ruby on rails 4 - present - rails 4 image_tag no se vincula a mis activos de imagen digeridos

the asset image is not present in the asset pipeline

Question

En los carriles 4 mi imagen_tag ("asset / logo.png") no está enlazando al archivo con el compendio, los activos están precompilados también las imágenes que están en público / los activos / *

Mi producción.rb:

Books::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

  # 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 = 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''

  # 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 = true

  # Set to :debug to see everything in the log.
  config.log_level = :debug

  # 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 )
  config.assets.precompile += [/^[a-z0-9]/w+.(css|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

end

Pasé 2 horas tratando de resolver esto totalmente sin opciones, ¿por qué no funciona?

Answer 1

Acabo de encontrar este problema y la solución es bastante simple: elimine la parte "/ asset" de la ruta de entrada. Rails sabe dónde mirar cuando usa image_tag. Asegúrese de colocar el archivo de imagen en / asset / images.

Answer 2

Asegúrese de no haber escrito mal el nombre, si Rails puede encontrar la imagen en las carpetas de activos, se vinculará a la ruta de los activos compilados. Si no puede encontrar la imagen, se vinculará a la carpeta de imágenes.

image_tag("logo.png") 
=> ''/assets/logo-f2c87c4e3fda671a619ccb7...png''  # if image exists
=> ''/images/logo.png''   # if image does not exists in asset folder

Answer 3

Ponga su imagen en "activos / imágenes".

En su opinión:

image_tag "my_image.png", class: "optional_class"
