How to include js script only once?

Question

Ruby on Rails

I have a multilingual application. The problem is - as soon as I go to the page with locations - everything is fine. But if I want to change the language -
<%= link_to image_tag('en.png'), locale: 'en' %>
Then they write to me that it is impossible to connect the google maps api several times - You have included the Google Maps API multiple times on this page. I tried to connect this script both in my specific page and in application.js - The result is the same - the same error.
There was a thought - first initialize the variable with zero and increment this variable for each click, and if this variable is not zero, then do not connect the script with google maps. But I could not pull out a variable from js in view. This is real?
Thanks everyone for the replies.

If Turbolinks is used, Evaluting script tags might help . Turbolinks keeps a cache of pages and doesn't always execute scripts in an obvious way. For some pages, it can be turned off altogether.
