ruby on rails - Paperclip.interpolates randomly not returning a value -


i have following paperclip setup in model:

  #paperclip photo   has_attached_file :photo,                     :styles => {                       :large => '1024x758>',                       :medium => "200x150#",                       :small => "50x50>"                     },                     :default_style => :original,                     :default_url => '/images/:attachment/default_:style.png',                     :path => ":instance_id/:attachment/:id/:version/:style/:basename.:extension",                     :storage => :s3,                     :s3_credentials => file.join(rails.root, 'config', 's3.yml'),                     :s3_protocol => 'https'

for instance_id have following:

paperclip.interpolates :instance_id |attachment, style|    def instance_id(attachment, style)     attachment.instance.instance_id   end  end

what's happening when first fire server, i'm noticing 404s images. had thought amazon s3, looked urls, , noticed instance_id not being returned paperclip.interpolates.

any idea why? have experienced this?

thanks

if understand correctly you're trying achieve, following should work:

paperclip.interpolates :instance_id |attachment, style|   attachment.instance.instance_id end

fyi: interpolates proc defines method, doesn't something...

hope helps,

peter
