has_many :dependent => :deny

Reported by François Beausoleil | December 20th, 2010 @ 02:39 PM

I have a case which would be perfect for this.

db/schema.rb

create_table "campaigns" do |t|
t.integer "advertiser_id", :null => false # ... end

class Advertiser < ActiveRecord::Base
has_many :campaigns, :dependent => :deny end

I'd see the :deny option as adding validation that would check if the collection is empty, and if not, then generate something along the lines "Campaigns must be empty - delete all to delete this advertiser".

      t.integer "advertiser_id", :null => false
      # ...
    end
    
    # app/models/advertiser.rb
    class Advertiser < ActiveRecord::Base
      has_many :campaigns, :dependent => :deny
    end

    The same issue already exists and is waiting for proper patch since 2008 ;)
