File upload to Amazon S3 using paperclip

Question

I'm uploading files to S3 using paperclip so would like to know if i can set the path something like,

:path => "/advertisements/:username/:filename”

the thing is that :usename is from other model; i'm uploading files on model_2 and :username comes from model_1 . How can i set the path to indicate the :username

Sample :

:path => "/advertisements/@model_1.username/:filename”

Any ideas?

Thanks in advance!
