Ruby On Rails Google Maps By Pete

An agile way to implement Google Maps geolocation in a Ruby On Rails scaffold

Ruby On Rails: 5, 6, 7

Add this line to your application's Gemfile:

gem 'google_maps_by_pete'

Go to your application's directory in Terminal and run the command:

bundle install

Let's create a example for a Place scaffold:

1. Let's create a new rails app:

rails new myapp

2. Create the database:

bundle exec rake db:create

3. Go to your application's directory in Terminal and run the command:

bundle exec rails g scaffold Place name:string description:text

4. Add this line to your application's Gemfile:

gem 'google_maps_by_pete'

5. Go to your application's directory in Terminal and run:

bundle install

6. Go to the application directory in Terminal and run the following command to install the necessary code and files from the gem:

bundle exec rake 'install_google_maps_by_pete[Place]'

7. Add jQuery to your layout file: /app/views/layouts/application.html.erb

<script src='/google_maps_by_pete/jquery-3.6.0.min.js'></script>

8. Add maps.css to your layout file: /app/views/layouts/application.html.erb

<link rel='stylesheet' href='/google_maps_by_pete/maps.css'>

9. Paste this partial to your _form.html.erb file: /app/views/places/_form.html.erb

<%= render 'shared/google_maps_by_pete', api_key: 'your_google_api_key',  height: '500px', center_map_on: {lat: 25.761681, lng: -80.191788}, model: place%>

10. Allow parameters (lat and lng) in your controller: /app/controllers/places_controller.rb

def place_params
   params.require(:place).permit(:name, :description, :lat, :lng)
end
