I want to retrieve the list max_sell_order from the function below in MyApp.WorkA
def handle_info(:sell_order_fetch, state) do
data = sell_order()
|> Enum.sort_by(&(Map.get(&1, "price")), &>=/2)
|> get_sell_head
max_sell_order = data
schedule_sell_order_fetch
{:noreply, Map.put(state, :max_sell_order, max_sell_order)}
end
and use it in another function in another module for some calculations. example
require MyApp.FunctionA
def new_function(max_sell_order) do: IO.inspect(max_sell_order)
But I keep getting undefined function max_sell_order.
Please, how can I call and use the list from another module inside another module?

The above statement is equivalent to
{:noreply, state}, i.e.stateis a Map where one of the keys ismax_sell_order:and the value is the “max sell order data”.stateis managed as part of the running process - it is not part of the module.So the only way you can provide the
max_sell_orderto another module is by calling the module function directly. So ultimately some code inside one of the process handlers (e.g.handle_whatever) or one of the functions called by a handler there will be something like:
