Question

3モデル

class Country < ActiveRecord::Base 
    has_many :regions 

    has_many :assets, :dependent => :destroy 
    accepts_nested_attributes_for :assets 
end 

class Region < ActiveRecord::Base 
    belongs_to :country 
    has_many :appartments 

    has_many :assets, :dependent => :destroy 
    accepts_nested_attributes_for :assets 
end 

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

end 

編集フォームを

<%= f.fields_for :assets do |asset| %> 

     <% if asset.object.new_record? %> 
      <%= asset.file_field :image %> 
     <% end %> 

    <% end %> 

マイ領域コントローラ：

def edit 
@country = Country.find(params[:country_id]) 


# For URL like /countries/1/regions/2/edit 

    @region = @country.regions.find(params[:id]) 
    5.times { @country.region.assets.build } 
end 

は私が

を取得

誰かアイデア？
