Paperclip images failing to save in production rai

问题:

Im have just deployed a rails app which uses Paperclip to handle the file uploads to a linux ubuntu 10.04 server running apache2, passenger, rails 3.2.3 and ruby 1.9.3.

My setup worked perfectly fine in development, however now in production images never save.

i have commented out the following lines in production.rb so that rails deals with the file uploads and also tried using and installing XSendFile.

# 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

and my picture.rb

attr_accessible :photo_file_name, :photo_file_size, :photo_content_type, :photo, :splash_image
  validates_presence_of :photo_file_name, :photo_content_type, :photo_file_size


  has_attached_file :photo,
    styles: {
      thumb: "150x150>"
    },
       url: "/assets/splash_images/:id/:style/:basename.:extension",
       path: ":rails_root/public/assets/splash_images/:id/:style/:basename.:extension"

    validates_attachment_size :photo, :less_than => 25.megabytes
    validates_attachment_content_type :photo, content_type: /image/

Does anyone know what could be going on? many thanks

You need to specify paths if ImageMagick is not installed on the default paths. For windows users, do something like this in initializers/paperclip.rb:

require "paperclip" require 'rbconfig' is_windows = (RbConfig::CONFIG['host_os'] =~ /mswin|mingw|cygwin/)

Paperclip.options[:command_path] = 'C:\ImageMagick' if is_windows Paperclip.options[:swallow_stderr] = false

find the location of "identify" in your imagemagick path and put that in here. Of course, you need to put the linux path in there. (/usr/bin/ ...)

Thanks Meduza and Hugo for pointing me in the right direction. To get the images uploading and saving successfully I had to install Imagemagick on the linux server and also give write permissions to the image path like so:

Append with sudo if not running from root

 apt-get install imagemagick
 apt-get install libmagick9-dev
 gem install rmagick

 chmod -R 777 app/app_name/public/assets/image_folder
