权限被拒绝@ dir_s_mkdir-/ listings

Question

I am not exactly sure what I am doing wrong. Paperclip with S3.

Errno::EACCES in ListingsController#update Permission denied @ dir_s_mkdir - /listings Extracted source (around line #44):

Answer 1

As @tadman said, you are trying to create your attachments outside your application path.

Try changing

Paperclip::Attachment.default_options[:path] = '/:class/:attachment/:id_partition/:style/:filename'

with something like

Paperclip::Attachment.default_options[:path] = ':rails_root/public/system/:class/:attachment/:id_partition/:style/:filename'

or

Paperclip::Attachment.default_options[:path] = "#{Rails.root}/public/system/:class/:attachment/:id_partition/:style/:filename"
