如何在Rails控制器中替换嵌入式JavaScript

Question

My existing sessions_controller use inline javascript exit to root_path as follow:

render inline: "<script>window.location.replace('#{url}')</script>"

It worked in Rails 4 but not in Rails 5. Most document talking about calling javascript in view. But this is controller. From what I understand I should replace with

render :js => "myNewJavascriptFunction();"

Which I did tried create myNewJavascriptFunction() in another file eg: views/sessions/create.js.erb it has error

undefined method `myNewJavascriptFunction' for

Help:

1. How or Should I put the javascript in views/sessions/create.js.erb
2. Can we put the javascript in assets to work with controller and how.

Here my existing codes: In SessionsController

  def create
    auth = request.env["omniauth.auth"]
    user = User.from_omniauth(auth)
    session[:user_id] = user.id
    if params.permit[:remember_me]
      cookies.permanent[:auth_token] = user.auth_token
    else
      cookies[:auth_token] = user.auth_token
    end
        # render :js => refresh(root_path) #not work
        # redirect_to root_path            #not work with JQM
        render inline: "<script>window.location.replace('#{url}')</script>" #not work with Rails 5
    rescue 

    render inline: "<script>window.location.replace('#{url}')</script>" #not work with Rails 5
  end

views/sessions/create.js.erb

function refresh(url='/') {
  window.location.replace(\'#{url}\');
}

menu call

- if login?
  %li
    %a{"data-panel" => "main", :href => logout_path, "data-ajax"=>"false"} Sign Out
- else
  %li
    %a{:href=>new_session_path, "data-panel" => "main"} Sign In
  %li
    %a{:href=>new_identity_path, "data-panel" => "main"} Sign Up
%li
  = link_to "Refresh", "#", :onclick=>"window.location.replace('/')"
- if !login?    
  = link_to image_tag( 'facebook-sign-in-button.png'), '/auth/facebook', rel: "external"

No need to have a views/sessions/create.js.erb

Just replace render inline: "<script>window.location.replace('#{url}')</script>" with render js: "window.location.replace('#{url}')"
