TR-181 Mapping: Merge GPV Response into Store

Setup

Mix.install([
  {:caretaker, path: "."}
])

alias Caretaker.CWMP.SOAP
require Logger

if Process.whereis(Caretaker.TR181.Store) == nil do
  {:ok, _} = Caretaker.TR181.Store.start_link([])
end

Decode GetParameterValuesResponse from fixture

xml = File.read!("test/fixtures/tr069/get_parameter_values_response.xml")

{:ok, %{body: %{rpc: "GetParameterValuesResponse", xml: body_xml}}} =
  SOAP.decode_envelope(xml)

{:ok, data} = Caretaker.TR069.RPC.GetParameterValuesResponse.decode(body_xml)
Logger.info("Decoded #{length(data.parameters)} parameters from GPV response")

Merge into TR-181 Store and inspect

dev_key = {"A1B2C3", "Router", "XYZ123"}

:ok =
  Caretaker.TR181.Store.merge_params(
    dev_key,
    data.parameters,
    Caretaker.TR181.Schema.default()
  )

model = Caretaker.TR181.Store.get(dev_key)

manuf = get_in(model, ["Device", "DeviceInfo", "Manufacturer"]) ||
        get_in(model, ["Device.DeviceInfo.Manufacturer"]) # depending on shape

Logger.info("Manufacturer=#{inspect(manuf)}")
%{manufacturer: manuf, param_count: length(data.parameters)}
