I also found this method on SO but the last line could be simplified by
passing from controller current_user.id or current_user.name instead of the
entire object
Application.js is not evaluated in the context of any session variables or
methods. The simplest way to access username from javascript would be to
set a cookie in a before_action on application controller:
class ApplicationController < ActionController::Base
before_action :set_user
private
def set_user
cookies[:username] = current_user.name || 'guest'
endend
Then from any js in app/assets you can access the cookie:
alert(document.cookie);
A more verbose but arguably cleaner method would be to create a route that
accesses the current user and returns the username e.g.
routes.rb
get 'current_user' => "users#current_user"
users_controller.rb
def current_user
render json: {name: current_user.name}end
application.js
$.get('/current_user', function(result){
alert(result.name);});
