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?
class Category < ActiveRecord::Base
belongs_to :sector
has_and_belongs_to_many :suppliers
validates :sector, :name, :presence => true

When I create a new Category, if I don’t select a sector I have an
error page with the message:
I don’t know about the others but when associating other tables like this, I don’t do the validations
this way.
i create a method that i can call with validates.
validates :sector_should_not_be_blank
def sector_should_not_be_blank
errors.add(:sector, “can’t be blank”) if sector.nil?
end

Is that error occurring before the save happens, or are you saying that it has saved it with no sector?
