@location in the show method of the locations controller will contain
the instance, but only after Hobo has had a chance to do that for you.
Here's a few possibilities. I think for you all three will work, but
for others the order might be important.
def show
hobo_show
@json = @location...
end
def show
hobo_show do
@json = @location...
end
end
def show
@location = find_instance
@json = ...
hobo_show
end
