Google Maps for Rails (gmaps4rails)

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

When Gmaps4rails finally means Global Maps for Rails

I’ve added support for other map providers:

  • openlayers

  • mapquest

  • bing

See: github.com/apneadiving/Google-Maps-for-Rails/wiki/Map-Apis

Any help would be appreciated to complete this work.

Requirements

  • gem ‘gmaps4rails’ (in your gemfile, then bundle)

  • <%= yield :head %> (in your header)

  • <%= yield :scripts %> (in your footer)

To make Rails serve the assets (javascripts, stylesheets and marker images) you have several options, depending on your configuration and Rails version:

  • if you are using Rails 3.1 and have asset pipeline enabled (‘config.assets.enabled = true’ in config/application.rb), include the appropriate manifest:

    • //= require gmaps4rails/bing.js

    • //= require gmaps4rails/googlemaps.js

    • //= require gmaps4rails/mapquest.js

    • //= require gmaps4rails/openlayers.js

    • //= require gmaps4rails/all_apis.js

    You even don’t need the ‘yield :head` if you include `require gmaps4rails` in your CSS manifest.

  • if you are using Rails 3.0: if you have Rails configured to serve static assets (‘config.serve_static_assets = true’; note that it is disabled by default in production environment), they’ll be served directly from gem’s public/ directory.

  • finally you can just copy assets to your application’s public/stylesheets, public/javascripts/gmaps4rails and public/images. It’s recommended to do this in production so that you can let your webserver serve them rather than go through Rails each time they are requested. There’s a generator to help you with that:

    rails generate gmaps4rails:install
    

Basic configuration

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

How to?

QuickStart!

In your controller:

@json = User.all.to_gmaps4rails

In your view:

<%= gmaps4rails(@json) %>

Done!

Options

  • Markers with Info window, Custom Picture, RichMarkers (make your own markers with custom html)

  • Automatic sidebar with list of markers

  • Circles, Polylines, Polygons

  • Geocode directly your address and retrieve coordinates.

  • Wrapper for ‘Direction’, giving instructions to go from point A to point B

  • Auto-adjust the map to your markers

  • Refresh your map on the fly with Javascript (and Ajax)

  • KML support

  • Easy multimap
