Gmaps4rails is developped to simply create a Google Map:
-
directly from your model,
-
from your own json
It’s based on Ruby on Rails 3 Engines and uses Google Maps API V3.
See screencasts here: www.youtube.com/user/TheApneadiving
-
gem ‘gmaps4rails’ (in your gemfile, then bundle)
-
<%= yield :head %> (in your header)
-
<%= yield :scripts %> (in your footer)
-
config.serve_static_assets = true (in your production.rb), or run ‘rails generate gmaps4rails:install’ to copy the JS and CSS assets to your /public folder.
In your model, add:
acts_as_gmappable def gmaps4rails_address #describe how to retrieve the address from your model, if you use directly a db column, you can dry your code, see wiki “#{self.street}, #{self.city}, #{self.country}” end
Create a migration and add the following fields to your table (here users):
add_column :users, :latitude, :float #you can change the name, see wiki add_column :users, :longitude, :float #you can change the name, see wiki add_column :users, :gmaps, :boolean #not mandatory, see wiki
In your controller:
@json = User.all.to_gmaps4rails
In your view:
<%= gmaps4rails(@json) %>
Done!
