Question

I want to configure an upload path for Carrier wave Direct,which I am using to upload files directly to Amazon s3.In app/uploaders/myuploader.rb ,I have,

def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
end

I want to modify this so that,the path looks like,
“uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{User.name}”.
so it will be some thing like,
“uploads/Users/avatar/michael_jordan/..”
Where User is the model in which the uploader is mounted.

I have gone through the source code of Carrier wave Gem in github(https://github.com/dwilkie/carrierwave_direct) and I couldn’t figure out how to pass a value from the active model object to the uploader to create the upload path(key for amazon s3). Is there a way to do this?

Thanks!

Ok.after one month I was forced to work on the same problem and this time I nailed it.Posting my solution here so that it may help others having the same problem,
1)Override store_dir such that it returns an empty string,

def store_dir
 ""
end

2)got to your controller and assign your preferred key to the “key” attribute of your uploader object like,

  @uploader = @player.avatar 
  @uploader.key =@player.name +"/\${filename}"
  #say if player name in is jordan and the filename is jordan.jpg.
  #the uplaod path  now will be   
  #http://bucketname/jordan/jordan.jpg.

here player is the model object,avatar is the property on which the uploader is mounted and the key will be set as playername/filename.

Which was what I was looking for 🙂
