application.html.erb where line #6 raised: TypeError: Ruby on rails

I'm facing the following error message:

ExecJS::ProgramError in Restaurantes#index Showing C:/rubyProject/vota_prato/app/views/layouts/application.html.erb where >line #6 raised:

TypeError: O objeto não dá suporte para a propriedade ou método Rails.root: C:/rubyProject/vota_prato

Application Trace | Framework Trace | Full Trace app/views/layouts/application.html.erb:6:in >`_app_views_layouts_application_html_erb__971963449_62998908' Request

I fixed it removing the line:

true %>

from my app/views/layouts/application.html.erb file

after I did it, I faced the other problem =(. I created a action destroy at one controller:

class RestaurantesController < ApplicationController
    def destroy
        @restaurante = Restaurante.find(params[:id])
        @restaurante.destroy
        redirect_to(action: "index")
    end

    def index
        @restaurantes = Restaurante.all
    end

    def show
        @restaurante = Restaurante.find(params[:id])
    end
end

and my index.html.rb file:

<h1>Listagem de Restaurantes</h1>

<table>
  <tr>
    <th>ID</th>
    <th>Nome</th>
    <th>Endereço</th>
    <th>Especialidade</th>
  </tr>

<% @restaurantes.each do |restaurante| %>
  <tr>
    <td><%= restaurante.id %></td>
    <td><%= restaurante.nome %></td>
    <td><%= restaurante.endereco %></td>
    <td><%= restaurante.especialidade %></td>
    <td><%= link_to 'Mostrar', action: 'show', id: restaurante %></td>
    <td>--</td>
    <td><%= link_to 'Deletar', {action: 'destroy', id: restaurante},{method: "delete"} %></td>
  </tr>
<% end %>
</table>

when clicked at Deletar link, it executed same action as Show action, I don't know why

You need to install nodejs to fuse the turbolliks; )

Follow the link: https://nodejs.org/en/download/

First of all, I'm sorry for my english if it's too bad... This error happened to me a couple months ago. There wasn't a problem with ruby, rails gem, or any other gem installed.

These are my specs:

  • Running Windows 10
  • Using RubyInstaller 3.2.0, packages included are:
    • Ruby 2.2.4
    • Rails 4.2
    • Bundler
    • Git
    • Sqlite
    • TinyTDS
    • SQL Server Support
    • DevKit

After insalling the RubyInstaller, I created a new project, but I had the same error like you:

ExecJS::ProgramError in home#index Showing C:/ruby_project/app/views/layouts/application.html.erb where line #6 raised:
TypeError: Object doesn't support this property or method

DEFINITE SOLUTION IS:

  1. Stop any rails web server.
  2. Close everything.
  3. Open your web browser and surf onto nodejs download packages site OR you can download it from here: Download Link (Windows)
  4. Install nodejs on your Operative System. Install the 32-bit version, even if you're running on 64-bit.
  5. Restart your computer, open a command line to your desired project, and then run 'rails server'.
  6. Done... Don't need to change anything on app/views/layouts/application.html.erb. IT WILL WORK... just let it by default:

<!DOCTYPE html>
<html>
<head>
  <title>Sample</title>
  <%= stylesheet_link_tag    'application', media: 'all', 'data-turbolinks-track' => true %>
  <%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>
  <%= csrf_meta_tags %>
</head>
<body>

<%= yield %>

</body>
</html>

NOTE: For linux/mac users, just install ruby and rails by RVM (Ruby Version Manager). You won't have any problem, I tell you this by experience.

For installing RVM on your linux/mac terminal I will recommend you these tutorials below. I've tried them and they work!

Please comment if this worked for you or not...

Regards.

To solve the ExecJS problem in Windows, change the parameter application to default in lines 5 and 6 of the views/layouts/aplication.html.erb file.

The file should look like this:

<%= stylesheet_link_tag    'default', media: 'all', 'data-turbolinks-track' => true %>
<%= javascript_include_tag 'default', 'data-turbolinks-track' => true %>

This worked for me.

Thanks, it works, but I think it worked because I installed the nodeJS. After I restarted my computer, however both solutions worked

Can't tell much about your JS problem because not enough information.

As for the link part, your delete link should look like this:

<%= link_to 'Deletar', restaurante_path(restaurante), method: :delete %>

Also make sure that you have jquery-ujs included in your application.js (this is what understands the method: :delete part in your link and POSTs a form rather than GETting a page)

BTW, do not ask two question in one. Make them separate questions.

Have you uncommented the line:

gem 'therubyracer',  platforms: :ruby

from your gemfile? Do that, run "bundle install" and try again. The delete method relies on some Javascript. It's rubyracer or some nodejs thing you can use instead, I can't remoember what it is called.
