I don't know why your monkey patch is showing one thing in the console and
something else in the server. However I suspect that the reason is the same
as why you are getting the type mismatch in the first place. I believe it
has to do with how the find_stations_near method is working. Since I don't
know how you wrote that method I had to assume that what you were doing was
getting a list of WeatherStation objects. If I just grab all the
WeatherStation objects in my DB, regardless of if they are WeatherStation or
NOAA type and run them through your map and PremiseWeatherStation.create
statements they work fine. Both server and console. I ran it again but this
time told it to return all NOAA objects instead of WeatherStation. It worked
without issue. What is the code for the method find_stations_near?
