Question

I am having an issue when trying to destroy an active record instance.

It involves the following AR

class Client < ActiveRecord::Base     has_many :phone_numbers, :dependent => :destroy     has_many :email_addresses, :dependent => :destroy     has_many :user_clients , :dependent => :destroy     has_many :users, :through => :user_clients  end  class UserClient  < ActiveRecord::Base belongs_to :user belongs_to :client , :dependent => :destroy has_many :instructions, :dependent => :destroy end 

When performing a destroy on a Client instance I am given the following error

@dead_man = Client.find(params[:id]) @dead_man.destroy => uninitialized constant UserClient::Instruction 

I am really not sure where this error is coming from. Any help is greatly appreciated!

Answer 1

It’s not finding your Instruction model. Make sure it’s in the models directory, appropriately named, extends ActiveRecord::Base, etc.

Also, you should remove the :dependent => :destroy from the belongs_to :client line in the UserClient model, unless you really want deletion of a user_client to result in deletion of the client. It sounds like it should be the other way around, and that’s already set up in the Client model.
