Is there any way to destroy dependencies only after checking condition? This is my Model subject_type.rb

class SubjectType < ActiveRecord::Base
  has_many :subjects, :dependent=>:destroy
  validates_presence_of :name
end

If subject_type_id is present in subject table , dependency should not work,

write a method with a callback of `before_destroy` and in this method you can check condition whatever you want. This callback will be in subject.rb – Vrushali Pawar Jul 24 '15 at 12:08
have you include `belongs_to :subject_type` in Subject model? – Uday kumar das Jul 24 '15 at 12:11
