where to put logic

Folks
  Quick question, i know db model logic goes into the model and how the
views are interacted with goes into the controller code. And how the
page looks goes into the view code with rails. But lets say i have a
system call that shells out and runs a command that populates an array
with a list of devices that i want to show in a select box in my view.
Where would i put this type of system call at? Not sure if this goes
into the controller or if this should be called from the view using a
helper method, or should this go into the model. i know for long
running external tasks i should use somthin like sidekiq but this an
external call and is not expensive. so where is the best place to do
things that happen from external calls and do not directly relate to the
mvc? any advice would be helpfull thanks.

Remember you can have models that are not derived from ActiveRecord so
you could have a class to handle your external calls.
