destroy dependent data without destroying original record in rails -

is there easy way destroy data associated particular record, without destroying original record. example, if have

class user < activerecord::base   has_many: pets, dependent: :destroy   has_many: houses, dependent: :destroy end  class pet < activerecord::base   belongs_to :user end  class house < activerecord::base   belongs_to :user end 

if wanted delete user , pets , houses, like:

user = user.first user.destroy 

but if want keep user, want delete pets , houses? there easy way that?

you have manually, callback example.

class user     {callback} :destroy_pets     private     def destroy_pets      self.pets.delete_all       end  end
