Rails Admin Map field

A simple gem to work with rails_admin that allow coordinate field update via a google map.

gem "rails_admin_map"

Then add an attr_accessor :coordinates to your active record model

class MyAwesomeModel < ActiveRecord::Base
  attr_accessor :coordinates
end

Then, add in your rails admin model initializer
config/initializers/rails_admin/modelName.rb

RailsAdmin.config do |config|
  config.model MyAwesomeModel do
    edit do
      field :coordinates, :map
    end
  end
end

After, add you google map api key(s) to the config/application.rb

# Map api key
config.map_api_key = 'YOUR_KEY_HERE'

# Map geocoding key (optional)
config.geo_api_key = 'YOUR_KEY_HERE'
