists.
Refreshing the pvl for a visit will get all line items for that appointment.

THis runs every 2 minutes.
It runs process_checkins() and process_checkouts()
THis will get the list of visits from the PIMS and create the visits in ITP if it doesn't exist

Maintain a list of active visit_ids in state
API functions to add and delete visi_ids. These willbe called during checkin/chckout
Use cache to store the retrived pvl line_items
A new visit should send a message to the PIMS API to fetch that PVL
We should look at the age of each cacahe item and refresh when it reaches a certain age. We could poll or store a settimeout function that does t automatically.

Could we do something like this: https://stackoverflow.com/questions/43892784/what-are-the-equivalent-of-settimeout-and-setinterval-in-elixir
