class Category < ActiveRecord::Base belongs_to :sector has_and_belongs_to_many :suppliers validates :sector, :name, :presence => true
As you see I have validates :sector, :presence => true. When I create a new Category, if I don't select a sector I have an error page with the message: Couldn't find Sector with ID= But there is the validates, why I don't have the message sector can't be blank? -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
