Ok so compiling my assets is working fine but when I run:
thin start -e production
none of my javascript or css is loading. My browser is also cancelling the requests to get my assets. I'm not sure why this is but I suspect its because it thinks its 404'ing on them. If you look at the top image you'll see that my application.css file was compiled and stored in my assets folder but when I try to access the file, I'm getting my 404.html file.
What gives!?
Edit:
I was asked to post my view. Here is some of the code in the project:
<% content_for :title, 'Quick Quote' %>
<% content_for :subtotal, get_subtotal %>
<% content_for :stylesheet_includes do %>
<%= stylesheet_link_tag "quote", "jquery-ui-timepicker-addon" %>
<% end %>
<% if #quote.errors.any? %>
<div class="flash alert">
<% #quote.errors.full_messages.each do |msg| %>
<div><%= msg %></div>
<% end %>
</div>
<% end %>
<h1>Quick Quote</h1>
my layout:
<!DOCTYPE html>
<html>
<head>
<title><%= (yield(:title) + " - " unless yield(:title).blank?).to_s + "Online Scheduler Order Taker" %></title>
<%= stylesheet_link_tag "application", "jquery-ui-timepicker-addon.css", :media => "all" %>
<%= yield :stylesheet_includes %>
<%= javascript_include_tag "application" %>
<%= yield :javascript_includes %>

Check your config/environments/production.rb file and add next line to it (if it does not have it yet):
config.serve_static_assets = true
Rails recommends that this setting config.serve_static_assets by default should be disabled i.e. set to false. Here is the default configuration in config/environments/production.rb generated in rails app
Disable Rails's static asset server (Apache or nginx will already do this)
config.serve_static_assets = false
So if you are setting it to true in your local app then that's still fine. But if you are deploying your app on Apache or ngix or anything other than heroku then its not advisable to make config.serve_static_assets=true in your production.rb config file. Here is the documentation in Rails guides.
config.serve_static_files configures Rails itself to serve static
files. Defaults to true, but in the production environment is turned
off as the server software (e.g. NGINX or Apache) used to run the
application should serve static assets instead. Unlike the default
setting set this to true when running (absolutely not recommended!) or
testing your app in production mode using WEBrick. Otherwise you won't
be able use page caching and requests for files that exist regularly
under the public directory will anyway hit your Rails app.

Rails 5:
Change config.public_file_server.enabled in production.rb to true or add RAILS_SERVE_STATIC_FILES with any value to env variables.

Can you put this line in your current environment.rb?

In my application, I have many controllers and tons of css which could potentially be conflicting if plopped all together. Because of this I am linking my stylesheets on a controller-to-controller basis. The Ruby on Rails Guides suggests the following:
You can also opt to include controller specific stylesheets and JavaScript files only in their respective controllers using the following:
%= javascript_include_tag params[:controller] %> or <%= stylesheet_link_tag
params[:controller] %>
(I had to omit the first < from <%= because of Stack Overflow block quotes.)
Therefore, here is the resulting head of my application.html.erb file:
<%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>
<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track' => true %>
<%= javascript_include_tag params[:controller] %>
<%= stylesheet_link_tag params[:controller] %>
I have shared css for a navigation bar, which is #import[ed] in my application.css file, and that always works fine. The navigation bar is always styled properly.
The problem is, when I visit a specific page, on the first page request, the relevant css to that controller isn't loaded. And in the logs, a request is never made for the controller's stylesheets. But on the second page request, it gets styled, and the logs reveal that the stylesheets were requested.
Any reason why this is?
Below is some relevant code to this issue:
/*
* This is a manifest file that'll be compiled into application.css, which will include all the files
* listed below.
*
* Any CSS and SCSS file within this directory, lib/assets/stylesheets, vendor/assets/stylesheets,

And in my config/initializers/assets.rb I added all of the names of my javascript and css files to the line
Rails.application.config.assets.precompile += ......
If you are not using Turbolinks, remove it from your project. It includes:
removing turbolinks gem
removing requires from application.js and application.css
removing data-turbolinks-track attribute from your layout
And consider using rails new --skip-turbolinks for your next project.
I'm running the latest version of Thin, Rails, and Ruby. The relevant parts of my build script are:
export RAILS_ENV=production
export RAILS_SERVE_STATIC_FILES=true
# generate static assets
RAILS_ENV=production rake assets:precompile
# restart server
rails server thin -d
And in my production.rb I have
config.serve_static_files = ENV['RAILS_SERVE_STATIC_FILES'].present?
And I include these files in my view using
<%= stylesheet_link_tag 'application', media: 'all' %>
<%= javascript_include_tag 'application' %>
This successfully compiles my assets and moves them to the /public/assets folder. However, none of these assets are actually served when loading the page. The generated HTML is
<link rel="stylesheet" media="all" href="/stylesheets/application.css" />
<script src="/javascripts/application.js"></script>
These don't have the digests included in the filename, so I believe they're incorrect. Attempting to manually load the filenames both with and without their digest included all fail with a 404 as well. What am I doing wrong?
put the js files under app/assets/javascript.
put the css files under app/assets/stylesheets.
All your js and css files are loaded in the header of application.html.erb, which loads the application.css and application.js. This is what these two lines of code does.
<%= stylesheet_link_tag 'application', media: 'all' %>
<%= javascript_include_tag 'application' %>
These two files, there is a line require_tree . which loads all the files in the corresponding directory:
app/assets/javascript
app/assets/stylesheets
I usually use public folder only for external libraries when I am not using a CDN. And you will need to explicitly include them in the application.js and application.css file.
I can't figure out how make certain .scss files work with certain views. I removed the *= require_tree . from the application.css.scss but I'm not sure where to go from there. The stylesheet_link_tag doesn't seem to recognize .scss files. What tag can I use to import .scss files to views?
I also tried creating a different controller for the different view but after I removed the require_tree the controller doesn't use the .scss file that was automatically generated with it.
In application.css remove *= require_tree.
In application.html add:
<head>
<%= yield :stylesheets %>
</head>
And on every page render:
<% content_for :stylesheets do %>
<%= stylesheet_link_tag "your file" %>
<% end %>
The most important piece you are probably missing is that Sprockets won't serve any asset, mainly the css and js need to be declared in your asset manifest. Quoting the docs:
If you have other manifests or individual stylesheets and JavaScript files to include, you can add them to the precompile array in config/initializers/assets.rb:
Rails.application.config.assets.precompile += ['admin.js', 'admin.css', 'swfObject.js']
Use the expected resulting name (with .css extension) and not the source file (with the .scss extension).
There is a way to organize your assets based on controller.
Rails guide has a section about it.
According to it you can create app/assets/stylesheets/projects.css.scss file for your ProjectsController and include it like this:
<%= stylesheet_link_tag params[:controller] %>
When doing this, ensure you are not using the require_tree directive, as that will result in your assets being included more than once.
Action based stylesheets can be created similarly:
<%= stylesheet_link_tag "#{params[:controller]}/#{params[:action]}" %>
if the scss file is in the root of the asset folder then
add line to your view file
=stylesheet_link_tag 'your_scss_file_name'
in \config\initializers\assets.rb
add this line
Rails.application.config.assets.precompile + =% w (your_scss_file_name.css)
I've got a folder of js files that I want to include only when I'm on my dashboard page(or controller).
Can I exclude that folder from my application.js's //= require_tree . file and only include it in my dashboard?
You can have application.js require only some files, rather than the everything-and-the-kitchen-sink approach of require_tree .
For instance, make a directory structure like this:
javascripts/
application.js
special.js
common/
foo.js
bar.js
special/
other.js
Then have application.js only include files in the "common" directory by using
= require_tree ./common
Meanwhile, "special.js" (find a better name, obviously), require everything in "special"
= require_tree ./special
Then you'll have to tell Rails that "special.js" should be pre-compiled by the asset pipeline (if you do use asset precompilation). This is done in config/production.rb, and there's already a commented line there showing to to do it. So just uncomment and edit that line, and you should get:
config.assets.precompile += %w( special.js )
If you don't do this, the precompilation will only look at application.js (the default)
Finally, in the relevant views, you can include the special JS by saying
<%= javascript_include_tag "special" %>
You can just place that at the bottom of the file
You can create another js file - dashboard.js, and include it only for dashboard controller
<% if current_page?(:controller => 'dashboard') %>
<%= javascript_include_tag 'dashboard' %>
<% else %>
<%= javascript_include_tag 'application' %>
<% end %>
In your environments/production.rb just add
config.assets.precompile += %w(dashboard.js)
Im very new to ruby, learning from some tutorials in a book i bought. I'm aware the books going to date quick and i think possibly already has.
I'm trying to get the follow code to load my stylesheets and my js to the page.
<!DOCTYPE html>
<html>
<head>
<title>Depot</title>
<%= stylesheet_link_tag "application" %>
<%= javascript_include_tag :defaults %>
<%= csrf_meta_tags %>
</head>
<body>
<%= yield %>
</body>
</html>
However this is not working, when i load my rails server and locally view my app from the tut, the css and js are both not loading. There is no reference to them in the head. Is this a date way to do it or perhaps something else is wrong? Any help would be appreciated, like i said im totally new and not a dev by trade so go easy on me.

Using rails 1.9.3-p0
First of all I advise you to look for information on asset pipeline for rails 3 ( you can start with Railscast)
To load your js files change
<%= javascript_include_tag :defaults %>
to
<%= javascript_include_tag "application" %>
and your application.js should be sth like
// This is a manifest file that'll be compiled into including all the files listed below.
// Add new JavaScript/Coffee code in separate files in this directory and they'll automatically
// be included in the compiled file accessible from http://example.com/assets/application.js
// It's not advisable to add code directly here, but if you do, it'll appear at the bottom of the
// the compiled file.
//
//= require jquery
//= require jquery_ujs
//= require_tree .
the last line loads your js files from assets folder
