Question

I’m using mailboxer gem and I don’t know how to use it with Paperclip (Message Class).

Using Paperclip with a User class is:

class User < ActiveRecord::Base
  has_attached_file :picture
end

How can I add has_attached_file to the Message class (there is no message.rb in models)?

Thank you.

Two solutions:

• use the built-in attachment made with carrierwave (source)

• monkey patch the Message model:

in an initializer do:

Message.class_eval do

  #your paperclip code goes here

end

And don’t forget migrations!
