This application consists of a contact list which will be shown on a map.

Initial CRUD App

Shell commands (You may execute the whole script in one go):

echo Create new rails structure
rails new Gmaps4Rails	
cd Gmaps4Rails

pause Create scaffold for the people model and migrate the database
rails g scaffold contact firstname:string lastname:string address:string zip:string city:string country:string
rake db:migrate

open http://localhost:3000/contacts
say Please reload your web browser in a few moments &
rails server
echo Done :-)

Adding gmaps4rails specific things

Shell commands

# Add the the gem to the Gemfile and use the bundle command to install it
echo "gem 'gmaps4rails'" >> Gemfile                                        
bundle install                                                         

# Run the provided gmaps4rails generator
rails generate gmaps4rails:install

Migrate the contact model to have the required parameters

rails g migration AddLongLatToContacts latitude:float longitude:float gmaps:boolean
rake db:migrate

Change the model contact.rb to this:

class Contact < ActiveRecord::Base

    attr_accessible :firstname, :lastname, :address, :zip, :city, :country

	acts_as_gmappable 

	def gmaps4rails_address
		"#{self.address}, #{self.zip} #{self.city}, #{self.country}"
	end

end

Change the body part of your layout as follows

<body>
<%= yield :head %>
<%= yield %>
<%= yield :scripts %>
</body>

Add a new action to your contacts_controller.rb:

def map
   @json = Contact.all.to_gmaps4rails
end

Add a new file map.html.erb to the contact's view directory and add the following line to it:

<%= gmaps4rails(@json) %>

Now we create a new custom route to our routes.rb by adding the following line:

match 'map' => "contacts#map"

Now we need to add a few contacts which then magically appear on our map.
