• Rails Admin Map Field
• RailsAdminGoogleMap
• Rails Admin Place Field

Installation

Add this line to your application's Gemfile:

gem 'rails_admin_yamap_field'

And then execute:

Usage

Add attr_accessor ya_map to you model for which you need to show the map or define ya_map and ya_map= methods as you wish, for example:

class Address < ApplicationRecord
  # others methods
  def ya_map=(lat_lon)
    self[:lat], self[:lon] = lat_lon.split(",")
  end
  def ya_map
    [lat, lon].join(",")
  end
  # others methods
end

Available options for configure in rails_admin:

• center_lat - map center latitude
• center_long - map center longitude
• zoom_level - map zoom level
• map_html_width - width div map container: default '100%'
• map_html_height - height div map container: default '500px'
• map_lang - language map: default 'ru_RU', for other values see this ref
• api_key - api key for enterprise version: default 'nil'
• latitude_field - latitude attribute name in you model: default 'latitude'
• longitude_field - longitude attribute name in you model: default 'longitude'

Example:

class Address < ApplicationRecord
  attr_accessor :ya_map

  rails_admin do
    field :lat, :hidden
    field :lon, :hidden
    field :ya_map, :yamap_field do
