YM4R_GM plugin...
This controller code works but clearly has limitations...
map_1 = GMarker.new([@salons[0].lat, @salons[0].lng])
@map.overlay_init(map_1)
but I really need this in a loop...
for salon in @salons do
map_id += 1
map_id_ = "map_id_" + map_id.to_s
map_id = Gmarker.new([salon.lat, salon.lng])
@map.overlay_init(map_id)
end
But inside the loop, I get the following error that I can't seem to
figure out a way to prevent...
NameError (uninitialized constant SalonsController::Gmarker):
How to use the Gmarker method inside a loop?

Ruby is case-sensitive. And that loop is rather sketchy... what you're
doing can just be replaced with something like
@salons.each {|salon| @map.overlay_init GMarker.new([salon.lat,
salon.lng])}
If you end up actually needing the array indices, each_with_index will
do nicely.
I don't think you're going to like this. I think the issue is that in
the for loop you need to capitalize the m in Gmarker (as in your
original code).
Also, ruby offers something called each with index. Your code could
become something like
@salons.each_with_index |salon, map_id|
map_id_ = "map_id_" + map_id.to_s
map_id = GMarker.new([salon.lat, salon.lng])
@map.overlay_init(map_id)
end
Hope that helps.
