Hi Gugg,
Chances are you aren't converted it to JSON correctly. The outputted JSON
has to look like this:
"picture":"/assets/dayhome.png","width":32,"height":37,"lat":53.5402,"lng":-113.628
Here's snippet of the code I'm using (use it in your controller):
def gmap_prepare_homes(homes)
homes.to_gmaps4rails do |home, marker|
marker.title home.name
marker.picture({ :picture => "/assets/dayhome.png",
:width => 32,
:height => 37
})
end
end
I don't actually use the built in method gmaps4rails_marker_picture which
might be outputting the strings (and it looks like it does, here:
http://rubydoc.info/gems/gmaps4rails/0.7.5/Gmaps4rails/ActsAsGmappable/InstanceMethods
)
If the numbers are in quotes you're going to have a bad time :(.
