Carrierwave gem Sicherer Dateipfad Kann Dateifehler nicht lesen

Question

Ich habe versucht, den "Secure Upload" in Trägerwelle zu folgen, die ein bisschen verwirrend ist, weil ich den Dateipfad und alles ein bisschen angepasst habe. Wenn ich versuche, die App auszuführen, erhalte ich den Fehler "Datei kann nicht gelesen werden".

Hier ist die Route:

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

Die sotre_dir von Uploader:

class SubmitUploader < CarrierWave::Uploader::Base 

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

carrierwave.rb initializer:

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

Fotos Controller:

def uploaded 

     file = Submit.first 

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

Der vollständige Fehlerprotokoll:

127.0.0.1 - - [27/Nov/2014:18:19:09 +0530] "GET /uploaded HTTP/1.1" 500 - 0.0743 

Update:

stelle ich die korrekten Dateipfad wie folgt aus:

send_file "#{file.filename.file}" 

Aber dann gibt es diesen Fehler:

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

Ist meine Routen richtig?

Answer 1

Wie pro Ihre Setup CarrierWave sollte Ihre Datei in "/home/pubudu/Projects/istockseller/public/uploads/tobereviewed/thpubs/#{model.user.username.downcase}/somefile.ext" speichern

also im Idealfall sollten Sie den Code

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

sein Spalte Angenommen, Ihre Upload Bild.

Answer 2

Debugger in der Aktion des Controllers einrichten.

def uploaded 
    file = Submit.first 

    debugger 

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

Jetzt die Aktion erneut anfordern und zur Debugger-Konsole gehen. Ein Tipp hier ist, "irb" im Debugger zu öffnen. Gib einfach "irb" ein und drücke Enter.

Sehen Sie, was file.filename.file zurückgibt. Ich glaube, es ist ein ungültiger Pfad, also überprüfe, ob die Datei in deinem Dateisystem existiert. Dann können Sie den nächsten Schritt (send_file) reproduzieren und das Fehlerprotokoll überprüfen.

Ich würde Ihnen dann raten, den Quellcode von CarrierWave gem in Ihrem Computer zu öffnen und herauszufinden, was mit Ihrem Code nicht stimmt.

In Ihrem Terminal, gehen Sie zu Ihrem Projektverzeichnis und laufen:

bundle show carrierwave 

Dies Sie den Pfad des carrierwave Juwel der Quelle gedruckt werden Sie verwenden. Öffnen Sie es in Ihrem Editor und finden Sie, was mit Ihrem Code falsch ist, gemäß dem Fehlerprotokoll!

Tip

Wenn Sie das aktuelle Fehlerprotokoll (nach dem Update) zur Verfügung stellen, können wir Ihnen helfen, besser.

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

ist nicht genug. Die vollständige Backtrace wäre besser als diese "eine Zeile" Code (benutze Pastebin wann immer möglich).
