Mistaken duplicate JSON nested object - Rails -

i have rails api returns json using rabl gem. here's /show template extended /index template well.

object @deal attributes :headline, :text, :image, :id, :created_at  child :vendor     attributes :image_url, :id end 

both deal , vendor have images, uploaded through carrierwave/fog s3. problem i'm seeing here returned json includes , image object deal. so:

"deal":{"image":{"image":{"url":"httpxxxxxxxxxxxx"}}}

in contrast, json vendor returns appropriately:

"vendor":{"image_url":"httpxxxxxxxxxxx"}

my uploaders below:

class dealuploader < carrierwave::uploader::base    def store_dir      "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"    end end  # vendor image uploader class imageuploader < carrierwave::uploader::base   def store_dir     "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"   end end 

why getting redundant image object?

try

object @deal attributes :headline, :text, :image_url, :id, :created_at  child :vendor     attributes :image_url, :id end
