How to select image size for paperclip when using act_as_api

Question

I'm using the Paperclip gem and act_as_api gem to configure my API. I have a attribute called image in Product model

When using act_as_api with the following definition:

class Product < ActiveRecord::Base

  ...
  acts_as_api

  api_accessible :public do |t|
    t.add :id
    t.add :name
    t.add :price
    t.add :image
  end

 ....

How can I decide how to set the image size like (:medium, :thumb etc) which paperclip provides in the api template?

Answer 1

You can pass a lambda to the add call like this:

t.add lambda{|product| product.image.url(:medium) }, :as => :image
