rails not picking up new image in development - ruby-on-rails

I am running into a strange issue. If i add a new image to the images folder and use it on a web page - rails is throwing an error like this.
Asset was not declared to be precompiled in production.
Add Rails.application.config.assets.precompile += %w( spinner60.gif ) to config/initializers/assets.rb and restart your server
This is all happening in development mode only. I am developing locally - and not on any server production or otherwise.
If i reboot the server on local machine - rails picks up the asset and serves it without any complains.
Anybody experience anything like this before? - No changes made to any of the environment or asset files.
Any help will be appreciated.

Which asset debugger configuration is valid when deploying Rails 5.2 to production?

I am planning to deploy my Ruby on Rails 5.2 application behind an Apache reverse proxy (we only have Windows servers). I try switching environment from dev to production:
rails server -e production
The Puma server stars fine, but the default configuration (config/environments/production.rb) serves pages without formatting the layout: css seems not to be applied.
To have it working, I added the following configuration option:
config.assets.debug = true
but it slows down the rendering of pages.
Here is the resulting configuration file for prodution instance:
DataQualityManager::Application.configure do
# Settings specified here will take precedence over those in config/application.rb.
# Code is not reloaded between requests.
config.cache_classes = true
# Eager load code on boot. This eager loads most of Rails and
# your application in memory, allowing both thread web servers
# and those relying on copy on write to perform better.
# Rake tasks automatically ignore this option for performance.
config.eager_load = true
# Full error reports are disabled and caching is turned on.
config.consider_all_requests_local = false
config.action_controller.perform_caching = true
# Enable Rack::Cache to put a simple HTTP cache in front of your application
# Add `rack-cache` to your Gemfile before enabling this.
# For large-scale production use, consider using a caching reverse proxy like nginx, varnish or squid.
# config.action_dispatch.rack_cache = true
# 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
# Disable Rails's static asset server (Apache or nginx will already do this).
config.serve_static_assets = false
# Compress JavaScripts and CSS.
config.assets.js_compressor = :uglifier
# config.assets.css_compressor = :sass
# Do not fallback to assets pipeline if a precompiled asset is missed.
config.assets.compile = true
# Generate digests for assets URLs.
config.assets.digest = true
# Version of your assets, change this if you want to expire all your assets.
config.assets.version = '1.0'
# Specifies the header that your server uses for sending files.
# config.action_dispatch.x_sendfile_header = "X-Sendfile" # for apache
# config.action_dispatch.x_sendfile_header = 'X-Accel-Redirect' # for nginx
# Force all access to the app over SSL, use Strict-Transport-Security, and use secure cookies.
config.force_ssl = false
# Set to :debug to see everything in the log.
config.log_level = :info
# Prepend all log lines with the following tags.
# config.log_tags = [ :subdomain, :uuid ]
# Use a different logger for distributed setups.
# config.logger = ActiveSupport::TaggedLogging.new(SyslogLogger.new)
# Use a different cache store in production.
# config.cache_store = :mem_cache_store
# Enable serving of images, stylesheets, and JavaScripts from an asset server.
# config.action_controller.asset_host = "http://assets.example.com"
# Precompile additional assets.
# application.js, application.css, and all non-JS/CSS in app/assets folder are already added.
# config.assets.precompile += %w( search.js )
# Ignore bad email addresses and do not raise email delivery errors.
# Set this to true and configure the email server for immediate delivery to raise delivery errors.
# config.action_mailer.raise_delivery_errors = false
# Enable locale fallbacks for I18n (makes lookups for any locale fall back to
# the I18n.default_locale when a translation can not be found).
# config.i18n.fallbacks = true
# Send deprecation notices to registered listeners.
config.active_support.deprecation = :notify
# Disable automatic flushing of the log to improve performance.
# config.autoflush_log = false
# Use default logging formatter so that PID and timestamp are not suppressed.
config.log_formatter = ::Logger::Formatter.new
# Store uploaded files locally.
config.active_storage.service = :local
end
Can you help me solving this issue and keep the server performant?
Thanks a lot!

Rails 4: assets are not loading in production

I successfully deployed rails app using capistrano with unicorn and ngnix.
After deploy, assets are not loading. I am unable to figure out how to fix it. I looked around in the internet and tried some of the config changes that are suggested in production.rb. Still unable to figure out.
production.rb
Rails.application.configure do
# Settings specified here will take precedence over those in config/application.rb.
# Code is not reloaded between requests.
config.cache_classes = true
# Eager load code on boot. This eager loads most of Rails and

# For large-scale production use, consider using a caching reverse proxy like
# NGINX, varnish or squid.
# config.action_dispatch.rack_cache = true
# Disable serving static files from the `/public` folder by default since
# Apache or NGINX already handles this.
#config.serve_static_files = true #ENV['RAILS_SERVE_STATIC_FILES'].present?
config.serve_static_files = true
# Compress JavaScripts and CSS.
config.assets.js_compressor = :uglifier
# config.assets.css_compressor = :sass
# Do not fallback to assets pipeline if a precompiled asset is missed.
config.assets.compile = false
# 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.force_ssl = true

# when problems arise.
config.log_level = :debug

# config.action_controller.asset_host = 'http://assets.example.com'

# config.action_mailer.raise_delivery_errors = false
# Enable locale fallbacks for I18n (makes lookups for any locale fall back to

config.i18n.fallbacks = true
# Send deprecation notices to registered listeners.
config.active_support.deprecation = :notify
# Use default logging formatter so that PID and timestamp are not suppressed.
config.log_formatter = ::Logger::Formatter.new
# Do not dump schema after migrations.
config.active_record.dump_schema_after_migration = false
end
update
During cap deploy, the assets:precompile runs by default. It runs without any errors. Also ran it manually on the server, but in vain.
Make sure, in config/environments/production.rb, you have...
config.assets.compile = true
if anyone using rails versions < 4 include this otherwise don't
config.assets.precompile = ['*.js', '*.css', '*.css.scss','*.js.coffee']
After adding this line try to deploy your application your CSS and js file compiles at sever side dynamically.
If it fails to run this command from your command line
RAILS_ENV=production bundle exec rake assets:precompile
Add these precompiled assets to your git.It works fine in production.

Every page returns an error on my Rails production server

When using a production server started with rails s -e production, every page I visit returns this error:
We're sorry, but something went wrong.
If you are the application owner check the logs for more information.
I don't know what the error means, or even if it's the same type of error every time, although it's the same text every time.
Does anyone know why this is happening?

You're forgot to made some production usage preparations for Rails app.
Ensure the user that running your Rails application have permissions to write logs in log directory.
Ensure your secret key and rails env. Secret key used for cookies security. Tou just can create enviroment variable and Rails can retrive it export SECRET_KEY_BASE=$(rake secret) Rails env used to tell you Rails app running in production mode export RAILS_ENV=production
Ensure you DB if configured right. You need to create config/database.yml with your DB adapter configuration, after that run rake db:create and rake db:migrate.
Ensure your assets precompiled. Just run rake assets:precompile
After all of that you can run rails s
But this is not right way to run your Rails app in production. For nice and reliable production you're need to use Nginx as load-balancer and alternative application server such as Puma or Passenger.

nothing changes when making change in assets fiels

I'm trying to make a change in a css file but it seems that it is not responding to it even if a deleted that whole file, it is still loaded in the page,
I've tried to remove the assets folder from public and made
bundle exec rake assets:clean
bundle exec rake assets:precompile
but nothing changed
that's my development config file
Rails.application.configure do
# Settings specified here will take precedence over those in config/application.rb.
config.action_mailer.default_url_options = { host: 'localhost', port: 3000 }
# In the development environment your application's code is reloaded on

How can I tail error logs on centos 6 server for rails app?

I have created and built a server on Digitalocean and its a centos 6 server with nodejs running and rails installed on top of it. Its has nginx and passenger running together and I am deploying with capistrano to ease that process with postgres as the production db to use. Everything is installed okay and the db is set up.
I have deployed the site and the capistrano deploy worked fine with no errors but when I go to the staging site it has an error. I am trying to get the logs for this but I cannot seem to find them. I have tried the /log/staging.log file and I have set the /environments/staging.rb file to look like this:
PopupHub::Application.configure do
# Settings specified here will take precedence over those in config/application.rb.
# Code is not reloaded between requests
config.cache_classes = true
# Full error reports are disabled and caching is turned on
config.consider_all_requests_local = true
config.action_controller.perform_caching = true
# 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
# Version of your assets, change this if you want to expire all your assets.
config.assets.version = '1.0'
# Enable locale fallbacks for I18n (makes lookups for any locale fall back to
# the I18n.default_locale when a translation can not be found)
config.i18n.fallbacks = true
# Send deprecation notices to registered listeners
config.active_support.deprecation = :notify
# Log the query plan for queries taking more than this (works
# with SQLite, MySQL, and PostgreSQL)
# config.active_record.auto_explain_threshold_in_seconds = 0.5
SitemapGenerator.verbose = false
config.assets.paths << Rails.root.join('app', 'assets', 'fonts')
config.autoload_paths += %W(#{config.root}/app/models/ckeditor)
config.assets.precompile += Ckeditor.assets
config.assets.precompile += %w(ckeditor/*)
end
When I go to use tail -f log/staging.log I get nothing but information about a migration with no logging when I refresh the page on the apps ip address.
can anyone help me to see where I can locate the logs properly or get them working?
