paperclip

问题 I'm trying to save a users facebook url into my db, but I get the following error. redirection forbidden: http://graph.facebook.com/1240771104/picture -> https://fbcdn-profile-a.akamaihd.net/hprofile-ak-prn2/t... I've referenced this question but I think he is just calling an image instead of saving it to a db with a create block. Here is my user model... def self.find_for_facebook_oauth(auth, signed_in_resource=nil) user = User.where(:provider => auth.provider, :uid => auth.uid).first if

问题 Currently, I adopt Carrierwave for users to images. However, I hardly find a solution for image security, i.e. how to set image authorisation for the uploaded images to only let certain user in the same group to view? After digging Facebook's implementation, I observe that they inject these params (oh,oe, __gda_) to the image url ?oh=924eb34394&oe=55E07&__gda__=1436393492fc8bf91e1aec5 Is there any similar implementation for carrierwave or paperclip ? Thanks 回答1: I worked quite a bit with this

问题 I am using paperclip to attach multiple files to a Entry object Class Asset < ActiveRecord::Base belongs_to :entry has_attached_file :asset, ... Works wonderfully when user is uploading files via a nested form. However, I have certain instances in which a file is uploaded not via the input form but as a result of a flash audio recorder. Audio is recorded and uploaded asynchronously to my /tmp folder. So I end up with some files on my server that have not been uploaded via paperclip. In these

问题 Hope anyone can help on this! Making use of Paperclip to upload Files to an Application, so two things that i need to cover. 1) What is the best way to link to the File for Download, I am currently linking to the public folder but it is not the best option as it shows the URL which i dont want. Thinking maybe a button_to call be not sure if this is build into Paperclip already. Options. 2) When above is done then the Browser needs to force to download not just open the file, or at least give
