Carrierwave gem Secure File Path no puede leer el error del archivo

Question

Traté de seguir la ''Carga segura'' en la onda portadora, lo que es un poco confuso porque he personalizado la ruta del archivo y todo un poco. Cuando intento ejecutar la aplicación, aparece el error "No se puede leer el archivo".

Aquí está la ruta:

match "/uploads/tobereviewed/:user.:username.downcase/:basename.:extension", :controller => "photos", :action => "uploaded", via: :get

El sotre_dir del cargador:

class SubmitUploader < CarrierWave::Uploader::Base

def store_dir
  "uploads/tobereviewed/#{model.user.username.downcase}"
end

Inicializador carrierwave.rb:

    CarrierWave.configure do |config|
      config.permissions = 0600
      config.directory_permissions = 0700
      config.root = Rails.root
    end

Controlador de fotos:

    def uploaded

        file = Submit.first

        send_file "#{Rails.root}/uploads/tobereviewed/#{file.user.username.downcase}/#{file.id}"
    end

El registro de error completo:

Actualización:

Establecí la ruta de archivo correcta de esta manera:

send_file "#{file.filename.file}"

Pero luego da este error:

Cannot read file #<CarrierWave::SanitizedFile:0x007f570c2b9e58>

¿Son correctas mis rutas?

Answer 1

Según su configuración, CarrierWave debe guardar su archivo dentro de "/home/pubudu/Projects/istockseller/public/uploads/tobereviewed/thpubs/#{model.user.username.downcase}/somefile.ext"

Entonces, idealmente tu código debería ser

send_file "#{Rails.root}/public/#{file.image.url}"

Suponiendo que su columna de carga es imagen.

Answer 2

Instalar el depurador en la acción del controlador.

def uploaded
  file = Submit.first

  debugger

  send_file "#{file.filename.file}"
end

Ahora, solicite la acción nuevamente y vaya a la consola del depurador. Un consejo aquí es abrir "irb" dentro del depurador. Simplemente escriba "irb" y presione enter.

Vea lo que está devolviendo file.filename.file. Creo que es una ruta no válida, así que verifique si el archivo existe en su sistema de archivos. Luego, puede reproducir el siguiente paso (send_file) y verificar el registro de errores.

Luego te aconsejo que abras el código fuente de la gema CarrierWave en tu computadora y encuentres qué está mal con tu código.

En su terminal, vaya a su directorio de proyectos y ejecute:

bundle show carrierwave

Esto le imprimirá la ruta de la fuente de la gema carrierwave que está utilizando. Ábralo en su editor y encuentre lo que está mal con su código, de acuerdo con el registro de errores.

Propina

Si proporciona el registro de errores actual (después de su actualización), podemos ayudarlo mejor.

Cannot read file #<CarrierWave::SanitizedFile:0x007f570c2b9e58>

no es suficiente. El backtrace completo sería mejor que esta "línea" de código (use pastebin siempre que sea posible).
