I re-scaffolded everything and now the class that used to be called sub_category is now just subcategory. The same error appears as in my first post. And the following is the inside of the edit function in the subcategories_controller: @subcategory = Subcategory.find_by_id(params[:id]) @category = Category.find(:all) the model file (subcategory.rb): class Subcategory < ActiveRecord::Base belongs_to :category end Any advice? -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
