问题 I have a weird behaviour in my params whichare passed as utf-8 but the special characters are not well managed. Instead of 1 special character, I have 2 characters: the normal letter + the accent. Parameters: {"name"=>"Mylène.png", "_cardbiz_session"=>"be1d5b7a2f27c7c4979ac4c16fe8fc82", "authenticity_token"=>"9vmJ02DjgKYCpoBNUcWwUlpxDXA8ddcoALHXyT6wrnM=", "asset"=>{"file"=># < ActionDispatch::Http::UploadedFile:0x007f94d38d37d0 @original_filename="Mylène.png", @content_type="image/png",

问题 I try to duplicate a record many time using this code : my_obj = Obj.find_by(id: params[:id]) new_obj = my_obj.dup I use CarrierWave to mount an image to my Obj class Obj < ActiveRecord::Base mount_uploader :image, ObjImageUploader end my first code above, duplicate the obj as well but it doesn't duplicate the image correctly, it shows instead something like Medium 2013 08 04 14354 , so i tried to fix this using new_obj = my_obj.dup new_obj.image = my_obj.image and now it works correctly, the

问题 Carrierwave deletes files after the destruction of the object has been completed: after_commit :remove_avatar! :on => :destroy https://github.com/carrierwaveuploader/carrierwave I have a worker that deletes the files. If one of the workers timeout when deleting a file from S3 I lose track of the files on S3 and my bucket becomes a mess (since my object that had the mounted file is gone from my DB). How should I handle this? Directly call remove_avatar! before my object.destroy and then skip

问题 I've been working on this all night and it makes no sense. I'm adapting an old photo web app to have albums in it. I made "fails" (basically images) a nested resource of albums. I am using carrierwave to upload files to an S3 bucket. the weird thing is: the upload works perfectly fine for the album model (album image), but it doesn't upload for the fail model. I don't see why it'd be a problem that it's a nested resource now. It's not a problem displaying it's that for some reason, it goes

问题 We have a staging server setup to use a different S3 bucket from our production server, but that requires us to manually sync the images between the buckets in order to see images on staging.

UPDATE : I've tried my hand at creating a custom
