Question

I’ve figured out how to upload files using CarrierWave. I’ve figured out how to then load those files into a textarea for editing. My question is:

How do I update my CarrierWave files once they’ve been edited in a textarea?

Answer 1

Assuming that you store on local disk and that your config is as follows

class User < ActiveRecord::Base
  mount_uploader :avatar, AvatarUploader
end

then in your controller’s action:

@user = User.find params[:id]
File.open(@user.avatar.current_path, 'r+') do |f|
   f.print params[:user][:avatar_textarea]
   f.truncate f.pos
end
