Problems in Ruby first app

[Alvaro Naves]

Hi, I´m iniciating in Ruby. 

After instalattion ( Ruby and DevKit ) and trying to run a simple example: 

When I use localhost:3000/test I get a page not found; 

When I use localhost:3000/test.js the browser can find ONLY the first page. No navigation, like trying to insert data on the first row. 

Can anyone help me ? 

Tks in advance.

Ruby is not Rails. What tutorial are you following?

Yes, Ruby is not Rails. 

I can get the welcome page from RubyOnRails with localhost:3000. 

One step ahead, when I try an app using scaffold, rake db:migrate and so on, when I type localhost:3000/app  I got an error. ( the same ) If I type localhost:3000/app.js the app first page is ok, but can´t navigate on it..

I´ve been looking in the internet for Ruby first app or some like that and tryed several..

Some suggestion for a simple app ? 

Tks

Again, what tutorial are you trying?

I'm asking because your URLs are not the expected URLs for a scaffold. A good tutorial will tell you that if you run scaffold, the URL would be plural because you're creating a RESTful resource. Therefore, "rails generate scaffold app field1 field2" will give you a route at localhost:3000/apps.

Also, I tried replicating your problem in the latest version of Rails (4.2). I didn't get a "page not found", I got a "No route matches [GET] /app". localhost:3000/apps and localhost:3000/apps.js work just fine.

What do you mean by "can find ONLY the first page"? Is there a "New App" link that isn't working? Or is it a different looking page from the screenshot in the tutorial you're following?

Ok Bryen. 

You are right about the name of app. I tryed localhost:3000/app1s. 

The return I got: 

No route matches [GET] "/app1s"

Can you help me ?

The table below the error should tell you what paths/routes are available.

For example:

The apps_path "/apps(.:format)" entry means that the "localhost:3000/apps" path is available. Same goes with  "/apps/new(.:format)" (localhost:3000/apps/new), "/apps/:id(.:format)" (localhost:3000/apps/[id]), and "/apps/:id/edit(.:format)" (localhost:3000/apps/[id]).

Hi Bryan. 

Now I can show "Hello World" page with localhost:3000. 

I had to change routes.rd: 

  # You can have the root of your site routed with "root"

  root 'home#index'

I had to change Index.html.erb

<h1>Hello World !</h1> 

and aplication.html.erb

....

  <title>Blog</title>

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

  <%= javascript_include_tag 'default', 'data-turbolinks-track' => true %>

  <%= csrf_meta_tags %>

....

It was hard to find it all. 

The Tutorial with code examples I´m using is Guides.RubyonRails.org. Could you suggest me another one ? 

Thanks for your attention.  

Regards
