Ruby on Rails: Google is not defined after render :new

Question

I'm using geocomplete to enter an address field of a #create form. Google map apis are loaded in the head.

<head>
    <script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?key=<%= ENV['DEV_MAPS_API_KEY'] %>&libraries=places">  </script>
</head>

Application.js.erb

$(document).ready(function(){
    $("#gig_location").geocomplete();
});

This works fine on page load, and if I refresh the page I don't have any problems either.

Problems arise if there are form errors. I am using render :new so inputted form fields are not lost, but as the page reloads I get the Uncaught ReferenceError: google is not defined error message.

Gig_controller.rb

  def create 
      .....code....
    if @gig.save
      redirect_to @gig
      flash[:success] = "Gig created successfully"
    else
      @errors = @gig.errors
      @gig = Gig.new(gig_params.merge(genres: genres))
      render :new
    end
   end

If I user redirect_to new_gig_path this reloads everything and geocomplete works, but form inputs are wiped also.

Other jquery elements keep working after render :new is called, it's only google map apis that don't.

How can I reload/save the google map api jquery upon rendering :new?

have you tried `$(window).on('load', function() { 'code'})` instead of `$(document).ready`? — SomeSchmo, Apr 28 '17 at 19:34

add below code to your new.html.erb:

$(document).ready(function(){
    $("#gig_location").geocomplete();
})

This does not work for me. It gives me the same ´google not defined´ error, but twice. – Rob Hughes Apr 28 '17 at 14:02

I have figured this out. render :new is actually calling the create [POST] action, not new.

My google map apis are loaded conditionally depending on the controller and action. Adding them to the gig#create action (not just gig#new) allows them to be loaded when render :new is called.

Maybe this will help someone that is having difficulties when using render :new.
