Ruby on Rails paperclip questions

问题

I want to use paperclip to upload files to server. Errors are all cleaned now, but I don't know how to set the upload path.

My code looks like this:

upload class:

  puts has_attached_file :image, :default_url => :file_system
  validates_attachment_content_type :image, :content_type => [:image,    'audio/mpeg', 'application/mp3', 'application/octet-stream']

I want to save uploads in project/public/uploads.

How can I realise this?

回答1:

Then it should look like this:

has_attached_file :image,                     
                    :path => ":rails_root/public/uploads/:filename",
                    :url => "/uploads/:filename"
