RailsAdminGoogleMap

Implementation of user friendly google map field in rails_admin. Any suggestions are welcome.

TODO

• Test with multiple google map field within the same model
• More Google map options

Installation

Add this line to your application's Gemfile:

gem 'rails_admin_google_map'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rails_admin_google_map

Usage

Strategy: using a serialized field to store all google map data. We store all datas return

Migration example:

def change
  add_column :users, :google_map, :text
end

In your model:

class User < ActiveRecord::Base
  serialize :google_map, JSON
end

RailsAdmin configuration

RailsAdmin.config do |config|
  config.model Point do
    edit do
      field :google_map, :google_map do
        google_api_key 'APIKEY'
        default_latitude -34.0
        default_longitude 151.0
        locale 'en'
      end
    end
  end
end

Example of JSON stored values, everything is build dynamically and depends on Google return.

{
  "location":{
      "latitude":45.5016889,
      "longitude":-73.56725599999999
   },
   "formatted_address":"Montréal, QC, Canada",
   "locality":"Montréal",
   "political":"Canada",
   "administrative_area_level_3":"Pointe-Calumet",
   "administrative_area_level_2":"Communauté-Urbaine-de-Montréal",
   "administrative_area_level_1":"Québec",
   "country":"Canada"
}

Example of usage in a view

<%= u.google_map['location']['latitude'] %>
<%= u.google_map['country'] %>
<%= u.google_map['formatted_address'] %>
