Someone else found this before I saw yours, but that is the problem.
I assumed that scaffold would know what the primary key is , because it
was identified in the migrated schema:
schema.rb
create_table "dogs", :primary_key => "dog_id", :force => true do |t|
t.string "color", :limit => 20
t.string "gender", :limit => 20
t.string "dog_name", :limit => 20
end
Thanks for your help!
