Hi,
I'm following the Polymorphic Associations test， issue as following.
*****
class Product < ActiveRecord::Base
has_many :images, :as=>:imageable
end
-------
class User < ActiveRecord::Base
has_many :images, :as=>:imageable
end
-------
class Image < ActiveRecord::Base
belongs_to :imageable, :polymorphic => true
end
**migration:
class CreateImages < ActiveRecord::Migration
def self.up
create_table :images do |t|
t.integer :imageable_id
t.string :imageable_type
t.string :name
t.timestamps
end
end
def self.down
drop_table :images
end
end
**rending views/images/show.html.erb
<p>
<b>OwnerName:</b>
<%= @image.imageable%>
</p>
*****
when i rendering the http://localhost:3000/images/1, the wrong message
as following:
*****
NameError in Images#show
