Carrierwave gem Percorso file sicuro Impossibile leggere l'errore del file

Question

Ho cercato di seguire il "Caricamento sicuro" nell'onda portante, che è un po 'confuso perché ho personalizzato il percorso del file e tutto un po'. Quando provo a eseguire l'app, visualizzo l'errore "Impossibile leggere il file".

Ecco il percorso:

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

La sotre_dir di 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 

Foto regolatore:

def uploaded 

     file = Submit.first 

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

Il log di errore completo:

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

Aggiornamento:

ho impostato il percorso di file corretto in questo modo:

send_file "#{file.filename.file}" 

Ma poi si dà questo errore:

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

Sono i miei percorsi corretta?

Answer 1

Come per la configurazione CarrierWave dovrebbe salvare il file all'interno di "/home/pubudu/Projects/istockseller/public/uploads/tobereviewed/thpubs/#{model.user.username.downcase}/somefile.ext"

Così, idealmente il codice dovrebbe essere

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

Supponendo che la vostra colonna di upload è immagine.

Answer 2

Setup debugger nell'azione del controller.

def uploaded 
    file = Submit.first 

    debugger 

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

Ora, richiedi nuovamente l'azione e vai alla console del debugger. Un consiglio qui è di aprire "irb" all'interno del debugger. Basta digitare "irb" e premere invio.

Vedere che file.filename.file sta restituendo. Credo che sia un percorso non valido, quindi controlla se il file esiste nel tuo filesystem. Quindi, è possibile riprodurre il passaggio successivo (send_file) e controllare il log degli errori.

Vorrei quindi consigliarvi di aprire il codice sorgente di CarrierWave gem nel vostro computer e scoprire cosa c'è di sbagliato nel vostro codice.

nel terminale, accedere alla directory del progetto ed eseguire:

bundle show carrierwave 

Questo stamperà la strada della fonte gemma carrierwave che si sta utilizzando. Aprilo nel tuo editor e trova cosa c'è di sbagliato nel tuo codice, in base al log degli errori!

Tip

Se si fornisce il log degli errori corrente (dopo l'aggiornamento), ci può aiutare a meglio.

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

non è sufficiente. Il backtrace completo sarebbe migliore di questa "una riga" di codice (usa pastebin quando possibile).
