Save your attachments first to filesystem and then save async to your model
Add this line to your application's Gemfile:
gem 'async_paperclip_uploader'And then execute:
$ bundle
Or install it yourself as:
$ gem install async_paperclip_uploader
First, call AsyncPaperclipUploader::Temporary.new passing the model object, the related attachment attribute, and the uploaded file. e.g.:
AsyncPaperclipUploader::Temporary.new(@user, 'avatar', uploaded_file).call
Next, create the sidekiq job class, which should follow the following name convention: object class name + UploadJob, e.g.:
UserUploadJob
In this class, you must receive the attributes object_id, attribute and filepath. e.g.:
class UserUploadJob
include Sidekiq::Worker
def perform(user_id, attribute, filepath)
end
end
Inside perform method, you will want to call AsyncPaperclipUploader::Permanent.new, which expects to receive the object class name, the object id, the attribute, and the filepath. e.g.:
def perform(user_id, attribute, filepath)
AsyncPaperclipUploader::Permanent.new('User', user_id, attribute, filepath).call
end
If you want a callback to be ran, the call method accepts a block. e.g.:
AsyncPaperclipUploader::Permanent.new('User', user_id, attribute, filepath).call do
# you callback here
end
Besides all that, it is necessary for your project to have a environment variable named FILE_UPLOAD_STAGING_DIR which should contain a path for where you want the images to be saved temporarily before the proper upload on your model.
