I have a staging environment for my application. I wanted to enable assets precompilation, but there was no clear way for me to do this. I ended up copying over many lines in my environments/production.rb file to environments/staging.rb
current staging.rb
Dezzmo0003::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.
config.cache_classes = false
# 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.
config.action_mailer.raise_delivery_errors = false
# my settings to get assets compiled on staging
config.serve_static_assets = false
config.assets.js_compressor = :uglifier
config.assets.css_compressor = :sass
config.assets.compile = false
config.assets.digest = true
config.assets.version = '1.0'
config.log_level = :info
config.assets.precompile += %w( landing.js pages.js users.js )
config.i18n.fallbacks = true
config.active_support.deprecation = :notify
config.log_formatter = ::Logger::Formatter.new
# 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
config.action_mailer.default_url_options = { :host => 'localhost:3000' }
end
my question is. Where can I look up all these features and understand what they do?
The best place to look up the majority of the config settings for a Rails app is the official Rails configuration guide. They give most of the available config settings in that document and what they do.
If there's one that you don't find in that doc but is in your config file, I'd suggest just Googling the configuration variable (e.g. Google: config.assets.debug) and see what people say about it.

In development my all of my images, CSS and JS are loading fine. In production, my CSS and JS are loading fine. Background images load fine through CSS, and images written as:
image_tag "foo.png"
also load fine and show a fingerprint. However, images written as:
image_tag #test_question.question.image
are not fingerprinted in production (the image name is recorded in the database). However, this works fine in development.
In development I see:
<img src="/assets/picture1-a2bac24ba737cf267b5cc29f9fdaea33.jpg">
In production I see:
<img src="/images/picture1.jpg">
Assets including the images are compiled and fingerprinted in appropriate directories on my production server, they are just not fingerprinted or called correctly in the view. I am using Rails 4.2, nginx and unicorn, and deploying with Capistrano 3.2.
Edit:
I have image subdirectories. The following is in my initializers:
initializers/assets.rb
Dir.glob("#{Rails.root}/app/assets/images/**/").each do |path|
Rails.application.config.assets.paths << path
end
When I comment this out, the behaviour is the same in development as in production. So, I suppose that the problem is that this code is not working / being read in the production environment. Any suggestions?

I really can't see what the problem is here. Any suggestions?
I am trying to figure out why my application.css.scss file is not precompiling correctly on my staging environment. I have tried to replicate the error locally by replacing my local environments file to be the same as my staging one. Everything still works on development after precompiling (but not uglified which is not expected) even though I am using the staging environments settings for my local.
My settings are below

Note
I have cleared my assets using rake assets:clean RAILS_ENV=[environment] and rake assets:clobber RAILS_ENV=[environment]
I have also tried to delete the files manually
I have restarted the server on multiple occasions
This has been an intermitted error that seems to have popped up a couple of times, but it randomly disappears
So I guess I have two questions
Why can't I replicate this locally? (this would be a huge help)
Why is it happening in the first
place?
Any input appreciated.
After more investigation and looking into the public/assets more it seems the css file was being generated, but the URL was incorrect to the file. It seems I needed to update the default css_compressor to sass
config.assets.css_compressor = :sass
I would have thought this would be defaulted already, but I guess not.
Still not sure why I can't replicate this locally though
I'm using Rubinius 2.2.10 and Rails 4.1.6.
since upgrading from rails 3.2, my development environment takes a very long time to load with sprockets' javascript_include_tag whenever the javascript changes. 44 seconds. (I'm using sprockets-2.11.0)
in my development.rb there is this option:
# This option may cause significant delays in view rendering with a large
# number of complex assets.
config.assets.debug = true
but even if I set it to false it takes the same amount of time.
There is a fair bit of javascript in the app (bootstrap and datatables), but it never took that long on Rails 3.2. Any Idea why this is happening and how to speed it back up?

I only need it for production anyway so no reason for it to be in development.rb.
I am trying to run Phusion Passenger and this is the furthest I got. When it loads up on the website it comes up

[deprecated] I18n.enforce_available_locales will default to true in the future. If you really want to skip validation of your locale you can set I18n.enforce_available_locales = false to avoid this message.
Application.initialize!... !> Error
Where do I put I18n.enforce_available_locales = false and will this solve my issue?
I doubt it will solve the error.
You need to put
I18n.enforce_available_locales = false
into your application.rb file so that it looks like this
...
module FoodDump
class Application < Rails::Application
...
I18n.enforce_available_locales = false
...
end

I have an app that works fine locally, but than I try to push to heroku and the root_to route doesn't work.
I've gone through and looked at all the other posts for this, but none of them are for the route_to file and non of the fixes I have found online are working.
I have activeadmin installed so I'm not sure if that is affecting it. I'm using Devise to handle users.
Please help, this is a simple site, I'm not sure why it's causing so much trouble.

Try putting the root route first. That's typically recommended because it's usually the most-accessed route in the application.
