Lighthouse has a new layout. Prefer the old one? Return to the old layout, and switch back any time from the link at the top of each page.

This project is archived and is in readonly mode.

has_many :dependent => :deny

#6199

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".

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