In this tutorial we'll talk about how to use Google Maps API with Rails. We'll see some examples of using Static API and Javascript API, how to place a marker and how to update the marker position when we change a form input value. And finally how to update the input value by dragging the marker. All of this without using any gems.

Level: beginner

Pre requisites: basic knowledge of Rails and Javascript
