I am trying to change my styles of my scss assets on my ruby on rails project but they are applying just after rake assets:precompile and restarting rails server.
With JS files everything allright and they are changing on fly.
Possible problem is with compass gem.
That is my repo - https://github.com/tanotify/blog
And file development.rb
Rails.application.configure do
# Settings specified here will take precedence over those in config/application.rb.

# since you don't have to restart the web server when you make code changes.

# Do not eager load code on boot.
config.eager_load = false
# Show full error reports and disable caching.
config.consider_all_requests_local = true
config.action_controller.perform_caching = false
# Don't care if the mailer can't send.

# Print deprecation notices to the Rails logger.
config.active_support.deprecation = :log
# Raise an error on page load if there are pending migrations.
config.active_record.migration_error = :page_load
# Debug mode disables concatenation and preprocessing of assets.
# This option may cause significant delays in view rendering with a large
# number of complex assets.
config.assets.debug = true
# Asset digests allow you to set far-future HTTP expiration dates on all assets,
# yet still be able to expire them through the digest params.
config.assets.digest = true

# Checks for improperly declared sprockets dependencies.
# Raises helpful error messages.

# Raises error for missing translations
# config.action_view.raise_on_missing_translations = true
config.action_mailer.default_url_options = { host: 'localhost', port: 3000 }
end
Found solution! In config/environments/development.rb added line:
config.serve_static_assets = false

I've been banging my head against the wall on that one for a couple of days now.
My app is running super slow in development mode. A good amount of time is spent on serving the assets (especially images). Each request is extremely slow, taking up to 7s to load a simple 50kb jpeg. Total page load time can be up to a couple of minutes...
I suspect there is a link with auto-loading of the code, since when I turn on classes caching my stuff is loaded much much faster (a few hundred ms maximum). That's not a solution though, since I need to be coding, I can't restart the server everytime I make a change.
Here's my config/development.rb
Rails.application.configure do
# Settings specified here will take precedence over those in config/application.rb.

config.action_mailer.default_options = {from: 'no-reply#example.com'}
config.web_console.whitelisted_ips = '0.0.0.0/0.0.0.0'
end
and initializers/assets.rb
# Be sure to restart your server when you modify this file.
# Version of your assets, change this if you want to expire all your assets.
Rails.application.config.assets.version = '1.0'
# Rails.application.config.assets.precompile += %w( jquery.Jcrop.min.scss )

# Rails.application.config.assets.precompile += %w( search.js )

Rails.application.config.assets.paths << path
end
Any insight would be much appreciated!
Many issues can happens in your application, for example it can be N+1 queries or some slow code, HTTP queries into other site or big assets bundle. So I suggest use profiler it will show bottleneck in your code. See list popular profilers below:

The logout feature in my Rails application appears to be working when I run the app locally using localhost:3000; however, when I logout on the production server it is directing me to http://example.com/users/logout and then when I go to http://example.com I am still logged in.
I pushed all my changes up to the git repo and both dev / prod are both running the same source code. I am not sure why the prod box isn't logging the user out when they click the logout link.

The logout behavior appears to be working now. I put //= require jquery_ujs below //= require jquery in the application.js file and now I am able to logout on the prod box. Thanks for the help guys.
my team and i have been trying to figure this one out for weeks to no avail. Every time we precompile our assets on our production server, our application will begin to load all of our assets twice (once as a precompiled script, and then again as each asset individually). This problem usually occurs between 2-5 days after the precompile (in other words, it works for a few days before breaking). I'm really not certain why this is happening.
I have seen a lot of other people with the same issue, but their issues are always pertaining to the development environment. However, our application's environment is in production.
here is our method for precompiling:
rake assets:clean
rake assets:precompile
here is my /config/environment.rb:
# Load the rails application
require File.expand_path('../application', __FILE__)
ENV['RAILS_ENV'] ||= 'production'
# Initialize the rails application
Myapp::Application.initialize!
here is my /config/environments/production.rb:
Myapp::Application.configure do
# Settings specified here will take precedence over those in config/application.rb
# Code is not reloaded between requests
config.cache_classes = false
# Full error reports are disabled and caching is turned on
config.consider_all_requests_local = false

# Disable Rails's static asset server (Apache or nginx will already do this)
config.serve_static_assets = false
# Compress JavaScripts and CSS
config.assets.compress = true
# Don't fallback to assets pipeline if a precompiled asset is missed
config.assets.compile = true
# Generate digests for assets URLs
config.assets.digest = true
# BEGIN ICONIC PRECOMPILE ISSUE FIX

# config.active_record.auto_explain_threshold_in_seconds = 0.5
end
and, although i don't see why you would need it, here is my /config/environments/development.rb:
Myapp::Application.configure do
# Settings specified here will take precedence over those in config/application.rb
# In the development environment your application's code is reloaded on
# every request. This slows down response time but is perfect for development
# since you don't have to restart the web server when you make code changes.

# Do not compress assets
config.assets.compress = false
# Expands the lines which load the assets
config.assets.debug = true
end
***UPDATE*
as per the suggested answer, I have modified my environments/production.rb. it now looks like this:

end
instead of fixing my problem, all of my assets are now loading twice immediately after precompiling. I'm not sure what I'm doing wrong here.
here are the commands i'm running:
rm -rf public/assets
rake assets:clean
rake assets:precompile
any insight would be greatly appreciated. thanks!
Maybe disabling the live compilation of assets on production could fix your issue.
In your config/environments/production.rb set:
config.assets.compile = false
Take a quick look at this question. It may clarify the "after a few days" part of the issue.
GL & HF
You say that all of your assets are being loaded once from application.css / application.js and then again from their individual files. From what you said, it sounds like you have a bunch of <script> and <style> tags in your <head> element - is that true? That should only happen when you have config.assets.debug = true. In production, the individual files should not appear there at all. You should only have application.css and application.js.
This makes me think that something about your production configuration is wrong or that the wrong environment configuration is being used on your server.
(It could also happen if you added links to the individual files in your layout. Are you doing that?)
It would be easier to debug if you provided the <head> element of your document + the head section of your application layout (or whatever layout you're using).
A few thoughts:
Is your server setting RAILS_ENV=production?
When you compile your assets on your production machine, are you setting RAILS_ENV=production for the rake task?
Is your clock correct on your production machine?
Are your assets really being loaded twice, or are you just seeing JS callbacks fire multiple times? If you're using Turbolinks, any JS in the body of your document that attaches on-document-ready callbacks will begin firing multiple times once you have clicked on any turbolinks-enabled link (but not after a fresh load).
You still have "config.assets.compile = true" in your updated config. You shouldn't need that if you're precompiling assets, and it can cover up problems, so I would suggest changing it back to false.
Here is the assets config I'm using for production apps:
# Disable Rails's static asset server (Apache or nginx will already do this)
config.serve_static_assets = false
# Compress JavaScripts and CSS
config.assets.compress = true
# Don't fallback to assets pipeline if a precompiled asset is missed
config.assets.compile = false
# Generate digests for assets URLs
config.assets.digest = true
Please try with that config and keep us updated.
I'm running in development mode. I'm editing .css files but not seeing changes. If I go to public/assets/ and rename application.css, I see changes (it can't find any styles). Why would it be using that file? Isn't that for production mode? I don't want to pre-compile all the time in dev mode. thanks. Environment files added below.

As default, Rails will serve assets within /public and not compiling live, if these assets exists.
To get rid of it, either delete the assets within the public dir,
or add the following line into you config/environments/development.rb
config.serve_static_assets = false
config.serve_static_assets configures Rails itself to serve static
assets. Defaults to true

What version of rails are you running? Is this an app that upgraded from 2.x or 3.0.x to 3.1 or 3.2? This almost sounds like this app was pre-asset pipline. Here is a good tutorial on upgrading from pre-asset pipline to asset-pipline...
http://railscasts.com/episodes/282-upgrading-to-rails-3-1
...also here is a good basic tutorial for asset pipeline...
http://railscasts.com/episodes/279-understanding-the-asset-pipeline
I recently updated my Rails to 3.1.
Here's a part where I added:
<%= asset_path('logo_symbol.png') %>
This renders /assets/logo_symbol.png which works perfectly fine in development environment. However, when i push the code to production on heroku, it shows a broken image, with the url: assets/logo_symbol-135ddc8db2c9b59f032bed7db520137a.png. I am guessing the new name is for the reason of some optimization.
It is however interesting to note that when I go to the assets/logo_symbol-135ddc8db2c9b59f032bed7db520137a.png url on production, I see a blank page, but when I change that url to anything random, like adding numbers to it, it shows a page not found. So clearly it is finding something on that url. It also shows a blank page when I go to /assets/logo_symbol.png directly on production/heroku.
If this is any help, heroku does not precompile successfully when I push the code and heroku's documentation says that there is currently no work around for that issue.
Any help in this will be greatly appreciated.

I have compared my config files with the rails documentation for 3.1 and seems like I have all the defaults needed. However I am still seeing no image. Any help will be much appreciated
Remove this line from production.rb:
config.action_dispatch.x_sendfile_header = "X-Sendfile"
You should also align the settings in your config files with those in section 9 of the pipeline guides.
Sendfile headers contain information for the upstream webserver of where to find the file (on the file system) to serve it. This removes the load from the backend (Rails/Sprockets). When sendfile is on the HTTP response contains no body (it is zero length) which is why you see nothing.
On heroku the nginx servers do not have access to the application filesystem, so this won't work.
See this note on the Heroku dev site re sendfile.
If you are using heroku, this document outlines the best options for using the pipeline effectively.
You need to do two things to resolve it.
First, change these two lines from false to true in production.rb file.
config.assets.compile = true
config.assets.digest = true
Second, if you've syntax like this for your images
background: url("imgo.jpg")
Change it to
background: image-url("image.jpg")
I hope it does your job.
