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 (3)
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.
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

# Code is not reloaded between requests.
config.cache_classes = true

# your application in memory, allowing both thread web servers

Pasé 2 horas tratando de resolver esto totalmente sin opciones, ¿por qué no funciona?
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
Ponga su imagen en "activos / imágenes".
En su opinión:
image_tag "my_image.png", class: "optional_class"
