Hi,

Is there a way to make the path dynamic using fields from the table that  
paperclip belongs (just like the id)?

Here’s what I have tried.

class Photo \< ActiveRecord::Base  
belongs\_to :event  
belongs\_to :photographer

has\_attached\_file :photo,  
:styles =\> { :thumb =\> “128x128\>”, :original =\>  
“328x328\>” },  
:path =\>  
“:photographer\_id/:event\_id/:id/:style.:extension”

end

Where :event\_id and :photographer\_id are fields from in the Photo model?
