nested attributes paperclip

开发者_开发百科Use paperclip for my images.

Models:

class Country < ActiveRecord::Base
has_many :regions
has_many :assets, :dependent => :destroy
accepts_nested_attributes_for :assets
end

class Asset < ActiveRecord::Base
belongs_to :country
has_attached_file :image,
    :styles => {
      :thumb=> "100x100>",
      :small  => "300x300>",
      :large => "600x600>"
        }   
end

My country index.html looks like this:

countries.each do |country| 
  country.name

I tried this:

link_to( image_tag(country.asset.image.url(:thumb)), country.asset.image.url(:original) )

But I get an error.

Someone ideas, what i am doing wrong?

You have got MANY assets for each country

countries.each do |country| 
  country.name
  country.assets.each do |asset|
    link_to( image_tag(asset.image.url(:thumb)), asset.image.url(:original) )

Or change it to has_one association
