application.css / application.js doesn't work on rails 3.1

Question

I start to study Rails 3.1. However, css doesn't work.

There are some scss in app/assets/stylesheets/, but they don't appear in application.css

I create productshoge.css(not scss) but it doesn't work either.

I think "that'll automatically include all the stylesheets available in this directory" , but any css doesn't be included.

when I try to re-make new application ( rails new XXX), I met same situation.

would someone advise me?

folders
app/assets/stylesheets/
├── application.css
├── carts.css.scss
├── layout.css.scss
├── line_items.css.scss
├── products.css.scss
├── productshoge.css
├── scaffolds.css.scss
└── store.css.scss

Solution

Just update the rails version in the Gemfile to 3.2.13 and run bundle update. Also you should remove *= require productshoge.css from application.css

I hope this will help you.

OTHER TIPS

Please be sure that you have included that line in /app/views/layouts/application.html.erb

<%= stylesheet_link_tag    "application", :media => "all" %>
  <%= javascript_include_tag "application" %>

You have to include CSS manually like,

app/assets/stylesheets/

* require carts
* require layout
* require line_items
* require products
* require productshoge
* require scaffolds
* require store
