Hi. I've been trying to play with this for a while now but I haven't seemed to get it to work. I have a admin controller, which is scaffolded, to input the lat and long along with info. I have a restaurant controller that will display the map with the points. I can get the map to show but the points do not show. -
class CreateRestaurants < ActiveRecord::Migration
-
def self.up
-
create_table :restaurants do |t|
-
t.column :category, :string
-
t.column :name, :string
-
t.column :address, :string
-
t.column :phone, :string
-
t.column :hours, :text
-
t.column :more_info, :text
-
t.column :latitude, :float
-
t.column :longitude, :float
-
end
-
end
-
-
def self.down
-
drop_table :restaurants
-
end
-
end
-
-
class RestaurantController < ApplicationController
-
-
def map
-
@restaurants = Restaurant.find :all
-
end
